    The |time, |plainTime and |date modifiers have been deprecated and replaced by a unified {time} function.

    The main benefit is that it is no longer necessary to specify the @ symbol when rendering the interactive time element, making it easier to perform a security review of templates by searching for the @ symbol.

    This guide will help you to create a simple package that provides a simple test page. It is nothing too fancy, but you can use it as the foundation for your next project.

    There are some requirements you should met before starting:

    "},{"location":"getting-started/#the-packagexml-file","title":"The package.xml File","text":"

    We want to create a simple page that will display the sentence \"Hello World\" embedded into the application frame. Create an empty directory in the workspace of your choice to start with.

    Create a new file called package.xml and insert the code below:

    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<package xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/2019/package.xsd\" name=\"com.example.test\">\n<packageinformation>\n<!-- com.example.test -->\n<packagename>Simple Package</packagename>\n<packagedescription>A simple package to demonstrate the package system of WoltLab Suite Core</packagedescription>\n<version>1.0.0</version>\n<date>2019-04-28</date>\n</packageinformation>\n<authorinformation>\n<author>Your Name</author>\n<authorurl>http://www.example.com</authorurl>\n</authorinformation>\n<excludedpackages>\n<excludedpackage version=\"6.0.0 Alpha 1\">com.woltlab.wcf</excludedpackage>\n</excludedpackages>\n<instructions type=\"install\">\n<instruction type=\"file\" />\n<instruction type=\"template\" />\n<instruction type=\"page\" />\n</instructions>\n</package>\n

    There is an entire chapter on the package system that explains what the code above does and how you can adjust it to fit your needs. For now we'll keep it as it is.

    "},{"location":"getting-started/#the-php-class","title":"The PHP Class","text":"

    The next step is to create the PHP class which will serve our page:

    1. Create the directory files in the same directory where package.xml is located
    2. Open files and create the directory lib
    3. Open lib and create the directory page
    4. Within the directory page, please create the file TestPage.class.php

    Copy and paste the following code into the TestPage.class.php:

    <?php\nnamespace wcf\\page;\nuse wcf\\system\\WCF;\n\n/**\n * A simple test page for demonstration purposes.\n *\n * @author  YOUR NAME\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n */\nclass TestPage extends AbstractPage {\n    /**\n     * @var string\n     */\n    protected $greet = '';\n\n    /**\n     * @inheritDoc\n     */\n    public function readParameters() {\n        parent::readParameters();\n\n        if (isset($_GET['greet'])) $this->greet = $_GET['greet'];\n    }\n\n    /**\n     * @inheritDoc\n     */\n    public function readData() {\n        parent::readData();\n\n        if (empty($this->greet)) {\n            $this->greet = 'World';\n        }\n    }\n\n    /**\n     * @inheritDoc\n     */\n    public function assignVariables() {\n        parent::assignVariables();\n\n        WCF::getTPL()->assign([\n            'greet' => $this->greet\n        ]);\n    }\n}\n

    The class inherits from wcf\\page\\AbstractPage, the default implementation of pages without form controls. It defines quite a few methods that will be automatically invoked in a specific order, for example readParameters() before readData() and finally assignVariables() to pass arbitrary values to the template.

    The property $greet is defined as World, but can optionally be populated through a GET variable (index.php?test/&greet=You would output Hello You!). This extra code illustrates the separation of data processing that takes place within all sort of pages, where all user-supplied data is read from within a single method. It helps organizing the code, but most of all it enforces a clean class logic that does not start reading user input at random places, including the risk to only escape the input of variable $_GET['foo'] 4 out of 5 times.

    Reading and processing the data is only half the story, now we need a template to display the actual content for our page. You don't need to specify it yourself, it will be automatically guessed based on your namespace and class name, you can read more about it later.

    Last but not least, you must not include the closing PHP tag ?> at the end, it can cause PHP to break on whitespaces and is not required at all.

    "},{"location":"getting-started/#the-template","title":"The Template","text":"

    Navigate back to the root directory of your package until you see both the files directory and the package.xml. Now create a directory called templates, open it and create the file test.tpl.

    {include file='header'}\n\n<div class=\"section\">\n    Hello {$greet}!\n</div>\n\n{include file='footer'}\n

    Templates are a mixture of HTML and Smarty-like template scripting to overcome the static nature of raw HTML. The above code will display the phrase Hello World! in the application frame, just as any other page would render. The included templates header and footer are responsible for the majority of the overall page functionality, but offer a whole lot of customization abilities to influence their behavior and appearance.

    "},{"location":"getting-started/#the-page-definition","title":"The Page Definition","text":"

    The package now contains the PHP class and the matching template, but it is still missing the page definition. Please create the file page.xml in your project's root directory, thus on the same level as the package.xml.

    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/2019/page.xsd\">\n<import>\n<page identifier=\"com.example.test.Test\">\n<controller>wcf\\page\\TestPage</controller>\n<name language=\"en\">Test Page</name>\n<pageType>system</pageType>\n</page>\n</import>\n</data>\n

    You can provide a lot more data for a page, including logical nesting and dedicated handler classes for display in menus.

    "},{"location":"getting-started/#building-the-package","title":"Building the Package","text":"

    If you have followed the above guidelines carefully, your package directory should now look like this:

    \u251c\u2500\u2500 files\n\u2502   \u2514\u2500\u2500 lib\n\u2502       \u2514\u2500\u2500 page\n\u2502           \u2514\u2500\u2500 TestPage.class.php\n\u251c\u2500\u2500 package.xml\n\u251c\u2500\u2500 page.xml\n\u2514\u2500\u2500 templates\n    \u2514\u2500\u2500 test.tpl\n

    Both files and templates are archive-based package components, that deploy their payload using tar archives rather than adding the raw files to the package file. Please create the archive files.tar and add the contents of the files/* directory, but not the directory files/ itself. Repeat the same process for the templates directory, but this time with the file name templates.tar. Place both files in the root of your project.

    Last but not least, create the package archive com.example.test.tar and add all the files listed below.

    The archive's filename can be anything you want, all though it is the general convention to use the package name itself for easier recognition.

    "},{"location":"getting-started/#installation","title":"Installation","text":"

    Open the Administration Control Panel and navigate to Configuration > Packages > Install Package, click on Upload Package and select the file com.example.test.tar from your disk. Follow the on-screen instructions until it has been successfully installed.

    Open a new browser tab and navigate to your newly created page. If WoltLab Suite is installed at https://example.com/wsc/, then the URL should read https://example.com/wsc/index.php?test/.

    Congratulations, you have just created your first package!

    "},{"location":"getting-started/#developer-tools","title":"Developer Tools","text":"

    The developer tools provide an interface to synchronize the data of an installed package with a bare repository on the local disk. You can re-import most PIPs at any time and have the changes applied without crafting a manual update. This process simulates a regular package update with a single PIP only, and resets the cache after the import has been completed.

    "},{"location":"getting-started/#registering-a-project","title":"Registering a Project","text":"

    Projects require the absolute path to the package directory, that is, the directory where it can find the package.xml. It is not required to install an package to register it as a project, but you have to install it in order to work with it. It does not install the package by itself!

    There is a special button on the project list that allows for a mass-import of projects based on a search path. Each direct child directory of the provided path will be tested and projects created this way will use the identifier extracted from the package.xml.

    "},{"location":"getting-started/#synchronizing","title":"Synchronizing","text":"

    The install instructions in the package.xml are ignored when offering the PIP imports, the detection works entirely based on the default filename for each PIP. On top of that, only PIPs that implement the interface wcf\\system\\devtools\\pip\\IIdempotentPackageInstallationPlugin are valid for import, as it indicates that importing the PIP multiple times will have no side-effects and that the result is deterministic regardless of the number of times it has been imported.

    Some built-in PIPs, such as sql or script, do not qualify for this step and remain unavailable at all times. However, you can still craft and perform an actual package update to have these PIPs executed.

    "},{"location":"getting-started/#appendix","title":"Appendix","text":""},{"location":"getting-started/#template-guessing","title":"Template Guessing","text":"

    The class name including the namespace is used to automatically determine the path to the template and its name. The example above used the page class name wcf\\page\\TestPage that is then split into four distinct parts:

    1. wcf, the internal abbreviation of WoltLab Suite Core (previously known as WoltLab Community Framework)
    2. \\page\\ (ignored)
    3. Test, the actual name that is used for both the template and the URL
    4. Page (page type, ignored)

    The fragments 1. and 3. from above are used to construct the path to the template: <installDirOfWSC>/templates/test.tpl (the first letter of Test is being converted to lower-case).

    The ImageViewer is available on all frontend pages by default, you can easily add images to the viewer by wrapping the thumbnails with a link with the CSS class jsImageViewer that points to the full version.

    "},{"location":"javascript/components_confirmation/","title":"Confirmation - JavaScript API","text":"

    The purpose of confirmation dialogs is to prevent misclicks and to inform the user of potential consequences of their action. A confirmation dialog should always ask a concise question that includes a reference to the object the action is performed upon.

    You can exclude extra information or form elements in confirmation dialogs, but these should be kept as compact as possible.

    "},{"location":"javascript/components_confirmation/#example","title":"Example","text":"
    const result = await confirmationFactory()\n.custom(\"Do you want a cookie?\")\n.withoutMessage();\nif (result) {\n// User has confirmed the dialog.\n}\n

    Confirmation dialogs are a special type that use the role=\"alertdialog\" attribute and will always include a cancel button. The dialog itself will be limited to a width of 500px, the title can wrap into multiple lines and there will be no \u201cX\u201d button to close the dialog.

    "},{"location":"javascript/components_confirmation/#when-to-use","title":"When to Use","text":"

    Over the past few years the term \u201cConfirmation Fatique\u201d has emerged that describes the issue of having too many confirmation dialogs even there is no real need for them. A confirmation dialog should only be displayed when the action requires further inputs, for example, a soft delete that requires a reason, or when the action is destructive.

    "},{"location":"javascript/components_confirmation/#proper-wording","title":"Proper Wording","text":"

    The confirmation question should hint the severity of the action, in particular whether or not it is destructive. Destructive actions are those that cannot be undone and either cause a permanent mutation or that cause data loss. All questions should be phrased in one or two ways depending on the action.

    Destructive action:

    Are you sure you want to delete \u201cExample Object\u201d? (German) Wollen Sie \u201eBeispiel-Objekt\u201c wirklich l\u00f6schen?

    All other actions:

    Do you want to move \u201cExample Object\u201d to the trash bin? (German) M\u00f6chten Sie \u201eBeispiel-Objekt\u201c in den Papierkorb verschieben?

    "},{"location":"javascript/components_confirmation/#available-presets","title":"Available Presets","text":"

    WoltLab Suite 6.0 currently ships with three presets for common confirmation dialogs.

    All three presets have an optional parameter for the title of the related object as part of the question asked to the user. It is strongly recommended to provide the title if it exists, otherwise it can be omitted and an indeterminate variant is used instead.

    "},{"location":"javascript/components_confirmation/#soft-delete","title":"Soft Delete","text":"

    Soft deleting objects with an optional input field for a reason:

    const askForReason = true;\nconst { result, reason } = await confirmationFactory().softDelete(\ntheObjectName,\naskForReason\n);\nif (result) {\nconsole.log(\n\"The user has requested a soft delete, the following reason was provided:\",\nreason\n);\n}\n

    The reason will always be a string, but with a length of zero if the result is false or if no reason was requested. You can simply omit the value if you do not use the reason.

    const askForReason = false;\nconst { result } = await confirmationFactory().softDelete(\ntheObjectName,\naskForReason\n);\nif (result) {\nconsole.log(\"The user has requested a soft delete.\");\n}\n
    "},{"location":"javascript/components_confirmation/#restore","title":"Restore","text":"

    "},{"location":"javascript/components_dialog/","title":"Dialogs - JavaScript API","text":"

    Modal dialogs are a powerful tool to draw the viewer\u2019s attention to an important message, question or form. Dialogs naturally interrupt the workflow and prevent the navigation to other sections by making other elements on the page inert.

    WoltLab Suite 6.0 ships with four different types of dialogs.

    "},{"location":"javascript/components_dialog/#quickstart","title":"Quickstart","text":"

    There are four different types of dialogs that each fulfill their own specialized role and that provide built-in features to make the development much easier. Please see the following list to make a quick decision of what kind of dialog you need.

    "},{"location":"javascript/components_dialog/#dialogs-without-controls","title":"Dialogs Without Controls","text":"

    Dialogs may contain just an explanation or extra information that should be presented to the viewer without requiring any further interaction. The dialog can be closed via the \u201cX\u201d button or by clicking the modal backdrop.

    const dialog = dialogFactory().fromHtml(\"<p>Hello World</p>\").withoutControls();\ndialog.show(\"Greetings from my dialog\");\n
    "},{"location":"javascript/components_dialog/#when-to-use","title":"When to Use","text":"

    The short answer is: Don\u2019t.

    Dialogs without controls are an anti-pattern because they only contain content that does not require the modal appearance of a dialog. More often than not dialogs are used for this kind of content because they are easy to use without thinking about better ways to present the content.

    If possible these dialogs should be avoided and the content is presented in a more suitable way, for example, as a flyout or by showing content on an existing or new page.

    "},{"location":"javascript/components_dialog/#alerts","title":"Alerts","text":"

    Alerts are designed to inform the user of something important that requires no further action by the user. Typical examples for alerts are error messages or warnings.

    An alert will only provide a single button to acknowledge the dialog and must not contain interactive content. The dialog itself will be limited to a width of 500px, the title can wrap into multiple lines and there will be no \u201cX\u201d button to close the dialog.

    const dialog = dialogFactory()\n.fromHtml(\"<p>ERROR: Something went wrong!</p>\")\n.asAlert();\ndialog.show(\"Server Error\");\n

    You can customize the label of the primary button to better explain what will happen next. This can be useful for alerts that will have a side-effect when closing the dialog, such as redirect to a different page.

    const dialog = dialogFactory()\n.fromHtml(\"<p>Something went wrong, we cannot find your shopping cart.</p>\")\n.asAlert({\nprimary: \"Back to the Store Page\",\n});\n\ndialog.addEventListener(\"primary\", () => {\nwindow.location.href = \"https://example.com/shop/\";\n});\n\ndialog.show(\"The shopping cart is missing\");\n

    The primary event is triggered both by clicking on the primary button and by clicks on the modal backdrop.

    "},{"location":"javascript/components_dialog/#when-to-use_1","title":"When to Use","text":"

    Alerts are a special type of dialog that use the role=\"alert\" attribute to signal its importance to assistive tools. Use alerts sparingly when there is no other way to communicate that something did not work as expected.

    Alerts should not be used for cases where you expect an error to happen. For example, a form control that expectes an input to fall within a restricted range should show an inline error message instead of raising an alert.

    "},{"location":"javascript/components_dialog/#confirmation","title":"Confirmation","text":"

    Confirmation dialogs are supported through a separate factory function that provides a set of presets as well as a generic API. Please see the separate documentation for confirmation dialogs to learn more.

    "},{"location":"javascript/components_dialog/#prompts","title":"Prompts","text":"

    The most common type of dialogs are prompts that are similar to confirmation dialogs, but without the restrictions and with a regular title. These dialogs can be used universally and provide a submit and cancel button by default.

    In addition they offer an \u201cextra\u201d button that is placed to the left of the default buttons are can be used to offer a single additional action. A possible use case for an \u201cextra\u201d button would be a dialog that includes an instance of the WYSIWYG editor, the extra button could be used to trigger a message preview.

    "},{"location":"javascript/general-usage/#the-history-of-the-legacy-api","title":"The History of the Legacy API","text":"

    The WoltLab Suite 3.0 introduced a new API based on AMD-Modules with ES5-JavaScript that was designed with high performance and visible dependencies in mind. This was a fundamental change in comparison to the legacy API that was build many years before while jQuery was still a thing and we had to deal with ancient browsers such as Internet Explorer 9 that felt short in both CSS and JavaScript capabilities.

    Fast forward a few years, the old API is still around and most important, it is actively being used by some components that have not been rewritten yet. This has been done to preserve the backwards-compatibility and to avoid the significant amount of work that it requires to rewrite a component. The components invoked on page initialization have all been rewritten to use the modern API, but some deferred objects that are invoked later during the page runtime may still use the old API.

    However, the legacy API is deprecated and you should not rely on it for new components at all. It slowly but steadily gets replaced up until a point where its last bits are finally removed from the code base.

    "},{"location":"javascript/general-usage/#embedding-javascript-inside-templates","title":"Embedding JavaScript inside Templates","text":"

    The <script>-tags are extracted and moved during template processing, eventually placing them at the very end of the body element while preserving their order of appearance.

    This behavior is controlled through the data-relocate=\"true\" attribute on the <script> which is mandatory for almost all scripts, mostly because their dependencies (such as jQuery) are moved to the bottom anyway.

    <script data-relocate=\"true\">\n$(function() {\n// Code that uses jQuery (Legacy API)\n});\n</script>\n\n<!-- or -->\n\n<script data-relocate=\"true\">\nrequire([\"Some\", \"Dependencies\"], function(Some, Dependencies) {\n// Modern API\n});\n</script>\n

    Your JavaScript files may change over time and you would want the users' browsers to always load and use the latest version of your files. This can be achieved by appending the special LAST_UPDATE_TIME constant to your file path. It contains the unix timestamp of the last time any package was installed, updated or removed and thus avoid outdated caches by relying on a unique value, without invalidating the cache more often that it needs to be.

    <script data-relocate=\"true\" src=\"{$__wcf->getPath('app')}js/App.js?t={@LAST_UPDATE_TIME}\"></script>\n

    For small scripts you can simply serve the full, non-minified version to the user at all times, the differences in size and execution speed are insignificant and are very unlikely to offer any benefits. They might even yield a worse performance, because you'll have to include them statically in the template, even if the code is never called.

    However, if you're including a minified build in your app or plugin, you should include a switch to load the uncompressed version in the debug mode, while serving the minified and optimized file to the average visitor. You should use the ENABLE_DEBUG_MODE constant to decide which version should be loaded.

    The \u201cAccelerated Guest View\u201d aims to decrease page size and to improve responsiveness by enabling a read-only mode for visitors. If you are providing a separate compiled build for this mode, you'll need to include yet another switch to serve the right version to the visitor.

    The legacy JavaScript API is the original code that was part of the 2.x series of WoltLab Suite, formerly known as WoltLab Community Framework. It has been superseded for the most part by the ES5/AMD-modules API introduced with WoltLab Suite 3.0.

    Some parts still exist to this day for backwards-compatibility and because some less important components have not been rewritten yet. The old API is still supported, but marked as deprecated and will continue to be replaced parts by part in future releases, up until their entire removal, including jQuery support.

This method is significantly more expensive for repeated requests and does not offer deriving modules from altering the behavior. It is strongly recommended to always use Ajax.api() for requests to the WSC API endpoint.

    The new JavaScript-API was introduced with WoltLab Suite 3.0 and was a major change in all regards. The previously used API heavily relied on larger JavaScript files that contained a lot of different components with hidden dependencies and suffered from extensive jQuery usage for historic reasons.

    Eventually a new API was designed that solves the issues with the legacy API by following a few basic principles: 1. Vanilla ES5-JavaScript. It allows us to achieve the best performance across all platforms, there is simply no reason to use jQuery today and the performance penalty on mobile devices is a real issue. 2. Strict usage of modules. Each component is placed in an own file and all dependencies are explicitly declared and injected at the top.Eventually we settled with AMD-style modules using require.js which offers both lazy loading and \"ahead of time\"-compilatio with r.js. 3. No jQuery-based components on page init. Nothing is more annoying than loading a page and then wait for JavaScript to modify the page before it becomes usable, forcing the user to sit and wait. Heavily optimized vanilla JavaScript components offered the speed we wanted. 4. Limited backwards-compatibility. The new API should make it easy to update existing components by providing similar interfaces, while still allowing legacy code to run side-by-side for best compatibility and to avoid rewritting everything from the start.

    "},{"location":"javascript/new-api_writing-a-module/#defining-a-module","title":"Defining a Module","text":"

    The default location for modules is js/ in the Core's app dir, but every app and plugin can register their own lookup path by providing the path using a template-listener on requirePaths@headIncludeJavaScript.

    For this example we'll assume the file is placed at js/WoltLabSuite/Core/Ui/Foo.js, the module name is therefore WoltLabSuite/Core/Ui/Foo, it is automatically derived from the file path and name.

    For further instructions on how to define and require modules head over to the RequireJS API.

    define([\"Ajax\", \"WoltLabSuite/Core/Ui/Bar\"], function(Ajax, UiBar) {\n\"use strict\";\n\nfunction Foo() { this.init(); }\nFoo.prototype = {\ninit: function() {\nelBySel(\".myButton\").addEventListener(WCF_CLICK_EVENT, this._click.bind(this));\n},\n\n_click: function(event) {\nevent.preventDefault();\n\nif (UiBar.isSnafucated()) {\nAjax.api(this);\n}\n},\n\n_ajaxSuccess: function(data) {\nconsole.log(\"Received response\", data);\n},\n\n_ajaxSetup: function() {\nreturn {\ndata: {\nactionName: \"makeSnafucated\",\nclassName: \"wcf\\\\data\\\\foo\\\\FooAction\"\n}\n};\n}\n}\n\nreturn Foo;\n});\n

    To consume the types of WoltLab Suite, you will need to install the @woltlab/wcf npm package using a git URL that refers to the appropriate branch of WoltLab/WCF.

    A full package.json that includes WoltLab Suite, TypeScript, eslint and Prettier could look like the following.

    package.json 
    {\n\"devDependencies\": {\n\"@typescript-eslint/eslint-plugin\": \"^5.51.0\",\n\"@typescript-eslint/parser\": \"^5.51.0\",\n\"eslint\": \"^8.33.0\",\n\"eslint-config-prettier\": \"^8.6.0\",\n\"prettier\": \"^2.8.4\",\n\"typescript\": \"^4.9.5\"\n},\n\"dependencies\": {\n\"@woltlab/d.ts\": \"https://github.com/WoltLab/d.ts.git#4040fc083245edeb2f8832d4613b9e76aa9c17a5\"\n}\n}\n

    After installing the types using npm, you will also need to configure tsconfig.json to take the types into account. To do so, you will need to add them to the compilerOptions.paths option. A complete tsconfig.json file that matches the configuration of WoltLab Suite could look like the following.

    tsconfig.json 
    {\n\"include\": [\n\"node_modules/@woltlab/d.ts/global.d.ts\",\n\"ts/**/*\"\n],\n\"compilerOptions\": {\n\"target\": \"ES2022\",\n\"module\": \"amd\",\n\"rootDir\": \"ts/\",\n\"outDir\": \"files/js/\",\n\"lib\": [\n\"DOM\",\n\"DOM.Iterable\",\n\"ES2022\"\n],\n\"strictNullChecks\": true,\n\"moduleResolution\": \"node\",\n\"esModuleInterop\": true,\n\"noImplicitThis\": true,\n\"strictBindCallApply\": true,\n\"baseUrl\": \".\",\n\"paths\": {\n\"*\": [\n\"node_modules/@woltlab/d.ts/*\"\n]\n},\n\"importHelpers\": true,\n\"newLine\": \"lf\"\n}\n}\n

    After this initial set-up, you would place your TypeScript source files into the ts/ folder of your project. The generated JavaScript target files will be placed into files/js/ and thus will be installed by the file PIP.

    To update the TypeScript types, the commit hash in package.json needs to be updated to an appropriate commit in the d.ts repository and npm install needs to be rerun.

    The new tiny builds are highly optimized variants of existing JavaScript files and modules, aiming for significant performance improvements for guests and search engines alike. This is accomplished by heavily restricting page interaction to read-only actions whenever possible, which in return removes the need to provide certain JavaScript modules in general.

    For example, disallowing guests to write any formatted messages will in return remove the need to provide the WYSIWYG editor at all. But it doesn't stop there, there are a lot of other modules that provide additional features for the editor, and by excluding the editor, we can also exclude these modules too.

    Long story short, the tiny mode guarantees that certain actions will never be carried out by guests or search engines, therefore some modules are not going to be needed by them ever.

This issue has been around for quite a long time and countless of implementations are relying on this false behavior, eventually forcing us to leave the value unchanged.

    This problem is solved by adding the new property realErrorMessage that exposes the message exactly as it was provided and now matches the value that would be displayed to users in traditional forms.

    "},{"location":"migration/wsc30/javascript/#example-code","title":"Example Code","text":"

    Forms embedded in dialogs often do not contain the HTML <form>-element and instead rely on JavaScript click- and key-handlers to emulate a <form>-like submit behavior. This has spawned a great amount of nearly identical implementations that all aim to handle the form submit through the Enter-key, still leaving some dialogs behind.

    WoltLab Suite 3.1 offers automatic form submit that is enabled through a set of specific conditions and data attributes:

    1. There must be a submit button that matches the selector .formSubmit > input[type=\"submit\"], .formSubmit > button[data-type=\"submit\"].
    2. The dialog object provided to UiDialog.open() implements the method _dialogSubmit().
    3. Input fields require the attribute data-dialog-submit-on-enter=\"true\" to be set, the type must be one of number, password, search, tel, text or url.

    Clicking on the submit button or pressing the Enter-key in any watched input field will start the submit process. This is done automatically and does not require a manual interaction in your code, therefore you should not bind any click listeners on the submit button yourself.

    Any input field with the required attribute set will be validated to contain a non-empty string after processing the value with String.prototype.trim(). An empty field will abort the submit process and display a visible error message next to the offending field.

    Displaying inline error messages on-the-fly required quite a few DOM operations that were quite simple but also super repetitive and thus error-prone when incorrectly copied over. The global helper function elInnerError() was added to provide a simple and consistent behavior of inline error messages.

    You can display an error message by invoking elInnerError(elementRef, \"Your Error Message\"), it will insert a new <small class=\"innerError\"> and sets the given message. If there is already an inner error present, then the message will be replaced instead.

    Hiding messages is done by setting the 2nd parameter to false or an empty string:

    The special values null and undefined are supported too, but their usage is discouraged, because they make it harder to understand the intention by reading the code:

    Updating the template is easy as the complete form is replace by a single line of code:

    acptemplates/personAdd.tpl 
    {include file='header' pageTitle='wcf.acp.person.'|concat:$action}\n\n<header class=\"contentHeader\">\n    <div class=\"contentHeaderTitle\">\n        <h1 class=\"contentTitle\">{lang}wcf.acp.person.{$action}{/lang}</h1>\n    </div>\n\n    <nav class=\"contentHeaderNavigation\">\n        <ul>\n            <li><a href=\"{link controller='PersonList'}{/link}\" class=\"button\"><span class=\"icon icon16 fa-list\"></span> <span>{lang}wcf.acp.menu.link.person.list{/lang}</span></a></li>\n\n{event name='contentHeaderNavigation'}\n        </ul>\n    </nav>\n</header>\n\n{@$form->getHtml()}\n\n{include file='footer'}\n

    PersonEditForm also becomes much simpler: only the edited Person object must be read:

    files/lib/acp/form/PersonEditForm.class.php 
    <?php\nnamespace wcf\\acp\\form;\nuse wcf\\data\\person\\Person;\nuse wcf\\system\\exception\\IllegalLinkException;\n\n/**\n * Shows the form to edit an existing person.\n * \n * @author  Matthias Schmidt\n * @copyright   2001-2019 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\Acp\\Form\n */\nclass PersonEditForm extends PersonAddForm {\n    /**\n     * @inheritDoc\n     */\n    public $activeMenuItem = 'wcf.acp.menu.link.person';\n\n    /**\n     * @inheritDoc\n     */\n    public function readParameters() {\n        parent::readParameters();\n\n        if (isset($_REQUEST['id'])) {\n            $this->formObject = new Person(intval($_REQUEST['id']));\n            if (!$this->formObject->personID) {\n                throw new IllegalLinkException();\n            }\n        }\n    }\n}\n

    Most of the work is done in PersonAddForm:

    files/lib/acp/form/PersonAddForm.class.php 
    <?php\nnamespace wcf\\acp\\form;\nuse wcf\\data\\person\\PersonAction;\nuse wcf\\form\\AbstractFormBuilderForm;\nuse wcf\\system\\form\\builder\\container\\FormContainer;\nuse wcf\\system\\form\\builder\\field\\TextFormField;\n\n/**\n * Shows the form to create a new person.\n * \n * @author  Matthias Schmidt\n * @copyright   2001-2019 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\Acp\\Form\n */\nclass PersonAddForm extends AbstractFormBuilderForm {\n    /**\n     * @inheritDoc\n     */\n    public $activeMenuItem = 'wcf.acp.menu.link.person.add';\n\n    /**\n     * @inheritDoc\n     */\n    public $formAction = 'create';\n\n    /**\n     * @inheritDoc\n     */\n    public $neededPermissions = ['admin.content.canManagePeople'];\n\n    /**\n     * @inheritDoc\n     */\n    public $objectActionClass = PersonAction::class;\n\n    /**\n     * @inheritDoc\n     */\n    protected function createForm() {\n        parent::createForm();\n\n        $dataContainer = FormContainer::create('data')\n            ->appendChildren([\n                TextFormField::create('firstName')\n                    ->label('wcf.person.firstName')\n                    ->required()\n                    ->maximumLength(255),\n\n                TextFormField::create('lastName')\n                    ->label('wcf.person.lastName')\n                    ->required()\n                    ->maximumLength(255)\n            ]);\n\n        $this->form->appendChild($dataContainer);\n    }\n}\n

    But, as you can see, the number of lines almost decreased by half. All changes are due to extending AbstractFormBuilderForm:

    "},{"location":"migration/wsc31/like/","title":"Migrating from WSC 3.1 - Like System","text":""},{"location":"migration/wsc31/like/#introduction","title":"Introduction","text":"

    With version 5.2 of WoltLab Suite Core the like system was completely replaced by the new reactions system. This makes it necessary to make some adjustments to existing code so that your plugin integrates completely into the new system. However, we have kept these adjustments as small as possible so that it is possible to use the reaction system with slight restrictions even without adjustments.

    "},{"location":"migration/wsc31/like/#limitations-if-no-adjustments-are-made-to-the-existing-code","title":"Limitations if no adjustments are made to the existing code","text":"

    If no adjustments are made to the existing code, the following functions are not available: * Notifications about reactions/likes * Recent Activity Events for reactions/likes

    Since there are no more likes with the new version, it makes no sense to send notifications about it. Instead of notifications about likes, notifications about reactions are now sent. However, this only changes the notification text and not the notification itself. To update the notification, we first add the interface \\wcf\\data\\reaction\\object\\IReactionObject to the \\wcf\\data\\like\\object\\ILikeObject object (e.g. in WoltLab Suite Forum we added the interface to the class \\wbb\\data\\post\\LikeablePost). After that the object is marked as \"compatible with WoltLab Suite Core 5.2\" and notifications about reactions are sent again.

    "},{"location":"migration/wsc31/like/#language-variables","title":"Language Variables","text":"

    Next, to display all reactions for the current notification in the notification text, we include the trait \\wcf\\system\\user\\notification\\event\\TReactionUserNotificationEvent in the user notification event class (typically named like *LikeUserNotificationEvent). These trait provides a new function that reads out and groups the reactions. The result of this function must now only be passed to the language variable. The name \"reactions\" is typically used as the variable name for the language variable.

    As a final step, we only need to change the language variables themselves. To ensure a consistent usability, the same formulations should be used as in the WoltLab Suite Core.

    To adjust entries in the Recent Activity, only three small steps are necessary. First we pass the concrete reaction to the language variable, so that we can use the reaction object there. To do this, we add the following variable to the text of the \\wcf\\system\\user\\activity\\event\\IUserActivityEvent object: $event->reactionType. Typically we name the variable reactionType. In the second step, we mark the event as compatible. Therefore we set the parameter supportsReactions in the objectType.xml to 1. So for example the entry looks like this:

    objectType.xml
    <type>\n<name>com.woltlab.example.likeableObject.recentActivityEvent</name>\n<definitionname>com.woltlab.wcf.user.recentActivityEvent</definitionname>\n<classname>wcf\\system\\user\\activity\\event\\LikeableObjectUserActivityEvent</classname>\n<supportsReactions>1</supportsReactions>\n</type>\n

    Finally we modify our language variable. To ensure a consistent usability, the same formulations should be used as in the WoltLab Suite Core.

    If comments send notifications, they must also be updated. The language variables are changed in the same way as described in the section Notifications / Language.

    So that these changes also work in older versions of WoltLab Suite Core, the used classes and traits were backported with WoltLab Suite Core 3.0.22 and WoltLab Suite Core 3.1.10.

    User content providers help the WoltLab Suite to find user generated content. They provide a class with which you can find content from a particular user and delete objects.

    "},{"location":"migration/wsc31/php/#php-class","title":"PHP Class","text":"

    First, we create the PHP class that provides our interface to provide the data. The class must implement interface wcf\\system\\user\\content\\provider\\IUserContentProvider in any case. Mostly we process data which is based on wcf\\data\\DatabaseObject. In this case, the WoltLab Suite provides an abstract class wcf\\system\\user\\content\\provider\\AbstractDatabaseUserContentProvider that can be used to automatically generates the standardized classes to generate the list and deletes objects via the DatabaseObjectAction. For example, if we would create a content provider for comments, the class would look like this:

    files/lib/system/user/content/provider/CommentUserContentProvider.class.php
    <?php\nnamespace wcf\\system\\user\\content\\provider;\nuse wcf\\data\\comment\\Comment;\n\n/**\n * User content provider for comments.\n *\n * @author  Joshua Ruesweg\n * @copyright   2001-2018 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\User\\Content\\Provider\n * @since   5.2\n */\nclass CommentUserContentProvider extends AbstractDatabaseUserContentProvider {\n    /**\n     * @inheritdoc\n     */\n    public static function getDatabaseObjectClass() {\n        return Comment::class;\n    }\n}\n
    "},{"location":"migration/wsc31/php/#object-type","title":"Object Type","text":"

    Now the appropriate object type must be created for the class. This object type must be from the definition com.woltlab.wcf.content.userContentProvider and include the previous created class as FQN in the parameter classname. Also the following parameters can be used in the object type:

Exceptions cannot be mapped using this compatibility layer, any catch blocks catching a specific Exception within the Leafo namespace will need to be adjusted.

    It is recommended by search engines to mark up links within user generated content using the rel=\"ugc\" attribute to indicate that they might be less trustworthy or spammy.

    WoltLab Suite 5.3 will automatically sets that attribute on external links during message output processing. Set the new HtmlOutputProcessor::$enableUgc property to false if the type of message is not user-generated content, but restricted to a set of trustworthy users. An example of such a type of message would be official news articles.

    If you manually generate links based off user input you need to specify the attribute yourself. The $isUgc attribute was added to StringUtil::getAnchorTag(string, string, bool, bool): string, allowing you to easily generate a correct anchor tag.

    If you need to specify additional HTML attributes for the anchor tag you can use the new StringUtil::getAnchorTagAttributes(string, bool): string method to generate the anchor attributes that are dependent on the target URL. Specifically the attributes returned are the class=\"externalURL\" attribute, the rel=\"\u2026\" attribute and the target=\"\u2026\" attribute.

    It was discovered that the code holds references to scaled image resources for an unnecessarily long time, taking up memory. This becomes especially apparent when multiple images are scaled within a loop, reusing the same variable name for consecutive images. Unless the destination variable is explicitely cleared before processing the next image up to two images will be stored in memory concurrently. This possibly causes the request to exceed the memory limit or ImageMagick's internal resource limits, even if sufficient resources would have been available to scale the current image.

    Starting with WoltLab Suite 5.3 it is recommended to clear image handles as early as possible. The usual pattern of creating a thumbnail for an existing image would then look like this:

    <?php\nforeach ([ 200, 500 ] as $size) {\n    $adapter = ImageHandler::getInstance()->getAdapter();\n    $adapter->loadFile($src);\n    $thumbnail = $adapter->createThumbnail(\n        $size,\n        $size,\n        true\n    );\n    $adapter->writeImage($thumbnail, $destination);\n    // New: Clear thumbnail as soon as possible to free up the memory.\n    $thumbnail = null;\n}\n

    WCF.Action.Delete and WCF.Action.Toggle were used for buttons to delete or enable/disable objects via JavaScript. In each template, WCF.Action.Delete or WCF.Action.Toggle instances had to be manually created for each object listing.

    With version 5.4 of WoltLab Suite, we have added a CSS selector-based global TypeScript module that only requires specific CSS classes to be added to the HTML structure for these buttons to work. Additionally, we have added a new {objectAction} template plugin, which generates these buttons reducing the amount of boilerplate template code.

    The required base HTML structure is as follows:

    1. A .jsObjectActionContainer element with a data-object-action-class-name attribute that contains the name of PHP class that executes the actions.
    2. .jsObjectActionObject elements within .jsObjectActionContainer that represent the objects for which actions can be executed. Each .jsObjectActionObject element must have a data-object-id attribute with the id of the object.
    3. .jsObjectAction elements within .jsObjectActionObject for each action with a data-object-action attribute with the name of the action. These elements can be generated with the {objectAction} template plugin for the delete and toggle action.

    Example:

    <table class=\"table jsObjectActionContainer\" {*\n    *}data-object-action-class-name=\"wcf\\data\\foo\\FooAction\">\n    <thead>\n        <tr>\n{* \u2026 *}\n        </tr>\n    </thead>\n\n    <tbody>\n{foreach from=$objects item=foo}\n            <tr class=\"jsObjectActionObject\" data-object-id=\"{$foo->getObjectID()}\">\n                <td class=\"columnIcon\">\n{objectAction action=\"toggle\" isDisabled=$foo->isDisabled}\n{objectAction action=\"delete\" objectTitle=$foo->getTitle()}\n{* \u2026 *}\n                </td>\n{* \u2026 *}\n            </tr>\n{/foreach}\n    </tbody>\n</table>\n

    Please refer to the documentation in ObjectActionFunctionTemplatePlugin for details and examples on how to use this template plugin.

    The relevant TypeScript module registering the event listeners on the object action buttons is Ui/Object/Action. When an action button is clicked, an AJAX request is sent using the PHP class name and action name. After the successful execution of the action, the page is either reloaded if the action button has a data-object-action-success=\"reload\" attribute or an event using the EventHandler module is fired using WoltLabSuite/Core/Ui/Object/Action as the identifier and the object action name. Ui/Object/Action/Delete and Ui/Object/Action/Toggle listen to these events and update the user interface depending on the execute action by removing the object or updating the toggle button, respectively.

    Converting from WCF.Action.* to the new approach requires minimal changes per template, as shown in the relevant pull request #4080.

As a TypeScript-based replacement for WCF.Table.EmptyTableHandler that is only initialized once globally, WoltLabSuite/Core/Ui/Empty was added. To use this new module, you only have to add the CSS class jsReloadPageWhenEmpty to the relevant HTML element. Once this HTML element no longer has child elements, the page is reloaded. To also cover scenarios in which there are fixed child elements that should not be considered when determining if there are no child elements, the data-reload-page-when-empty=\"ignore\" can be set for these elements.

With WoltLab Suite 5.4, we have added a general API that manages such rate limiting. Leveraging this API is easily done.

    1. Register an object type for the definition com.woltlab.wcf.floodControl: com.example.foo.myContent.

    3. To check the last time when the active user created content of the relevant type, use 

      FloodControl::getInstance()->getLastTime('com.example.foo.myContent');\n
      If you want to limit the number of content items created within a certain period of time, for example within one day, use 
      $data = FloodControl::getInstance()->countContent('com.example.foo.myContent', new \\DateInterval('P1D'));\n// number of content items created within the last day\n$count = $data['count'];\n// timestamp when the earliest content item was created within the last day\n$earliestTime = $data['earliestTime'];\n
      The method also returns earliestTime so that you can tell the user in the error message when they are able again to create new content of the relevant type.

      Flood control entries are only stored for 31 days and older entries are cleaned up daily.

Pass either UserIgnore::TYPE_BLOCK_DIRECT_CONTACT or UserIgnore::TYPE_HIDE_MESSAGES depending on whether the check refers to a non-directed usage or content.

    See WoltLab/WCF#4064 and WoltLab/WCF#3981 for details.

    WoltLab Suite 5.4 includes a completely refactored session handling. As long as you only interact with sessions via WCF::getSession(), especially when you perform read-only accesses, you should not notice any breaking changes.

    You might appreciate some of the new session methods if you process security sensitive data.

    "},{"location":"migration/wsc53/session/#summary-and-concepts","title":"Summary and Concepts","text":"

    Most of the changes revolve around the removal of the legacy persistent login functionality and the assumption that every user has a single session only. Both aspects are related to each other.

    "},{"location":"migration/wsc53/session/#legacy-persistent-login","title":"Legacy Persistent Login","text":"

    The legacy persistent login was rather an automated login. Upon bootstrapping a session, it was checked whether the user had a cookie pair storing the user\u2019s userID and (a single BCrypt hash of) the user\u2019s password. If such a cookie pair exists and the BCrypt hash within the cookie matches the user\u2019s password hash when hashed again, the session would immediately changeUser() to the respective user.

    This legacy persistent login was completely removed. Instead, any sessions that belong to an authenticated user will automatically be long-lived. These long-lived sessions expire no sooner than 14 days after the last activity, ensuring that the user continously stays logged in, provided that they visit the page at least once per fortnight.

    "},{"location":"migration/wsc53/session/#multiple-sessions","title":"Multiple Sessions","text":"

    To allow for a proper separation of these long-lived user sessions, WoltLab Suite now allows for multiple sessions per user. These sessions are completely unrelated to each other. Specifically, they do not share session variables and they expire independently.

    As the existing wcf1_session table is also used for the online lists and location tracking, it will be maintained on a best effort basis. It no longer stores any private session data.

    The actual sessions storing security sensitive information are in an unrelated location. They must only be accessed via the PHP API exposed by the SessionHandler.

    "},{"location":"migration/wsc53/session/#merged-acp-and-frontend-sessions","title":"Merged ACP and Frontend Sessions","text":"

    WoltLab Suite 5.4 shares a single session across both the frontend, as well as the ACP. When a user logs in to the frontend, they will also be logged into the ACP and vice versa.

    Actual access to the ACP is controlled via the new reauthentication mechanism.

    The session variable store is scoped: Session variables set within the frontend are not available within the ACP and vice versa.

    The wcf1_session table will no longer be used for session storage. Instead, it is maintained for compatibility with existing online lists.

    The actual session storage is considered an implementation detail and you must not directly interact with the session tables. Future versions might support alternative session backends, such as Redis.

    Do not interact directly with the session database tables but only via the SessionHandler class!

    "},{"location":"migration/wsc53/session/#reauthentication","title":"Reauthentication","text":"

    For security sensitive processing, you might want to ensure that the account owner is actually present instead of a third party accessing a session that was accidentally left logged in.

    WoltLab Suite 5.4 ships with a generic reauthentication framework. To request reauthentication within your controller you need to:

    1. Use the wcf\\system\\user\\authentication\\TReauthenticationCheck trait.
    2. Call: 
      $this->requestReauthentication(LinkHandler::getInstance()->getControllerLink(static::class, [\n /* additional parameters */\n]));\n

    requestReauthentication() will check if the user has recently authenticated themselves. If they did, the request proceeds as usual. Otherwise, they will be asked to reauthenticate themselves. After the successful authentication, they will be redirected to the URL that was passed as the first parameter (the current controller within the example).

    Details can be found in WoltLab/WCF#3775.

    "},{"location":"migration/wsc53/session/#multi-factor-authentication","title":"Multi-factor Authentication","text":"

    To implement multi-factor authentication securely, WoltLab Suite 5.4 implements the concept of a \u201cpending user change\u201d. The user will not be logged in (i.e. WCF::getUser()->userID returns null) until they authenticate themselves with their second factor.

    Requesting multi-factor authentication is done on an opt-in basis for compatibility reasons. If you perform authentication yourself and do not trust the authentication source to perform multi-factor authentication itself, you will need to adjust your logic to request multi-factor authentication from WoltLab Suite:

    Previously:

    WCF::getSession()->changeUser($targetUser);\n

    Now:

    $isPending = WCF::getSession()->changeUserAfterMultifactorAuthentication($targetUser);\nif ($isPending) {\n    // Redirect to the authentication form. The user will not be logged in.\n    // Note: Do not use `getControllerLink` to support both the frontend as well as the ACP.\n    HeaderUtil::redirect(LinkHandler::getInstance()->getLink('MultifactorAuthentication', [\n        'url' => /* Return To */,\n    ]));\n    exit;\n}\n// Proceed as usual. The user will be logged in.\n
    "},{"location":"migration/wsc53/session/#adding-multi-factor-methods","title":"Adding Multi-factor Methods","text":"

    Adding your own multi-factor method requires the implementation of a single object type:

    objectType.xml
    <type>\n<name>com.example.multifactor.foobar</name>\n<definitionname>com.woltlab.wcf.multifactor</definitionname>\n<icon><!-- Font Awesome 4 Icon Name goes here. --></icon>\n<priority><!-- Determines the sort order, higher priority will be preferred for authentication. --></priority>\n<classname>wcf\\system\\user\\multifactor\\FoobarMultifactorMethod</classname>\n</type>\n

    The given classname must implement the IMultifactorMethod interface.

    As a self-contained example, you can find the initial implementation of the email multi-factor method in WoltLab/WCF#3729. Please check the version history of the PHP class to make sure you do not miss important changes that were added later.

    Multi-factor authentication is security sensitive. Make sure to carefully read the remarks in IMultifactorMethod for possible issues. Also make sure to carefully test your implementation against all sorts of incorrect input and consider attack vectors such as race conditions. It is strongly recommended to generously check the current state by leveraging assertions and exceptions.

    "},{"location":"migration/wsc53/session/#enforcing-multi-factor-authentication","title":"Enforcing Multi-factor Authentication","text":"

    To enforce Multi-factor Authentication within your controller you need to:

    1. Use the wcf\\system\\user\\multifactor\\TMultifactorRequirementEnforcer trait.
    2. Call: $this->enforceMultifactorAuthentication();

    enforceMultifactorAuthentication() will check if the user is in a group that requires multi-factor authentication, but does not yet have multi-factor authentication enabled. If they did, the request proceeds as usual. Otherwise, a NamedUserException is thrown.

    Historically, events were tightly coupled with a single class, with the event object being an object of this class, expecting the event listener to consume public properties and method of the event object. The $parameters array was introduced due to limitations of this pattern, avoiding moving all the values that might be of interest to the event listener into the state of the object. Events were still tightly coupled with the class that fired the event and using the opaque parameters array prevented IDEs from assisting with autocompletion and typing.

    WoltLab Suite 5.5 introduces the concept of dedicated, reusable event classes. Any newly introduced event will receive a dedicated class, implementing the wcf\\system\\event\\IEvent interface. These event classes may be fired from multiple locations, making them reusable to convey that a conceptual action happened, instead of a specific class doing something. An example for using the new event system could be a user logging in: Instead of listening on a the login form being submitted and the Facebook login action successfully running, an event UserLoggedIn might be fired whenever a user logs in, no matter how the login is performed.

    Additionally, these dedicated event classes will benefit from full IDE support. All the relevant values may be stored as real properties on the event object.

    Event classes should not have an Event suffix and should be stored in an event namespace in a matching location. Thus, the UserLoggedIn example might have a FQCN of \\wcf\\system\\user\\authentication\\event\\UserLoggedIn.

    Event listeners for events implementing IEvent need to follow PSR-14, i.e. they need to be callable. In practice, this means that the event listener class needs to implement __invoke(). No interface has to be implemented in this case.

    Previously:

    $parameters = [\n    'value' => \\random_int(1, 1024),\n];\n\nEventHandler::getInstance()->fireAction($this, 'valueAvailable', $parameters);\n

    WoltLab Suite 5.5 changes the factory classes for common configurations of database columns within the PHP-based DDL API to contain a private constructor, preventing object creation.

    This change affects the following classes:

    The static create() method never returned an object of the factory class, but instead in object of the base type (e.g. IntDatabaseTableColumn for NotNullInt10DatabaseTableColumn). Constructing an object of these factory classes is considered a bug, as the class name implies a specific column configuration, that might or might not hold if the object is modified afterwards.

    See WoltLab/WCF#4564 for details.

    WoltLab Suite 5.5 adds the IDefaultValueDatabaseTableColumn interface which is used to check whether specifying a default value is legal. For backwards compatibility this interface is implemented by AbstractDatabaseTableColumn. You should explicitly add this interface to custom table column type classes to avoid breakage if the interface is removed from AbstractDatabaseTableColumn in a future version. Likewise you should explicitly check for the interface before attempting to access the methods related to the default value of a column.

    In the past dialogs have been used for all kinds of purposes, for example, to provide more details. Dialogs make it incredibly easy to add extra information or forms to an existing page without giving much thought: A simple button is all that it takes to show a dialog.

    This has lead to an abundance of dialogs that have been used in a lot of places where dialogs are not the right choice, something we are guilty of in a lot of cases. A lot of research has gone into the accessibility of dialogs and the general recommendations towards their usage and the behavior.

    One big issue of dialogs have been their inconsistent appearance in terms of form buttons and their (lack of) keyboard support for input fields. WoltLab Suite 6.0 provides a completely redesigned API that strives to make the process of creating dialogs much easier and features a consistent keyboard support out of the box.

    "},{"location":"migration/wsc55/dialogs/#conceptual-changes","title":"Conceptual Changes","text":"

    Dialogs are a powerful tool, but as will all things, it is easy to go overboard and eventually one starts using dialogs out of convenience rather than necessity. In general dialogs should only be used when you need to provide information out of flow, for example, for urgent error messages.

    A common misuse that we are guilty of aswell is the use of dialogs to present content. Dialogs completely interrupt whatever the user is doing and can sometimes even hide contextual relevant content on the page. It is best to embed information into regular pages and either use deep links to refer to them or make use of flyovers to present the content in place.

    Another important change is the handling of form inputs. Previously it was required to manually craft the form submit buttons, handle button clicks and implement a proper validation. The new API provides the \u201cprompt\u201d type which implements all this for you and exposing JavaScript events to validate, submit and cancel the dialog.

    Last but not least there have been updates to the visual appearance of dialogs. The new dialogs mimic the appearance on modern desktop operating systems as well as smartphones by aligning the buttons to the bottom right. In addition the order of buttons has been changed to always show the primary button on the rightmost position. These changes were made in an effort to make it easier for users to adopt an already well known control concept and to improve the overall accessibility.

    This is the most awkward feature of the legacy dialog API: Poorly documented and cumbersome to use. Implementing it required a dedicated form submit button and the keyboard interaction required the data-dialog-submit-on-enter=\"true\" attribute to be set on all input elements that should submit the form through Enter.

    The new dialog API takes advantage of the form[method=\"dialog\"] functionality which behaves similar to regular forms but will signal the form submit to the surrounding dialog. As a developer you only need to listen for the validate and the primary event to implement your logic.

    const dialog = dialogFactory()\n.fromId(\"myComplexDialogWithFormInputs\")\n.asPrompt();\n\ndialog.addEventListener(\"validate\", (event) => {\n// Validate the form inputs in `dialog.content`.\n\nif (validationHasFailed) {\nevent.preventDefault();\n}\n});\n\ndialog.addEventListener(\"primary\", () => {\n// The dialog has been successfully validated\n// and was submitted by the user.\n// You can access form inputs through `dialog.content`.\n});\n

    Both the old and the new API support the use of existing elements to create dialogs. It is recommended to use <template> in this case which will never be rendered and has a well-defined role.

    Dialogs have historically been using the same HTML markup that regular pages do, including but not limited to the use of sections. For dialogs that use only a single container it is recommend to drop the section entirely.

    If your dialog contain multiple sections it is recommended to skip the title of the first section.

    There is no universal pattern that fits every case, because dialogs vary greatly between each other and the required functionality causes the actual implementation to be different.

    As an example we have migrated the dialog to create a new box to use the new API. It uses a prompt dialog that automagically adds form controls and fires an event once the user submits the dialog. You can find the commit 3a9210f229f6a2cf5e800c2c4536c9774d02fc86 on GitHub.

    The changes can be summed up as follows:

    1. Use a <template> element for the dialog content.
    2. Remove the .formSubmit section from the HTML.
    3. Unwrap the contents by stripping the .section.
    4. Create and store the reference to the dialog in a property for later re-use.

    WoltLab Suite 6.0 introduces Font Awesome 6.0 which is a major upgrade over the previously used Font Awesome 4.7 icon library. The new version features not only many hundreds of new icons but also focused a lot more on icon consistency, namely the proper alignment of icons within the grid.

    The previous implementation of Font Awesome 4 included shims for Font Awesome 3 that was used before, the most notable one being the .icon notation instead of .fa as seen in Font Awesome 4 and later. In addition, Font Awesome 5 introduced the concept of different font weights to separate icons which was further extended in Font Awesome 6.

    In WoltLab Suite 6.0 we have made the decision to make a clean cut and drop support for the Font Awesome 3 shim as well as a Font Awesome 4 shim in order to dramatically reduce the CSS size and to clean up the implementation. Brand icons had been moved to a separate font in Font Awesome 5, but since more and more fonts are being added we have stepped back from relying on that font. We have instead made the decision to embed brand icons using inline SVGs which are much more efficient when you only need a handful of brand icons instead of loading a 100kB+ font just for a few icons.

    "},{"location":"migration/wsc55/icons/#misuse-of-icons-as-buttons","title":"Misuse of Icons as Buttons","text":"

    One pattern that could be found every here and then was the use of icons as buttons. Using icons in buttons is fine, as long as there is a readable title and that they are properly marked as buttons.

    A common misuse looks like this:

    <span class=\"icon icon16 fa-times pointer jsMyDeleteButton\" data-some-object-id=\"123\"></span>\n

    This example has a few problems, for starters it is not marked as a button which would require both role=\"button\" and tabindex=\"0\" to be recognized as such. Additionally there is no title which leaves users clueless about what the option does, especially visually impaired users are possibly unable to identify the icon.

    WoltLab Suite 6.0 addresses this issue by removing all default styling from <button> elements, making them the ideal choice for button type elements.

    <button class=\"jsMyDeleteButton\" data-some-object-id=\"123\" title=\"descriptive title here\">{icon name='xmark'}</button>\n

    Historically the application boot in WCF\u2019s constructor performed processing based on fundamentally request-specific values, such as the accessed URL, the request body, or cookies. This is problematic, because this makes the boot dependent on the HTTP environment which may not be be available, e.g. when using the CLI interface for maintenance jobs. The latter needs to emulate certain aspects of the HTTP environment for the boot to succeed. Furthermore one of the goals of the introduction of PSR-7/PSR-15-based request processing that was started in WoltLab Suite 5.5 is the removal of implicit global state in favor of explicitly provided values by means of a ServerRequestInterface and thus to achieve a cleaner architecture.

    To achieve a clean separation this type of request-specific logic will incrementally be moved out of the application boot in WCF\u2019s constructor and into the request processing stack that is launched by RequestHandler, e.g. by running appropriate PSR-15 middleware.

    An example of this type of request-specific logic that was previously happening during application boot is the check that verifies whether a user is banned and denies access otherwise. This check is based on a request-specific value, namely the user\u2019s session which in turn is based on a provided (HTTP) cookie. It is now moved into the CheckUserBan middleware.

    This move implies that custom scripts that include WoltLab Suite Core\u2019s global.php, without also invoking RequestHandler will no longer be able to rely on this type of access control having happened and will need to implement it themselves, e.g. by manually running the appropriate middlewares.

    Notably the following checks have been moved into a middleware:

    The initialization of the session itself and dependent subsystems (e.g. the user object and thus the current language) is still running during application boot for now. However it is planned to also move the session initialization into the middleware in a future version and then providing access to the session by adding an attribute on the ServerRequestInterface, instead of querying the session via WCF::getSession(). As such you should begin to stop relying on the session and user outside of RequestHandler\u2019s middleware stack and should also avoid calling WCF::getUser() and WCF::getSession() outside of a controller, instead adding a User parameter to your methods to allow an appropriate user to be passed from the outside.

    An example of a method that implicitly relies on these global values is the VisitTracker's trackObjectVisit() method. It only takes the object type, object ID and timestamp as the parameter and will determine the userID by itself. The trackObjectVisitByUserIDs() method on the other hand does not rely on global values. Instead the relevant user IDs need to be passed explicitly from the controller as parameters, thus making the information the method works with explicit. This also makes the method reusable for use cases where an object should be marked as visited for a user other than the active user, without needing to temporarily switch the active user in the session.

    The same is true for \u201cpermission checking\u201d methods on DatabaseObjects. Instead of having a $myObject->canView() method that uses WCF::getSession() or WCF::getUser() internally, the user should explicitly be passed to the method as a parameter, allowing for permission checks to happen in a different context, for example send sending notification emails.

    Likewise event listeners should not access these request-specific values at all, because they are unable to know whether the event was fired based on these request-specific values or whether some programmatic action fired the event for another arbitrary user. Instead they must retrieve the appropriate information from the event data only.

    "},{"location":"migration/wsc55/php/#bootstrap-scripts","title":"Bootstrap Scripts","text":"

    WoltLab Suite 6.0 adds package-specific bootstrap scripts allowing a package to execute logic during the application boot to prepare the environment before the request is passed through the middleware pipeline into the controller in RequestHandler.

    Bootstrap scripts are stored in the lib/bootstrap/ directory of WoltLab Suite Core with the package identifier as the file name. They do not need to be registered explicitly, as one future goal of the bootstrap scripts is reducing the amount of system state that needs to be stored within the database. Instead WoltLab Suite Core will automatically create a bootstrap loader that includes all installed bootstrap scripts as part of the package installation and uninstallation process.

    Bootstrap scripts will be loaded and the bootstrap functions will executed based on a topological sorting of all installed packages. A package can rely on all bootstrap scripts of its dependencies being loaded before its own bootstrap script is loaded. It can also rely on all bootstrap functions of its dependencies having executed before its own bootstrap functions is executed. However it cannot rely on any specific loading and execution order of non-dependencies.

    As hinted at in the previous paragraph, executing the bootstrap scripts happens in two phases:

    1. All bootstrap scripts will be include()d in topological order. The script is expected to return a Closure that is executed in phase 2.
    2. Once all bootstrap scripts have been included, the returned Closures will be executed in the same order the bootstrap scripts were loaded.
    files/lib/bootstrap/com.example.foo.php
    <?php\n\n// Phase (1).\n\nreturn static function (): void {\n    // Phase (2).\n};\n

    For the vast majority of packages it is expected that the phase (1) bootstrapping is not used, except to return the Closure. Instead the logic should reside in the Closures body that is executed in phase (2).

    As previously mentioned in the Application Boot section, WoltLab Suite 6.0 improves support for PSR-7/PSR-15-based request processing that was initially announced with WoltLab Suite 5.5.

    WoltLab Suite 5.5 added support for returning a PSR-7 ResponseInterface from a controller and recommended to migrate existing controllers based on AbstractAction to make use of RedirectResponse and JsonResponse instead of using HeaderUtil::redirect() or manually emitting JSON with appropriate headers. Processing the request values still used PHP\u2019s superglobals (specifically $_GET and $_POST).

    WoltLab Suite 6.0 adds support for controllers based on PSR-15\u2019s RequestHandlerInterface, supporting request processing based on a provided PSR-7 ServerRequestInterface object.

    "},{"location":"migration/wsc55/php/#recommended-changes-for-woltlab-suite-60","title":"Recommended changes for WoltLab Suite 6.0","text":"

    It is recommended to use RequestHandlerInterface-based controllers whenever an AbstractAction would previously be used. Furthermore any AJAX-based logic that would previously rely on AJAXProxyAction combined with a method in an AbstractDatabaseObjectAction should also be implemented using a dedicated RequestHandlerInterface-based controller. Both AbstractAction and AJAXProxyAction-based AJAX requests should be considered soft-deprecated going forward.

    When creating a RequestHandlerInterface-based controller, care should be taken to ensure no mutable state is stored in object properties of the controller itself. The state of the controller object must be identical before, during and after a request was processed. Any required values must be passed explicitly by means of method parameters and return values. Likewise any functionality called by the controller\u2019s handle() method should not rely on implicit global values, such as WCF::getUser(), as was explained in the previous section about request-specific logic.

    The recommended pattern for a RequestHandlerInterface-based controller looks as follows:

    files/lib/action/MyFancyAction.class.php
    <?php\n\nnamespace wcf\\action;\n\nuse Laminas\\Diactoros\\Response;\nuse Psr\\Http\\Message\\ServerRequestInterface;\nuse Psr\\Http\\Message\\ResponseInterface;\nuse Psr\\Http\\Server\\RequestHandlerInterface;\n\nfinal class MyFancyAction implements RequestHandlerInterface\n{\n    public function __construct()\n    {\n        /* 0. Explicitly register services used by the controller, to\n         *    make dependencies explicit and to avoid accidentally using\n         *    global state outside of a controller.\n         */\n    }\n\n    public function handle(ServerRequestInterface $request): ResponseInterface\n    {\n        /* 1. Perform permission checks and input validation. */\n\n        /* 2. Perform the action. The action must not rely on global state,\n         *    but instead only on explicitly passed values. It should assume\n         *    that permissions have already been validated by the controller,\n         *    allowing it to be reusable programmatically.\n         */\n\n        /* 3. Perform post processing. */\n\n        /* 4. Prepare the response, e.g. by querying an updated object from\n         *    the database.\n         */\n\n        /* 5. Send the response. */\n        return new Response();\n    }\n}\n

    It is recommended to leverage Valinor for structural validation of input values if using the FormBuilder is not a good fit, specifically for any values that are provided implicitly and are expected to be correct. WoltLab Suite includes a middleware that will automatically convert unhandled MappingErrors into a response with status HTTP 400 Bad Request.

    XSRF validation will implicitly be performed for any request that uses a HTTP verb other than GET. Likewise any requests with a JSON body will automatically be decoded by a middleware and stored as the ServerRequestInterface\u2019s parsed body.

    The Psr15DialogForm class combined with the usingFormBuilder() method of dialogFactory() provides a \u201cbatteries-included\u201d solution to create a AJAX- and FormBuilder-based RequestHandlerInterface-based controller.

    Within the JavaScript code the endpoint is queried using:

    const { ok, result } = await dialogFactory()\n.usingFormBuilder()\n.fromEndpoint(url);\n

    The returned Promise will resolve when the dialog is closed, either by successfully submitting the form or by manually closing it and thus aborting the process. If the form was submitted successfully ok will be true and result will contain the controller\u2019s response. If the dialog was closed without successfully submitting the form, ok will be false and result will be set to undefined.

    Within the PHP code, the form may be created as usual, but use Psr15DialogForm as the form document. The controller must return $dialogForm->toJsonResponse() for GET requests and validate the ServerRequestInterface using $dialogForm->validateRequest($request) for POST requests. The latter will return a ResponseInterface to be returned if the validation fails, otherwise null is returned. If validation succeeded, the controller must perform the resulting action and return a JsonResponse with the result key:

    if ($request->getMethod() === 'GET') {\n    return $dialogForm->toResponse();\n} elseif ($request->getMethod() === 'POST') {\n    $response = $dialogForm->validateRequest($request);\n    if ($response !== null) {\n        return $response;\n    }\n\n    $data = $dialogForm->getData();\n\n    // Use $data.\n\n    return new JsonResponse([\n        'result' => [\n            'some' => 'value',\n        ],\n    ]);\n} else {\n    // The used method is validated by a middleware.

    WoltLab Suite 6.0 increases the System Requirements to require PHP\u2019s intl extension to be installed and enabled, allowing you to rely on the functionality provided by it to better match the rules and conventions of the different languages and regions of the world.

    One example would be the formatting of numbers. WoltLab Suite included a feature to group digits within large numbers since early versions using the StringUtil::addThousandsSeparator() method. While this method was able to account for some language-specific differences, e.g. by selecting an appropriate separator character based on a phrase, it failed to account for all the differences in number formatting across countries and cultures.

    As an example, English as written in the United States of America uses commas to create groups of three digits within large numbers: 123,456,789. English as written in India on the other hand also uses commas, but digits are not grouped into groups of three. Instead the right-most three digits form a group and then another comma is added every two digits: 12,34,56,789.

    Another example would be German as used within Germany and Switzerland. While both countries use groups of three, the separator character differs. Germany uses a dot (123.456.789), whereas Switzerland uses an apostrophe (123\u2019456\u2019789). The correct choice of separator could already be configured using the afore-mentioned phrase, but this is both inconvenient and fails to account for other differences between the two countries. It also made it hard to keep the behavior up to date when rules change.

    PHP\u2019s intl extension on the other hand builds on the official Unicode rules, by relying on the ICU library published by the Unicode consortium. As such it is aware of the rules of all relevant languages and regions of the world and it is already kept up to date by the operating system\u2019s package manager.

    For the four example regions (en_US, en_IN, de_DE, de_CH) intl\u2019s NumberFormatter class will format the number 123456789 as follows, correctly implementing the rules:

    php > var_dump((new NumberFormatter('en_US', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(11) \"123,456,789\"\nphp > var_dump((new NumberFormatter('en_IN', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(12) \"12,34,56,789\"\nphp > var_dump((new NumberFormatter('de_DE', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(11) \"123.456.789\"\nphp > var_dump((new NumberFormatter('de_CH', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(15) \"123\u2019456\u2019789\"\n

    WoltLab Suite\u2019s StringUtil::formatNumeric() method is updated to leverage the NumberFormatter internally. However your package might have special requirements regarding formatting, for example when formatting currencies where the position of the currency symbol differs across languages. In those cases your package should manually create an appropriately configured class from Intl\u2019s feature set. The correct locale can be queried by the new Language::getLocale() method.

    Another use case that showcases the Language::getLocale() method might be localizing a country name using locale_get_display_region():

    php > var_dump(\\wcf\\system\\WCF::getLanguage()->getLocale());\nstring(5) \"en_US\"\nphp > var_dump(locale_get_display_region('_DE', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(7) \"Germany\"\nphp > var_dump(locale_get_display_region('_US', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(13) \"United States\"\nphp > var_dump(locale_get_display_region('_IN', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(5) \"India\"\nphp > var_dump(locale_get_display_region('_BR', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(6) \"Brazil\"\n

    PHP 8.2 adds native support for redacting parameters holding sensitive information in stack traces. Parameters with the #[\\SensitiveParameter] attribute will show a placeholder value within the stack trace and the error log.

    WoltLab Suite\u2019s exception handler contains logic to manually apply the sanitization for PHP versions before 8.2.

    It is strongly recommended to add this attribute to all parameters holding sensitive information. Examples for sensitive parameters include passwords/passphrases, access tokens, plaintext values to be encrypted, or private keys.

    As attributes are fully backwards and forwards compatible it is possible to apply the attribute to packages targeting older WoltLab Suite or PHP versions without causing errors.

    Example:

    function checkPassword(\n    #[\\SensitiveParameter]\n    $password,\n): bool {\n    // \u2026\n}\n

    WoltLab Suite featured a strict allow-list for template modifiers within the enterprise mode since 5.2. This allow-list has proved to be a reliable solution against malicious templates. To improve security and to reduce the number of differences between enterprise mode and non-enterprise mode the allow-list will always be enabled going forward.

    It is strongly recommended to keep the template logic as simple as possible by moving the heavy lifting into regular PHP code, reducing the number of (specialized) modifiers that need to be applied.

    While the sql package installation plugin supports adding and removing tables, columns, and indices, it is not able to handle cases where the added table, column, or index already exist. We have added a new PHP-based API to manipulate the database scheme which can be used in combination with the database package installation plugin that skips parts that already exist:

    return [\n    // list of `DatabaseTable` objects\n];\n

    All of the relevant components can be found in the wcf\\system\\database\\table namespace.

    "},{"location":"package/database-php-api/#database-tables","title":"Database Tables","text":"

    There are two classes representing database tables: DatabaseTable and PartialDatabaseTable. If a new table should be created, use DatabaseTable. In all other cases, PartialDatabaseTable should be used as it provides an additional save-guard against accidentally creating a new table by having a typo in the table name: If the tables does not already exist, a table represented by PartialDatabaseTable will cause an exception (while a DatabaseTable table will simply be created).

    To create a table, a DatabaseTable object with the table's name as to be created and table's columns, foreign keys and indices have to be specified:

    DatabaseTable::create('foo1_bar')\n    ->columns([\n        // columns\n    ])\n    ->foreignKeys([\n        // foreign keys\n    ])\n    ->indices([\n        // indices\n    ])\n

    To update a table, the same code as above can be used, except for PartialDatabaseTable being used instead of DatabaseTable.

    To drop a table, only the drop() method has to be called:

    PartialDatabaseTable::create('foo1_bar')\n    ->drop()\n
    "},{"location":"package/database-php-api/#columns","title":"Columns","text":"

    To represent a column of a database table, you have to create an instance of the relevant column class found in the wcf\\system\\database\\table\\column namespace. Such instances are created similarly to database table objects using the create() factory method and passing the column name as the parameter.

    Every column type supports the following methods:

    Depending on the specific column class implementing additional interfaces, the following methods are also available:

    Additionally, there are some additionally classes of commonly used columns with specific properties:

    Examples:

    DefaultFalseBooleanDatabaseTableColumn::create('isDisabled')\n\nNotNullInt10DatabaseTableColumn::create('fooTypeID')\n\nSmallintDatabaseTableColumn::create('bar')\n    ->length(5)\n    ->notNull()\n

    DatabaseTableForeignKey::create()\n    ->columns(['fooID'])\n    ->referencedTable('wcf1_foo')\n    ->referencedColumns(['fooID'])\n    ->onDelete('CASCADE')\n

    The supported actions for onDelete() and onUpdate() are CASCADE, NO ACTION, and SET NULL. To drop a foreign key, all of the relevant data to create the foreign key has to be present and the drop() method has to be called.

    DatabaseTableForeignKey::create() also supports the foreign key name as a parameter. If it is not present, DatabaseTable::foreignKeys() will automatically set one based on the foreign key's data.

    "},{"location":"package/database-php-api/#indices","title":"Indices","text":"

    Indices are represented by DatabaseTableIndex objects: 

    DatabaseTableIndex::create('fooID')\n    ->type(DatabaseTableIndex::UNIQUE_TYPE)\n    ->columns(['fooID'])\n

    There are four different types: DatabaseTableIndex::DEFAULT_TYPE (default), DatabaseTableIndex::PRIMARY_TYPE, DatabaseTableIndex::UNIQUE_TYPE, and DatabaseTableIndex::FULLTEXT_TYPE. For primary keys, there is also the DatabaseTablePrimaryIndex class which automatically sets the type to DatabaseTableIndex::PRIMARY_TYPE. To drop a index, all of the relevant data to create the index has to be present and the drop() method has to be called.

    The index name is specified as the parameter to DatabaseTableIndex::create(). It is strongly recommended to specify an explicit name (WoltLab/WCF#4505). If no name is given, DatabaseTable::indices() will automatically set one based on the index data.

    There is a list of all default PIPs available.

    Both the type-attribute and the element value are case-sensitive. Windows does not care if the file is called objecttypedefinition.xml but was referenced as objectTypeDefinition.xml, but both Linux and Mac systems will be unable to find the file.

    In addition to the type attribute, an optional run attribute (with standalone as the only valid value) is supported which forces the installation to execute this PIP in an isolated request, allowing a single, resource-heavy PIP to execute without encountering restrictions such as PHP\u2019s memory_limit or max_execution_time:

    Apps are among the most powerful components in WoltLab Suite. Unlike plugins that extend an existing functionality and pages, apps have their own frontend with a dedicated namespace, database table prefixes and template locations.

    However, apps are meant to be a logical (and to some extent physical) separation from other parts of the framework, including other installed apps. They offer an additional layer of isolation and enable you to re-use class and template names that are already in use by the Core itself.

    If you've come here, thinking about the question if your next package should be an app instead of a regular plugin, the result is almost always: No.

    "},{"location":"php/apps/#differences-to-plugins","title":"Differences to Plugins","text":"

    Apps do offer a couple of unique features that are not available to plugins and there are valid reasons to use one instead of a plugin, but they also increase both the code and system complexity. There is a performance penalty for each installed app, regardless if it is actively used in a request or not, simplying being there forces the Core to include it in many places, for example, class resolution or even simple tasks such as constructing a link.

    "},{"location":"php/apps/#unique-namespace","title":"Unique Namespace","text":"

    Each app has its own unique namespace that is entirely separated from the Core and any other installed apps. The namespace is derived from the last part of the package identifier, for example, com.example.foo will yield the namespace foo.

    The namespace is always relative to the installation directory of the app, it doesn't matter if the app is installed on example.com/foo/ or in example.com/bar/, the namespace will always resolve to the right directory.

    This app namespace is also used for ACP templates, frontend templates and files:

    <!-- somewhere in the package.xml -->\n<instructions type=\"file\" application=\"foo\" />\n
    "},{"location":"php/apps/#unique-database-table-prefix","title":"Unique Database Table Prefix","text":"

    All database tables make use of a generic prefix that is derived from one of the installed apps, including wcf which resolves to the Core itself. Following the aforementioned example, the new prefix fooN_ will be automatically registered and recognized in any generated statement.

    Any DatabaseObject that uses the app's namespace is automatically assumed to use the app's database prefix. For instance, foo\\data\\bar\\Bar is implicitly mapped to the database table fooN_bar.

    The app prefix is recognized in SQL-PIPs and statements that reference one of its database tables are automatically rewritten to use the Core's instance number.

    "},{"location":"php/apps/#separate-domain-and-path-configuration","title":"Separate Domain and Path Configuration","text":"

    Any controller that is provided by a plugin is served from the configured domain and path of the corresponding app, such as plugins for the Core are always served from the Core's directory. Apps are different and use their own domain and/or path to present their content, additionally, this allows the app to re-use a controller name that is already provided by the Core or any other app itself.

    "},{"location":"php/apps/#creating-an-app","title":"Creating an App","text":"

    This is a non-reversible operation! Once a package has been installed, its type cannot be changed without uninstalling and reinstalling the entire package, an app will always be an app and vice versa.

    As the database table columns are not explicit properties of the classes extending wcf\\data\\DatabaseObject but rather stored in DatabaseObject::$data and accessible via DatabaseObject::__get($name), the IDE we use, PhpStorm, is neither able to autocomplete such property access nor to interfere the type of the property.

    To solve this problem, @property-read tags must be added to the class documentation which registers the database table columns as public read-only properties:

     * @property-read   propertyType    $propertyName   property description\n

    The properties have to be in the same order as the order in the database table.

    The only exception to this rule is if the class overwrites the create() method which itself has to be properly documentation then.

    The first and second line makes sure that when calling the create() or getDecoratedObject() method, the return value is correctly recognized and not just a general DatabaseObject instance.

    The condition and the values should be short so that the code does not result in a very long line which thus decreases the readability compared to an if-else statement.

    Parentheses may only be used around the condition and not around the whole statement:

    <?php\n\n// do not do it like this\n$name = (isset($tagArgs['name']) ? $tagArgs['name'] : 'default');\n

    Parentheses around the conditions may not be used to wrap simple function calls:

    Database Objects provide a convenient and object-oriented approach to work with the database, but there can be use-cases that require raw access including writing methods for model classes. This section assumes that you have either used prepared statements before or at least understand how it works.

    "},{"location":"php/database-access/#the-preparedstatement-object","title":"The PreparedStatement Object","text":"

    The database access is designed around PreparedStatement, built on top of PHP's PDOStatement so that you call all of PDOStatement's methods, and each query requires you to obtain a statement object.

    <?php\n$statement = \\wcf\\system\\WCF::getDB()->prepare(\"SELECT * FROM wcf1_example\");\n$statement->execute();\nwhile ($row = $statement->fetchArray()) {\n    // handle result\n}\n
    "},{"location":"php/database-access/#query-parameters","title":"Query Parameters","text":"

    The example below illustrates the usage of parameters where each value is replaced with the generic ?-placeholder. Values are provided by calling $statement->execute() with a continuous, one-dimensional array that exactly match the number of question marks.

    <?php\n$sql = \"SELECT  *\n        FROM    wcf1_example\n        WHERE   exampleID = ?\n                OR bar IN (?, ?, ?, ?, ?)\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute([\n    $exampleID,\n    $list, $of, $values, $for, $bar\n]);\nwhile ($row = $statement->fetchArray()) {\n    // handle result\n}\n
    "},{"location":"php/database-access/#fetching-a-single-result","title":"Fetching a Single Result","text":"

    Do not attempt to use fetchSingleRow() or fetchSingleColumn() if the result contains more than one row.

    You can opt-in to retrieve only a single row from database and make use of shortcut methods to reduce the code that you have to write.

    <?php\n$sql = \"SELECT  *\n        FROM    wcf1_example\n        WHERE   exampleID = ?\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql, 1);\n$statement->execute([$exampleID]);\n$row = $statement->fetchSingleRow();\n

    There are two distinct differences when comparing with the example on query parameters above:

    1. The method prepare() receives a secondary parameter that will be appended to the query as LIMIT 1.
    2. Data is read using fetchSingleRow() instead of fetchArray() or similar methods, that will read one result and close the cursor.
    "},{"location":"php/database-access/#fetch-by-column","title":"Fetch by Column","text":"

    There is no way to return another column from the same row if you use fetchColumn() to retrieve data.

    Fetching an array is only useful if there is going to be more than one column per result row, otherwise accessing the column directly is much more convenient and increases the code readability.

    <?php\n$sql = \"SELECT  bar\n        FROM    wcf1_example\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\nwhile ($bar = $statement->fetchColumn()) {\n    // handle result\n}\n$bar = $statement->fetchSingleColumn();\n

    Similar to fetching a single row, you can also issue a query that will select a single row, but reads only one column from the result row.

    <?php\n$sql = \"SELECT  bar\n        FROM    wcf1_example\n        WHERE   exampleID = ?\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql, 1);\n$statement->execute([$exampleID]);\n$bar = $statement->fetchSingleColumn();\n
    "},{"location":"php/database-access/#fetching-all-results","title":"Fetching All Results","text":"

    If you want to fetch all results of a query but only store them in an array without directly processing them, in most cases, you can rely on built-in methods.

    To fetch all rows of query, you can use PDOStatement::fetchAll() with \\PDO::FETCH_ASSOC as the first parameter:

    <?php\n$sql = \"SELECT  *\n        FROM    wcf1_example\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$rows = $statement->fetchAll(\\PDO::FETCH_ASSOC);\n

    As a result, you get an array containing associative arrays with the rows of the wcf{WCF_N}_example database table as content.

    If you only want to fetch a list of the values of a certain column, you can use \\PDO::FETCH_COLUMN as the first parameter:

    <?php\n$sql = \"SELECT  exampleID\n        FROM    wcf1_example\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$exampleIDs = $statement->fetchAll(\\PDO::FETCH_COLUMN);\n

    As a result, you get an array with all exampleID values.

    The PreparedStatement class adds an additional methods that covers another common use case in our code: Fetching two columns and using the first column's value as the array key and the second column's value as the array value. This case is covered by PreparedStatement::fetchMap():

    <?php\n$sql = \"SELECT  exampleID, userID\n        FROM    wcf1_example_mapping\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$map = $statement->fetchMap('exampleID', 'userID');\n

    $map is a one-dimensional array where each exampleID value maps to the corresponding userID value.

    If there are multiple entries for a certain exampleID value with different userID values, the existing entry in the array will be overwritten and contain the last read value from the database table. Therefore, this method should generally only be used for unique combinations.

    If you do not have a combination of columns with unique pairs of values, but you want to get a list of userID values with the same exampleID, you can set the third parameter of fetchMap() to false and get a list:

    <?php\n$sql = \"SELECT  exampleID, userID\n        FROM    wcf1_example_mapping\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$map = $statement->fetchMap('exampleID', 'userID', false);\n

    Now, as a result, you get a two-dimensional array with the array keys being the exampleID values and the array values being arrays with all userID values from rows with the respective exampleID value.

    "},{"location":"php/database-access/#building-complex-conditions","title":"Building Complex Conditions","text":"

    Building conditional conditions can turn out to be a real mess and it gets even worse with SQL's IN (\u2026) which requires as many placeholders as there will be values. The solutions is PreparedStatementConditionBuilder, a simple but useful helper class with a bulky name, it is also the class used when accessing DatabaseObjecList::getConditionBuilder().

    <?php\n$conditions = new \\wcf\\system\\database\\util\\PreparedStatementConditionBuilder();\n$conditions->add(\"exampleID = ?\", [$exampleID]);\nif (!empty($valuesForBar)) {\n    $conditions->add(\"(bar IN (?) OR baz = ?)\", [$valuesForBar, $baz]);\n}\n

    The IN (?) in the example above is automatically expanded to match the number of items contained in $valuesForBar. Be aware that the method will generate an invalid query if $valuesForBar is empty!

    "},{"location":"php/database-access/#insert-or-update-in-bulk","title":"INSERT or UPDATE in Bulk","text":"

    Prepared statements not only protect against SQL injection by separating the logical query and the actual data, but also provides the ability to reuse the same query with different values. This leads to a performance improvement as the code does not have to transmit the query with for every data set and only has to parse and analyze the query once.

    <?php\n$data = ['abc', 'def', 'ghi'];\n\n$sql = \"INSERT INTO  wcf1_example\n                     (bar)\n        VALUES       (?)\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n\n\\wcf\\system\\WCF::getDB()->beginTransaction();\nforeach ($data as $bar) {\n    $statement->execute([$bar]);\n}\n\\wcf\\system\\WCF::getDB()->commitTransaction();\n

    It is generally advised to wrap bulk operations in a transaction as it allows the database to optimize the process, including fewer I/O operations.

    <?php\n$data = [\n    1 => 'abc',\n    3 => 'def',\n    4 => 'ghi'\n];\n\n$sql = \"UPDATE  wcf1_example\n        SET     bar = ?\n        WHERE   exampleID = ?\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n\n\\wcf\\system\\WCF::getDB()->beginTransaction();\nforeach ($data as $exampleID => $bar) {\n    $statement->execute([\n        $bar,\n        $exampleID\n    ]);\n}\n\\wcf\\system\\WCF::getDB()->commitTransaction();\n

    WoltLab Suite uses a unified interface to work with database rows using an object based approach instead of using native arrays holding arbitrary data. Each database table is mapped to a model class that is designed to hold a single record from that table and expose methods to work with the stored data, for example providing assistance when working with normalized datasets.

    Developers are required to provide the proper DatabaseObject implementations themselves, they're not automatically generated, all though the actual code that needs to be written is rather small. The following examples assume the fictional database table wcf1_example, exampleID as the auto-incrementing primary key and the column bar to store some text.

    "},{"location":"php/database-objects/#databaseobject","title":"DatabaseObject","text":"

    The basic model derives from wcf\\data\\DatabaseObject and provides a convenient constructor to fetch a single row or construct an instance using pre-loaded rows.

    files/lib/data/example/Example.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObject;\n\nclass Example extends DatabaseObject {}\n

    The class is intended to be empty by default and there only needs to be code if you want to add additional logic to your model. Both the class name and primary key are determined by DatabaseObject using the namespace and class name of the derived class. The example above uses the namespace wcf\\\u2026 which is used as table prefix and the class name Example is converted into exampleID, resulting in the database table name wcfN_example with the primary key exampleID.

    You can prevent this automatic guessing by setting the class properties $databaseTableName and $databaseTableIndexName manually.

    "},{"location":"php/database-objects/#databaseobjectdecorator","title":"DatabaseObjectDecorator","text":"

    If you already have a DatabaseObject class and would like to extend it with additional data or methods, for example by providing a class ViewableExample which features view-related changes without polluting the original object, you can use DatabaseObjectDecorator which a default implementation of a decorator for database objects.

    files/lib/data/example/ViewableExample.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObjectDecorator;\n\nclass ViewableExample extends DatabaseObjectDecorator {\n    protected static $baseClass = Example::class;\n\n    public function getOutput() {\n        $output = '';\n\n        // [determine output]\n\n        return $output;\n    }\n}\n

    It is mandatory to set the static $baseClass property to the name of the decorated class.

    Like for any decorator, you can directly access the decorated object's properties and methods for a decorated object by accessing the property or calling the method on the decorated object. You can access the decorated objects directly via DatabaseObjectDecorator::getDecoratedObject().

    "},{"location":"php/database-objects/#databaseobjecteditor","title":"DatabaseObjectEditor","text":"

    This is the low-level interface to manipulate data rows, it is recommended to use AbstractDatabaseObjectAction.

    Adding, editing and deleting models is done using the DatabaseObjectEditor class that decorates a DatabaseObject and uses its data to perform the actions.

    files/lib/data/example/ExampleEditor.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObjectEditor;\n\nclass ExampleEditor extends DatabaseObjectEditor {\n    protected static $baseClass = Example::class;\n}\n

    The editor class requires you to provide the fully qualified name of the model, that is the class name including the complete namespace. Database table name and index key will be pulled directly from the model.

    "},{"location":"php/database-objects/#create-a-new-row","title":"Create a new row","text":"

    Inserting a new row into the database table is provided through DatabaseObjectEditor::create() which yields a DatabaseObject instance after creation.

    "},{"location":"php/database-objects/#updating-an-existing-row","title":"Updating an existing row","text":"

    The internal state of the decorated DatabaseObject is not altered at any point, the values will still be the same after editing or deleting the represented row. If you need an object with the latest data, you'll have to discard the current object and refetch the data from database.

    <?php\n$example = new \\wcf\\data\\example\\Example($id);\n$exampleEditor = new \\wcf\\data\\example\\ExampleEditor($example);\n$exampleEditor->update([\n    'bar' => 'baz'\n]);\n\n// output: Hello World!\necho $example->bar;\n\n// re-creating the object will query the database again and retrieve the updated value\n$example = new \\wcf\\data\\example\\Example($example->id);\n\n// output: baz\necho $example->bar;\n

    Similar to the update process, the decorated DatabaseObject is not altered and will then point to an inexistent row.

    Every row is represented as a single instance of the model, but the instance creation deals with single rows only. Retrieving larger sets of rows would be quite inefficient due to the large amount of queries that will be dispatched. This is solved with the DatabaseObjectList object that exposes an interface to query the database table using arbitrary conditions for data selection. All rows will be fetched using a single query and the resulting rows are automatically loaded into separate models.

    files/lib/data/example/ExampleList.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObjectList;\n\nclass ExampleList extends DatabaseObjectList {\n    public $className = Example::class;\n}\n

    The following code listing illustrates loading a large set of examples and iterating over the list to retrieve the objects.

    <?php\n$exampleList = new \\wcf\\data\\example\\ExampleList();\n// add constraints using the condition builder\n$exampleList->getConditionBuilder()->add('bar IN (?)', [['Hello World!', 'bar', 'baz']]);\n// actually read the rows\n$exampleList->readObjects();\nforeach ($exampleList as $example) {\n    echo $example->bar;\n}\n\n// retrieve the models directly instead of iterating over them\n$examples = $exampleList->getObjects();\n\n// just retrieve the number of rows\n$exampleCount = $exampleList->countObjects();\n

    DatabaseObjectList implements both SeekableIterator and Countable.

    Additionally, DatabaseObjectList objects has the following three public properties that are useful when fetching data with lists:

    For more advanced usage, there two additional fields that deal with the type of objects returned. First, let's go into a bit more detail what setting the $className property actually does:

    1. It is the type of database object in which the rows are wrapped.
    2. It determines which database table is actually queried and which index is used (see the $databaseTableName and $databaseTableIndexName properties of DatabaseObject).

    Sometimes you might use the database table of some database object but wrap the rows in another database object. This can be achieved by setting the $objectClassName property to the desired class name.

    In other cases, you might want to wrap the created objects in a database object decorator which can be done by setting the $decoratorClassName property to the desired class name:

    <?php\n$exampleList = new \\wcf\\data\\example\\ExampleList();\n$exampleList->decoratorClassName = \\wcf\\data\\example\\ViewableExample::class;\n

    Of course, you do not have to set the property after creating the list object, you can also set it by creating a dedicated class:

    files/lib/data/example/ViewableExampleList.class.php 
    <?php\nnamespace wcf\\data\\example;\n\nclass ViewableExampleList extends ExampleList {\n    public $decoratorClassName = ViewableExample::class;\n}\n
    "},{"location":"php/database-objects/#abstractdatabaseobjectaction","title":"AbstractDatabaseObjectAction","text":"

    Row creation and manipulation can be performed using the aforementioned DatabaseObjectEditor class, but this approach has two major issues:

    1. Row creation, update and deletion takes place silently without notifying any other components.
    2. Data is passed to the database adapter without any further processing.

    The AbstractDatabaseObjectAction solves both problems by wrapping around the editor class and thus provide an additional layer between the action that should be taken and the actual process. The first problem is solved by a fixed set of events being fired, the second issue is addressed by having a single entry point for all data editing.

    files/lib/data/example/ExampleAction.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\AbstractDatabaseObjectAction;\n\nclass ExampleAction extends AbstractDatabaseObjectAction {\n    public $className = ExampleEditor::class;\n}\n

    The method AbstractDatabaseObjectAction::validateAction() is internally used for AJAX method invocation and must not be called programmatically.

    The next example represents the same functionality as seen for DatabaseObjectEditor:

    Sometimes sensitive values are passed as a function or method argument. If the callee throws an Exception, these values will be part of the Exception\u2019s stack trace and logged, unless the Exception is caught and ignored.

    WoltLab Suite will automatically suppress the values of parameters named like they might contain sensitive values, namely arguments matching the regular expression /(?:^(?:password|passphrase|secret)|(?:Password|Passphrase|Secret))/.

    If you need to suppress additional arguments from appearing in the stack trace, you can add the \\wcf\\SensitiveArgument attribute to such parameters. Arguments are only supported as of PHP 8 and ignored as comments in lower PHP versions. In PHP 7, such arguments will not be suppressed, but the code will continue to work.

    WoltLab Suite offers two distinct types of caches:

    1. Persistent caches created by cache builders whose data can be stored using different cache sources.
    2. Runtime caches store objects for the duration of a single request.
    "},{"location":"php/api/caches/#understanding-caching","title":"Understanding Caching","text":"

    Every so often, plugins make use of cache builders or runtime caches to store their data, even if there is absolutely no need for them to do so. Usually, this involves a strong opinion about the total number of SQL queries on a page, including but not limited to some magic treshold numbers, which should not be exceeded for \"performance reasons\".

    This misconception can easily lead into thinking that SQL queries should be avoided or at least written to a cache, so that it doesn't need to be executed so often. Unfortunately, this completely ignores the fact that both a single query can take down your app (e. g. full table scan on millions of rows), but 10 queries using a primary key on a table with a few hundred rows will not slow down your page.

    There are some queries that should go into caches by design, but most of the cache builders weren't initially there, but instead have been added because they were required to reduce the load significantly. You need to understand that caches always come at a cost, even a runtime cache does! In particular, they will always consume memory that is not released over the duration of the request lifecycle and potentially even leak memory by holding references to objects and data structures that are no longer required.

    Caching should always be a solution for a problem.

    "},{"location":"php/api/caches/#when-to-use-a-cache","title":"When to Use a Cache","text":"

    It's difficult to provide a definite answer or checklist when to use a cache and why it is required at this point, because the answer is: It depends. The permission cache for user groups is a good example for a valid cache, where we can achieve significant performance improvement compared to processing this data on every request.

    Its caches are build for each permutation of user group memberships that are encountered for a page request. Building this data is an expensive process that involves both inheritance and specific rules in regards to when a value for a permission overrules another value. The added benefit of this cache is that one cache usually serves a large number of users with the same group memberships and by computing these permissions once, we can serve many different requests. Also, the permissions are rather static values that change very rarely and thus we can expect a very high cache lifetime before it gets rebuild.

    "},{"location":"php/api/caches/#when-not-to-use-a-cache","title":"When not to Use a Cache","text":"

    I remember, a few years ago, there was a plugin that displayed a user's character from an online video game. The character sheet not only included a list of basic statistics, but also displayed the items that this character was wearing and or holding at the time.

    The data for these items were downloaded in bulk from the game's vendor servers and stored in a persistent cache file that periodically gets renewed. There is nothing wrong with the idea of caching the data on your own server rather than requesting them everytime from the vendor's servers - not only because they imposed a limit on the number of requests per hour.

    Unfortunately, the character sheet had a sub-par performance and the users were upset by the significant loading times compared to literally every other page on the same server. The author of the plugin was working hard to resolve this issue and was evaluating all kind of methods to improve the page performance, including deep-diving into the realm of micro-optimizations to squeeze out every last bit of performance that is possible.

    The real problem was the cache file itself, it turns out that it was holding the data for several thousand items with a total file size of about 13 megabytes. It doesn't look that much at first glance, after all this isn't the '90s anymore, but unserializing a 13 megabyte array is really slow and looking up items in such a large array isn't exactly fast either.

    The solution was rather simple, the data that was fetched from the vendor's API was instead written into a separate database table. Next, the persistent cache was removed and the character sheet would now request the item data for that specific character straight from the database. Previously, the character sheet took several seconds to load and after the change it was done in a fraction of a second. Although quite extreme, this illustrates a situation where the cache file was introduced in the design process, without evaluating if the cache - at least how it was implemented - was really necessary.

    Caching should always be a solution for a problem. Not the other way around.

    "},{"location":"php/api/caches_persistent-caches/","title":"Persistent Caches","text":"

    Relational databases are designed around the principle of normalized data that is organized across clearly separated tables with defined releations between data rows. While this enables you to quickly access and modify individual rows and columns, it can create the problem that re-assembling this data into a more complex structure can be quite expensive.

    For example, the user group permissions are stored for each user group and each permissions separately, but in order to be applied, they need to be fetched and the cumulative values across all user groups of an user have to be calculated. These repetitive tasks on barely ever changing data make them an excellent target for caching, where all sub-sequent requests are accelerated because they no longer have to perform the same expensive calculations every time.

    It is easy to get lost in the realm of caching, especially when it comes to the decision if you should use a cache or not. When in doubt, you should opt to not use them, because they also come at a hidden cost that cannot be expressed through simple SQL query counts. If you haven't already, it is recommended that you read the introduction article on caching first, it provides a bit of background on caches and examples that should help you in your decision.

    "},{"location":"php/api/caches_persistent-caches/#abstractcachebuilder","title":"AbstractCacheBuilder","text":"

    Reading data from your cache builder is quite simple and follows a consistent pattern. The callee only needs to know the name of the cache builder, which parameters it requires and how the returned data looks like. It does not need to know how the data is retrieve, where it was stored, nor if it had to be rebuild due to the maximum lifetime.

    Runtime caches store objects created during the runtime of the script and are automatically discarded after the script terminates. Runtime caches are especially useful when objects are fetched by different APIs, each requiring separate requests. By using a runtime cache, you have two advantages:

    1. If the API allows it, you can delay fetching the actual objects and initially only tell the runtime cache that at some point in the future of the current request, you need the objects with the given ids. If multiple APIs do this one after another, all objects can be fetched using only one query instead of each API querying the database on its own.
    2. If an object with the same ID has already been fetched from database, this object is simply returned and can be reused instead of being fetched from database again.

    WoltLab Suite's event system allows manipulation of program flows and data without having to change any of the original source code. At many locations throughout the PHP code of WoltLab Suite Core and mainly through inheritance also in the applications and plugins, so called events are fired which trigger registered event listeners that get access to the object firing the event (or at least the class name if the event has been fired in a static method).

    This page focuses on the technical aspects of events and event listeners, the eventListener package installation plugin page covers how you can actually register an event listener. A comprehensive list of all available events is provided here.

    "},{"location":"php/api/events/#introductory-example","title":"Introductory Example","text":"

    Let's start with a simple example to illustrate how the event system works. Consider this pre-existing class:

    files/lib/system/example/ExampleComponent.class.php 
    <?php\nnamespace wcf\\system\\example;\nuse wcf\\system\\event\\EventHandler;\n\nclass ExampleComponent {\n    public $var = 1;\n\n    public function getVar() {\n        EventHandler::getInstance()->fireAction($this, 'getVar');\n\n        return $this->var;\n    }\n}\n

    where an event with event name getVar is fired in the getVar() method.

    If you create an object of this class and call the getVar() method, the return value will be 1, of course:

    <?php\n\n$example = new wcf\\system\\example\\ExampleComponent();\nif ($example->getVar() == 1) {\n    echo \"var is 1!\";\n}\nelse if ($example->getVar() == 2) {\n    echo \"var is 2!\";\n}\nelse {\n    echo \"No, var is neither 1 nor 2.\";\n}\n\n// output: var is 1!\n

    Now, consider that we have registered the following event listener to this event:

    files/lib/system/event/listener/ExampleEventListener.class.php 
    <?php\nnamespace wcf\\system\\event\\listener;\n\nclass ExampleEventListener implements IParameterizedEventListener {\n    public function execute($eventObj, $className, $eventName, array &$parameters) {\n        $eventObj->var = 2;\n    }\n}\n

    Whenever the event in the getVar() method is called, this method (of the same event listener object) is called. In this case, the value of the method's first parameter is the ExampleComponent object passed as the first argument of the EventHandler::fireAction() call in ExampleComponent::getVar(). As ExampleComponent::$var is a public property, the event listener code can change it and set it to 2.

    If you now execute the example code from above again, the output will change from var is 1! to var is 2! because prior to returning the value, the event listener code changes the value from 1 to 2.

    This introductory example illustrates how event listeners can change data in a non-intrusive way. Program flow can be changed, for example, by throwing a wcf\\system\\exception\\PermissionDeniedException if some additional constraint to access a page is not fulfilled.

    "},{"location":"php/api/events/#listening-to-events","title":"Listening to Events","text":"

    In order to listen to events, you need to register the event listener and the event listener itself needs to implement the interface wcf\\system\\event\\listener\\IParameterizedEventListener which only contains the execute method (see example above).

    The first parameter $eventObj of the method contains the passed object where the event is fired or the name of the class in which the event is fired if it is fired from a static method. The second parameter $className always contains the name of the class where the event has been fired. The third parameter $eventName provides the name of the event within a class to uniquely identify the exact location in the class where the event has been fired. The last parameter $parameters is a reference to the array which contains additional data passed by the method firing the event. If no additional data is passed, $parameters is empty.

    "},{"location":"php/api/events/#firing-events","title":"Firing Events","text":"

    If you write code and want plugins to have access at certain points, you can fire an event on your own. The only thing to do is to call the wcf\\system\\event\\EventHandler::fireAction($eventObj, $eventName, array &$parameters = []) method and pass the following parameters:

    1. $eventObj should be $this if you fire from an object context, otherwise pass the class name static::class.
    2. $eventName identifies the event within the class and generally has the same name as the method. In cases, were you might fire more than one event in a method, for example before and after a certain piece of code, you can use the prefixes before* and after* in your event names.
    3. $parameters is an optional array which allows you to pass additional data to the event listeners without having to make this data accessible via a property explicitly only created for this purpose. This additional data can either be just additional information for the event listeners about the context of the method call or allow the event listener to manipulate local data if the code, where the event has been fired, uses the passed data afterwards.
    "},{"location":"php/api/events/#example-using-parameters-argument","title":"Example: Using $parameters argument","text":"

    Consider the following method which gets some text that the methods parses.

    files/lib/system/example/ExampleParser.class.php 
    <?php\nnamespace wcf\\system\\example;\nuse wcf\\system\\event\\EventHandler;\n\nclass ExampleParser {\n    public function parse($text) {\n        // [some parsing done by default]\n\n        $parameters = ['text' => $text];\n        EventHandler::getInstance()->fireAction($this, 'parse', $parameters);\n\n        return $parameters['text'];\n    }\n}\n

    After the default parsing by the method itself, the author wants to enable plugins to do additional parsing and thus fires an event and passes the parsed text as an additional parameter. Then, a plugin can deliver the following event listener

    files/lib/system/event/listener/ExampleParserEventListener.class.php 
    <?php\nnamespace wcf\\system\\event\\listener;\n\nclass ExampleParserEventListener implements IParameterizedEventListener {\n    public function execute($eventObj, $className, $eventName, array &$parameters) {\n        $text = $parameters['text'];\n\n        // [some additional parsing which changes $text]\n\n        $parameters['text'] = $text;\n    }\n}\n

    which can access the text via $parameters['text'].

    This example can also be perfectly used to illustrate how to name multiple events in the same method. Let's assume that the author wants to enable plugins to change the text before and after the method does its own parsing and thus fires two events:

    files/lib/system/example/ExampleParser.class.php 
    <?php\nnamespace wcf\\system\\example;\nuse wcf\\system\\event\\EventHandler;\n\nclass ExampleParser {\n    public function parse($text) {\n        $parameters = ['text' => $text];\n        EventHandler::getInstance()->fireAction($this, 'beforeParsing', $parameters);\n        $text = $parameters['text'];\n\n        // [some parsing done by default]\n\n        $parameters = ['text' => $text];\n        EventHandler::getInstance()->fireAction($this, 'afterParsing', $parameters);\n\n        return $parameters['text'];\n    }\n}\n
    "},{"location":"php/api/events/#advanced-example-additional-form-field","title":"Advanced Example: Additional Form Field","text":"

    One common reason to use event listeners is to add an additional field to a pre-existing form (in combination with template listeners, which we will not cover here). We will assume that users are able to do both, create and edit the objects via this form. The points in the program flow of AbstractForm that are relevant here are:

    All of these cases can be covered the by following code in which we assume that wcf\\form\\ExampleAddForm is the form to create example objects and that wcf\\form\\ExampleEditForm extends wcf\\form\\ExampleAddForm and is used for editing existing example objects.

    files/lib/system/event/listener/ExampleAddFormListener.class.php 
    <?php\nnamespace wcf\\system\\event\\listener;\nuse wcf\\form\\ExampleAddForm;\nuse wcf\\form\\ExampleEditForm;\nuse wcf\\system\\exception\\UserInputException;\nuse wcf\\system\\WCF;\n\nclass ExampleAddFormListener implements IParameterizedEventListener {\n    protected $var = 0;\n\n    public function execute($eventObj, $className, $eventName, array &$parameters) {\n        $this->$eventName($eventObj);\n    }\n\n    protected function assignVariables() {\n        WCF::getTPL()->assign('var', $this->var);\n    }\n\n    protected function readData(ExampleEditForm $eventObj) {\n        if (empty($_POST)) {\n            $this->var = $eventObj->example->var;\n        }\n    }\n\n    protected function readFormParameters() {\n        if (isset($_POST['var'])) $this->var = intval($_POST['var']);\n    }\n\n    protected function save(ExampleAddForm $eventObj) {\n        $eventObj->additionalFields = array_merge($eventObj->additionalFields, ['var' => $this->var]);\n    }\n\n    protected function saved() {\n        $this->var = 0;\n    }\n\n    protected function validate() {\n        if ($this->var < 0) {\n            throw new UserInputException('var', 'isNegative');\n        }\n    }\n}\n

    The execute method in this example just delegates the call to a method with the same name as the event so that this class mimics the structure of a form class itself. The form object is passed to the methods but is only given in the method signatures as a parameter here whenever the form object is actually used. Furthermore, the type-hinting of the parameter illustrates in which contexts the method is actually called which will become clear in the following discussion of the individual methods:

    Lastly, the following XML file has to be used to register the event listeners (you can find more information about how to register event listeners on the eventListener package installation plugin page):

    eventListener.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/2019/eventListener.xsd\">\n<import>\n<eventlistener name=\"exampleAddInherited\">\n<eventclassname>wcf\\form\\ExampleAddForm</eventclassname>\n<eventname>assignVariables,readFormParameters,save,validate</eventname>\n<listenerclassname>wcf\\system\\event\\listener\\ExampleAddFormListener</listenerclassname>\n<inherit>1</inherit>\n</eventlistener>\n\n<eventlistener name=\"exampleAdd\">\n<eventclassname>wcf\\form\\ExampleAddForm</eventclassname>\n<eventname>saved</eventname>\n<listenerclassname>wcf\\system\\event\\listener\\ExampleAddFormListener</listenerclassname>\n</eventlistener>\n\n<eventlistener name=\"exampleEdit\">\n<eventclassname>wcf\\form\\ExampleEditForm</eventclassname>\n<eventname>readData</eventname>\n<listenerclassname>wcf\\system\\event\\listener\\ExampleAddFormListener</listenerclassname>\n</eventlistener>\n</import>\n</data>\n

    WoltLab Suite is capable of automatically creating a sitemap. This sitemap contains all static pages registered via the page package installation plugin and which may be indexed by search engines (checking the allowSpidersToIndex parameter and page permissions) and do not expect an object ID. Other pages have to be added to the sitemap as a separate object.

    The only prerequisite for sitemap objects is that the objects are instances of wcf\\data\\DatabaseObject and that there is a wcf\\data\\DatabaseObjectList implementation.

    First, we implement the PHP class, which provides us all database objects and optionally checks the permissions for a single object. The class must implement the interface wcf\\system\\sitemap\\object\\ISitemapObjectObjectType. However, in order to have some methods already implemented and ensure backwards compatibility, you should use the abstract class wcf\\system\\sitemap\\object\\AbstractSitemapObjectObjectType. The abstract class takes care of generating the DatabaseObjectList class name and list directly and implements optional methods with the default values. The only method that you have to implement yourself is the getObjectClass() method which returns the fully qualified name of the DatabaseObject class. The DatabaseObject class must implement the interface wcf\\data\\ILinkableObject.

    Other optional methods are:

    As an example, the implementation for users looks like this:

    files/lib/system/sitemap/object/UserSitemapObject.class.php 
    <?php\nnamespace wcf\\system\\sitemap\\object;\nuse wcf\\data\\user\\User;\nuse wcf\\data\\DatabaseObject;\nuse wcf\\system\\WCF;\n\n/**\n * User sitemap implementation.\n *\n * @author  Joshua Ruesweg\n * @copyright   2001-2017 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\Sitemap\\Object\n * @since   3.1\n */\nclass UserSitemapObject extends AbstractSitemapObjectObjectType {\n    /**\n     * @inheritDoc\n     */\n    public function getObjectClass() {\n        return User::class;\n    }\n\n    /**\n     * @inheritDoc\n     */\n    public function getLastModifiedColumn() {\n        return 'lastActivityTime';\n    }\n\n    /**\n     * @inheritDoc\n     */\n    public function canView(DatabaseObject $object) {\n        return WCF::getSession()->getPermission('user.profile.canViewUserProfile');\n    }\n}\n

    Next, the sitemap object must be registered as an object type:

    <type>\n<name>com.example.plugin.sitemap.object.user</name>\n<definitionname>com.woltlab.wcf.sitemap.object</definitionname>\n<classname>wcf\\system\\sitemap\\object\\UserSitemapObject</classname>\n<priority>0.5</priority>\n<changeFreq>monthly</changeFreq>\n<rebuildTime>259200</rebuildTime>\n</type>\n

    In addition to the fully qualified class name, the object type definition com.woltlab.wcf.sitemap.object and the object type name, the parameters priority, changeFreq and rebuildTime must also be specified. priority (https://www.sitemaps.org/protocol.html#prioritydef) and changeFreq (https://www.sitemaps.org/protocol.html#changefreqdef) are specifications in the sitemaps protocol and can be changed by the user in the ACP. The priority should be 0.5 by default, unless there is an important reason to change it. The parameter rebuildTime specifies the number of seconds after which the sitemap should be regenerated.

    Finally, you have to create the language variable for the sitemap object. The language variable follows the pattern wcf.acp.sitemap.objectType.{objectTypeName} and is in the category wcf.acp.sitemap.

    "},{"location":"php/api/user_activity_points/","title":"User Activity Points","text":"

    Users get activity points whenever they create content to award them for their contribution. Activity points are used to determine the rank of a user and can also be used for user conditions, for example for automatic user group assignments.

    To integrate activity points into your package, you have to register an object type for the defintion com.woltlab.wcf.user.activityPointEvent and specify a default number of points:

    <type>\n<name>com.example.foo.activityPointEvent.bar</name>\n<definitionname>com.woltlab.wcf.user.activityPointEvent</definitionname>\n<points>10</points>\n</type>\n

    The number of points awarded for this type of activity point event can be changed by the administrator in the admin control panel. For this form and the user activity point list shown in the frontend, you have to provide the language item

    wcf.user.activityPoint.objectType.com.example.foo.activityPointEvent.bar\n

    that contains the name of the content for which the activity points are awarded.

    If a relevant object is created, you have to use UserActivityPointHandler::fireEvent() which expects the name of the activity point event object type, the id of the object for which the points are awarded (though the object id is not used at the moment) and the user who gets the points:

    UserActivityPointHandler::getInstance()->fireEvent(\n        'com.example.foo.activityPointEvent.bar',\n        $bar->barID,\n        $bar->userID\n);\n

    To remove activity points once objects are deleted, you have to use UserActivityPointHandler::removeEvents() which also expects the name of the activity point event object type and additionally an array mapping the id of the user whose activity points will be reduced to the number of objects that are removed for the relevant user:

    UserActivityPointHandler::getInstance()->removeEvents(\n        'com.example.foo.activityPointEvent.bar',\n       [\n                1 => 1, // remove points for one object for user with id `1`\n                4 => 2  // remove points for two objects for user with id `4`\n        ]\n);\n

    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/2019/objectType.xsd\">\n<import>\n<type>\n<name>com.woltlab.example.foo</name>\n<definitionname>com.woltlab.wcf.notification.objectType</definitionname>\n<classname>example\\system\\user\\notification\\object\\type\\FooUserNotificationObjectType</classname>\n<category>com.woltlab.example</category>\n</type>\n</import>\n</data>\n

    The referenced class FooUserNotificationObjectType has to implement the IUserNotificationObjectType interface, which should be done by extending AbstractUserNotificationObjectType.

    You have to set the class names of the database object ($objectClassName) and the related list ($objectListClassName). Additionally, you have to create a class that implements the IUserNotificationObject whose name you have to set as the value of the $decoratorClassName property.

    Each event that you fire in your package needs to be registered using the user notification event package installation plugin. An example file might look like this:

    userNotificationEvent.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/2019/userNotificationEvent.xsd\">\n<import>\n<event>\n<name>bar</name>\n<objecttype>com.woltlab.example.foo</objecttype>\n<classname>example\\system\\user\\notification\\event\\FooUserNotificationEvent</classname>\n<preset>1</preset>\n</event>\n</import>\n</data>\n

    Here, you reference the user notification object type created via objectType.xml. The referenced class in the <classname> element has to implement the IUserNotificationEvent interface by extending the AbstractUserNotificationEvent class or the AbstractSharedUserNotificationEvent class if you want to pre-load additional data before processing notifications. In AbstractSharedUserNotificationEvent::prepare(), you can, for example, tell runtime caches to prepare to load certain objects which then are loaded all at once when the objects are needed.

    For daily emails ($notificationType = 'daily'), only application, template, and variables are supported. - The getEmailTitle() returns the title of the instant email sent to the user. By default, getEmailTitle() simply calls getTitle(). - The getEventHash() method returns a hash by which user notifications are grouped. Here, we want to group them not by the actual Foo object but by its parent Baz object and thus overwrite the default implementation provided by AbstractUserNotificationEvent. - The getLink() returns the link to the Foo object the notification belongs to. - The getMessage() method and the getTitle() return the message and the title of the user notification respectively. By checking the value of count($this->getAuthors()), we check if the notification is stacked, thus if the event has been triggered for multiple users so that different languages items are used. If your notification event does not support stacking, this distinction is not necessary. - The prepare() method is called for each user notification before all user notifications are rendered. This allows to tell runtime caches to prepare to load objects later on (see Runtime Caches).

    Form node dependencies allow to make parts of a form dynamically available or unavailable depending on the values of form fields. Dependencies are always added to the object whose visibility is determined by certain form fields. They are not added to the form field\u2019s whose values determine the visibility! An example is a text form field that should only be available if a certain option from a single selection form field is selected. Form builder\u2019s dependency system supports such scenarios and also automatically making form containers unavailable once all of its children are unavailable.

    If a form node has multiple dependencies and one of them is not met, the form node is unavailable. A form node not being available due to dependencies has to the following consequences:

    "},{"location":"php/api/form_builder/dependencies/#iformfielddependency","title":"IFormFieldDependency","text":"

    The basis of the dependencies is the IFormFieldDependency interface that has to be implemented by every dependency class. The interface requires the following methods:

    AbstractFormFieldDependency provides default implementations for all methods except for checkDependency().

    Using fieldId($fieldId) instead of field(IFormField $field) makes sense when adding the dependency directly when setting up the form:

    $container->appendChildren([\n    FooField::create('a'),\n\n    BarField::create('b')\n        ->addDependency(\n            BazDependency::create('a')\n                ->fieldId('a')\n        )\n]);\n

    Here, without an additional assignment, the first field with id a cannot be accessed thus fieldId($fieldId) should be used as the id of the relevant field is known. When the form is built, all dependencies that only know the id of the relevant field and do not have a reference for the actual object are populated with the actual form field objects.

    To ensure that dependent node are correctly shown and hidden when changing the value of referenced form fields, every PHP dependency class has a corresponding JavaScript module that checks the dependency in the browser. Every JavaScript dependency has to extend WoltLabSuite/Core/Form/Builder/Field/Dependency/Abstract and implement the checkDependency() function, the JavaScript version of IFormFieldDependency::checkDependency().

    All of the JavaScript dependency objects automatically register themselves during initialization with the WoltLabSuite/Core/Form/Builder/Field/Dependency/Manager which takes care of checking the dependencies at the correct points in time.

    Additionally, the dependency manager also ensures that form containers in which all children are hidden due to dependencies are also hidden and, once any child becomes available again, makes the container also available again. Every form container has to create a matching form container dependency object from a module based on WoltLabSuite/Core/Form/Builder/Field/Dependency/Abstract.

    WoltLab Suite includes a powerful way of creating forms: Form Builder. Form builder allows you to easily define all the fields and their constraints and interdependencies within PHP with full IDE support. It will then automatically generate the necessary HTML with full interactivity to render all the fields and also validate the fields\u2019 contents upon submission.

    The migration guide for WoltLab Suite Core 5.2 provides some examples of how to migrate existing forms to form builder that can also help in understanding form builder if the old way of creating forms is familiar.

    "},{"location":"php/api/form_builder/overview/#form-builder-components","title":"Form Builder Components","text":"

    Form builder consists of several components that are presented on the following pages:

    1. Structure of form builder
    2. Form validation and form data
    3. Form node dependencies

    In general, form builder provides default implementation of interfaces by providing either abstract classes or traits. It is expected that the interfaces are always implemented using these abstract classes and traits! This way, if new methods are added to the interfaces, default implementations can be provided by the abstract classes and traits without causing backwards compatibility problems.

    "},{"location":"php/api/form_builder/overview/#abstractformbuilderform","title":"AbstractFormBuilderForm","text":"

    To make using form builder easier, AbstractFormBuilderForm extends AbstractForm and provides most of the code needed to set up a form (of course without specific fields, those have to be added by the concrete form class), like reading and validating form values and using a database object action to use the form data to create or update a database object.

    In addition to the existing methods inherited by AbstractForm, AbstractFormBuilderForm provides the following methods:

    Additionally, between steps 1 and 2 and after step 3, the method provides two events, createForm and buildForm to allow plugins to register event listeners to execute additional code at the right point in time. - createForm() creates the FormDocument object and sets the form mode. Classes extending AbstractFormBuilderForm have to override this method (and call parent::createForm() as the first line in the overridden method) to add concrete form containers and form fields to the bare form document. - finalizeForm() is called after the form has been built and the complete form hierarchy has been established. This method should be overridden to add dependencies, for example. - setFormAction() is called at the end of readData() and sets the form document\u2019s action based on the controller class name and whether an object is currently edited. - If an object is edited, at the beginning of readData(), setFormObjectData() is called which calls IFormDocument::loadValuesFromObject(). If values need to be loaded from additional sources, this method should be used for that.

    AbstractFormBuilderForm also provides the following (public) properties:

    "},{"location":"php/api/form_builder/overview/#dialogformdocument","title":"DialogFormDocument","text":"

    Form builder forms can also be used in dialogs. For such forms, DialogFormDocument should be used which provides the additional methods cancelable($cancelable = true) and isCancelable() to set and check if the dialog can be canceled. If a dialog form can be canceled, a cancel button is added.

    If the dialog form is fetched via an AJAX request, IFormDocument::ajax() has to be called. AJAX forms are registered with WoltLabSuite/Core/Form/Builder/Manager which also supports getting all of the data of a form via the getData(formId) function. The getData() function relies on all form fields creating and registering a WoltLabSuite/Core/Form/Builder/Field/Field object that provides the data of a specific field.

    To make it as easy as possible to work with AJAX forms in dialogs, WoltLabSuite/Core/Form/Builder/Dialog (abbreviated as FormBuilderDialog from now on) should generally be used instead of WoltLabSuite/Core/Form/Builder/Manager directly. The constructor of FormBuilderDialog expects the following parameters:

    The three public functions of FormBuilderDialog are:

    Example:

    require(['WoltLabSuite/Core/Form/Builder/Dialog'], function(FormBuilderDialog) {\nvar dialog = new FormBuilderDialog(\n'testDialog',\n'wcf\\\\data\\\\test\\\\TestAction',\n'getDialog',\n{\ndestroyOnClose: true,\ndialog: {\ntitle: 'Test Dialog'\n},\nsubmitActionName: 'saveDialog'\n}\n);\n\nelById('testDialogButton').addEventListener('click', function() {\ndialog.open();\n});\n});\n
    "},{"location":"php/api/form_builder/structure/","title":"Structure of Form Builder","text":"

    Forms built with form builder consist of three major structural elements listed from top to bottom:

    1. form document,
    2. form container,
    3. form field.

    The basis for all three elements are form nodes.

    The form builder API uses fluent interfaces heavily, meaning that unless a method is a getter, it generally returns the objects itself to support method chaining.

    "},{"location":"php/api/form_builder/structure/#form-nodes","title":"Form Nodes","text":""},{"location":"php/api/form_builder/structure/#iformnode","title":"IFormNode","text":"

    IFormNode is the base interface that any node of a form has to implement and it requires the following methods:

    The following aspects are important when working with availability:

    Availability sets the static availability for form nodes that does not change during the lifetime of a form. In contrast, dependencies represent a dynamic availability for form nodes that depends on the current value of certain form fields. - cleanup() is called after the whole form is not used anymore to reset other APIs if the form fields depends on them and they expect such a reset. This method is not intended to clean up the form field\u2019s value as a new form document object is created to show a clean form. - getDocument() returns the IFormDocument object the node belongs to. (As IFormDocument extends IFormNode, form document objects simply return themselves.) - getHtml() returns the HTML representation of the node. getHtmlVariables() return template variables (in addition to the form node itself) to render the node\u2019s HTML representation. - id($id) and getId() set and get the id of the form node. Every id has to be unique within a form. getPrefixedId() returns the prefixed version of the node\u2019s id (see IFormDocument::getPrefix() and IFormDocument::prefix()). static validateId($id) is used to check if a given id is valid. - populate() is called by IFormDocument::build() after all form nodes have been added. This method should finilize the initialization of the form node after all parent-child relations of the form document have been established. This method is needed because during the construction of a form node, it neither knows the form document it will belong to nor does it know its parent. - validate() checks, after the form is submitted, if the form node is valid. A form node with children is valid if all of its child nodes are valid. A form field is valid if its value is valid. - static create($id) is the factory method that has to be used to create new form nodes with the given id.

    TFormNode provides a default implementation of most of these methods.

    A form container object represents a container for other form containers or form field directly. Every form container has to implement the IFormContainer interface which requires the following method:

    2. TabMenuFormContainer represents the container of tab menu, while
    3. TabFormContainer represents a tab of a tab menu and

    The methods of the interfaces that FormContainer is implementing are well documented, but here is a short overview of the most important methods when setting up a form or extending a form with an event listener:

    "},{"location":"php/api/form_builder/structure/#form-field","title":"Form Field","text":"

    A form field object represents a concrete form field that allows entering data. Every form field has to implement the IFormField interface which extends IFormChildNode and IFormElement.

    IFormField requires the following additional methods:

    The object property allows having different fields (requiring different ids) that represent the same object property which is handy when available options of the field\u2019s value depend on another field. Having object property allows to define different fields for each value of the other field and to use form field dependencies to only show the appropriate field. - readValue() reads the form field value from the request data after the form is submitted. - required($required = true) and isRequired() can be used to determine if the form field has to be filled out. By default, form fields do not have to be filled out. - value($value) and getSaveValue() can be used to get and set the value of the form field to be used outside of the context of forms. getValue(), in contrast, returns the internal representation of the form field\u2019s value. In general, the internal representation is only relevant when validating the value in additional validators. loadValue(array $data, IStorableObject $object) extracts the form field value from the given data array (and additional, non-editable data from the object if the field needs them).

    AbstractFormField provides default implementations of many of the listed methods above and should be extended instead of implementing IFormField directly.

    In addition to intrinsic validations like checking the length of the value of a text form field, in many cases, there are additional constraints specific to the form like ensuring that the text is not already used by a different object of the same database object class.

    As mentioned above, the data in the data sub-array is intended to directly create or update the database object with.

Thus, this data cannot be returned by IFormField::getSaveValue() so that IFormField::hasSaveValue() returns false and the form field\u2019s data is not collected by the standard DefaultFormDataProcessor object.

    Instead, such form fields register a CustomFormDataProcessor in their IFormField::populate() method that inserts the form field value into the $parameters array directly. This way, the relevant database object action method has access to the data to save it appropriately.

    The constructor of CustomFormDataProcessor requires an id (that is primarily used in error messages during the validation of the second parameter) and callables for IFormDataProcessor::processFormData() and IFormDataProcessor::processObjectData() which are passed the same parameters as the IFormDataProcessor methods. Only one of the callables has to be given, the other one then defaults to simply returning the relevant array unchanged.

When the data processor is invoked, it checks whether the relevant entry in the $parameters array exists and voids it by removing it from the array.

    As the first step, we have to model the people we want to manage with this package. As this is only an introductory tutorial, we will keep things simple and only consider the first and last name of a person. Thus, the database table we will store the people in only contains three columns:

    1. personID is the unique numeric identifier of each person created,
    2. firstName contains the first name of the person,
    3. lastName contains the last name of the person.

    As WoltLab Suite Core already provides a powerful default implementation of a sortable page, our work here is minimal:

    1. We need to set the active ACP menu item via the $activeMenuItem.
    2. $neededPermissions contains a list of permissions of which the user needs to have at least one in order to see the person list. We use the same permission for both the menu item and the page.
    3. The database object list class whose name is provided via $objectListClassName and that handles fetching the people from database is the PersonList class, which we have already created.
    4. To validate the sort field passed with the request, we set $validSortFields to the available database table columns.

    We will go piece by piece through the template code:

    1. We include the header template and set the page title wcf.acp.person.list. You have to include this template for every page!
    2. We set the content header and additional provide a button to create a new person in the content header navigation.
    3. As not all people are listed on the same page if many people have been created, we need a pagination for which we use the pages template plugin. The {hascontent}{content}{/content}{/hascontent} construct ensures the .paginationTop element is only shown if the pages template plugin has a return value, thus if a pagination is necessary.
    4. Now comes the main part of the page, the list of the people, which will only be displayed if any people exist. Otherwise, an info box is displayed using the generic wcf.global.noItems language item. The $objects template variable is automatically assigned by wcf\\page\\MultipleLinkPage and contains the PersonList object used to read the people from database. The table itself consists of a thead and a tbody element and is extendable with more columns using the template events columnHeads and columns. In general, every table should provide these events. The default structure of a table is used here so that the first column of the content rows contains icons to edit and to delete the row (and provides another standard event rowButtons) and that the second column contains the ID of the person. The table can be sorted by clicking on the head of each column. The used variables $sortField and $sortOrder are automatically assigned to the template by SortablePage.
    5. The .contentFooter element is only shown if people exist as it basically repeats the .contentHeaderNavigation and .paginationTop element.
    6. The delete button for each person shown in the .columnIcon element relies on the global WoltLabSuite/Core/Ui/Object/Action module which only requires the jsObjectActionContainer CSS class in combination with the data-object-action-class-name attribute for the table element, the jsObjectActionObject CSS class for each person's tr element in combination with the data-object-id attribute, and lastly the delete button itself, which is created with the objectAction template plugin.
    7. The .jsReloadPageWhenEmpty CSS class on the tbody element ensures that once all persons on the page have been deleted, the page is reloaded.
    8. Lastly, the footer template is included that terminates the page. You also have to include this template for every page!

    Now, we have finished the page to manage the people so that we can move on to the forms with which we actually create and edit the people.

    Like the person list, the form to add new people requires a controller class and a template.

    The properties here consist of three types: the \u201chousekeeping\u201d properties $activeMenuItem and $neededPermissions, which fulfill the same roles as for PersonListPage, and the $objectEditLinkController property, which is used to generate a link to edit the newly created person after submitting the form, and finally $formAction and $objectActionClass required by the PHP form builder API used to generate the form.

    Because of using form builder, we only have to set up the two form fields for entering the first and last name, respectively:

    1. Each field is a simple single-line text field, thus we use TextFormField.
    2. The parameter of the create() method expects the id of the field/name of the database object property, which is firstName and lastName, respectively, here.
    3. The language item of the label shown in the ouput above the input field is set via the label() method.
    4. As both fields have to be filled out, required() is called, and the maximum length is set via maximumLength().
    5. Lastly, to make it easier to fill out the form more quickly, the first field is auto-focused by calling autoFocus().

    We will now only concentrate on the new parts compared to personList.tpl:

    1. We use the $action variable to distinguish between the languages items used for adding a person and for creating a person.
    2. Because of form builder, we only have to call {@$form->getHtml()} to generate all relevant output for the form.

    As mentioned before, for the form to edit existing people, we only need a new controller as the template has already been implemented in a way that it handles both, adding and editing.

    In general, edit forms extend the associated add form so that the code to read and to validate the input data is simply inherited.

    After setting a different active menu item, we have to change the value of $formAction because this form, in contrast to PersonAddForm, does not create but update existing persons.

    As we rely on form builder, the only thing necessary in this controller is to read and validate the edit object, i.e. the edited person, which is done in readParameters().

    For the front end, that means the part with which the visitors of a website interact, we want to implement a simple sortable page that lists the people. This page should also be directly linked in the main menu.

    As in the ACP, we need a controller and a template. You might notice that both the controller\u2019s (unqualified) class name and the template name are the same for the ACP and the front end.

    This class is almost identical to the ACP version. In the front end, we do not need to set the active menu item manually because the system determines the active menu item automatically based on the requested page. Furthermore, $neededPermissions has not been set because in the front end, users do not need any special permission to access the page. In the front end, we explicitly set the $defaultSortField so that the people listed on the page are sorted by their last name (in ascending order) by default.

    If you compare this template to the one used in the ACP, you will recognize similar elements like the .paginationTop element, the p.info element if no people exist, and the .contentFooter element.

    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/userGroupOption.xsd\">\n<import>\n<options>\n<option name=\"admin.content.canManagePeople\">\n<categoryname>admin.content</categoryname>\n<optiontype>boolean</optiontype>\n<defaultvalue>0</defaultvalue>\n<admindefaultvalue>1</admindefaultvalue>\n<usersonly>1</usersonly>\n</option>\n</options>\n</import>\n</data>\n

    We use the existing admin.content user group option category for the permission as the people are \u201ccontent\u201d (similar the the ACP menu item). As the permission is for administrators only, we set defaultvalue to 0 and admindefaultvalue to 1. This permission is only relevant for registered users so that it should not be visible when editing the guest user group. This is achieved by setting usersonly to 1.

    As this is a package for WoltLab Suite Core 3, we need to require it using <requiredpackage>. We require the latest version (when writing this tutorial) 5.4.0 Alpha 1. Additionally, we disallow installation of the package in the next major version 6.0 by excluding the 6.0.0 Alpha 1 version.

    The most important part are to installation instructions. First, we install the ACP templates, files and templates, create the database table and import the language item. Afterwards, the ACP menu items and the permission are added. Now comes the part of the instructions where the order of the instructions is crucial: In menuItem.xml, we refer to the com.woltlab.wcf.people.PersonList page that is delivered by page.xml. As the menu item package installation plugin validates the given page and throws an exception if the page does not exist, we need to install the page before the menu item!

    This concludes the first part of our tutorial series after which you now have a working simple package with which you can manage people in the ACP and show the visitors of your website a simple list of all created people in the front end.

    The complete source code of this part can be found on GitHub.

    The existing model of a person only contains the person\u2019s first name and their last name (in additional to the id used to identify created people). To add the birthday to the model, we need to create an additional database table column using the database package installation plugin:

    files/acp/database/install_com.woltlab.wcf.people.birthday.php 
    <?php\n\nuse wcf\\system\\database\\table\\column\\DateDatabaseTableColumn;\nuse wcf\\system\\database\\table\\PartialDatabaseTable;\n\nreturn [\nPartialDatabaseTable::create('wcf1_person')\n->columns([\nDateDatabaseTableColumn::create('birthday'),\n]),\n];\n

    If we have a Person object, this new property can be accessed the same way as the personID property, the firstName property, or the lastName property from the base package: $person->birthday.

    in eventListener.xml, see below.

    As BirthdayPersonAddFormListener extends AbstractEventListener and as the name of relevant event is createForm, AbstractEventListener internally automatically calls onCreateForm() with the event object as the parameter. It is important to set <inherit>1</inherit> so that the event listener is also executed for PersonEditForm, which extends PersonAddForm.

    The language item wcf.person.birthday used in the label is the only new one for this package:

    language/de.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<language xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/language.xsd\" languagecode=\"de\">\n<category name=\"wcf.person\">\n<item name=\"wcf.person.birthday\"><![CDATA[Geburtstag]]></item>\n</category>\n</language>\n

    "},{"location":"tutorial/series/part_2/#adding-birthday-table-column-in-acp","title":"Adding Birthday Table Column in ACP","text":"

    To add a birthday column to the person list page in the ACP, we need three parts:

    1. an event listener that makes the birthday database table column a valid sort field,
    2. a template listener that adds the birthday column to the table\u2019s head, and
    3. a template listener that adds the birthday column to the table\u2019s rows.

    The first part is a very simple class:

    files/lib/system/event/listener/BirthdaySortFieldPersonListPageListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\nuse wcf\\page\\SortablePage;\n\n/**\n * Makes people's birthday a valid sort field in the ACP and the front end.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class BirthdaySortFieldPersonListPageListener extends AbstractEventListener\n{\n    /**\n     * @see SortablePage::validateSortField()\n     */\n    public function onValidateSortField(SortablePage $page): void\n    {\n        $page->validSortFields[] = 'birthday';\n    }\n}\n

    We use SortablePage as a type hint instead of wcf\\acp\\page\\PersonListPage because we will be using the same event listener class in the front end to also allow sorting that list by birthday.

    As the relevant template codes are only one line each, we will simply put them directly in the templateListener.xml file that will be shown later on. The code for the table head is similar to the other th elements:

    <th class=\"columnDate columnBirthday{if $sortField == 'birthday'} active {$sortOrder}{/if}\"><a href=\"{link controller='PersonList'}pageNo={@$pageNo}&sortField=birthday&sortOrder={if $sortField == 'birthday' && $sortOrder == 'ASC'}DESC{else}ASC{/if}{/link}\">{lang}wcf.person.birthday{/lang}</a></th>\n

    For the table body\u2019s column, we need to make sure that the birthday is only show if it is actually set:

    <td class=\"columnDate columnBirthday\">{if $person->birthday}{@$person->birthday|strtotime|date}{/if}</td>\n
    "},{"location":"tutorial/series/part_2/#adding-birthday-in-front-end","title":"Adding Birthday in Front End","text":"

    In the front end, we also want to make the list sortable by birthday and show the birthday as part of each person\u2019s \u201cstatistics\u201d.

    To add the birthday as a valid sort field, we use BirthdaySortFieldPersonListPageListener just as in the ACP. In the front end, we will now use a template (__personListBirthdaySortField.tpl) instead of a directly putting the template code in the templateListener.xml file:

    templates/__personListBirthdaySortField.tpl 
    <option value=\"birthday\"{if $sortField == 'birthday'} selected{/if}>{lang}wcf.person.birthday{/lang}</option>\n

    You might have noticed the two underscores at the beginning of the template file. For templates that are included via template listeners, this is the naming convention we use.

    Putting the template code into a file has the advantage that in the administrator is able to edit the code directly via a custom template group, even though in this case this might not be very probable.

    To show the birthday, we use the following template code for the personStatistics template event, which again makes sure that the birthday is only shown if it is actually set:

    templates/__personListBirthday.tpl 
    {if $person->birthday}\n    <dt>{lang}wcf.person.birthday{/lang}</dt>\n    <dd>{@$person->birthday|strtotime|date}</dd>\n{/if}\n

    To reduce the number of database queries when different APIs require person objects, we implement a runtime cache for people:

    "},{"location":"tutorial/series/part_3/#comments","title":"Comments","text":"

    To allow users to comment on people, we need to tell the system that people support comments. This is done by registering a com.woltlab.wcf.comment.commentableContent object type whose processor implements ICommentManager:

    objectType.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/objectType.xsd\">\n<import>\n<type>\n<name>com.woltlab.wcf.person.personComment</name>\n<definitionname>com.woltlab.wcf.comment.commentableContent</definitionname>\n<classname>wcf\\system\\comment\\manager\\PersonCommentManager</classname>\n</type>\n</import>\n</data>\n

    Additionally, we have added a new enableComments database table column to the wcf1_person database table whose value can be set when creating or editing a person in the ACP. With this option, comments on individual people can be disabled.

    Liking comments is already built-in and only requires some extra code in the PersonPage class for showing the likes of pre-loaded comments.

    The PersonPage class is similar to the PersonEditForm in the ACP in that it reads the id of the requested person from the request data and validates the id in readParameters(). The rest of the code only handles fetching the list of comments on the requested person. In readData(), this list is fetched using CommentHandler::getCommentList() if comments are enabled for the person. The assignVariables() method assigns some additional template variables like $commentCanAdd, which is 1 if the active person can add comments and is 0 otherwise, $lastCommentTime, which contains the UNIX timestamp of the last comment, and $likeData, which contains data related to the likes for the disabled comments.

    For now, the person template is still very empty and only shows the comments in the content area. The template code shown for comments is very generic and used in this form in many locations as it only sets the header of the comment list and the container ul#personCommentList element for the comments shown by commentList template. The ul#personCommentList elements has five additional data- attributes required by the JavaScript API for comments for loading more comments or creating new ones. The commentListAddComment template adds the WYSIWYG support. The attribute wysiwygSelector should be the id of the comment list personCommentList with an additional AddComment suffix.

    The page.xml file has been extended for the new person page with identifier com.woltlab.wcf.people.Person. Compared to the pre-existing com.woltlab.wcf.people.PersonList page, there are four differences:

    1. It has a <handler> element with a class name as value. This aspect will be discussed in more detail in the next section.
    2. There are no <content> elements because, both, the title and the content of the page are dynamically generated in the template.
    3. The <requireObjectID> tells the system that this page requires an object id to properly work, in this case a valid person id.
    4. This page has a <parent> page, the person list page. In general, the details page for any type of object that is listed on a different page has the list page as its parent.

    Like any page handler, the PersonPageHandler class has to implement the IMenuPageHandler interface, which should be done by extending the AbstractMenuPageHandler class. As we want administrators to link to specific people in menus, for example, we have to also implement the ILookupPageHandler interface by extending the AbstractLookupPageHandler class.

    For the ILookupPageHandler interface, we need to implement three methods:

    1. getLink($objectID) returns the link to the person page with the given id. In this case, we simply delegate this method call to the Person object returned by PersonRuntimeCache::getObject().
    2. isValid($objectID) returns true if the person with the given id exists, otherwise false. Here, we use PersonRuntimeCache::getObject() again and check if the return value is null, which is the case for non-existing people.
    3. lookup($searchString) is used when setting up an internal link and when searching for the linked person. This method simply searches the first and last name of the people and returns an array with the person data. While the link, the objectID, and the title element are self-explanatory, the image element can either contain an HTML <img> tag, which is displayed next to the search result (WoltLab Suite uses an image tag for users showing their avatar, for example), or a FontAwesome icon class (starting with fa-).

    Additionally, the class also implements IOnlineLocationPageHandler which is used to determine the online location of users. To ensure upwards-compatibility if the IOnlineLocationPageHandler interface changes, the TOnlineLocationPageHandler trait is used. The IOnlineLocationPageHandler interface requires two methods to be implemented:

    1. getOnlineLocation(Page $page, UserOnline $user) returns the textual description of the online location. The language item for the user online locations should use the pattern wcf.page.onlineLocation.{page identifier}.
    2. prepareOnlineLocation(Page $page, UserOnline $user) is called for each user online before the getOnlineLocation() calls. In this case, calling prepareOnlineLocation() first enables us to add all relevant person ids to the person runtime cache so that for all getOnlineLocation() calls combined, only one database query is necessary to fetch all person objects.

    This concludes the third part of our tutorial series after which each person has a dedicated page on which people can comment on the person.

    In addition to static boxes with fixed contents, administrators are able to create dynamic boxes with contents from the database. In our case here, we want administrators to be able to create boxes listing people. To do so, we first have to register a new object type for this person list box controller for the object type definition com.woltlab.wcf.boxController:

    <type>\n<name>com.woltlab.wcf.personList</name>\n<definitionname>com.woltlab.wcf.boxController</definitionname>\n<classname>wcf\\system\\box\\PersonListBoxController</classname>\n</type>\n

    The com.woltlab.wcf.boxController object type definition requires the provided class to implement wcf\\system\\box\\IBoxController:

    files/lib/system/box/PersonListBoxController.class.php 
    <?php\n\nnamespace wcf\\system\\box;\n\nuse wcf\\data\\person\\PersonList;\nuse wcf\\system\\WCF;\n\n/**\n * Dynamic box controller implementation for a list of persons.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Box\n */\nfinal class PersonListBoxController extends AbstractDatabaseObjectListBoxController\n{\n    /**\n     * @inheritDoc\n     */\n    protected $conditionDefinition = 'com.woltlab.wcf.box.personList.condition';\n\n    /**\n     * @inheritDoc\n     */\n    public $defaultLimit = 5;\n\n    /**\n     * @inheritDoc\n     */\n    protected $sortFieldLanguageItemPrefix = 'wcf.person';\n\n    /**\n     * @inheritDoc\n     */\n    protected static $supportedPositions = [\n        'sidebarLeft',\n        'sidebarRight',\n    ];\n\n    /**\n     * @inheritDoc\n     */\n    public $validSortFields = [\n        'firstName',\n        'lastName',\n        'comments',\n    ];\n\n    /**\n     * @inheritDoc\n     */\n    protected function getObjectList()\n    {\n        return new PersonList();\n    }\n\n    /**\n     * @inheritDoc\n     */\n    protected function getTemplate()\n    {\n        return WCF::getTPL()->fetch('boxPersonList', 'wcf', [\n            'boxPersonList' => $this->objectList,\n            'boxSortField' => $this->sortField,\n            'boxPosition' => $this->box->position,\n        ], true);\n    }\n}\n

    By extending AbstractDatabaseObjectListBoxController, we only have to provide minimal data ourself and rely mostly on the default implementation provided by AbstractDatabaseObjectListBoxController:

    1. As we will support conditions for the listed people, we have to set the relevant condition definition via $conditionDefinition.
    2. AbstractDatabaseObjectListBoxController already supports restricting the number of listed objects. To do so, you only have to specify the default number of listed objects via $defaultLimit.
    3. AbstractDatabaseObjectListBoxController also supports setting the sort order of the listed objects. You have to provide the supported sort fields via $validSortFields and specify the prefix used for the language items of the sort fields via $sortFieldLanguageItemPrefix so that for every $validSortField in $validSortFields, the language item {$sortFieldLanguageItemPrefix}.{$validSortField} must exist.
    4. The box system supports different positions. Each box controller specifies the positions it supports via $supportedPositions. To keep the implementation simple here as different positions might require different output in the template, we restrict ourselves to sidebars.
    5. getObjectList() returns an instance of DatabaseObjectList that is used to read the listed objects. getObjectList() itself must not call readObjects(), as AbstractDatabaseObjectListBoxController takes care of calling the method after adding the conditions and setting the sort order.
    6. getTemplate() returns the contents of the box relying on the boxPersonList template here:
    templates/boxPersonList.tpl 
    <ul class=\"sidebarItemList\">\n{foreach from=$boxPersonList item=boxPerson}\n        <li class=\"box24\">\n            <span class=\"icon icon24 fa-user\"></span>\n\n            <div class=\"sidebarItemTitle\">\n                <h3>{anchor object=$boxPerson}</h3>\n{capture assign='__boxPersonDescription'}{lang __optional=true}wcf.person.boxList.description.{$boxSortField}{/lang}{/capture}\n{if $__boxPersonDescription}\n                    <small>{@$__boxPersonDescription}</small>\n{/if}\n            </div>\n        </li>\n{/foreach}\n</ul>\n

    The template relies on a .sidebarItemList element, which is generally used for sidebar listings. (If different box positions were supported, we either have to generate different output by considering the value of $boxPosition in the template or by using different templates in getTemplate().) One specific piece of code is the $__boxPersonDescription variable, which supports an optional description below the person's name relying on the optional language item wcf.person.boxList.description.{$boxSortField}. We only add one such language item when sorting the people by comments: In such a case, the number of comments will be shown. (When sorting by first and last name, there are no additional useful information that could be shown here, though the plugin from part 2 adding support for birthdays might also show the birthday when sorting by first or last name.)

    Lastly, we also provide the language item wcf.acp.box.boxController.com.woltlab.wcf.personList, which is used in the list of available box controllers.

    "},{"location":"tutorial/series/part_4/#conditions","title":"Conditions","text":"

    The condition system can be used to generally filter a list of objects. In our case, the box system supports conditions to filter the objects shown in a specific box. Admittedly, our current person implementation only contains minimal data so that filtering might not make the most sense here but it will still show how to use the condition system for boxes. We will support filtering the people by their first and last name so that, for example, a box can be created listing all people with a specific first name.

    The first step for condition support is to register a object type definition for the relevant conditions requiring the IObjectListCondition interface:

    objectTypeDefinition.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/objectTypeDefinition.xsd\">\n<import>\n<definition>\n<name>com.woltlab.wcf.box.personList.condition</name>\n<interfacename>wcf\\system\\condition\\IObjectListCondition</interfacename>\n</definition>\n</import>\n</data>\n

    Next, we register the specific conditions for filtering by the first and last name using this object type condition:

    <type>\n<name>com.woltlab.wcf.people.firstName</name>\n<definitionname>com.woltlab.wcf.box.personList.condition</definitionname>\n<classname>wcf\\system\\condition\\person\\PersonFirstNameTextPropertyCondition</classname>\n</type>\n<type>\n<name>com.woltlab.wcf.people.lastName</name>\n<definitionname>com.woltlab.wcf.box.personList.condition</definitionname>\n<classname>wcf\\system\\condition\\person\\PersonLastNameTextPropertyCondition</classname>\n</type>\n

    PersonFirstNameTextPropertyCondition and PersonLastNameTextPropertyCondition only differ minimally so that we only focus on PersonFirstNameTextPropertyCondition here, which relies on the default implementation AbstractObjectTextPropertyCondition and only requires specifying different object properties:

    files/lib/system/condition/person/PersonFirstNameTextPropertyCondition.class.php 
    <?php\n\nnamespace wcf\\system\\condition\\person;\n\nuse wcf\\data\\person\\Person;\nuse wcf\\system\\condition\\AbstractObjectTextPropertyCondition;\n\n/**\n * Condition implementation for the first name of a person.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license WoltLab License <http://www.woltlab.com/license-agreement.html>\n * @package WoltLabSuite\\Core\\System\\Condition\n */\nfinal class PersonFirstNameTextPropertyCondition extends AbstractObjectTextPropertyCondition\n{\n    /**\n     * @inheritDoc\n     */\n    protected $className = Person::class;\n\n    /**\n     * @inheritDoc\n     */\n    protected $description = 'wcf.person.condition.firstName.description';\n\n    /**\n     * @inheritDoc\n     */\n    protected $fieldName = 'personFirstName';\n\n    /**\n     * @inheritDoc\n     */\n    protected $label = 'wcf.person.firstName';\n\n    /**\n     * @inheritDoc\n     */\n    protected $propertyName = 'firstName';\n\n    /**\n     * @inheritDoc\n     */\n    protected $supportsMultipleValues = true;\n}\n
    1. $className contains the class name of the relevant database object from which the class name of the database object list is derived and $propertyName is the name of the database object's property that contains the value used for filtering.
    2. By setting $supportsMultipleValues to true, multiple comma-separated values can be specified so that, for example, a box can also only list people with either of two specific first names.
    3. $description (optional), $fieldName, and $label are used in the output of the form field.

    (The implementation here is specific for AbstractObjectTextPropertyCondition. The wcf\\system\\condition namespace also contains several other default condition implementations.)

    PersonInformation provides two methods, canDelete() and canEdit(), to check whether the active user can delete or edit a specific piece of information. In both cases, it is checked if the current user has created the relevant piece of information to check the user-specific permissions or to fall back to the moderator-specific permissions.

    There also two getter methods for the person, the piece of information belongs to (getPerson()), and for the user profile of the user who created the information (getUserProfile()). In both cases, we use runtime caches, though in getUserProfile(), we also have to consider the case of the user who created the information being deleted, i.e. userID being null. For such a case, we also save the name of the user who created the information in username, so that we can return a guest user profile object in this case. The most interesting method is getFormattedInformation(), which returns the HTML code of the information text meant for output. To generate such an output, HtmlOutputProcessor::process() is used and here is where we first use the associated message object type com.woltlab.wcf.people.information mentioned before.

    To keep things simple here, we reuse the structure and CSS classes used for comments. Additionally, we always list all pieces of information. If there are many pieces of information, a nicer solution would be a pagination or loading more pieces of information with JavaScript.

    First, we note the jsObjectActionContainer class in combination with the data-object-action-class-name attribute, which are needed for the delete button for each piece of information, as explained here. In PersonInformationAction, we have overridden the default implementations of validateDelete() and delete() which are called after clicking on a delete button. In validateDelete(), we call PersonInformation::canDelete() on all pieces of information to be deleted for proper permission validation, and in delete(), we update the informationCount values of the people the deleted pieces of information belong to (see below).

    The button to add a new piece of information, #personInformationAddButton, and the buttons to edit existing pieces of information, .jsEditInformation, are controlled with JavaScript code initialized at the very end of the template.

    Lastly, in create() we provide default values for the time, userID, username, and ipAddress for cases like here when creating a new piece of information, where do not explicitly provide this data. Additionally, we extract the information text from the information_htmlInputProcessor parameter provided by the associated WYSIWYG form field and update the number of pieces of information created for the relevant person.

    To create new pieces of information or editing existing ones, we do not add new form controllers but instead use dialogs generated by the form builder API so that the user does not have to leave the person page.

    When clicking on the add button or on any of the edit buttons, a dialog opens with the relevant form:

    We use the WoltLabSuite/Core/Form/Builder/Dialog module, which takes care of the internal handling with regard to these dialogs. We only have to provide some data during for initializing these objects and call the open() function after a button has been clicked.

    Explanation of the initialization arguments for WoltLabSuite/Core/Form/Builder/Dialog used here:

    Next, we focus on PersonInformationAction, which actually provides the contents of these dialogs and creates and edits the information:

    When setting up the WoltLabSuite/Core/Form/Builder/Dialog object for adding new pieces of information, we specified getAddDialog and submitAddDialog as the names of the dialog getter and submit handler. In addition to these two methods, the matching validation methods validateGetAddDialog() and validateGetAddDialog() are also added. As the forms for adding and editing pieces of information have the same structure, this form is created in buildDialog() using a DialogFormDocument object, which is intended for forms in dialogs. We fire an event in buildDialog() so that plugins are able to easily extend the dialog with additional data.

    validateGetAddDialog() checks if the user has the permission to create new pieces of information and if a valid id for the person, the information will belong to, is given. The method configured in the WoltLabSuite/Core/Form/Builder/Dialog object returning the dialog is expected to return two values: the id of the form (formId) and the contents of form shown in the dialog (dialog). This data is returned by getAddDialog using the dialog build previously by buildDialog().

    After the form is submitted, validateSubmitAddDialog() has to do the same basic validation as validateGetAddDialog() so that validateGetAddDialog() is simply called. Additionally, the form data is read and validated. In submitAddDialog(), we first check if there have been any validation errors: If any error occured during validation, we return the same data as in getAddDialog() so that the dialog is shown again with the erroneous fields marked as such. Otherwise, if the validation succeeded, the form data is used to create the new piece of information. In addition to the form data, we manually add the id of the person to whom the information belongs to. Lastly, we could return some data that we could access in the JavaScript callback function after successfully submitting the dialog. As we will simply be reloading the page, no such data is returned. An alternative to reloading to the page would be dynamically inserting the new piece of information in the list so that we would have to return the rendered list item for the new piece of information.

    The process for getting and submitting the dialog to edit existing pieces of information is similar to the process for adding new pieces of information. Instead of the id of the person, however, we now pass the id of the edited piece of information and in submitEditDialog(), we update the edited information instead of creating a new one like in submitAddDialog(). After editing a piece of information, we do not reload the page but dynamically update the text of the information in the TypeScript code so that we return the updated rendered information text and id of the edited pieced of information in submitAddDialog().

    As we store the name of the user who create a new piece of information and store their IP address, we have to add event listeners to properly handle the following scenarios:

    1. If the user is renamed, the value of username stored with the person information has to be updated, which can be achieved by a simple event listener that only has to specify the name of relevant database table if AbstractUserActionRenameListener is extended:
    files/lib/system/event/listener/PersonUserActionRenameListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\n/**\n * Updates person information during user renaming.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonUserActionRenameListener extends AbstractUserActionRenameListener\n{\n    /**\n     * @inheritDoc\n     */\n    protected $databaseTables = [\n        'wcf{WCF_N}_person_information',\n    ];\n}\n
    1. If users are merged, all pieces of information need to be assigned to the target user of the merging. Again, we only have to specify the name of relevant database table if AbstractUserMergeListener is extended:
    files/lib/system/event/listener/PersonUserMergeListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\n/**\n * Updates person information during user merging.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonUserMergeListener extends AbstractUserMergeListener\n{\n    /**\n     * @inheritDoc\n     */\n    protected $databaseTables = [\n        'wcf{WCF_N}_person_information',\n    ];\n}\n
    1. If the option to prune stored ip addresses after a certain period of time is enabled, we also have to prune them in the person information database table. Here we also only have to specify the name of the relevant database table and provide the mapping from the ipAddress column to the time column:
    files/lib/system/event/listener/PersonPruneIpAddressesCronjobListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\nuse wcf\\system\\cronjob\\PruneIpAddressesCronjob;\n\n/**\n * Prunes old ip addresses.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonPruneIpAddressesCronjobListener extends AbstractEventListener\n{\n    protected function onExecute(PruneIpAddressesCronjob $cronjob): void\n    {\n        $cronjob->columns['wcf' . WCF_N . '_person_information']['ipAddress'] = 'time';\n    }\n}\n
    1. The ip addresses in the person information database table also have to be considered for the user data export which can also be done with minimal effort by providing the name of the relevant database table:
    files/lib/system/event/listener/PersonUserExportGdprListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\nuse wcf\\acp\\action\\UserExportGdprAction;\n\n/**\n * Adds the ip addresses stored with the person information during user data export.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonUserExportGdprListener extends AbstractEventListener\n{\n    protected function onExport(UserExportGdprAction $action): void\n    {\n        $action->ipAddresses['com.woltlab.wcf.people'] = ['wcf' . WCF_N . '_person_information'];\n    }\n}\n

    Lastly, we present the updated eventListener.xml file with new entries for all of these event listeners:

    eventListener.xml

    "},{"location":"tutorial/series/part_6/#user-activity-points","title":"User Activity Points","text":"

    The first step to support activity points is to register an object type for the com.woltlab.wcf.user.activityPointEvent object type definition for created person information and specify the default number of points awarded per piece of information:

    objectType.xml
    <type>\n<name>com.woltlab.wcf.people.information</name>\n<definitionname>com.woltlab.wcf.user.activityPointEvent</definitionname>\n<points>2</points>\n</type>\n

    Additionally, the phrase wcf.user.activityPoint.objectType.com.woltlab.wcf.people.information (in general: wcf.user.activityPoint.objectType.{objectType}) has to be added.

    The activity points are awarded when new pieces are created via PersonInformation::create() using UserActivityPointHandler::fireEvent() and removed in PersonInformation::create() via UserActivityPointHandler::removeEvents() if pieces of information are deleted.

    Lastly, we have to add two components for updating data: First, we register a new rebuild data worker

    objectType.xml
    <type>\n<name>com.woltlab.wcf.people.information</name>\n<definitionname>com.woltlab.wcf.rebuildData</definitionname>\n<classname>wcf\\system\\worker\\PersonInformationRebuildDataWorker</classname>\n</type>\n

    which updates the number of instances for which any user received person information activity points. (This data worker also requires the phrases wcf.acp.rebuildData.com.woltlab.wcf.people.information and wcf.acp.rebuildData.com.woltlab.wcf.people.information.description).

    Second, we add an event listener for UserActivityPointItemsRebuildDataWorker to update the total user activity points awarded for person information:

    PersonInformationUserActivityEvent::prepare() must check for all events whether the associated piece of information still exists and if it is the case, mark the event as accessible via the setIsAccessible() method, set the title of the activity event via setTitle(), and set a description of the event via setDescription() for which we use the newly added PersonInformation::getFormattedExcerpt() method.

    Lastly, we have to add the phrase wcf.user.recentActivity.com.woltlab.wcf.people.information, which is shown in the list of activity events as the type of activity event.

    SCSS is a scripting language that features a syntax similar to CSS and compiles into native CSS at runtime. It provides many great additions to CSS such as declaration nesting and variables, it is recommended to read the official guide to learn more.

    You can create .scss files containing only pure CSS code and it will work just fine, you are at no point required to write actual SCSS code.

    Media breakpoints instruct the browser to apply different CSS depending on the viewport dimensions, e.g. serving a desktop PC a different view than when viewed on a smartphone.

    WoltLab Suite\u2019s SCSS compiler supports adding preloading metadata to the CSS. To communicate the preloading intent to the compiler, the --woltlab-suite-preload CSS variable is set to the result of the preload() function:

    .fooBar {\n--woltlab-suite-preload:    #{preload(\n'#{$style_image_path}custom/background.png',\n$as: \"image\",\n$crossorigin: false,\n$type: \"image/png\"\n)};\n\nbackground: url('#{$style_image_path}custom/background.png');\n}\n

    The parameters of the preload() function map directly to the preloading properties that are used within the <link> tag and the link: HTTP response header.

    The above example will result in a <link> similar to the following being added to the generated HTML:

    <link rel=\"preload\" href=\"https://example.com/images/style-1/custom/background.png\" as=\"image\" type=\"image/png\">\n

    Use preloading sparingly for the most important resources where you can be certain that the browser will need them. Unused preloaded resources will unnecessarily waste bandwidth.

    The anchor template plugin creates a HTML elements. The easiest way to use the template plugin is to pass it an instance of ITitledLinkObject:

    {anchor object=$object}\n

    generates the same output as

    <a href=\"{$object->getLink()}\">{$object->getTitle()}</a>\n

    Instead of an object parameter, a link and content parameter can be used:

    {anchor link=$linkObject content=$content}\n

    where $linkObject implements ILinkableObject and $content is either an object implementing ITitledObject or having a __toString() method or $content is a string or a number.

    The last special attribute is append whose contents are appended to the href attribute of the generated anchor element.

    All of the other attributes matching ~^[a-z]+([A-z]+)+$~, expect for href which is disallowed, are added as attributes to the anchor element.

    If an object attribute is present, the object also implements IPopoverObject and if the return value of IPopoverObject::getPopoverLinkClass() is included in the class attribute of the anchor tag, data-object-id is automatically added. This functionality makes it easy to generate links with popover support. Instead of

    <a href=\"{$entry->getLink()}\" class=\"blogEntryLink\" data-object-id=\"{$entry->entryID}\">{$entry->subject}</a>\n

    using

    {anchor object=$entry class='blogEntryLink'}\n

    is sufficient if Entry::getPopoverLinkClass() returns blogEntryLink.

    In many cases, conditional statements can be used to determine if a certain section of a template is shown:

    {if $foo === 'bar'}\n    only shown if $foo is bar\n{/if}\n

    In some situations, however, such conditional statements are not sufficient. One prominent example is a template event:

    {if $foo === 'bar'}\n    <ul>\n{if $foo === 'bar'}\n            <li>Bar</li>\n{/if}\n\n{event name='listItems'}\n    </li>\n{/if}\n

    In this example, if $foo !== 'bar', the list will not be shown, regardless of the additional template code provided by template listeners. In such a situation, hascontent has to be used:

    {hascontent}\n    <ul>\n{content}\n{if $foo === 'bar'}\n                <li>Bar</li>\n{/if}\n\n{event name='listItems'}\n{/content}\n    </ul>\n{/hascontent}\n

    If the part of the template wrapped in the content tags has any (trimmed) content, the part of the template wrapped by hascontent tags is shown (including the part wrapped by the content tags), otherwise nothing is shown. Thus, this construct avoids an empty list compared to the if solution above.

    Templates are responsible for the output a user sees when requesting a page (while the PHP code is responsible for providing the data that will be shown). Templates are text files with .tpl as the file extension. WoltLab Suite Core compiles the template files once into a PHP file that is executed when a user requests the page. In subsequent request, as the PHP file containing the compiled template already exists, compiling the template is not necessary anymore.

    "},{"location":"view/templates/#template-types-and-conventions","title":"Template Types and Conventions","text":"

    WoltLab Suite Core supports two types of templates: frontend templates (or simply templates) and backend templates (ACP templates). Each type of template is only available in its respective domain, thus frontend templates cannot be included or used in the ACP and vice versa.

    For pages and forms, the name of the template matches the unqualified name of the PHP class except for the Page or Form suffix:

    If you follow this convention, WoltLab Suite Core will automatically determine the template name so that you do not have to explicitly set it.

    For forms that handle creating and editing objects, in general, there are two form classes: FooAddForm and FooEditForm. WoltLab Suite Core, however, generally only uses one template fooAdd.tpl and the template variable $action to distinguish between creating a new object ($action = 'add') and editing an existing object ($action = 'edit') as the differences between templates for adding and editing an object are minimal.

    The next step is to create the PHP class which will serve our page:

    4. Within the directory page, please create the file TestPage.class.php

    Copy and paste the following code into the TestPage.class.php:

    The class inherits from wcf\\page\\AbstractPage, the default implementation of pages without form controls. It defines quite a few methods that will be automatically invoked in a specific order, for example readParameters() before readData() and finally assignVariables() to pass arbitrary values to the template.

    The property $greet is defined as World, but can optionally be populated through a GET variable (index.php?test/&greet=You would output Hello You!). This extra code illustrates the separation of data processing that takes place within all sort of pages, where all user-supplied data is read from within a single method. It helps organizing the code, but most of all it enforces a clean class logic that does not start reading user input at random places, including the risk to only escape the input of variable $_GET['foo'] 4 out of 5 times.

    Reading and processing the data is only half the story, now we need a template to display the actual content for our page. You don't need to specify it yourself, it will be automatically guessed based on your namespace and class name, you can read more about it later.

    Last but not least, you must not include the closing PHP tag ?> at the end, it can cause PHP to break on whitespaces and is not required at all.

    Templates are a mixture of HTML and Smarty-like template scripting to overcome the static nature of raw HTML. The above code will display the phrase Hello World! in the application frame, just as any other page would render. The included templates header and footer are responsible for the majority of the overall page functionality, but offer a whole lot of customization abilities to influence their behavior and appearance.

    Both files and templates are archive-based package components, that deploy their payload using tar archives rather than adding the raw files to the package file. Please create the archive files.tar and add the contents of the files/* directory, but not the directory files/ itself. Repeat the same process for the templates directory, but this time with the file name templates.tar. Place both files in the root of your project.

    Last but not least, create the package archive com.example.test.tar and add all the files listed below.

    The developer tools provide an interface to synchronize the data of an installed package with a bare repository on the local disk. You can re-import most PIPs at any time and have the changes applied without crafting a manual update. This process simulates a regular package update with a single PIP only, and resets the cache after the import has been completed.

    Projects require the absolute path to the package directory, that is, the directory where it can find the package.xml. It is not required to install an package to register it as a project, but you have to install it in order to work with it. It does not install the package by itself!

    There is a special button on the project list that allows for a mass-import of projects based on a search path. Each direct child directory of the provided path will be tested and projects created this way will use the identifier extracted from the package.xml.

    "},{"location":"getting-started/#synchronizing","title":"Synchronizing","text":"

    The install instructions in the package.xml are ignored when offering the PIP imports, the detection works entirely based on the default filename for each PIP. On top of that, only PIPs that implement the interface wcf\\system\\devtools\\pip\\IIdempotentPackageInstallationPlugin are valid for import, as it indicates that importing the PIP multiple times will have no side-effects and that the result is deterministic regardless of the number of times it has been imported.

    Some built-in PIPs, such as sql or script, do not qualify for this step and remain unavailable at all times. However, you can still craft and perform an actual package update to have these PIPs executed.

    The purpose of confirmation dialogs is to prevent misclicks and to inform the user of potential consequences of their action. A confirmation dialog should always ask a concise question that includes a reference to the object the action is performed upon.

    You can exclude extra information or form elements in confirmation dialogs, but these should be kept as compact as possible.

    Confirmation dialogs are a special type that use the role=\"alertdialog\" attribute and will always include a cancel button. The dialog itself will be limited to a width of 500px, the title can wrap into multiple lines and there will be no \u201cX\u201d button to close the dialog.

    "},{"location":"javascript/components_confirmation/#when-to-use","title":"When to Use","text":"

    Over the past few years the term \u201cConfirmation Fatique\u201d has emerged that describes the issue of having too many confirmation dialogs even there is no real need for them. A confirmation dialog should only be displayed when the action requires further inputs, for example, a soft delete that requires a reason, or when the action is destructive.

    "},{"location":"javascript/components_confirmation/#proper-wording","title":"Proper Wording","text":"

    The confirmation question should hint the severity of the action, in particular whether or not it is destructive. Destructive actions are those that cannot be undone and either cause a permanent mutation or that cause data loss. All questions should be phrased in one or two ways depending on the action.

    Destructive action:

    Are you sure you want to delete \u201cExample Object\u201d? (German) Wollen Sie \u201eBeispiel-Objekt\u201c wirklich l\u00f6schen?

    WoltLab Suite 6.0 currently ships with three presets for common confirmation dialogs.

    Modal dialogs are a powerful tool to draw the viewer\u2019s attention to an important message, question or form. Dialogs naturally interrupt the workflow and prevent the navigation to other sections by making other elements on the page inert.

    WoltLab Suite 6.0 ships with four different types of dialogs.

    "},{"location":"javascript/components_dialog/#quickstart","title":"Quickstart","text":"

    There are four different types of dialogs that each fulfill their own specialized role and that provide built-in features to make the development much easier. Please see the following list to make a quick decision of what kind of dialog you need.

    "},{"location":"javascript/components_dialog/#dialogs-without-controls","title":"Dialogs Without Controls","text":"

    Dialogs may contain just an explanation or extra information that should be presented to the viewer without requiring any further interaction. The dialog can be closed via the \u201cX\u201d button or by clicking the modal backdrop.

    const dialog = dialogFactory().fromHtml(\"<p>Hello World</p>\").withoutControls();\ndialog.show(\"Greetings from my dialog\");\n
    "},{"location":"javascript/components_dialog/#when-to-use","title":"When to Use","text":"

    The short answer is: Don\u2019t.

    Dialogs without controls are an anti-pattern because they only contain content that does not require the modal appearance of a dialog. More often than not dialogs are used for this kind of content because they are easy to use without thinking about better ways to present the content.

    If possible these dialogs should be avoided and the content is presented in a more suitable way, for example, as a flyout or by showing content on an existing or new page.

    "},{"location":"javascript/components_dialog/#alerts","title":"Alerts","text":"

    Alerts are designed to inform the user of something important that requires no further action by the user. Typical examples for alerts are error messages or warnings.

    An alert will only provide a single button to acknowledge the dialog and must not contain interactive content. The dialog itself will be limited to a width of 500px, the title can wrap into multiple lines and there will be no \u201cX\u201d button to close the dialog.

    const dialog = dialogFactory()\n.fromHtml(\"<p>ERROR: Something went wrong!</p>\")\n.asAlert();\ndialog.show(\"Server Error\");\n

    You can customize the label of the primary button to better explain what will happen next. This can be useful for alerts that will have a side-effect when closing the dialog, such as redirect to a different page.

    const dialog = dialogFactory()\n.fromHtml(\"<p>Something went wrong, we cannot find your shopping cart.</p>\")\n.asAlert({\nprimary: \"Back to the Store Page\",\n});\n\ndialog.addEventListener(\"primary\", () => {\nwindow.location.href = \"https://example.com/shop/\";\n});\n\ndialog.show(\"The shopping cart is missing\");\n

    The primary event is triggered both by clicking on the primary button and by clicks on the modal backdrop.

    "},{"location":"javascript/components_dialog/#when-to-use_1","title":"When to Use","text":"

    Alerts are a special type of dialog that use the role=\"alert\" attribute to signal its importance to assistive tools. Use alerts sparingly when there is no other way to communicate that something did not work as expected.

    Alerts should not be used for cases where you expect an error to happen. For example, a form control that expectes an input to fall within a restricted range should show an inline error message instead of raising an alert.

    "},{"location":"javascript/components_dialog/#confirmation","title":"Confirmation","text":"

    Confirmation dialogs are supported through a separate factory function that provides a set of presets as well as a generic API. Please see the separate documentation for confirmation dialogs to learn more.

    "},{"location":"javascript/components_dialog/#prompts","title":"Prompts","text":"

    The most common type of dialogs are prompts that are similar to confirmation dialogs, but without the restrictions and with a regular title. These dialogs can be used universally and provide a submit and cancel button by default.

    In addition they offer an \u201cextra\u201d button that is placed to the left of the default buttons are can be used to offer a single additional action. A possible use case for an \u201cextra\u201d button would be a dialog that includes an instance of the WYSIWYG editor, the extra button could be used to trigger a message preview.

    "},{"location":"javascript/general-usage/#the-history-of-the-legacy-api","title":"The History of the Legacy API","text":"

    The WoltLab Suite 3.0 introduced a new API based on AMD-Modules with ES5-JavaScript that was designed with high performance and visible dependencies in mind. This was a fundamental change in comparison to the legacy API that was build many years before while jQuery was still a thing and we had to deal with ancient browsers such as Internet Explorer 9 that felt short in both CSS and JavaScript capabilities.

    Fast forward a few years, the old API is still around and most important, it is actively being used by some components that have not been rewritten yet. This has been done to preserve the backwards-compatibility and to avoid the significant amount of work that it requires to rewrite a component. The components invoked on page initialization have all been rewritten to use the modern API, but some deferred objects that are invoked later during the page runtime may still use the old API.

    However, the legacy API is deprecated and you should not rely on it for new components at all. It slowly but steadily gets replaced up until a point where its last bits are finally removed from the code base.

    "},{"location":"javascript/general-usage/#embedding-javascript-inside-templates","title":"Embedding JavaScript inside Templates","text":"

    The <script>-tags are extracted and moved during template processing, eventually placing them at the very end of the body element while preserving their order of appearance.

    This behavior is controlled through the data-relocate=\"true\" attribute on the <script> which is mandatory for almost all scripts, mostly because their dependencies (such as jQuery) are moved to the bottom anyway.

    <script data-relocate=\"true\">\n$(function() {\n// Code that uses jQuery (Legacy API)\n});\n</script>\n\n<!-- or -->\n\n<script data-relocate=\"true\">\nrequire([\"Some\", \"Dependencies\"], function(Some, Dependencies) {\n// Modern API\n});\n</script>\n

    Your JavaScript files may change over time and you would want the users' browsers to always load and use the latest version of your files. This can be achieved by appending the special LAST_UPDATE_TIME constant to your file path. It contains the unix timestamp of the last time any package was installed, updated or removed and thus avoid outdated caches by relying on a unique value, without invalidating the cache more often that it needs to be.

    <script data-relocate=\"true\" src=\"{$__wcf->getPath('app')}js/App.js?t={@LAST_UPDATE_TIME}\"></script>\n

    For small scripts you can simply serve the full, non-minified version to the user at all times, the differences in size and execution speed are insignificant and are very unlikely to offer any benefits. They might even yield a worse performance, because you'll have to include them statically in the template, even if the code is never called.

    However, if you're including a minified build in your app or plugin, you should include a switch to load the uncompressed version in the debug mode, while serving the minified and optimized file to the average visitor. You should use the ENABLE_DEBUG_MODE constant to decide which version should be loaded.

    The legacy JavaScript API is the original code that was part of the 2.x series of WoltLab Suite, formerly known as WoltLab Community Framework. It has been superseded for the most part by the ES5/AMD-modules API introduced with WoltLab Suite 3.0.

    Some parts still exist to this day for backwards-compatibility and because some less important components have not been rewritten yet. The old API is still supported, but marked as deprecated and will continue to be replaced parts by part in future releases, up until their entire removal, including jQuery support.

    WoltLab Suite 5.5 introduces a new API for Ajax requests that uses Promises to control the code flow. It does not rely on references to existing objects and does not use arbitrary callbacks to handle the setup and handling of the request.

    The lazy initialization is performed upon the first invocation from the callee, using the magic _ajaxSetup() method to retrieve the basic configuration for this and any future requests.

    The data returned by _ajaxSetup() is cached and the data will be used to pre-populate the request data before sending it. The callee can overwrite any of these properties. It is intended to reduce the overhead when issuing request when these requests share the same properties, such as accessing the same endpoint.

    Typical use-cases include input field with suggestions, where possible values are requested from the server, but the input changed faster than the server was able to reply.

    The new JavaScript-API was introduced with WoltLab Suite 3.0 and was a major change in all regards. The previously used API heavily relied on larger JavaScript files that contained a lot of different components with hidden dependencies and suffered from extensive jQuery usage for historic reasons.

    Eventually a new API was designed that solves the issues with the legacy API by following a few basic principles: 1. Vanilla ES5-JavaScript. It allows us to achieve the best performance across all platforms, there is simply no reason to use jQuery today and the performance penalty on mobile devices is a real issue. 2. Strict usage of modules. Each component is placed in an own file and all dependencies are explicitly declared and injected at the top.Eventually we settled with AMD-style modules using require.js which offers both lazy loading and \"ahead of time\"-compilatio with r.js. 3. No jQuery-based components on page init. Nothing is more annoying than loading a page and then wait for JavaScript to modify the page before it becomes usable, forcing the user to sit and wait. Heavily optimized vanilla JavaScript components offered the speed we wanted. 4. Limited backwards-compatibility. The new API should make it easy to update existing components by providing similar interfaces, while still allowing legacy code to run side-by-side for best compatibility and to avoid rewritting everything from the start.

    To consume the types of WoltLab Suite, you will need to install the @woltlab/wcf npm package using a git URL that refers to the appropriate branch of WoltLab/WCF.

    A full package.json that includes WoltLab Suite, TypeScript, eslint and Prettier could look like the following.

    package.json 
    {\n\"devDependencies\": {\n\"@typescript-eslint/eslint-plugin\": \"^5.51.0\",\n\"@typescript-eslint/parser\": \"^5.51.0\",\n\"eslint\": \"^8.33.0\",\n\"eslint-config-prettier\": \"^8.6.0\",\n\"prettier\": \"^2.8.4\",\n\"typescript\": \"^4.9.5\"\n},\n\"dependencies\": {\n\"@woltlab/d.ts\": \"https://github.com/WoltLab/d.ts.git#4040fc083245edeb2f8832d4613b9e76aa9c17a5\"\n}\n}\n

    After installing the types using npm, you will also need to configure tsconfig.json to take the types into account. To do so, you will need to add them to the compilerOptions.paths option. A complete tsconfig.json file that matches the configuration of WoltLab Suite could look like the following.

    tsconfig.json 
    {\n\"include\": [\n\"node_modules/@woltlab/d.ts/global.d.ts\",\n\"ts/**/*\"\n],\n\"compilerOptions\": {\n\"target\": \"ES2022\",\n\"module\": \"amd\",\n\"rootDir\": \"ts/\",\n\"outDir\": \"files/js/\",\n\"lib\": [\n\"DOM\",\n\"DOM.Iterable\",\n\"ES2022\"\n],\n\"strictNullChecks\": true,\n\"moduleResolution\": \"node\",\n\"esModuleInterop\": true,\n\"noImplicitThis\": true,\n\"strictBindCallApply\": true,\n\"baseUrl\": \".\",\n\"paths\": {\n\"*\": [\n\"node_modules/@woltlab/d.ts/*\"\n]\n},\n\"importHelpers\": true,\n\"newLine\": \"lf\"\n}\n}\n

    After this initial set-up, you would place your TypeScript source files into the ts/ folder of your project. The generated JavaScript target files will be placed into files/js/ and thus will be installed by the file PIP.

    To update the TypeScript types, the commit hash in package.json needs to be updated to an appropriate commit in the d.ts repository and npm install needs to be rerun.

    After completing this initial set-up you can start writing your first TypeScript module. The TypeScript compiler can be launched in Watch Mode by running npx tsc -w.

    WoltLab Suite\u2019s modules can be imported using the standard ECMAScript module import syntax by specifying the full module name. The public API of the module can also be exported using the standard ECMAScript module export syntax.

    ts/Example.ts 
    import * as Language from \"WoltLabSuite/Core/Language\";\n\nexport function run() {\nalert(Language.get(\"wcf.foo.bar\"));\n}\n

    The new tiny builds are highly optimized variants of existing JavaScript files and modules, aiming for significant performance improvements for guests and search engines alike. This is accomplished by heavily restricting page interaction to read-only actions whenever possible, which in return removes the need to provide certain JavaScript modules in general.

    For example, disallowing guests to write any formatted messages will in return remove the need to provide the WYSIWYG editor at all. But it doesn't stop there, there are a lot of other modules that provide additional features for the editor, and by excluding the editor, we can also exclude these modules too.

    Long story short, the tiny mode guarantees that certain actions will never be carried out by guests or search engines, therefore some modules are not going to be needed by them ever.

    The errorMessage property in the returned response object for failed AJAX requests contained an exception-specific but still highly generic error message. This issue has been around for quite a long time and countless of implementations are relying on this false behavior, eventually forcing us to leave the value unchanged.

    This problem is solved by adding the new property realErrorMessage that exposes the message exactly as it was provided and now matches the value that would be displayed to users in traditional forms.

    "},{"location":"migration/wsc30/javascript/#example-code","title":"Example Code","text":"

    "},{"location":"migration/wsc30/javascript/#simplified-form-submit-in-dialogs","title":"Simplified Form Submit in Dialogs","text":"

    Forms embedded in dialogs often do not contain the HTML <form>-element and instead rely on JavaScript click- and key-handlers to emulate a <form>-like submit behavior. This has spawned a great amount of nearly identical implementations that all aim to handle the form submit through the Enter-key, still leaving some dialogs behind.

    WoltLab Suite 3.1 offers automatic form submit that is enabled through a set of specific conditions and data attributes:

    1. There must be a submit button that matches the selector .formSubmit > input[type=\"submit\"], .formSubmit > button[data-type=\"submit\"].
    2. The dialog object provided to UiDialog.open() implements the method _dialogSubmit().
    3. Input fields require the attribute data-dialog-submit-on-enter=\"true\" to be set, the type must be one of number, password, search, tel, text or url.

    Clicking on the submit button or pressing the Enter-key in any watched input field will start the submit process. This is done automatically and does not require a manual interaction in your code, therefore you should not bind any click listeners on the submit button yourself.

    Any input field with the required attribute set will be validated to contain a non-empty string after processing the value with String.prototype.trim(). An empty field will abort the submit process and display a visible error message next to the offending field.

    "},{"location":"migration/wsc30/javascript/#helper-function-for-inline-error-messages","title":"Helper Function for Inline Error Messages","text":"

    Displaying inline error messages on-the-fly required quite a few DOM operations that were quite simple but also super repetitive and thus error-prone when incorrectly copied over. The global helper function elInnerError() was added to provide a simple and consistent behavior of inline error messages.

    You can display an error message by invoking elInnerError(elementRef, \"Your Error Message\"), it will insert a new <small class=\"innerError\"> and sets the given message. If there is already an inner error present, then the message will be replaced instead.

    Hiding messages is done by setting the 2nd parameter to false or an empty string:

    The special values null and undefined are supported too, but their usage is discouraged, because they make it harder to understand the intention by reading the code:

    There's another feature that allows all matching PIPs to be executed in a row using a single button click. In order to solve dependencies on other PIPs, any implementing PIP must also provide the method getSyncDependencies() that returns the dependent PIPs in an arbitrary order.

    Updating the template is easy as the complete form is replace by a single line of code:

    acptemplates/personAdd.tpl 
    {include file='header' pageTitle='wcf.acp.person.'|concat:$action}\n\n<header class=\"contentHeader\">\n    <div class=\"contentHeaderTitle\">\n        <h1 class=\"contentTitle\">{lang}wcf.acp.person.{$action}{/lang}</h1>\n    </div>\n\n    <nav class=\"contentHeaderNavigation\">\n        <ul>\n            <li><a href=\"{link controller='PersonList'}{/link}\" class=\"button\"><span class=\"icon icon16 fa-list\"></span> <span>{lang}wcf.acp.menu.link.person.list{/lang}</span></a></li>\n\n{event name='contentHeaderNavigation'}\n        </ul>\n    </nav>\n</header>\n\n{@$form->getHtml()}\n\n{include file='footer'}\n

    PersonEditForm also becomes much simpler: only the edited Person object must be read:

    files/lib/acp/form/PersonEditForm.class.php 
    <?php\nnamespace wcf\\acp\\form;\nuse wcf\\data\\person\\Person;\nuse wcf\\system\\exception\\IllegalLinkException;\n\n/**\n * Shows the form to edit an existing person.\n * \n * @author  Matthias Schmidt\n * @copyright   2001-2019 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\Acp\\Form\n */\nclass PersonEditForm extends PersonAddForm {\n    /**\n     * @inheritDoc\n     */\n    public $activeMenuItem = 'wcf.acp.menu.link.person';\n\n    /**\n     * @inheritDoc\n     */\n    public function readParameters() {\n        parent::readParameters();\n\n        if (isset($_REQUEST['id'])) {\n            $this->formObject = new Person(intval($_REQUEST['id']));\n            if (!$this->formObject->personID) {\n                throw new IllegalLinkException();\n            }\n        }\n    }\n}\n

    Most of the work is done in PersonAddForm:

    But, as you can see, the number of lines almost decreased by half. All changes are due to extending AbstractFormBuilderForm:

    With version 5.2 of WoltLab Suite Core the like system was completely replaced by the new reactions system. This makes it necessary to make some adjustments to existing code so that your plugin integrates completely into the new system. However, we have kept these adjustments as small as possible so that it is possible to use the reaction system with slight restrictions even without adjustments.

    "},{"location":"migration/wsc31/like/#limitations-if-no-adjustments-are-made-to-the-existing-code","title":"Limitations if no adjustments are made to the existing code","text":"

    Since there are no more likes with the new version, it makes no sense to send notifications about it. Instead of notifications about likes, notifications about reactions are now sent. However, this only changes the notification text and not the notification itself. To update the notification, we first add the interface \\wcf\\data\\reaction\\object\\IReactionObject to the \\wcf\\data\\like\\object\\ILikeObject object (e.g. in WoltLab Suite Forum we added the interface to the class \\wbb\\data\\post\\LikeablePost). After that the object is marked as \"compatible with WoltLab Suite Core 5.2\" and notifications about reactions are sent again.

    "},{"location":"migration/wsc31/like/#language-variables","title":"Language Variables","text":"

    Next, to display all reactions for the current notification in the notification text, we include the trait \\wcf\\system\\user\\notification\\event\\TReactionUserNotificationEvent in the user notification event class (typically named like *LikeUserNotificationEvent). These trait provides a new function that reads out and groups the reactions. The result of this function must now only be passed to the language variable. The name \"reactions\" is typically used as the variable name for the language variable.

    As a final step, we only need to change the language variables themselves. To ensure a consistent usability, the same formulations should be used as in the WoltLab Suite Core.

    To adjust entries in the Recent Activity, only three small steps are necessary. First we pass the concrete reaction to the language variable, so that we can use the reaction object there. To do this, we add the following variable to the text of the \\wcf\\system\\user\\activity\\event\\IUserActivityEvent object: $event->reactionType. Typically we name the variable reactionType. In the second step, we mark the event as compatible. Therefore we set the parameter supportsReactions in the objectType.xml to 1. So for example the entry looks like this:

    objectType.xml
    <type>\n<name>com.woltlab.example.likeableObject.recentActivityEvent</name>\n<definitionname>com.woltlab.wcf.user.recentActivityEvent</definitionname>\n<classname>wcf\\system\\user\\activity\\event\\LikeableObjectUserActivityEvent</classname>\n<supportsReactions>1</supportsReactions>\n</type>\n

    "},{"location":"migration/wsc31/php/#php-class","title":"PHP Class","text":"

    First, we create the PHP class that provides our interface to provide the data. The class must implement interface wcf\\system\\user\\content\\provider\\IUserContentProvider in any case. Mostly we process data which is based on wcf\\data\\DatabaseObject. In this case, the WoltLab Suite provides an abstract class wcf\\system\\user\\content\\provider\\AbstractDatabaseUserContentProvider that can be used to automatically generates the standardized classes to generate the list and deletes objects via the DatabaseObjectAction. For example, if we would create a content provider for comments, the class would look like this:

    files/lib/system/user/content/provider/CommentUserContentProvider.class.php
    <?php\nnamespace wcf\\system\\user\\content\\provider;\nuse wcf\\data\\comment\\Comment;\n\n/**\n * User content provider for comments.\n *\n * @author  Joshua Ruesweg\n * @copyright   2001-2018 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\User\\Content\\Provider\n * @since   5.2\n */\nclass CommentUserContentProvider extends AbstractDatabaseUserContentProvider {\n    /**\n     * @inheritdoc\n     */\n    public static function getDatabaseObjectClass() {\n        return Comment::class;\n    }\n}\n

    Now the appropriate object type must be created for the class. This object type must be from the definition com.woltlab.wcf.content.userContentProvider and include the previous created class as FQN in the parameter classname. Also the following parameters can be used in the object type:

    It is recommended by search engines to mark up links within user generated content using the rel=\"ugc\" attribute to indicate that they might be less trustworthy or spammy.

    WoltLab Suite 5.3 will automatically sets that attribute on external links during message output processing. Set the new HtmlOutputProcessor::$enableUgc property to false if the type of message is not user-generated content, but restricted to a set of trustworthy users. An example of such a type of message would be official news articles.

    If you manually generate links based off user input you need to specify the attribute yourself. The $isUgc attribute was added to StringUtil::getAnchorTag(string, string, bool, bool): string, allowing you to easily generate a correct anchor tag.

    If you need to specify additional HTML attributes for the anchor tag you can use the new StringUtil::getAnchorTagAttributes(string, bool): string method to generate the anchor attributes that are dependent on the target URL. Specifically the attributes returned are the class=\"externalURL\" attribute, the rel=\"\u2026\" attribute and the target=\"\u2026\" attribute.

    It was discovered that the code holds references to scaled image resources for an unnecessarily long time, taking up memory. This becomes especially apparent when multiple images are scaled within a loop, reusing the same variable name for consecutive images. Unless the destination variable is explicitely cleared before processing the next image up to two images will be stored in memory concurrently. This possibly causes the request to exceed the memory limit or ImageMagick's internal resource limits, even if sufficient resources would have been available to scale the current image.

    Starting with WoltLab Suite 5.3 it is recommended to clear image handles as early as possible. The usual pattern of creating a thumbnail for an existing image would then look like this:

    <?php\nforeach ([ 200, 500 ] as $size) {\n    $adapter = ImageHandler::getInstance()->getAdapter();\n    $adapter->loadFile($src);\n    $thumbnail = $adapter->createThumbnail(\n        $size,\n        $size,\n        true\n    );\n    $adapter->writeImage($thumbnail, $destination);\n    // New: Clear thumbnail as soon as possible to free up the memory.\n    $thumbnail = null;\n}\n

    WCF.Action.Delete and WCF.Action.Toggle were used for buttons to delete or enable/disable objects via JavaScript. In each template, WCF.Action.Delete or WCF.Action.Toggle instances had to be manually created for each object listing.

    With version 5.4 of WoltLab Suite, we have added a CSS selector-based global TypeScript module that only requires specific CSS classes to be added to the HTML structure for these buttons to work. Additionally, we have added a new {objectAction} template plugin, which generates these buttons reducing the amount of boilerplate template code.

    The required base HTML structure is as follows:

    1. A .jsObjectActionContainer element with a data-object-action-class-name attribute that contains the name of PHP class that executes the actions.
    2. .jsObjectActionObject elements within .jsObjectActionContainer that represent the objects for which actions can be executed. Each .jsObjectActionObject element must have a data-object-id attribute with the id of the object.
    3. .jsObjectAction elements within .jsObjectActionObject for each action with a data-object-action attribute with the name of the action. These elements can be generated with the {objectAction} template plugin for the delete and toggle action.

    Example:

    <table class=\"table jsObjectActionContainer\" {*\n    *}data-object-action-class-name=\"wcf\\data\\foo\\FooAction\">\n    <thead>\n        <tr>\n{* \u2026 *}\n        </tr>\n    </thead>\n\n    <tbody>\n{foreach from=$objects item=foo}\n            <tr class=\"jsObjectActionObject\" data-object-id=\"{$foo->getObjectID()}\">\n                <td class=\"columnIcon\">\n{objectAction action=\"toggle\" isDisabled=$foo->isDisabled}\n{objectAction action=\"delete\" objectTitle=$foo->getTitle()}\n{* \u2026 *}\n                </td>\n{* \u2026 *}\n            </tr>\n{/foreach}\n    </tbody>\n</table>\n

    Please refer to the documentation in ObjectActionFunctionTemplatePlugin for details and examples on how to use this template plugin.

    The relevant TypeScript module registering the event listeners on the object action buttons is Ui/Object/Action. When an action button is clicked, an AJAX request is sent using the PHP class name and action name. After the successful execution of the action, the page is either reloaded if the action button has a data-object-action-success=\"reload\" attribute or an event using the EventHandler module is fired using WoltLabSuite/Core/Ui/Object/Action as the identifier and the object action name. Ui/Object/Action/Delete and Ui/Object/Action/Toggle listen to these events and update the user interface depending on the execute action by removing the object or updating the toggle button, respectively.

    Converting from WCF.Action.* to the new approach requires minimal changes per template, as shown in the relevant pull request #4080.

As a TypeScript-based replacement for WCF.Table.EmptyTableHandler that is only initialized once globally, WoltLabSuite/Core/Ui/Empty was added. To use this new module, you only have to add the CSS class jsReloadPageWhenEmpty to the relevant HTML element. Once this HTML element no longer has child elements, the page is reloaded. To also cover scenarios in which there are fixed child elements that should not be considered when determining if there are no child elements, the data-reload-page-when-empty=\"ignore\" can be set for these elements.

With WoltLab Suite 5.4, we have added a general API that manages such rate limiting. Leveraging this API is easily done.

    1. Register an object type for the definition com.woltlab.wcf.floodControl: com.example.foo.myContent.

      FloodControl::getInstance()->registerContent('com.example.foo.myContent');\n
      You should only call this method if the user creates the content themselves. If the content is automatically created by the system, for example when copying / duplicating existing content, no activity should be registered.

    3. To check the last time when the active user created content of the relevant type, use 

      FloodControl::getInstance()->getLastTime('com.example.foo.myContent');\n
      If you want to limit the number of content items created within a certain period of time, for example within one day, use 
      $data = FloodControl::getInstance()->countContent('com.example.foo.myContent', new \\DateInterval('P1D'));\n// number of content items created within the last day\n$count = $data['count'];\n// timestamp when the earliest content item was created within the last day\n$earliestTime = $data['earliestTime'];\n
      The method also returns earliestTime so that you can tell the user in the error message when they are able again to create new content of the relevant type.

      Flood control entries are only stored for 31 days and older entries are cleaned up daily.

    The previously mentioned methods of FloodControl use the active user and the current timestamp as reference point. FloodControl also provides methods to register content or check flood control for other registered users or for guests via their IP address.

    "},{"location":"migration/wsc53/session/#reauthentication","title":"Reauthentication","text":"

    For security sensitive processing, you might want to ensure that the account owner is actually present instead of a third party accessing a session that was accidentally left logged in.

    WoltLab Suite 5.4 ships with a generic reauthentication framework. To request reauthentication within your controller you need to:

    1. Use the wcf\\system\\user\\authentication\\TReauthenticationCheck trait.
    2. Call: 
      $this->requestReauthentication(LinkHandler::getInstance()->getControllerLink(static::class, [\n /* additional parameters */\n]));\n

    requestReauthentication() will check if the user has recently authenticated themselves. If they did, the request proceeds as usual. Otherwise, they will be asked to reauthenticate themselves. After the successful authentication, they will be redirected to the URL that was passed as the first parameter (the current controller within the example).

    Details can be found in WoltLab/WCF#3775.

    "},{"location":"migration/wsc53/session/#multi-factor-authentication","title":"Multi-factor Authentication","text":"

    To implement multi-factor authentication securely, WoltLab Suite 5.4 implements the concept of a \u201cpending user change\u201d. The user will not be logged in (i.e. WCF::getUser()->userID returns null) until they authenticate themselves with their second factor.

    Requesting multi-factor authentication is done on an opt-in basis for compatibility reasons. If you perform authentication yourself and do not trust the authentication source to perform multi-factor authentication itself, you will need to adjust your logic to request multi-factor authentication from WoltLab Suite:

    Previously:

    WCF::getSession()->changeUser($targetUser);\n

    Now:

    $isPending = WCF::getSession()->changeUserAfterMultifactorAuthentication($targetUser);\nif ($isPending) {\n    // Redirect to the authentication form. The user will not be logged in.\n    // Note: Do not use `getControllerLink` to support both the frontend as well as the ACP.\n    HeaderUtil::redirect(LinkHandler::getInstance()->getLink('MultifactorAuthentication', [\n        'url' => /* Return To */,\n    ]));\n    exit;\n}\n// Proceed as usual. The user will be logged in.\n
    "},{"location":"migration/wsc53/session/#adding-multi-factor-methods","title":"Adding Multi-factor Methods","text":"

    Adding your own multi-factor method requires the implementation of a single object type:

    objectType.xml
    <type>\n<name>com.example.multifactor.foobar</name>\n<definitionname>com.woltlab.wcf.multifactor</definitionname>\n<icon><!-- Font Awesome 4 Icon Name goes here. --></icon>\n<priority><!-- Determines the sort order, higher priority will be preferred for authentication. --></priority>\n<classname>wcf\\system\\user\\multifactor\\FoobarMultifactorMethod</classname>\n</type>\n

    The given classname must implement the IMultifactorMethod interface.

    As a self-contained example, you can find the initial implementation of the email multi-factor method in WoltLab/WCF#3729. Please check the version history of the PHP class to make sure you do not miss important changes that were added later.

    Multi-factor authentication is security sensitive. Make sure to carefully read the remarks in IMultifactorMethod for possible issues. Also make sure to carefully test your implementation against all sorts of incorrect input and consider attack vectors such as race conditions. It is strongly recommended to generously check the current state by leveraging assertions and exceptions.

    Historically, events were tightly coupled with a single class, with the event object being an object of this class, expecting the event listener to consume public properties and method of the event object. The $parameters array was introduced due to limitations of this pattern, avoiding moving all the values that might be of interest to the event listener into the state of the object. Events were still tightly coupled with the class that fired the event and using the opaque parameters array prevented IDEs from assisting with autocompletion and typing.

    WoltLab Suite 5.5 introduces the concept of dedicated, reusable event classes. Any newly introduced event will receive a dedicated class, implementing the wcf\\system\\event\\IEvent interface. These event classes may be fired from multiple locations, making them reusable to convey that a conceptual action happened, instead of a specific class doing something. An example for using the new event system could be a user logging in: Instead of listening on a the login form being submitted and the Facebook login action successfully running, an event UserLoggedIn might be fired whenever a user logs in, no matter how the login is performed.

    Additionally, these dedicated event classes will benefit from full IDE support. All the relevant values may be stored as real properties on the event object.

    Event classes should not have an Event suffix and should be stored in an event namespace in a matching location. Thus, the UserLoggedIn example might have a FQCN of \\wcf\\system\\user\\authentication\\event\\UserLoggedIn.

    Event listeners for events implementing IEvent need to follow PSR-14, i.e. they need to be callable. In practice, this means that the event listener class needs to implement __invoke(). No interface has to be implemented in this case.

    $parameters = [\n    'value' => \\random_int(1, 1024),\n];\n\nEventHandler::getInstance()->fireAction($this, 'valueAvailable', $parameters);\n

    WoltLab/WCF#4275 added support for embedded objects like mentions for comments and comment responses. To properly render embedded objects whenever you are using comments in your packages, you have to use ViewableCommentList/ViewableCommentResponseList in these places or ViewableCommentRuntimeCache/ViewableCommentResponseRuntimeCache. While these runtime caches are only available since version 5.5, the viewable list classes have always been available so that changing CommentList to ViewableCommentList, for example, is a backwards-compatible change.

    WoltLab Suite 5.5 changes the factory classes for common configurations of database columns within the PHP-based DDL API to contain a private constructor, preventing object creation.

    This change affects the following classes:

    The static create() method never returned an object of the factory class, but instead in object of the base type (e.g. IntDatabaseTableColumn for NotNullInt10DatabaseTableColumn). Constructing an object of these factory classes is considered a bug, as the class name implies a specific column configuration, that might or might not hold if the object is modified afterwards.

    See WoltLab/WCF#4564 for details.

    WoltLab Suite 5.5 adds the IDefaultValueDatabaseTableColumn interface which is used to check whether specifying a default value is legal. For backwards compatibility this interface is implemented by AbstractDatabaseTableColumn. You should explicitly add this interface to custom table column type classes to avoid breakage if the interface is removed from AbstractDatabaseTableColumn in a future version. Likewise you should explicitly check for the interface before attempting to access the methods related to the default value of a column.

    In the past dialogs have been used for all kinds of purposes, for example, to provide more details. Dialogs make it incredibly easy to add extra information or forms to an existing page without giving much thought: A simple button is all that it takes to show a dialog.

    This has lead to an abundance of dialogs that have been used in a lot of places where dialogs are not the right choice, something we are guilty of in a lot of cases. A lot of research has gone into the accessibility of dialogs and the general recommendations towards their usage and the behavior.

    One big issue of dialogs have been their inconsistent appearance in terms of form buttons and their (lack of) keyboard support for input fields. WoltLab Suite 6.0 provides a completely redesigned API that strives to make the process of creating dialogs much easier and features a consistent keyboard support out of the box.

    "},{"location":"migration/wsc55/dialogs/#conceptual-changes","title":"Conceptual Changes","text":"

    Dialogs are a powerful tool, but as will all things, it is easy to go overboard and eventually one starts using dialogs out of convenience rather than necessity. In general dialogs should only be used when you need to provide information out of flow, for example, for urgent error messages.

    A common misuse that we are guilty of aswell is the use of dialogs to present content. Dialogs completely interrupt whatever the user is doing and can sometimes even hide contextual relevant content on the page. It is best to embed information into regular pages and either use deep links to refer to them or make use of flyovers to present the content in place.

    Another important change is the handling of form inputs. Previously it was required to manually craft the form submit buttons, handle button clicks and implement a proper validation. The new API provides the \u201cprompt\u201d type which implements all this for you and exposing JavaScript events to validate, submit and cancel the dialog.

    Last but not least there have been updates to the visual appearance of dialogs. The new dialogs mimic the appearance on modern desktop operating systems as well as smartphones by aligning the buttons to the bottom right. In addition the order of buttons has been changed to always show the primary button on the rightmost position. These changes were made in an effort to make it easier for users to adopt an already well known control concept and to improve the overall accessibility.

    The source of a dialog is provided directly through the fluent API of dialogFactory() which provides methods to spawn dialogs using elements, HTML strings or completely empty.

    This is the most awkward feature of the legacy dialog API: Poorly documented and cumbersome to use. Implementing it required a dedicated form submit button and the keyboard interaction required the data-dialog-submit-on-enter=\"true\" attribute to be set on all input elements that should submit the form through Enter.

    The new dialog API takes advantage of the form[method=\"dialog\"] functionality which behaves similar to regular forms but will signal the form submit to the surrounding dialog. As a developer you only need to listen for the validate and the primary event to implement your logic.

    const dialog = dialogFactory()\n.fromId(\"myComplexDialogWithFormInputs\")\n.asPrompt();\n\ndialog.addEventListener(\"validate\", (event) => {\n// Validate the form inputs in `dialog.content`.\n\nif (validationHasFailed) {\nevent.preventDefault();\n}\n});\n\ndialog.addEventListener(\"primary\", () => {\n// The dialog has been successfully validated\n// and was submitted by the user.\n// You can access form inputs through `dialog.content`.\n});\n
    "},{"location":"migration/wsc55/dialogs/#changes-to-the-template","title":"Changes to the Template","text":"

    Both the old and the new API support the use of existing elements to create dialogs. It is recommended to use <template> in this case which will never be rendered and has a well-defined role.

    <!-- Previous -->\n<div id=\"myDialog\" style=\"display: none\">\n  <!-- \u2026 -->\n</div>\n\n<!-- Use instead -->\n<template id=\"myDialog\">\n  <!-- \u2026 -->\n</template>\n

    Dialogs have historically been using the same HTML markup that regular pages do, including but not limited to the use of sections. For dialogs that use only a single container it is recommend to drop the section entirely.

    If your dialog contain multiple sections it is recommended to skip the title of the first section.

    "},{"location":"migration/wsc55/dialogs/#migration-by-example","title":"Migration by Example","text":"

    There is no universal pattern that fits every case, because dialogs vary greatly between each other and the required functionality causes the actual implementation to be different.

    As an example we have migrated the dialog to create a new box to use the new API. It uses a prompt dialog that automagically adds form controls and fires an event once the user submits the dialog. You can find the commit 3a9210f229f6a2cf5e800c2c4536c9774d02fc86 on GitHub.

    The changes can be summed up as follows:

    1. Use a <template> element for the dialog content.
    2. Remove the .formSubmit section from the HTML.
    3. Unwrap the contents by stripping the .section.
    4. Create and store the reference to the dialog in a property for later re-use.
    5. Interact with the dialog\u2019s .content property and make use of an event listener to handle the user interaction.

    WoltLab Suite 6.0 introduces Font Awesome 6.0 which is a major upgrade over the previously used Font Awesome 4.7 icon library. The new version features not only many hundreds of new icons but also focused a lot more on icon consistency, namely the proper alignment of icons within the grid.

    The previous implementation of Font Awesome 4 included shims for Font Awesome 3 that was used before, the most notable one being the .icon notation instead of .fa as seen in Font Awesome 4 and later. In addition, Font Awesome 5 introduced the concept of different font weights to separate icons which was further extended in Font Awesome 6.

    In WoltLab Suite 6.0 we have made the decision to make a clean cut and drop support for the Font Awesome 3 shim as well as a Font Awesome 4 shim in order to dramatically reduce the CSS size and to clean up the implementation. Brand icons had been moved to a separate font in Font Awesome 5, but since more and more fonts are being added we have stepped back from relying on that font. We have instead made the decision to embed brand icons using inline SVGs which are much more efficient when you only need a handful of brand icons instead of loading a 100kB+ font just for a few icons.

    "},{"location":"migration/wsc55/icons/#misuse-of-icons-as-buttons","title":"Misuse of Icons as Buttons","text":"

    One pattern that could be found every here and then was the use of icons as buttons. Using icons in buttons is fine, as long as there is a readable title and that they are properly marked as buttons.

    A common misuse looks like this:

    <span class=\"icon icon16 fa-times pointer jsMyDeleteButton\" data-some-object-id=\"123\"></span>\n

    This example has a few problems, for starters it is not marked as a button which would require both role=\"button\" and tabindex=\"0\" to be recognized as such. Additionally there is no title which leaves users clueless about what the option does, especially visually impaired users are possibly unable to identify the icon.

    WoltLab Suite 6.0 addresses this issue by removing all default styling from <button> elements, making them the ideal choice for button type elements.

    <button class=\"jsMyDeleteButton\" data-some-object-id=\"123\" title=\"descriptive title here\">{icon name='xmark'}</button>\n

    Historically the application boot in WCF\u2019s constructor performed processing based on fundamentally request-specific values, such as the accessed URL, the request body, or cookies. This is problematic, because this makes the boot dependent on the HTTP environment which may not be be available, e.g. when using the CLI interface for maintenance jobs. The latter needs to emulate certain aspects of the HTTP environment for the boot to succeed. Furthermore one of the goals of the introduction of PSR-7/PSR-15-based request processing that was started in WoltLab Suite 5.5 is the removal of implicit global state in favor of explicitly provided values by means of a ServerRequestInterface and thus to achieve a cleaner architecture.

    To achieve a clean separation this type of request-specific logic will incrementally be moved out of the application boot in WCF\u2019s constructor and into the request processing stack that is launched by RequestHandler, e.g. by running appropriate PSR-15 middleware.

    An example of this type of request-specific logic that was previously happening during application boot is the check that verifies whether a user is banned and denies access otherwise. This check is based on a request-specific value, namely the user\u2019s session which in turn is based on a provided (HTTP) cookie. It is now moved into the CheckUserBan middleware.

    This move implies that custom scripts that include WoltLab Suite Core\u2019s global.php, without also invoking RequestHandler will no longer be able to rely on this type of access control having happened and will need to implement it themselves, e.g. by manually running the appropriate middlewares.

    Notably the following checks have been moved into a middleware:

    The initialization of the session itself and dependent subsystems (e.g. the user object and thus the current language) is still running during application boot for now. However it is planned to also move the session initialization into the middleware in a future version and then providing access to the session by adding an attribute on the ServerRequestInterface, instead of querying the session via WCF::getSession(). As such you should begin to stop relying on the session and user outside of RequestHandler\u2019s middleware stack and should also avoid calling WCF::getUser() and WCF::getSession() outside of a controller, instead adding a User parameter to your methods to allow an appropriate user to be passed from the outside.

    An example of a method that implicitly relies on these global values is the VisitTracker's trackObjectVisit() method. It only takes the object type, object ID and timestamp as the parameter and will determine the userID by itself. The trackObjectVisitByUserIDs() method on the other hand does not rely on global values. Instead the relevant user IDs need to be passed explicitly from the controller as parameters, thus making the information the method works with explicit. This also makes the method reusable for use cases where an object should be marked as visited for a user other than the active user, without needing to temporarily switch the active user in the session.

    The same is true for \u201cpermission checking\u201d methods on DatabaseObjects. Instead of having a $myObject->canView() method that uses WCF::getSession() or WCF::getUser() internally, the user should explicitly be passed to the method as a parameter, allowing for permission checks to happen in a different context, for example send sending notification emails.

    Likewise event listeners should not access these request-specific values at all, because they are unable to know whether the event was fired based on these request-specific values or whether some programmatic action fired the event for another arbitrary user. Instead they must retrieve the appropriate information from the event data only.

    "},{"location":"migration/wsc55/php/#bootstrap-scripts","title":"Bootstrap Scripts","text":"

    WoltLab Suite 6.0 adds package-specific bootstrap scripts allowing a package to execute logic during the application boot to prepare the environment before the request is passed through the middleware pipeline into the controller in RequestHandler.

    Bootstrap scripts are stored in the lib/bootstrap/ directory of WoltLab Suite Core with the package identifier as the file name. They do not need to be registered explicitly, as one future goal of the bootstrap scripts is reducing the amount of system state that needs to be stored within the database. Instead WoltLab Suite Core will automatically create a bootstrap loader that includes all installed bootstrap scripts as part of the package installation and uninstallation process.

    Bootstrap scripts will be loaded and the bootstrap functions will executed based on a topological sorting of all installed packages. A package can rely on all bootstrap scripts of its dependencies being loaded before its own bootstrap script is loaded. It can also rely on all bootstrap functions of its dependencies having executed before its own bootstrap functions is executed. However it cannot rely on any specific loading and execution order of non-dependencies.

    As hinted at in the previous paragraph, executing the bootstrap scripts happens in two phases:

    1. All bootstrap scripts will be include()d in topological order. The script is expected to return a Closure that is executed in phase 2.
    2. Once all bootstrap scripts have been included, the returned Closures will be executed in the same order the bootstrap scripts were loaded.
    files/lib/bootstrap/com.example.foo.php
    <?php\n\n// Phase (1).\n\nreturn static function (): void {\n    // Phase (2).\n};\n

    For the vast majority of packages it is expected that the phase (1) bootstrapping is not used, except to return the Closure. Instead the logic should reside in the Closures body that is executed in phase (2).

    "},{"location":"migration/wsc55/php/#registering-ievent-listeners","title":"Registering IEvent listeners","text":"

    As previously mentioned in the Application Boot section, WoltLab Suite 6.0 improves support for PSR-7/PSR-15-based request processing that was initially announced with WoltLab Suite 5.5.

    WoltLab Suite 5.5 added support for returning a PSR-7 ResponseInterface from a controller and recommended to migrate existing controllers based on AbstractAction to make use of RedirectResponse and JsonResponse instead of using HeaderUtil::redirect() or manually emitting JSON with appropriate headers. Processing the request values still used PHP\u2019s superglobals (specifically $_GET and $_POST).

    WoltLab Suite 6.0 adds support for controllers based on PSR-15\u2019s RequestHandlerInterface, supporting request processing based on a provided PSR-7 ServerRequestInterface object.

    "},{"location":"migration/wsc55/php/#recommended-changes-for-woltlab-suite-60","title":"Recommended changes for WoltLab Suite 6.0","text":"

    It is recommended to use RequestHandlerInterface-based controllers whenever an AbstractAction would previously be used. Furthermore any AJAX-based logic that would previously rely on AJAXProxyAction combined with a method in an AbstractDatabaseObjectAction should also be implemented using a dedicated RequestHandlerInterface-based controller. Both AbstractAction and AJAXProxyAction-based AJAX requests should be considered soft-deprecated going forward.

    When creating a RequestHandlerInterface-based controller, care should be taken to ensure no mutable state is stored in object properties of the controller itself. The state of the controller object must be identical before, during and after a request was processed. Any required values must be passed explicitly by means of method parameters and return values. Likewise any functionality called by the controller\u2019s handle() method should not rely on implicit global values, such as WCF::getUser(), as was explained in the previous section about request-specific logic.

    The recommended pattern for a RequestHandlerInterface-based controller looks as follows:

    files/lib/action/MyFancyAction.class.php
    <?php\n\nnamespace wcf\\action;\n\nuse Laminas\\Diactoros\\Response;\nuse Psr\\Http\\Message\\ServerRequestInterface;\nuse Psr\\Http\\Message\\ResponseInterface;\nuse Psr\\Http\\Server\\RequestHandlerInterface;\n\nfinal class MyFancyAction implements RequestHandlerInterface\n{\n    public function __construct()\n    {\n        /* 0. Explicitly register services used by the controller, to\n         *    make dependencies explicit and to avoid accidentally using\n         *    global state outside of a controller.\n         */\n    }\n\n    public function handle(ServerRequestInterface $request): ResponseInterface\n    {\n        /* 1. Perform permission checks and input validation. */\n\n        /* 2. Perform the action. The action must not rely on global state,\n         *    but instead only on explicitly passed values. It should assume\n         *    that permissions have already been validated by the controller,\n         *    allowing it to be reusable programmatically.\n         */\n\n        /* 3. Perform post processing. */\n\n        /* 4. Prepare the response, e.g. by querying an updated object from\n         *    the database.\n         */\n\n        /* 5. Send the response. */\n        return new Response();\n    }\n}\n

    It is recommended to leverage Valinor for structural validation of input values if using the FormBuilder is not a good fit, specifically for any values that are provided implicitly and are expected to be correct. WoltLab Suite includes a middleware that will automatically convert unhandled MappingErrors into a response with status HTTP 400 Bad Request.

    XSRF validation will implicitly be performed for any request that uses a HTTP verb other than GET. Likewise any requests with a JSON body will automatically be decoded by a middleware and stored as the ServerRequestInterface\u2019s parsed body.

    The new WoltLabSuite/Core/Ajax/Backend module may be used to easily query a RequestHandlerInterface-based controller. The JavaScript code must not make any assumptions about the URI structure to reach the controller. Instead the endpoint must be generated using LinkHandler and explicitly provided, e.g. by storing it in a data-endpoint attribute:

    <button\n    class=\"button fancyButton\"\n    data-endpoint=\"{link controller='MyFancy'}{/link}\"\n>Click me!</button>\n
    const button = document.querySelector('.fancyButton');\nbutton.addEventListener('click', async (event) => {\nconst request = prepareRequest(button.dataset.endpoint)\n.get(); // or: .post(\u2026)\n\nconst response = await request.fetchAsResponse(); // or: .fetchAsJson()\n});\n

    The Psr15DialogForm class combined with the usingFormBuilder() method of dialogFactory() provides a \u201cbatteries-included\u201d solution to create a AJAX- and FormBuilder-based RequestHandlerInterface-based controller.

    Within the JavaScript code the endpoint is queried using:

    const { ok, result } = await dialogFactory()\n.usingFormBuilder()\n.fromEndpoint(url);\n

    The returned Promise will resolve when the dialog is closed, either by successfully submitting the form or by manually closing it and thus aborting the process. If the form was submitted successfully ok will be true and result will contain the controller\u2019s response. If the dialog was closed without successfully submitting the form, ok will be false and result will be set to undefined.

    Within the PHP code, the form may be created as usual, but use Psr15DialogForm as the form document. The controller must return $dialogForm->toJsonResponse() for GET requests and validate the ServerRequestInterface using $dialogForm->validateRequest($request) for POST requests. The latter will return a ResponseInterface to be returned if the validation fails, otherwise null is returned. If validation succeeded, the controller must perform the resulting action and return a JsonResponse with the result key:

    if ($request->getMethod() === 'GET') {\n    return $dialogForm->toResponse();\n} elseif ($request->getMethod() === 'POST') {\n    $response = $dialogForm->validateRequest($request);\n    if ($response !== null) {\n        return $response;\n    }\n\n    $data = $dialogForm->getData();\n\n    // Use $data.\n\n    return new JsonResponse([\n        'result' => [\n            'some' => 'value',\n        ],\n    ]);\n} else {\n    // The used method is validated by a middleware.

    WoltLab Suite 6.0 increases the System Requirements to require PHP\u2019s intl extension to be installed and enabled, allowing you to rely on the functionality provided by it to better match the rules and conventions of the different languages and regions of the world.

    One example would be the formatting of numbers. WoltLab Suite included a feature to group digits within large numbers since early versions using the StringUtil::addThousandsSeparator() method. While this method was able to account for some language-specific differences, e.g. by selecting an appropriate separator character based on a phrase, it failed to account for all the differences in number formatting across countries and cultures.

    As an example, English as written in the United States of America uses commas to create groups of three digits within large numbers: 123,456,789. English as written in India on the other hand also uses commas, but digits are not grouped into groups of three. Instead the right-most three digits form a group and then another comma is added every two digits: 12,34,56,789.

    Another example would be German as used within Germany and Switzerland. While both countries use groups of three, the separator character differs. Germany uses a dot (123.456.789), whereas Switzerland uses an apostrophe (123\u2019456\u2019789). The correct choice of separator could already be configured using the afore-mentioned phrase, but this is both inconvenient and fails to account for other differences between the two countries. It also made it hard to keep the behavior up to date when rules change.

    PHP\u2019s intl extension on the other hand builds on the official Unicode rules, by relying on the ICU library published by the Unicode consortium. As such it is aware of the rules of all relevant languages and regions of the world and it is already kept up to date by the operating system\u2019s package manager.

    For the four example regions (en_US, en_IN, de_DE, de_CH) intl\u2019s NumberFormatter class will format the number 123456789 as follows, correctly implementing the rules:

    php > var_dump((new NumberFormatter('en_US', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(11) \"123,456,789\"\nphp > var_dump((new NumberFormatter('en_IN', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(12) \"12,34,56,789\"\nphp > var_dump((new NumberFormatter('de_DE', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(11) \"123.456.789\"\nphp > var_dump((new NumberFormatter('de_CH', \\NumberFormatter::DEFAULT_STYLE))->format(123_456_789));\nstring(15) \"123\u2019456\u2019789\"\n

    WoltLab Suite\u2019s StringUtil::formatNumeric() method is updated to leverage the NumberFormatter internally. However your package might have special requirements regarding formatting, for example when formatting currencies where the position of the currency symbol differs across languages. In those cases your package should manually create an appropriately configured class from Intl\u2019s feature set. The correct locale can be queried by the new Language::getLocale() method.

    Another use case that showcases the Language::getLocale() method might be localizing a country name using locale_get_display_region():

    php > var_dump(\\wcf\\system\\WCF::getLanguage()->getLocale());\nstring(5) \"en_US\"\nphp > var_dump(locale_get_display_region('_DE', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(7) \"Germany\"\nphp > var_dump(locale_get_display_region('_US', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(13) \"United States\"\nphp > var_dump(locale_get_display_region('_IN', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(5) \"India\"\nphp > var_dump(locale_get_display_region('_BR', \\wcf\\system\\WCF::getLanguage()->getLocale()));\nstring(6) \"Brazil\"\n

    See WoltLab/WCF#4788 for details.

    "},{"location":"migration/wsc55/templates/#time-rendering","title":"Time Rendering","text":"

    The |time, |plainTime and |date modifiers have been deprecated and replaced by a unified {time} function.

    The main benefit is that it is no longer necessary to specify the @ symbol when rendering the interactive time element, making it easier to perform a security review of templates by searching for the @ symbol.

    See WoltLab/WCF#5459 for details.

    "},{"location":"migration/wsc55/templates/#comments","title":"Comments","text":"

    In WoltLab Suite 6.0 the comment system has been overhauled. In the process, the integration of comments via templates has been significantly simplified:

    {include file='comments' commentContainerID='someElementId' commentObjectID=$someObjectID}\n

    An example for the migration of existing template integrations can be found here.

    See WoltLab/WCF#5210 for more details.

    "},{"location":"package/database-php-api/","title":"Database PHP API","text":"

    While the sql package installation plugin supports adding and removing tables, columns, and indices, it is not able to handle cases where the added table, column, or index already exist. We have added a new PHP-based API to manipulate the database scheme which can be used in combination with the database package installation plugin that skips parts that already exist:

    return [\n    // list of `DatabaseTable` objects\n];\n

    All of the relevant components can be found in the wcf\\system\\database\\table namespace.

    "},{"location":"package/database-php-api/#database-tables","title":"Database Tables","text":"

    There are two classes representing database tables: DatabaseTable and PartialDatabaseTable. If a new table should be created, use DatabaseTable. In all other cases, PartialDatabaseTable should be used as it provides an additional save-guard against accidentally creating a new table by having a typo in the table name: If the tables does not already exist, a table represented by PartialDatabaseTable will cause an exception (while a DatabaseTable table will simply be created).

    To create a table, a DatabaseTable object with the table's name as to be created and table's columns, foreign keys and indices have to be specified:

    DatabaseTable::create('foo1_bar')\n    ->columns([\n        // columns\n    ])\n    ->foreignKeys([\n        // foreign keys\n    ])\n    ->indices([\n        // indices\n    ])\n

    To update a table, the same code as above can be used, except for PartialDatabaseTable being used instead of DatabaseTable.

    To drop a table, only the drop() method has to be called:

    PartialDatabaseTable::create('foo1_bar')\n    ->drop()\n
    "},{"location":"package/database-php-api/#columns","title":"Columns","text":"

    To represent a column of a database table, you have to create an instance of the relevant column class found in the wcf\\system\\database\\table\\column namespace. Such instances are created similarly to database table objects using the create() factory method and passing the column name as the parameter.

    Every column type supports the following methods:

    Depending on the specific column class implementing additional interfaces, the following methods are also available:

    Additionally, there are some additionally classes of commonly used columns with specific properties:

    Examples:

    DefaultFalseBooleanDatabaseTableColumn::create('isDisabled')\n\nNotNullInt10DatabaseTableColumn::create('fooTypeID')\n\nSmallintDatabaseTableColumn::create('bar')\n    ->length(5)\n    ->notNull()\n
    "},{"location":"package/database-php-api/#foreign-keys","title":"Foreign Keys","text":"

    Foreign keys are represented by DatabaseTableForeignKey objects: 

    DatabaseTableForeignKey::create()\n    ->columns(['fooID'])\n    ->referencedTable('wcf1_foo')\n    ->referencedColumns(['fooID'])\n    ->onDelete('CASCADE')\n

    The supported actions for onDelete() and onUpdate() are CASCADE, NO ACTION, and SET NULL. To drop a foreign key, all of the relevant data to create the foreign key has to be present and the drop() method has to be called.

    DatabaseTableForeignKey::create() also supports the foreign key name as a parameter. If it is not present, DatabaseTable::foreignKeys() will automatically set one based on the foreign key's data.

    "},{"location":"package/database-php-api/#indices","title":"Indices","text":"

    Indices are represented by DatabaseTableIndex objects: 

    DatabaseTableIndex::create('fooID')\n    ->type(DatabaseTableIndex::UNIQUE_TYPE)\n    ->columns(['fooID'])\n

    There are four different types: DatabaseTableIndex::DEFAULT_TYPE (default), DatabaseTableIndex::PRIMARY_TYPE, DatabaseTableIndex::UNIQUE_TYPE, and DatabaseTableIndex::FULLTEXT_TYPE. For primary keys, there is also the DatabaseTablePrimaryIndex class which automatically sets the type to DatabaseTableIndex::PRIMARY_TYPE. To drop a index, all of the relevant data to create the index has to be present and the drop() method has to be called.

    The index name is specified as the parameter to DatabaseTableIndex::create(). It is strongly recommended to specify an explicit name (WoltLab/WCF#4505). If no name is given, DatabaseTable::indices() will automatically set one based on the index data.

    <instructions type=\"update\" fromversion=\"1.0.0\">\n<!-- \u2026 -->\n</instructions>\n<instructions type=\"update\" fromversion=\"1.0.1\">\n<!-- \u2026 -->\n</instructions>\n

    In this example WoltLab Suite Core will pick the first update block since it allows an update from 1.0.0 -> 1.0.2. The other block is not considered, since the currently installed version is 1.0.0. After applying the update block (fromversion=\"1.0.0\"), the version now reads 1.0.2.

    "},{"location":"package/package-xml/#instruction","title":"<instruction>","text":"

    Example:

    <instruction type=\"objectTypeDefinition\">objectTypeDefinition.xml</instruction>\n

    The attribute type specifies the instruction type which is used to determine the package installation plugin (PIP) invoked to handle its value. The value must be a valid file relative to the location of package.xml. Many PIPs provide default file names which are used if no value is given:

    <instruction type=\"objectTypeDefinition\" />\n

    There is a list of all default PIPs available.

    Both the type-attribute and the element value are case-sensitive. Windows does not care if the file is called objecttypedefinition.xml but was referenced as objectTypeDefinition.xml, but both Linux and Mac systems will be unable to find the file.

    In addition to the type attribute, an optional run attribute (with standalone as the only valid value) is supported which forces the installation to execute this PIP in an isolated request, allowing a single, resource-heavy PIP to execute without encountering restrictions such as PHP\u2019s memory_limit or max_execution_time:

    <instruction type=\"file\" run=\"standalone\" />\n
    "},{"location":"package/package-xml/#void","title":"<void/>","text":"

    Sometimes a package update should only adjust the metadata of the package, for example, an optional package was added. However, WoltLab Suite Core requires that the list of <instructions> is non-empty. Instead of using a dummy <instruction> that idempotently updates some PIP, the <void/> tag can be used for this use-case.

    Using the <void/> tag is only valid for <instructions type=\"update\"> and must not be accompanied by other <instruction> tags.

    Example:

    <instructions type=\"update\" fromversion=\"1.0.0\">\n<void/>\n</instructions>\n

    Registers an object type definition. An object type definition is a blueprint for a certain behaviour that is particularized by objectTypes. As an example: Tags can be attached to different types of content (such as forum posts or gallery images). The bulk of the work is implemented in a generalized fashion, with all the tags stored in a single database table. Certain things, such as permission checking, need to be particularized for the specific type of content, though. Thus tags (or rather \u201ctaggable content\u201d) are registered as an object type definition. Posts are then registered as an object type, implementing the \u201ctaggable content\u201d behaviour.

    Other types of object type definitions include attachments, likes, polls, subscriptions, or even the category system.

    "},{"location":"php/apps/","title":"Apps for WoltLab Suite","text":""},{"location":"php/apps/#introduction","title":"Introduction","text":"

    Apps are among the most powerful components in WoltLab Suite. Unlike plugins that extend an existing functionality and pages, apps have their own frontend with a dedicated namespace, database table prefixes and template locations.

    However, apps are meant to be a logical (and to some extent physical) separation from other parts of the framework, including other installed apps. They offer an additional layer of isolation and enable you to re-use class and template names that are already in use by the Core itself.

    If you've come here, thinking about the question if your next package should be an app instead of a regular plugin, the result is almost always: No.

    "},{"location":"php/apps/#differences-to-plugins","title":"Differences to Plugins","text":"

    Apps do offer a couple of unique features that are not available to plugins and there are valid reasons to use one instead of a plugin, but they also increase both the code and system complexity. There is a performance penalty for each installed app, regardless if it is actively used in a request or not, simplying being there forces the Core to include it in many places, for example, class resolution or even simple tasks such as constructing a link.

    "},{"location":"php/apps/#unique-namespace","title":"Unique Namespace","text":"

    Each app has its own unique namespace that is entirely separated from the Core and any other installed apps. The namespace is derived from the last part of the package identifier, for example, com.example.foo will yield the namespace foo.

    The namespace is always relative to the installation directory of the app, it doesn't matter if the app is installed on example.com/foo/ or in example.com/bar/, the namespace will always resolve to the right directory.

    This app namespace is also used for ACP templates, frontend templates and files:

    <!-- somewhere in the package.xml -->\n<instructions type=\"file\" application=\"foo\" />\n
    "},{"location":"php/apps/#unique-database-table-prefix","title":"Unique Database Table Prefix","text":"

    All database tables make use of a generic prefix that is derived from one of the installed apps, including wcf which resolves to the Core itself. Following the aforementioned example, the new prefix fooN_ will be automatically registered and recognized in any generated statement.

    Any DatabaseObject that uses the app's namespace is automatically assumed to use the app's database prefix. For instance, foo\\data\\bar\\Bar is implicitly mapped to the database table fooN_bar.

    The app prefix is recognized in SQL-PIPs and statements that reference one of its database tables are automatically rewritten to use the Core's instance number.

    "},{"location":"php/apps/#separate-domain-and-path-configuration","title":"Separate Domain and Path Configuration","text":"

    Any controller that is provided by a plugin is served from the configured domain and path of the corresponding app, such as plugins for the Core are always served from the Core's directory. Apps are different and use their own domain and/or path to present their content, additionally, this allows the app to re-use a controller name that is already provided by the Core or any other app itself.

    "},{"location":"php/apps/#creating-an-app","title":"Creating an App","text":"

    This is a non-reversible operation! Once a package has been installed, its type cannot be changed without uninstalling and reinstalling the entire package, an app will always be an app and vice versa.

    As the database table columns are not explicit properties of the classes extending wcf\\data\\DatabaseObject but rather stored in DatabaseObject::$data and accessible via DatabaseObject::__get($name), the IDE we use, PhpStorm, is neither able to autocomplete such property access nor to interfere the type of the property.

    To solve this problem, @property-read tags must be added to the class documentation which registers the database table columns as public read-only properties:

     * @property-read   propertyType    $propertyName   property description\n

    The properties have to be in the same order as the order in the database table.

    The following table provides templates for common description texts so that similar database table columns have similar description texts.

    The only exception to this rule is if the class overwrites the create() method which itself has to be properly documentation then.

    The first and second line makes sure that when calling the create() or getDecoratedObject() method, the return value is correctly recognized and not just a general DatabaseObject instance. The third line tells the IDE (if @mixin is supported) that the database object editor decorates the database object and therefore offers autocompletion for properties and methods from the database object class itself.

    The ternary operator can be used for short conditioned assignments:

    <?php\n\n$name = isset($tagArgs['name']) ? $tagArgs['name'] : 'default';\n

    The condition and the values should be short so that the code does not result in a very long line which thus decreases the readability compared to an if-else statement.

    Parentheses may only be used around the condition and not around the whole statement:

    <?php\n\n// do not do it like this\n$name = (isset($tagArgs['name']) ? $tagArgs['name'] : 'default');\n

    Parentheses around the conditions may not be used to wrap simple function calls:

    <?php\n\n// do not do it like this\n$name = (isset($tagArgs['name'])) ? $tagArgs['name'] : 'default';\n

    but have to be used for comparisons or other binary operators:

    <?php\n\n$value = ($otherValue > $upperLimit) ? $additionalValue : $otherValue;\n

    If you need to use more than one binary operator, use an if-else statement.

    The same rules apply to assigning array values:

    Database Objects provide a convenient and object-oriented approach to work with the database, but there can be use-cases that require raw access including writing methods for model classes. This section assumes that you have either used prepared statements before or at least understand how it works.

    "},{"location":"php/database-access/#the-preparedstatement-object","title":"The PreparedStatement Object","text":"

    The database access is designed around PreparedStatement, built on top of PHP's PDOStatement so that you call all of PDOStatement's methods, and each query requires you to obtain a statement object.

    <?php\n$statement = \\wcf\\system\\WCF::getDB()->prepare(\"SELECT * FROM wcf1_example\");\n$statement->execute();\nwhile ($row = $statement->fetchArray()) {\n    // handle result\n}\n
    "},{"location":"php/database-access/#query-parameters","title":"Query Parameters","text":"

    The example below illustrates the usage of parameters where each value is replaced with the generic ?-placeholder. Values are provided by calling $statement->execute() with a continuous, one-dimensional array that exactly match the number of question marks.

    <?php\n$sql = \"SELECT  *\n        FROM    wcf1_example\n        WHERE   exampleID = ?\n                OR bar IN (?, ?, ?, ?, ?)\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute([\n    $exampleID,\n    $list, $of, $values, $for, $bar\n]);\nwhile ($row = $statement->fetchArray()) {\n    // handle result\n}\n
    "},{"location":"php/database-access/#fetching-a-single-result","title":"Fetching a Single Result","text":"

    Do not attempt to use fetchSingleRow() or fetchSingleColumn() if the result contains more than one row.

    You can opt-in to retrieve only a single row from database and make use of shortcut methods to reduce the code that you have to write.

    <?php\n$sql = \"SELECT  *\n        FROM    wcf1_example\n        WHERE   exampleID = ?\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql, 1);\n$statement->execute([$exampleID]);\n$row = $statement->fetchSingleRow();\n

    There are two distinct differences when comparing with the example on query parameters above:

    1. The method prepare() receives a secondary parameter that will be appended to the query as LIMIT 1.
    2. Data is read using fetchSingleRow() instead of fetchArray() or similar methods, that will read one result and close the cursor.
    "},{"location":"php/database-access/#fetch-by-column","title":"Fetch by Column","text":"

    There is no way to return another column from the same row if you use fetchColumn() to retrieve data.

    Fetching an array is only useful if there is going to be more than one column per result row, otherwise accessing the column directly is much more convenient and increases the code readability.

    <?php\n$sql = \"SELECT  bar\n        FROM    wcf1_example\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\nwhile ($bar = $statement->fetchColumn()) {\n    // handle result\n}\n$bar = $statement->fetchSingleColumn();\n

    Similar to fetching a single row, you can also issue a query that will select a single row, but reads only one column from the result row.

    <?php\n$sql = \"SELECT  bar\n        FROM    wcf1_example\n        WHERE   exampleID = ?\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql, 1);\n$statement->execute([$exampleID]);\n$bar = $statement->fetchSingleColumn();\n
    "},{"location":"php/database-access/#fetching-all-results","title":"Fetching All Results","text":"

    If you want to fetch all results of a query but only store them in an array without directly processing them, in most cases, you can rely on built-in methods.

    To fetch all rows of query, you can use PDOStatement::fetchAll() with \\PDO::FETCH_ASSOC as the first parameter:

    <?php\n$sql = \"SELECT  *\n        FROM    wcf1_example\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$rows = $statement->fetchAll(\\PDO::FETCH_ASSOC);\n

    As a result, you get an array containing associative arrays with the rows of the wcf{WCF_N}_example database table as content.

    If you only want to fetch a list of the values of a certain column, you can use \\PDO::FETCH_COLUMN as the first parameter:

    <?php\n$sql = \"SELECT  exampleID\n        FROM    wcf1_example\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$exampleIDs = $statement->fetchAll(\\PDO::FETCH_COLUMN);\n

    As a result, you get an array with all exampleID values.

    The PreparedStatement class adds an additional methods that covers another common use case in our code: Fetching two columns and using the first column's value as the array key and the second column's value as the array value. This case is covered by PreparedStatement::fetchMap():

    <?php\n$sql = \"SELECT  exampleID, userID\n        FROM    wcf1_example_mapping\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$map = $statement->fetchMap('exampleID', 'userID');\n

    $map is a one-dimensional array where each exampleID value maps to the corresponding userID value.

    If there are multiple entries for a certain exampleID value with different userID values, the existing entry in the array will be overwritten and contain the last read value from the database table. Therefore, this method should generally only be used for unique combinations.

    If you do not have a combination of columns with unique pairs of values, but you want to get a list of userID values with the same exampleID, you can set the third parameter of fetchMap() to false and get a list:

    <?php\n$sql = \"SELECT  exampleID, userID\n        FROM    wcf1_example_mapping\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n$statement->execute();\n$map = $statement->fetchMap('exampleID', 'userID', false);\n

    Now, as a result, you get a two-dimensional array with the array keys being the exampleID values and the array values being arrays with all userID values from rows with the respective exampleID value.

    "},{"location":"php/database-access/#building-complex-conditions","title":"Building Complex Conditions","text":"

    Building conditional conditions can turn out to be a real mess and it gets even worse with SQL's IN (\u2026) which requires as many placeholders as there will be values. The solutions is PreparedStatementConditionBuilder, a simple but useful helper class with a bulky name, it is also the class used when accessing DatabaseObjecList::getConditionBuilder().

    <?php\n$conditions = new \\wcf\\system\\database\\util\\PreparedStatementConditionBuilder();\n$conditions->add(\"exampleID = ?\", [$exampleID]);\nif (!empty($valuesForBar)) {\n    $conditions->add(\"(bar IN (?) OR baz = ?)\", [$valuesForBar, $baz]);\n}\n

    The IN (?) in the example above is automatically expanded to match the number of items contained in $valuesForBar. Be aware that the method will generate an invalid query if $valuesForBar is empty!

    "},{"location":"php/database-access/#insert-or-update-in-bulk","title":"INSERT or UPDATE in Bulk","text":"

    Prepared statements not only protect against SQL injection by separating the logical query and the actual data, but also provides the ability to reuse the same query with different values. This leads to a performance improvement as the code does not have to transmit the query with for every data set and only has to parse and analyze the query once.

    <?php\n$data = ['abc', 'def', 'ghi'];\n\n$sql = \"INSERT INTO  wcf1_example\n                     (bar)\n        VALUES       (?)\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n\n\\wcf\\system\\WCF::getDB()->beginTransaction();\nforeach ($data as $bar) {\n    $statement->execute([$bar]);\n}\n\\wcf\\system\\WCF::getDB()->commitTransaction();\n

    It is generally advised to wrap bulk operations in a transaction as it allows the database to optimize the process, including fewer I/O operations.

    <?php\n$data = [\n    1 => 'abc',\n    3 => 'def',\n    4 => 'ghi'\n];\n\n$sql = \"UPDATE  wcf1_example\n        SET     bar = ?\n        WHERE   exampleID = ?\";\n$statement = \\wcf\\system\\WCF::getDB()->prepare($sql);\n\n\\wcf\\system\\WCF::getDB()->beginTransaction();\nforeach ($data as $exampleID => $bar) {\n    $statement->execute([\n        $bar,\n        $exampleID\n    ]);\n}\n\\wcf\\system\\WCF::getDB()->commitTransaction();\n
    "},{"location":"php/database-objects/","title":"Database Objects","text":"

    WoltLab Suite uses a unified interface to work with database rows using an object based approach instead of using native arrays holding arbitrary data. Each database table is mapped to a model class that is designed to hold a single record from that table and expose methods to work with the stored data, for example providing assistance when working with normalized datasets.

    Developers are required to provide the proper DatabaseObject implementations themselves, they're not automatically generated, all though the actual code that needs to be written is rather small. The following examples assume the fictional database table wcf1_example, exampleID as the auto-incrementing primary key and the column bar to store some text.

    "},{"location":"php/database-objects/#databaseobject","title":"DatabaseObject","text":"

    The basic model derives from wcf\\data\\DatabaseObject and provides a convenient constructor to fetch a single row or construct an instance using pre-loaded rows.

    files/lib/data/example/Example.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObject;\n\nclass Example extends DatabaseObject {}\n

    The class is intended to be empty by default and there only needs to be code if you want to add additional logic to your model. Both the class name and primary key are determined by DatabaseObject using the namespace and class name of the derived class. The example above uses the namespace wcf\\\u2026 which is used as table prefix and the class name Example is converted into exampleID, resulting in the database table name wcfN_example with the primary key exampleID.

    You can prevent this automatic guessing by setting the class properties $databaseTableName and $databaseTableIndexName manually.

    "},{"location":"php/database-objects/#databaseobjectdecorator","title":"DatabaseObjectDecorator","text":"

    If you already have a DatabaseObject class and would like to extend it with additional data or methods, for example by providing a class ViewableExample which features view-related changes without polluting the original object, you can use DatabaseObjectDecorator which a default implementation of a decorator for database objects.

    files/lib/data/example/ViewableExample.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObjectDecorator;\n\nclass ViewableExample extends DatabaseObjectDecorator {\n    protected static $baseClass = Example::class;\n\n    public function getOutput() {\n        $output = '';\n\n        // [determine output]\n\n        return $output;\n    }\n}\n

    It is mandatory to set the static $baseClass property to the name of the decorated class.

    Like for any decorator, you can directly access the decorated object's properties and methods for a decorated object by accessing the property or calling the method on the decorated object. You can access the decorated objects directly via DatabaseObjectDecorator::getDecoratedObject().

    "},{"location":"php/database-objects/#databaseobjecteditor","title":"DatabaseObjectEditor","text":"

    This is the low-level interface to manipulate data rows, it is recommended to use AbstractDatabaseObjectAction.

    Adding, editing and deleting models is done using the DatabaseObjectEditor class that decorates a DatabaseObject and uses its data to perform the actions.

    files/lib/data/example/ExampleEditor.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObjectEditor;\n\nclass ExampleEditor extends DatabaseObjectEditor {\n    protected static $baseClass = Example::class;\n}\n

    The editor class requires you to provide the fully qualified name of the model, that is the class name including the complete namespace. Database table name and index key will be pulled directly from the model.

    "},{"location":"php/database-objects/#create-a-new-row","title":"Create a new row","text":"

    Inserting a new row into the database table is provided through DatabaseObjectEditor::create() which yields a DatabaseObject instance after creation.

    <?php\n$example = \\wcf\\data\\example\\ExampleEditor::create([\n    'bar' => 'Hello World!'\n]);\n\n// output: Hello World!\necho $example->bar;\n
    "},{"location":"php/database-objects/#updating-an-existing-row","title":"Updating an existing row","text":"

    The internal state of the decorated DatabaseObject is not altered at any point, the values will still be the same after editing or deleting the represented row. If you need an object with the latest data, you'll have to discard the current object and refetch the data from database.

    <?php\n$example = new \\wcf\\data\\example\\Example($id);\n$exampleEditor = new \\wcf\\data\\example\\ExampleEditor($example);\n$exampleEditor->update([\n    'bar' => 'baz'\n]);\n\n// output: Hello World!\necho $example->bar;\n\n// re-creating the object will query the database again and retrieve the updated value\n$example = new \\wcf\\data\\example\\Example($example->id);\n\n// output: baz\necho $example->bar;\n
    "},{"location":"php/database-objects/#deleting-a-row","title":"Deleting a row","text":"

    Similar to the update process, the decorated DatabaseObject is not altered and will then point to an inexistent row.

    "},{"location":"php/database-objects/#databaseobjectlist","title":"DatabaseObjectList","text":"

    Every row is represented as a single instance of the model, but the instance creation deals with single rows only. Retrieving larger sets of rows would be quite inefficient due to the large amount of queries that will be dispatched. This is solved with the DatabaseObjectList object that exposes an interface to query the database table using arbitrary conditions for data selection. All rows will be fetched using a single query and the resulting rows are automatically loaded into separate models.

    files/lib/data/example/ExampleList.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\DatabaseObjectList;\n\nclass ExampleList extends DatabaseObjectList {\n    public $className = Example::class;\n}\n

    The following code listing illustrates loading a large set of examples and iterating over the list to retrieve the objects.

    <?php\n$exampleList = new \\wcf\\data\\example\\ExampleList();\n// add constraints using the condition builder\n$exampleList->getConditionBuilder()->add('bar IN (?)', [['Hello World!', 'bar', 'baz']]);\n// actually read the rows\n$exampleList->readObjects();\nforeach ($exampleList as $example) {\n    echo $example->bar;\n}\n\n// retrieve the models directly instead of iterating over them\n$examples = $exampleList->getObjects();\n\n// just retrieve the number of rows\n$exampleCount = $exampleList->countObjects();\n

    DatabaseObjectList implements both SeekableIterator and Countable.

    Additionally, DatabaseObjectList objects has the following three public properties that are useful when fetching data with lists:

    For more advanced usage, there two additional fields that deal with the type of objects returned. First, let's go into a bit more detail what setting the $className property actually does:

    1. It is the type of database object in which the rows are wrapped.
    2. It determines which database table is actually queried and which index is used (see the $databaseTableName and $databaseTableIndexName properties of DatabaseObject).

    Sometimes you might use the database table of some database object but wrap the rows in another database object. This can be achieved by setting the $objectClassName property to the desired class name.

    In other cases, you might want to wrap the created objects in a database object decorator which can be done by setting the $decoratorClassName property to the desired class name:

    <?php\n$exampleList = new \\wcf\\data\\example\\ExampleList();\n$exampleList->decoratorClassName = \\wcf\\data\\example\\ViewableExample::class;\n

    Of course, you do not have to set the property after creating the list object, you can also set it by creating a dedicated class:

    files/lib/data/example/ViewableExampleList.class.php 
    <?php\nnamespace wcf\\data\\example;\n\nclass ViewableExampleList extends ExampleList {\n    public $decoratorClassName = ViewableExample::class;\n}\n
    "},{"location":"php/database-objects/#abstractdatabaseobjectaction","title":"AbstractDatabaseObjectAction","text":"

    Row creation and manipulation can be performed using the aforementioned DatabaseObjectEditor class, but this approach has two major issues:

    1. Row creation, update and deletion takes place silently without notifying any other components.
    2. Data is passed to the database adapter without any further processing.

    The AbstractDatabaseObjectAction solves both problems by wrapping around the editor class and thus provide an additional layer between the action that should be taken and the actual process. The first problem is solved by a fixed set of events being fired, the second issue is addressed by having a single entry point for all data editing.

    files/lib/data/example/ExampleAction.class.php 
    <?php\nnamespace wcf\\data\\example;\nuse wcf\\data\\AbstractDatabaseObjectAction;\n\nclass ExampleAction extends AbstractDatabaseObjectAction {\n    public $className = ExampleEditor::class;\n}\n
    "},{"location":"php/database-objects/#executing-an-action","title":"Executing an Action","text":"

    The method AbstractDatabaseObjectAction::validateAction() is internally used for AJAX method invocation and must not be called programmatically.

    The next example represents the same functionality as seen for DatabaseObjectEditor:

    <?php\nuse wcf\\data\\example\\ExampleAction;\n\n// create a row\n$exampleAction = new ExampleAction([], 'create', [\n    'data' => ['bar' => 'Hello World']\n]);\n$example = $exampleAction->executeAction()['returnValues'];\n\n// update a row using the id\n$exampleAction = new ExampleAction([1], 'update', [\n    'data' => ['bar' => 'baz']\n]);\n$exampleAction->executeAction();\n\n// delete a row using a model\n$exampleAction = new ExampleAction([$example], 'delete');\n$exampleAction->executeAction();\n

    You can access the return values both by storing the return value of executeAction() or by retrieving it via getReturnValues().

    "},{"location":"php/database-objects/#ajax-validation","title":"AJAX Validation","text":"

This means that ExampleAction must define both a public function baz() and public function validateBaz(), the name for the validation method is constructed by upper-casing the first character of the method name and prepending validate.

    The methods create, update and delete are available for all classes deriving from AbstractDatabaseObjectAction and directly pass the input data to the DatabaseObjectEditor.

    WoltLab Suite offers two distinct types of caches:

    1. Persistent caches created by cache builders whose data can be stored using different cache sources.
    2. Runtime caches store objects for the duration of a single request.
    "},{"location":"php/api/caches/#understanding-caching","title":"Understanding Caching","text":"

    Every so often, plugins make use of cache builders or runtime caches to store their data, even if there is absolutely no need for them to do so. Usually, this involves a strong opinion about the total number of SQL queries on a page, including but not limited to some magic treshold numbers, which should not be exceeded for \"performance reasons\".

    This misconception can easily lead into thinking that SQL queries should be avoided or at least written to a cache, so that it doesn't need to be executed so often. Unfortunately, this completely ignores the fact that both a single query can take down your app (e. g. full table scan on millions of rows), but 10 queries using a primary key on a table with a few hundred rows will not slow down your page.

    There are some queries that should go into caches by design, but most of the cache builders weren't initially there, but instead have been added because they were required to reduce the load significantly. You need to understand that caches always come at a cost, even a runtime cache does! In particular, they will always consume memory that is not released over the duration of the request lifecycle and potentially even leak memory by holding references to objects and data structures that are no longer required.

    Caching should always be a solution for a problem.

    "},{"location":"php/api/caches/#when-to-use-a-cache","title":"When to Use a Cache","text":"

    It's difficult to provide a definite answer or checklist when to use a cache and why it is required at this point, because the answer is: It depends. The permission cache for user groups is a good example for a valid cache, where we can achieve significant performance improvement compared to processing this data on every request.

    Its caches are build for each permutation of user group memberships that are encountered for a page request. Building this data is an expensive process that involves both inheritance and specific rules in regards to when a value for a permission overrules another value. The added benefit of this cache is that one cache usually serves a large number of users with the same group memberships and by computing these permissions once, we can serve many different requests. Also, the permissions are rather static values that change very rarely and thus we can expect a very high cache lifetime before it gets rebuild.

    "},{"location":"php/api/caches/#when-not-to-use-a-cache","title":"When not to Use a Cache","text":"

    I remember, a few years ago, there was a plugin that displayed a user's character from an online video game. The character sheet not only included a list of basic statistics, but also displayed the items that this character was wearing and or holding at the time.

    The data for these items were downloaded in bulk from the game's vendor servers and stored in a persistent cache file that periodically gets renewed. There is nothing wrong with the idea of caching the data on your own server rather than requesting them everytime from the vendor's servers - not only because they imposed a limit on the number of requests per hour.

    Unfortunately, the character sheet had a sub-par performance and the users were upset by the significant loading times compared to literally every other page on the same server. The author of the plugin was working hard to resolve this issue and was evaluating all kind of methods to improve the page performance, including deep-diving into the realm of micro-optimizations to squeeze out every last bit of performance that is possible.

    The real problem was the cache file itself, it turns out that it was holding the data for several thousand items with a total file size of about 13 megabytes. It doesn't look that much at first glance, after all this isn't the '90s anymore, but unserializing a 13 megabyte array is really slow and looking up items in such a large array isn't exactly fast either.

    The solution was rather simple, the data that was fetched from the vendor's API was instead written into a separate database table. Next, the persistent cache was removed and the character sheet would now request the item data for that specific character straight from the database. Previously, the character sheet took several seconds to load and after the change it was done in a fraction of a second. Although quite extreme, this illustrates a situation where the cache file was introduced in the design process, without evaluating if the cache - at least how it was implemented - was really necessary.

    Caching should always be a solution for a problem. Not the other way around.

    "},{"location":"php/api/caches_persistent-caches/","title":"Persistent Caches","text":"

    Relational databases are designed around the principle of normalized data that is organized across clearly separated tables with defined releations between data rows. While this enables you to quickly access and modify individual rows and columns, it can create the problem that re-assembling this data into a more complex structure can be quite expensive.

    For example, the user group permissions are stored for each user group and each permissions separately, but in order to be applied, they need to be fetched and the cumulative values across all user groups of an user have to be calculated. These repetitive tasks on barely ever changing data make them an excellent target for caching, where all sub-sequent requests are accelerated because they no longer have to perform the same expensive calculations every time.

    It is easy to get lost in the realm of caching, especially when it comes to the decision if you should use a cache or not. When in doubt, you should opt to not use them, because they also come at a hidden cost that cannot be expressed through simple SQL query counts. If you haven't already, it is recommended that you read the introduction article on caching first, it provides a bit of background on caches and examples that should help you in your decision.

    "},{"location":"php/api/caches_persistent-caches/#abstractcachebuilder","title":"AbstractCacheBuilder","text":"

    Every cache builder should derive from the base class AbstractCacheBuilder that already implements the mandatory interface ICacheBuilder.

    Reading data from your cache builder is quite simple and follows a consistent pattern. The callee only needs to know the name of the cache builder, which parameters it requires and how the returned data looks like. It does not need to know how the data is retrieve, where it was stored, nor if it had to be rebuild due to the maximum lifetime.

    Runtime caches store objects created during the runtime of the script and are automatically discarded after the script terminates. Runtime caches are especially useful when objects are fetched by different APIs, each requiring separate requests. By using a runtime cache, you have two advantages:

    1. If the API allows it, you can delay fetching the actual objects and initially only tell the runtime cache that at some point in the future of the current request, you need the objects with the given ids. If multiple APIs do this one after another, all objects can be fetched using only one query instead of each API querying the database on its own.
    2. If an object with the same ID has already been fetched from database, this object is simply returned and can be reused instead of being fetched from database again.

    WoltLab Suite's event system allows manipulation of program flows and data without having to change any of the original source code. At many locations throughout the PHP code of WoltLab Suite Core and mainly through inheritance also in the applications and plugins, so called events are fired which trigger registered event listeners that get access to the object firing the event (or at least the class name if the event has been fired in a static method).

    This page focuses on the technical aspects of events and event listeners, the eventListener package installation plugin page covers how you can actually register an event listener. A comprehensive list of all available events is provided here.

    "},{"location":"php/api/events/#introductory-example","title":"Introductory Example","text":"

    Let's start with a simple example to illustrate how the event system works. Consider this pre-existing class:

    files/lib/system/example/ExampleComponent.class.php 
    <?php\nnamespace wcf\\system\\example;\nuse wcf\\system\\event\\EventHandler;\n\nclass ExampleComponent {\n    public $var = 1;\n\n    public function getVar() {\n        EventHandler::getInstance()->fireAction($this, 'getVar');\n\n        return $this->var;\n    }\n}\n

    where an event with event name getVar is fired in the getVar() method.

    If you create an object of this class and call the getVar() method, the return value will be 1, of course:

    <?php\n\n$example = new wcf\\system\\example\\ExampleComponent();\nif ($example->getVar() == 1) {\n    echo \"var is 1!\";\n}\nelse if ($example->getVar() == 2) {\n    echo \"var is 2!\";\n}\nelse {\n    echo \"No, var is neither 1 nor 2.\";\n}\n\n// output: var is 1!\n

    Now, consider that we have registered the following event listener to this event:

    files/lib/system/event/listener/ExampleEventListener.class.php 
    <?php\nnamespace wcf\\system\\event\\listener;\n\nclass ExampleEventListener implements IParameterizedEventListener {\n    public function execute($eventObj, $className, $eventName, array &$parameters) {\n        $eventObj->var = 2;\n    }\n}\n

    Whenever the event in the getVar() method is called, this method (of the same event listener object) is called. In this case, the value of the method's first parameter is the ExampleComponent object passed as the first argument of the EventHandler::fireAction() call in ExampleComponent::getVar(). As ExampleComponent::$var is a public property, the event listener code can change it and set it to 2.

    If you now execute the example code from above again, the output will change from var is 1! to var is 2! because prior to returning the value, the event listener code changes the value from 1 to 2.

    This introductory example illustrates how event listeners can change data in a non-intrusive way. Program flow can be changed, for example, by throwing a wcf\\system\\exception\\PermissionDeniedException if some additional constraint to access a page is not fulfilled.

    "},{"location":"php/api/events/#listening-to-events","title":"Listening to Events","text":"

    In order to listen to events, you need to register the event listener and the event listener itself needs to implement the interface wcf\\system\\event\\listener\\IParameterizedEventListener which only contains the execute method (see example above).

    The first parameter $eventObj of the method contains the passed object where the event is fired or the name of the class in which the event is fired if it is fired from a static method. The second parameter $className always contains the name of the class where the event has been fired. The third parameter $eventName provides the name of the event within a class to uniquely identify the exact location in the class where the event has been fired. The last parameter $parameters is a reference to the array which contains additional data passed by the method firing the event. If no additional data is passed, $parameters is empty.

    "},{"location":"php/api/events/#firing-events","title":"Firing Events","text":"

    If you write code and want plugins to have access at certain points, you can fire an event on your own. The only thing to do is to call the wcf\\system\\event\\EventHandler::fireAction($eventObj, $eventName, array &$parameters = []) method and pass the following parameters:

    1. $eventObj should be $this if you fire from an object context, otherwise pass the class name static::class.
    2. $eventName identifies the event within the class and generally has the same name as the method. In cases, were you might fire more than one event in a method, for example before and after a certain piece of code, you can use the prefixes before* and after* in your event names.
    3. $parameters is an optional array which allows you to pass additional data to the event listeners without having to make this data accessible via a property explicitly only created for this purpose. This additional data can either be just additional information for the event listeners about the context of the method call or allow the event listener to manipulate local data if the code, where the event has been fired, uses the passed data afterwards.
    "},{"location":"php/api/events/#example-using-parameters-argument","title":"Example: Using $parameters argument","text":"

    Consider the following method which gets some text that the methods parses.

    files/lib/system/example/ExampleParser.class.php 
    <?php\nnamespace wcf\\system\\example;\nuse wcf\\system\\event\\EventHandler;\n\nclass ExampleParser {\n    public function parse($text) {\n        // [some parsing done by default]\n\n        $parameters = ['text' => $text];\n        EventHandler::getInstance()->fireAction($this, 'parse', $parameters);\n\n        return $parameters['text'];\n    }\n}\n

    After the default parsing by the method itself, the author wants to enable plugins to do additional parsing and thus fires an event and passes the parsed text as an additional parameter. Then, a plugin can deliver the following event listener

    files/lib/system/event/listener/ExampleParserEventListener.class.php 
    <?php\nnamespace wcf\\system\\event\\listener;\n\nclass ExampleParserEventListener implements IParameterizedEventListener {\n    public function execute($eventObj, $className, $eventName, array &$parameters) {\n        $text = $parameters['text'];\n\n        // [some additional parsing which changes $text]\n\n        $parameters['text'] = $text;\n    }\n}\n

    which can access the text via $parameters['text'].

    This example can also be perfectly used to illustrate how to name multiple events in the same method. Let's assume that the author wants to enable plugins to change the text before and after the method does its own parsing and thus fires two events:

    files/lib/system/example/ExampleParser.class.php 
    <?php\nnamespace wcf\\system\\example;\nuse wcf\\system\\event\\EventHandler;\n\nclass ExampleParser {\n    public function parse($text) {\n        $parameters = ['text' => $text];\n        EventHandler::getInstance()->fireAction($this, 'beforeParsing', $parameters);\n        $text = $parameters['text'];\n\n        // [some parsing done by default]\n\n        $parameters = ['text' => $text];\n        EventHandler::getInstance()->fireAction($this, 'afterParsing', $parameters);\n\n        return $parameters['text'];\n    }\n}\n
    "},{"location":"php/api/events/#advanced-example-additional-form-field","title":"Advanced Example: Additional Form Field","text":"

    One common reason to use event listeners is to add an additional field to a pre-existing form (in combination with template listeners, which we will not cover here). We will assume that users are able to do both, create and edit the objects via this form. The points in the program flow of AbstractForm that are relevant here are:

    All of these cases can be covered the by following code in which we assume that wcf\\form\\ExampleAddForm is the form to create example objects and that wcf\\form\\ExampleEditForm extends wcf\\form\\ExampleAddForm and is used for editing existing example objects.

    files/lib/system/event/listener/ExampleAddFormListener.class.php 
    <?php\nnamespace wcf\\system\\event\\listener;\nuse wcf\\form\\ExampleAddForm;\nuse wcf\\form\\ExampleEditForm;\nuse wcf\\system\\exception\\UserInputException;\nuse wcf\\system\\WCF;\n\nclass ExampleAddFormListener implements IParameterizedEventListener {\n    protected $var = 0;\n\n    public function execute($eventObj, $className, $eventName, array &$parameters) {\n        $this->$eventName($eventObj);\n    }\n\n    protected function assignVariables() {\n        WCF::getTPL()->assign('var', $this->var);\n    }\n\n    protected function readData(ExampleEditForm $eventObj) {\n        if (empty($_POST)) {\n            $this->var = $eventObj->example->var;\n        }\n    }\n\n    protected function readFormParameters() {\n        if (isset($_POST['var'])) $this->var = intval($_POST['var']);\n    }\n\n    protected function save(ExampleAddForm $eventObj) {\n        $eventObj->additionalFields = array_merge($eventObj->additionalFields, ['var' => $this->var]);\n    }\n\n    protected function saved() {\n        $this->var = 0;\n    }\n\n    protected function validate() {\n        if ($this->var < 0) {\n            throw new UserInputException('var', 'isNegative');\n        }\n    }\n}\n

    The execute method in this example just delegates the call to a method with the same name as the event so that this class mimics the structure of a form class itself. The form object is passed to the methods but is only given in the method signatures as a parameter here whenever the form object is actually used. Furthermore, the type-hinting of the parameter illustrates in which contexts the method is actually called which will become clear in the following discussion of the individual methods:

    Lastly, the following XML file has to be used to register the event listeners (you can find more information about how to register event listeners on the eventListener package installation plugin page):

    eventListener.xml

    WoltLab Suite is capable of automatically creating a sitemap. This sitemap contains all static pages registered via the page package installation plugin and which may be indexed by search engines (checking the allowSpidersToIndex parameter and page permissions) and do not expect an object ID. Other pages have to be added to the sitemap as a separate object.

    The only prerequisite for sitemap objects is that the objects are instances of wcf\\data\\DatabaseObject and that there is a wcf\\data\\DatabaseObjectList implementation.

    First, we implement the PHP class, which provides us all database objects and optionally checks the permissions for a single object. The class must implement the interface wcf\\system\\sitemap\\object\\ISitemapObjectObjectType. However, in order to have some methods already implemented and ensure backwards compatibility, you should use the abstract class wcf\\system\\sitemap\\object\\AbstractSitemapObjectObjectType. The abstract class takes care of generating the DatabaseObjectList class name and list directly and implements optional methods with the default values. The only method that you have to implement yourself is the getObjectClass() method which returns the fully qualified name of the DatabaseObject class. The DatabaseObject class must implement the interface wcf\\data\\ILinkableObject.

    Other optional methods are:

    As an example, the implementation for users looks like this:

    files/lib/system/sitemap/object/UserSitemapObject.class.php 
    <?php\nnamespace wcf\\system\\sitemap\\object;\nuse wcf\\data\\user\\User;\nuse wcf\\data\\DatabaseObject;\nuse wcf\\system\\WCF;\n\n/**\n * User sitemap implementation.\n *\n * @author  Joshua Ruesweg\n * @copyright   2001-2017 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\Sitemap\\Object\n * @since   3.1\n */\nclass UserSitemapObject extends AbstractSitemapObjectObjectType {\n    /**\n     * @inheritDoc\n     */\n    public function getObjectClass() {\n        return User::class;\n    }\n\n    /**\n     * @inheritDoc\n     */\n    public function getLastModifiedColumn() {\n        return 'lastActivityTime';\n    }\n\n    /**\n     * @inheritDoc\n     */\n    public function canView(DatabaseObject $object) {\n        return WCF::getSession()->getPermission('user.profile.canViewUserProfile');\n    }\n}\n

    Next, the sitemap object must be registered as an object type:

    <type>\n<name>com.example.plugin.sitemap.object.user</name>\n<definitionname>com.woltlab.wcf.sitemap.object</definitionname>\n<classname>wcf\\system\\sitemap\\object\\UserSitemapObject</classname>\n<priority>0.5</priority>\n<changeFreq>monthly</changeFreq>\n<rebuildTime>259200</rebuildTime>\n</type>\n

    In addition to the fully qualified class name, the object type definition com.woltlab.wcf.sitemap.object and the object type name, the parameters priority, changeFreq and rebuildTime must also be specified. priority (https://www.sitemaps.org/protocol.html#prioritydef) and changeFreq (https://www.sitemaps.org/protocol.html#changefreqdef) are specifications in the sitemaps protocol and can be changed by the user in the ACP. The priority should be 0.5 by default, unless there is an important reason to change it. The parameter rebuildTime specifies the number of seconds after which the sitemap should be regenerated.

    Finally, you have to create the language variable for the sitemap object. The language variable follows the pattern wcf.acp.sitemap.objectType.{objectTypeName} and is in the category wcf.acp.sitemap.

    "},{"location":"php/api/user_activity_points/","title":"User Activity Points","text":"

    Users get activity points whenever they create content to award them for their contribution. Activity points are used to determine the rank of a user and can also be used for user conditions, for example for automatic user group assignments.

    To integrate activity points into your package, you have to register an object type for the defintion com.woltlab.wcf.user.activityPointEvent and specify a default number of points:

    <type>\n<name>com.example.foo.activityPointEvent.bar</name>\n<definitionname>com.woltlab.wcf.user.activityPointEvent</definitionname>\n<points>10</points>\n</type>\n

    The number of points awarded for this type of activity point event can be changed by the administrator in the admin control panel. For this form and the user activity point list shown in the frontend, you have to provide the language item

    wcf.user.activityPoint.objectType.com.example.foo.activityPointEvent.bar\n

    that contains the name of the content for which the activity points are awarded.

    If a relevant object is created, you have to use UserActivityPointHandler::fireEvent() which expects the name of the activity point event object type, the id of the object for which the points are awarded (though the object id is not used at the moment) and the user who gets the points:

    UserActivityPointHandler::getInstance()->fireEvent(\n        'com.example.foo.activityPointEvent.bar',\n        $bar->barID,\n        $bar->userID\n);\n

    To remove activity points once objects are deleted, you have to use UserActivityPointHandler::removeEvents() which also expects the name of the activity point event object type and additionally an array mapping the id of the user whose activity points will be reduced to the number of objects that are removed for the relevant user:

    UserActivityPointHandler::getInstance()->removeEvents(\n        'com.example.foo.activityPointEvent.bar',\n       [\n                1 => 1, // remove points for one object for user with id `1`\n                4 => 2  // remove points for two objects for user with id `4`\n        ]\n);\n

    Each event that you fire in your package needs to be registered using the user notification event package installation plugin. An example file might look like this:

    userNotificationEvent.xml

    Here, you reference the user notification object type created via objectType.xml. The referenced class in the <classname> element has to implement the IUserNotificationEvent interface by extending the AbstractUserNotificationEvent class or the AbstractSharedUserNotificationEvent class if you want to pre-load additional data before processing notifications. In AbstractSharedUserNotificationEvent::prepare(), you can, for example, tell runtime caches to prepare to load certain objects which then are loaded all at once when the objects are needed.

    For daily emails ($notificationType = 'daily'), only application, template, and variables are supported. - The getEmailTitle() returns the title of the instant email sent to the user. By default, getEmailTitle() simply calls getTitle(). - The getEventHash() method returns a hash by which user notifications are grouped. Here, we want to group them not by the actual Foo object but by its parent Baz object and thus overwrite the default implementation provided by AbstractUserNotificationEvent. - The getLink() returns the link to the Foo object the notification belongs to. - The getMessage() method and the getTitle() return the message and the title of the user notification respectively. By checking the value of count($this->getAuthors()), we check if the notification is stacked, thus if the event has been triggered for multiple users so that different languages items are used. If your notification event does not support stacking, this distinction is not necessary. - The prepare() method is called for each user notification before all user notifications are rendered. This allows to tell runtime caches to prepare to load objects later on (see Runtime Caches).

    Form node dependencies allow to make parts of a form dynamically available or unavailable depending on the values of form fields. Dependencies are always added to the object whose visibility is determined by certain form fields. They are not added to the form field\u2019s whose values determine the visibility! An example is a text form field that should only be available if a certain option from a single selection form field is selected. Form builder\u2019s dependency system supports such scenarios and also automatically making form containers unavailable once all of its children are unavailable.

    If a form node has multiple dependencies and one of them is not met, the form node is unavailable. A form node not being available due to dependencies has to the following consequences:

    "},{"location":"php/api/form_builder/dependencies/#iformfielddependency","title":"IFormFieldDependency","text":"

    The basis of the dependencies is the IFormFieldDependency interface that has to be implemented by every dependency class. The interface requires the following methods:

    AbstractFormFieldDependency provides default implementations for all methods except for checkDependency().

    Using fieldId($fieldId) instead of field(IFormField $field) makes sense when adding the dependency directly when setting up the form:

    $container->appendChildren([\n    FooField::create('a'),\n\n    BarField::create('b')\n        ->addDependency(\n            BazDependency::create('a')\n                ->fieldId('a')\n        )\n]);\n

    Here, without an additional assignment, the first field with id a cannot be accessed thus fieldId($fieldId) should be used as the id of the relevant field is known. When the form is built, all dependencies that only know the id of the relevant field and do not have a reference for the actual object are populated with the actual form field objects.

    To ensure that dependent node are correctly shown and hidden when changing the value of referenced form fields, every PHP dependency class has a corresponding JavaScript module that checks the dependency in the browser. Every JavaScript dependency has to extend WoltLabSuite/Core/Form/Builder/Field/Dependency/Abstract and implement the checkDependency() function, the JavaScript version of IFormFieldDependency::checkDependency().

    All of the JavaScript dependency objects automatically register themselves during initialization with the WoltLabSuite/Core/Form/Builder/Field/Dependency/Manager which takes care of checking the dependencies at the correct points in time.

    Additionally, the dependency manager also ensures that form containers in which all children are hidden due to dependencies are also hidden and, once any child becomes available again, makes the container also available again.

    WoltLab Suite includes a powerful way of creating forms: Form Builder. Form builder allows you to easily define all the fields and their constraints and interdependencies within PHP with full IDE support. It will then automatically generate the necessary HTML with full interactivity to render all the fields and also validate the fields\u2019 contents upon submission.

    The migration guide for WoltLab Suite Core 5.2 provides some examples of how to migrate existing forms to form builder that can also help in understanding form builder if the old way of creating forms is familiar.

    "},{"location":"php/api/form_builder/overview/#form-builder-components","title":"Form Builder Components","text":"

    Form builder consists of several components that are presented on the following pages:

    1. Structure of form builder
    2. Form validation and form data
    3. Form node dependencies

    In general, form builder provides default implementation of interfaces by providing either abstract classes or traits. It is expected that the interfaces are always implemented using these abstract classes and traits! This way, if new methods are added to the interfaces, default implementations can be provided by the abstract classes and traits without causing backwards compatibility problems.

    "},{"location":"php/api/form_builder/overview/#abstractformbuilderform","title":"AbstractFormBuilderForm","text":"

    To make using form builder easier, AbstractFormBuilderForm extends AbstractForm and provides most of the code needed to set up a form (of course without specific fields, those have to be added by the concrete form class), like reading and validating form values and using a database object action to use the form data to create or update a database object.

    In addition to the existing methods inherited by AbstractForm, AbstractFormBuilderForm provides the following methods:

    Additionally, between steps 1 and 2 and after step 3, the method provides two events, createForm and buildForm to allow plugins to register event listeners to execute additional code at the right point in time. - createForm() creates the FormDocument object and sets the form mode. Classes extending AbstractFormBuilderForm have to override this method (and call parent::createForm() as the first line in the overridden method) to add concrete form containers and form fields to the bare form document. - finalizeForm() is called after the form has been built and the complete form hierarchy has been established. This method should be overridden to add dependencies, for example. - setFormAction() is called at the end of readData() and sets the form document\u2019s action based on the controller class name and whether an object is currently edited. - If an object is edited, at the beginning of readData(), setFormObjectData() is called which calls IFormDocument::loadValuesFromObject(). If values need to be loaded from additional sources, this method should be used for that.

    AbstractFormBuilderForm also provides the following (public) properties:

    "},{"location":"php/api/form_builder/overview/#dialogformdocument","title":"DialogFormDocument","text":"

    Form builder forms can also be used in dialogs. For such forms, DialogFormDocument should be used which provides the additional methods cancelable($cancelable = true) and isCancelable() to set and check if the dialog can be canceled. If a dialog form can be canceled, a cancel button is added.

    If the dialog form is fetched via an AJAX request, IFormDocument::ajax() has to be called. AJAX forms are registered with WoltLabSuite/Core/Form/Builder/Manager which also supports getting all of the data of a form via the getData(formId) function. The getData() function relies on all form fields creating and registering a WoltLabSuite/Core/Form/Builder/Field/Field object that provides the data of a specific field.

    To make it as easy as possible to work with AJAX forms in dialogs, WoltLabSuite/Core/Form/Builder/Dialog (abbreviated as FormBuilderDialog from now on) should generally be used instead of WoltLabSuite/Core/Form/Builder/Manager directly. The constructor of FormBuilderDialog expects the following parameters:

    The three public functions of FormBuilderDialog are:

    Example:

    require(['WoltLabSuite/Core/Form/Builder/Dialog'], function(FormBuilderDialog) {\nvar dialog = new FormBuilderDialog(\n'testDialog',\n'wcf\\\\data\\\\test\\\\TestAction',\n'getDialog',\n{\ndestroyOnClose: true,\ndialog: {\ntitle: 'Test Dialog'\n},\nsubmitActionName: 'saveDialog'\n}\n);\n\nelById('testDialogButton').addEventListener('click', function() {\ndialog.open();\n});\n});\n
    "},{"location":"php/api/form_builder/structure/","title":"Structure of Form Builder","text":"

    Forms built with form builder consist of three major structural elements listed from top to bottom:

    1. form document,
    2. form container,
    3. form field.

    The basis for all three elements are form nodes.

    The form builder API uses fluent interfaces heavily, meaning that unless a method is a getter, it generally returns the objects itself to support method chaining.

    "},{"location":"php/api/form_builder/structure/#form-nodes","title":"Form Nodes","text":""},{"location":"php/api/form_builder/structure/#iformnode","title":"IFormNode","text":"

    IFormNode is the base interface that any node of a form has to implement and it requires the following methods:

    The following aspects are important when working with availability:

    Availability sets the static availability for form nodes that does not change during the lifetime of a form. In contrast, dependencies represent a dynamic availability for form nodes that depends on the current value of certain form fields. - cleanup() is called after the whole form is not used anymore to reset other APIs if the form fields depends on them and they expect such a reset. This method is not intended to clean up the form field\u2019s value as a new form document object is created to show a clean form. - getDocument() returns the IFormDocument object the node belongs to. (As IFormDocument extends IFormNode, form document objects simply return themselves.) - getHtml() returns the HTML representation of the node. getHtmlVariables() return template variables (in addition to the form node itself) to render the node\u2019s HTML representation. - id($id) and getId() set and get the id of the form node. Every id has to be unique within a form. getPrefixedId() returns the prefixed version of the node\u2019s id (see IFormDocument::getPrefix() and IFormDocument::prefix()). static validateId($id) is used to check if a given id is valid. - populate() is called by IFormDocument::build() after all form nodes have been added. This method should finilize the initialization of the form node after all parent-child relations of the form document have been established. This method is needed because during the construction of a form node, it neither knows the form document it will belong to nor does it know its parent. - validate() checks, after the form is submitted, if the form node is valid. A form node with children is valid if all of its child nodes are valid. A form field is valid if its value is valid. - static create($id) is the factory method that has to be used to create new form nodes with the given id.

    TFormNode provides a default implementation of most of these methods.

    A form container object represents a container for other form containers or form field directly. Every form container has to implement the IFormContainer interface which requires the following method:

    2. TabMenuFormContainer represents the container of tab menu, while
    3. TabFormContainer represents a tab of a tab menu and

    The methods of the interfaces that FormContainer is implementing are well documented, but here is a short overview of the most important methods when setting up a form or extending a form with an event listener:

    "},{"location":"php/api/form_builder/structure/#form-field","title":"Form Field","text":"

    A form field object represents a concrete form field that allows entering data. Every form field has to implement the IFormField interface which extends IFormChildNode and IFormElement.

    IFormField requires the following additional methods:

    The object property allows having different fields (requiring different ids) that represent the same object property which is handy when available options of the field\u2019s value depend on another field. Having object property allows to define different fields for each value of the other field and to use form field dependencies to only show the appropriate field. - readValue() reads the form field value from the request data after the form is submitted. - required($required = true) and isRequired() can be used to determine if the form field has to be filled out. By default, form fields do not have to be filled out. - value($value) and getSaveValue() can be used to get and set the value of the form field to be used outside of the context of forms. getValue(), in contrast, returns the internal representation of the form field\u2019s value. In general, the internal representation is only relevant when validating the value in additional validators. loadValue(array $data, IStorableObject $object) extracts the form field value from the given data array (and additional, non-editable data from the object if the field needs them).

    AbstractFormField provides default implementations of many of the listed methods above and should be extended instead of implementing IFormField directly.

Form field validation error classes have to implement the interface IFormFieldValidationError.

    In addition to intrinsic validations like checking the length of the value of a text form field, in many cases, there are additional constraints specific to the form like ensuring that the text is not already used by a different object of the same database object class. Such additional validations can be added to (and removed from) the form field via implementations of the IFormFieldValidator interface.

    IFormDataProcessor should not be implemented directly. Instead, AbstractFormDataProcessor should be extended.

    All form data is put into the data sub-array so that the whole $parameters array can be passed to a database object action object that requires the actual database object data to be in the data sub-array.

    As mentioned above, the data in the data sub-array is intended to directly create or update the database object with. As these values are used in the database query directly, these values cannot contain arrays. Several form fields, however, store and return their data in form of arrays. Thus, this data cannot be returned by IFormField::getSaveValue() so that IFormField::hasSaveValue() returns false and the form field\u2019s data is not collected by the standard DefaultFormDataProcessor object.

    Instead, such form fields register a CustomFormDataProcessor in their IFormField::populate() method that inserts the form field value into the $parameters array directly. This way, the relevant database object action method has access to the data to save it appropriately.

    The constructor of CustomFormDataProcessor requires an id (that is primarily used in error messages during the validation of the second parameter) and callables for IFormDataProcessor::processFormData() and IFormDataProcessor::processObjectData() which are passed the same parameters as the IFormDataProcessor methods. Only one of the callables has to be given, the other one then defaults to simply returning the relevant array unchanged.

When the data processor is invoked, it checks whether the relevant entry in the $parameters array exists and voids it by removing it from the array.

    As the first step, we have to model the people we want to manage with this package. As this is only an introductory tutorial, we will keep things simple and only consider the first and last name of a person. Thus, the database table we will store the people in only contains three columns:

    1. personID is the unique numeric identifier of each person created,
    2. firstName contains the first name of the person,
    3. lastName contains the last name of the person.

    The important thing here is that Person extends DatabaseObject. Additionally, we implement the IRouteController interface, which allows us to use Person objects to create links, and we implement PHP's magic __toString() method for convenience.

    For every database object, you need to implement three additional classes: an action class, an editor class and a list class.

    This implementation of AbstractDatabaseObjectAction is very basic and only sets the $permissionsDelete and $requireACP properties.

    As WoltLab Suite Core already provides a powerful default implementation of a sortable page, our work here is minimal:

    3. The database object list class whose name is provided via $objectListClassName and that handles fetching the people from database is the PersonList class, which we have already created.

    We will go piece by piece through the template code:

    1. We include the header template and set the page title wcf.acp.person.list. You have to include this template for every page!
    2. We set the content header and additional provide a button to create a new person in the content header navigation.
    3. As not all people are listed on the same page if many people have been created, we need a pagination for which we use the pages template plugin. The {hascontent}{content}{/content}{/hascontent} construct ensures the .paginationTop element is only shown if the pages template plugin has a return value, thus if a pagination is necessary.
    4. Now comes the main part of the page, the list of the people, which will only be displayed if any people exist. Otherwise, an info box is displayed using the generic wcf.global.noItems language item. The $objects template variable is automatically assigned by wcf\\page\\MultipleLinkPage and contains the PersonList object used to read the people from database. The table itself consists of a thead and a tbody element and is extendable with more columns using the template events columnHeads and columns. In general, every table should provide these events. The default structure of a table is used here so that the first column of the content rows contains icons to edit and to delete the row (and provides another standard event rowButtons) and that the second column contains the ID of the person. The table can be sorted by clicking on the head of each column. The used variables $sortField and $sortOrder are automatically assigned to the template by SortablePage.
    5. The .contentFooter element is only shown if people exist as it basically repeats the .contentHeaderNavigation and .paginationTop element.
    6. The delete button for each person shown in the .columnIcon element relies on the global WoltLabSuite/Core/Ui/Object/Action module which only requires the jsObjectActionContainer CSS class in combination with the data-object-action-class-name attribute for the table element, the jsObjectActionObject CSS class for each person's tr element in combination with the data-object-id attribute, and lastly the delete button itself, which is created with the objectAction template plugin.
    7. The .jsReloadPageWhenEmpty CSS class on the tbody element ensures that once all persons on the page have been deleted, the page is reloaded.
    8. Lastly, the footer template is included that terminates the page. You also have to include this template for every page!

    Now, we have finished the page to manage the people so that we can move on to the forms with which we actually create and edit the people.

    Like the person list, the form to add new people requires a controller class and a template.

    The properties here consist of three types: the \u201chousekeeping\u201d properties $activeMenuItem and $neededPermissions, which fulfill the same roles as for PersonListPage, and the $objectEditLinkController property, which is used to generate a link to edit the newly created person after submitting the form, and finally $formAction and $objectActionClass required by the PHP form builder API used to generate the form.

    Because of using form builder, we only have to set up the two form fields for entering the first and last name, respectively:

    1. Each field is a simple single-line text field, thus we use TextFormField.
    2. The parameter of the create() method expects the id of the field/name of the database object property, which is firstName and lastName, respectively, here.
    3. The language item of the label shown in the ouput above the input field is set via the label() method.
    4. As both fields have to be filled out, required() is called, and the maximum length is set via maximumLength().
    5. Lastly, to make it easier to fill out the form more quickly, the first field is auto-focused by calling autoFocus().

    We will now only concentrate on the new parts compared to personList.tpl:

    1. We use the $action variable to distinguish between the languages items used for adding a person and for creating a person.
    2. Because of form builder, we only have to call {@$form->getHtml()} to generate all relevant output for the form.
    "},{"location":"tutorial/series/part_1/#person-edit-form","title":"Person Edit Form","text":"

    As mentioned before, for the form to edit existing people, we only need a new controller as the template has already been implemented in a way that it handles both, adding and editing.

    In general, edit forms extend the associated add form so that the code to read and to validate the input data is simply inherited.

    After setting a different active menu item, we have to change the value of $formAction because this form, in contrast to PersonAddForm, does not create but update existing persons.

    As we rely on form builder, the only thing necessary in this controller is to read and validate the edit object, i.e. the edited person, which is done in readParameters().

    "},{"location":"tutorial/series/part_1/#frontend","title":"Frontend","text":"

    For the front end, that means the part with which the visitors of a website interact, we want to implement a simple sortable page that lists the people. This page should also be directly linked in the main menu.

    First, let us register the page with the system because every front end page or form needs to be explicitly registered using the page package installation plugin:

    Next, we register the menu item using the menuItem package installation plugin:

    menuItem.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/menuItem.xsd\">\n<import>\n<item identifier=\"com.woltlab.wcf.people.PersonList\">\n<menu>com.woltlab.wcf.MainMenu</menu>\n<title language=\"de\">Personen</title>\n<title language=\"en\">People</title>\n<page>com.woltlab.wcf.people.PersonList</page>\n</item>\n</import>\n</data>\n

    Here, the import parts are that we register the menu item for the main menu com.woltlab.wcf.MainMenu and link the menu item with the page com.woltlab.wcf.people.PersonList, which we just registered.

    "},{"location":"tutorial/series/part_1/#people-list_1","title":"People List","text":"

    As in the ACP, we need a controller and a template. You might notice that both the controller\u2019s (unqualified) class name and the template name are the same for the ACP and the front end. This is no problem because the qualified names of the classes differ and the files are stored in different directories and because the templates are installed by different package installation plugins and are also stored in different directories.

    This class is almost identical to the ACP version. In the front end, we do not need to set the active menu item manually because the system determines the active menu item automatically based on the requested page. Furthermore, $neededPermissions has not been set because in the front end, users do not need any special permission to access the page. In the front end, we explicitly set the $defaultSortField so that the people listed on the page are sorted by their last name (in ascending order) by default.

    If you compare this template to the one used in the ACP, you will recognize similar elements like the .paginationTop element, the p.info element if no people exist, and the .contentFooter element. Furthermore, we include a template called header before actually showing any of the page contents and terminate the template by including the footer template.

    Now, let us take a closer look at the differences:

    "},{"location":"tutorial/series/part_1/#usergroupoptionxml","title":"userGroupOption.xml","text":"

    We use the existing admin.content user group option category for the permission as the people are \u201ccontent\u201d (similar the the ACP menu item). As the permission is for administrators only, we set defaultvalue to 0 and admindefaultvalue to 1. This permission is only relevant for registered users so that it should not be visible when editing the guest user group. This is achieved by setting usersonly to 1.

    As this is a package for WoltLab Suite Core 3, we need to require it using <requiredpackage>. We require the latest version (when writing this tutorial) 5.4.0 Alpha 1. Additionally, we disallow installation of the package in the next major version 6.0 by excluding the 6.0.0 Alpha 1 version.

    The most important part are to installation instructions. First, we install the ACP templates, files and templates, create the database table and import the language item. Afterwards, the ACP menu items and the permission are added. Now comes the part of the instructions where the order of the instructions is crucial: In menuItem.xml, we refer to the com.woltlab.wcf.people.PersonList page that is delivered by page.xml. As the menu item package installation plugin validates the given page and throws an exception if the page does not exist, we need to install the page before the menu item!

    This concludes the first part of our tutorial series after which you now have a working simple package with which you can manage people in the ACP and show the visitors of your website a simple list of all created people in the front end.

    The complete source code of this part can be found on GitHub.

    The existing model of a person only contains the person\u2019s first name and their last name (in additional to the id used to identify created people). To add the birthday to the model, we need to create an additional database table column using the database package installation plugin:

    files/acp/database/install_com.woltlab.wcf.people.birthday.php 
    <?php\n\nuse wcf\\system\\database\\table\\column\\DateDatabaseTableColumn;\nuse wcf\\system\\database\\table\\PartialDatabaseTable;\n\nreturn [\nPartialDatabaseTable::create('wcf1_person')\n->columns([\nDateDatabaseTableColumn::create('birthday'),\n]),\n];\n

    If we have a Person object, this new property can be accessed the same way as the personID property, the firstName property, or the lastName property from the base package: $person->birthday.

    in eventListener.xml, see below.

    As BirthdayPersonAddFormListener extends AbstractEventListener and as the name of relevant event is createForm, AbstractEventListener internally automatically calls onCreateForm() with the event object as the parameter. It is important to set <inherit>1</inherit> so that the event listener is also executed for PersonEditForm, which extends PersonAddForm.

    The language item wcf.person.birthday used in the label is the only new one for this package:

    "},{"location":"tutorial/series/part_2/#adding-birthday-table-column-in-acp","title":"Adding Birthday Table Column in ACP","text":"

    To add a birthday column to the person list page in the ACP, we need three parts:

    1. an event listener that makes the birthday database table column a valid sort field,
    2. a template listener that adds the birthday column to the table\u2019s head, and
    3. a template listener that adds the birthday column to the table\u2019s rows.

    The first part is a very simple class:

    files/lib/system/event/listener/BirthdaySortFieldPersonListPageListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\nuse wcf\\page\\SortablePage;\n\n/**\n * Makes people's birthday a valid sort field in the ACP and the front end.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class BirthdaySortFieldPersonListPageListener extends AbstractEventListener\n{\n    /**\n     * @see SortablePage::validateSortField()\n     */\n    public function onValidateSortField(SortablePage $page): void\n    {\n        $page->validSortFields[] = 'birthday';\n    }\n}\n

    We use SortablePage as a type hint instead of wcf\\acp\\page\\PersonListPage because we will be using the same event listener class in the front end to also allow sorting that list by birthday.

    As the relevant template codes are only one line each, we will simply put them directly in the templateListener.xml file that will be shown later on. The code for the table head is similar to the other th elements:

    <th class=\"columnDate columnBirthday{if $sortField == 'birthday'} active {$sortOrder}{/if}\"><a href=\"{link controller='PersonList'}pageNo={@$pageNo}&sortField=birthday&sortOrder={if $sortField == 'birthday' && $sortOrder == 'ASC'}DESC{else}ASC{/if}{/link}\">{lang}wcf.person.birthday{/lang}</a></th>\n

    For the table body\u2019s column, we need to make sure that the birthday is only show if it is actually set:

    <td class=\"columnDate columnBirthday\">{if $person->birthday}{@$person->birthday|strtotime|date}{/if}</td>\n
    "},{"location":"tutorial/series/part_2/#adding-birthday-in-front-end","title":"Adding Birthday in Front End","text":"

    In the front end, we also want to make the list sortable by birthday and show the birthday as part of each person\u2019s \u201cstatistics\u201d.

    To add the birthday as a valid sort field, we use BirthdaySortFieldPersonListPageListener just as in the ACP. In the front end, we will now use a template (__personListBirthdaySortField.tpl) instead of a directly putting the template code in the templateListener.xml file:

    templates/__personListBirthdaySortField.tpl 
    <option value=\"birthday\"{if $sortField == 'birthday'} selected{/if}>{lang}wcf.person.birthday{/lang}</option>\n

    You might have noticed the two underscores at the beginning of the template file. For templates that are included via template listeners, this is the naming convention we use.

    Putting the template code into a file has the advantage that in the administrator is able to edit the code directly via a custom template group, even though in this case this might not be very probable.

    To show the birthday, we use the following template code for the personStatistics template event, which again makes sure that the birthday is only shown if it is actually set:

    templates/__personListBirthday.tpl 
    {if $person->birthday}\n    <dt>{lang}wcf.person.birthday{/lang}</dt>\n    <dd>{@$person->birthday|strtotime|date}</dd>\n{/if}\n
    "},{"location":"tutorial/series/part_2/#templatelistenerxml","title":"templateListener.xml","text":"

    objectType.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/objectType.xsd\">\n<import>\n<type>\n<name>com.woltlab.wcf.person.personComment</name>\n<definitionname>com.woltlab.wcf.comment.commentableContent</definitionname>\n<classname>wcf\\system\\comment\\manager\\PersonCommentManager</classname>\n</type>\n</import>\n</data>\n

    The PersonCommentManager class extended ICommentManager\u2019s default implementation AbstractCommentManager:

    Additionally, we have added a new enableComments database table column to the wcf1_person database table whose value can be set when creating or editing a person in the ACP. With this option, comments on individual people can be disabled.

    Liking comments is already built-in and only requires some extra code in the PersonPage class for showing the likes of pre-loaded comments.

    The PersonPage class is similar to the PersonEditForm in the ACP in that it reads the id of the requested person from the request data and validates the id in readParameters(). The rest of the code only handles fetching the list of comments on the requested person. In readData(), this list is fetched using CommentHandler::getCommentList() if comments are enabled for the person. The assignVariables() method assigns some additional template variables like $commentCanAdd, which is 1 if the active person can add comments and is 0 otherwise, $lastCommentTime, which contains the UNIX timestamp of the last comment, and $likeData, which contains data related to the likes for the disabled comments.

    For now, the person template is still very empty and only shows the comments in the content area. The template code shown for comments is very generic and used in this form in many locations as it only sets the header of the comment list and the container ul#personCommentList element for the comments shown by commentList template. The ul#personCommentList elements has five additional data- attributes required by the JavaScript API for comments for loading more comments or creating new ones. The commentListAddComment template adds the WYSIWYG support. The attribute wysiwygSelector should be the id of the comment list personCommentList with an additional AddComment suffix.

    The page.xml file has been extended for the new person page with identifier com.woltlab.wcf.people.Person. Compared to the pre-existing com.woltlab.wcf.people.PersonList page, there are four differences:

    1. It has a <handler> element with a class name as value. This aspect will be discussed in more detail in the next section.
    2. There are no <content> elements because, both, the title and the content of the page are dynamically generated in the template.
    3. The <requireObjectID> tells the system that this page requires an object id to properly work, in this case a valid person id.
    4. This page has a <parent> page, the person list page. In general, the details page for any type of object that is listed on a different page has the list page as its parent.

    Like any page handler, the PersonPageHandler class has to implement the IMenuPageHandler interface, which should be done by extending the AbstractMenuPageHandler class. As we want administrators to link to specific people in menus, for example, we have to also implement the ILookupPageHandler interface by extending the AbstractLookupPageHandler class.

    For the ILookupPageHandler interface, we need to implement three methods:

    1. getLink($objectID) returns the link to the person page with the given id. In this case, we simply delegate this method call to the Person object returned by PersonRuntimeCache::getObject().
    2. isValid($objectID) returns true if the person with the given id exists, otherwise false. Here, we use PersonRuntimeCache::getObject() again and check if the return value is null, which is the case for non-existing people.
    3. lookup($searchString) is used when setting up an internal link and when searching for the linked person. This method simply searches the first and last name of the people and returns an array with the person data. While the link, the objectID, and the title element are self-explanatory, the image element can either contain an HTML <img> tag, which is displayed next to the search result (WoltLab Suite uses an image tag for users showing their avatar, for example), or a FontAwesome icon class (starting with fa-).

    Additionally, the class also implements IOnlineLocationPageHandler which is used to determine the online location of users. To ensure upwards-compatibility if the IOnlineLocationPageHandler interface changes, the TOnlineLocationPageHandler trait is used. The IOnlineLocationPageHandler interface requires two methods to be implemented:

    1. getOnlineLocation(Page $page, UserOnline $user) returns the textual description of the online location. The language item for the user online locations should use the pattern wcf.page.onlineLocation.{page identifier}.
    2. prepareOnlineLocation(Page $page, UserOnline $user) is called for each user online before the getOnlineLocation() calls. In this case, calling prepareOnlineLocation() first enables us to add all relevant person ids to the person runtime cache so that for all getOnlineLocation() calls combined, only one database query is necessary to fetch all person objects.

    This concludes the third part of our tutorial series after which each person has a dedicated page on which people can comment on the person.

    In addition to static boxes with fixed contents, administrators are able to create dynamic boxes with contents from the database. In our case here, we want administrators to be able to create boxes listing people. To do so, we first have to register a new object type for this person list box controller for the object type definition com.woltlab.wcf.boxController:

    <type>\n<name>com.woltlab.wcf.personList</name>\n<definitionname>com.woltlab.wcf.boxController</definitionname>\n<classname>wcf\\system\\box\\PersonListBoxController</classname>\n</type>\n

    The com.woltlab.wcf.boxController object type definition requires the provided class to implement wcf\\system\\box\\IBoxController:

    files/lib/system/box/PersonListBoxController.class.php 
    <?php\n\nnamespace wcf\\system\\box;\n\nuse wcf\\data\\person\\PersonList;\nuse wcf\\system\\WCF;\n\n/**\n * Dynamic box controller implementation for a list of persons.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Box\n */\nfinal class PersonListBoxController extends AbstractDatabaseObjectListBoxController\n{\n    /**\n     * @inheritDoc\n     */\n    protected $conditionDefinition = 'com.woltlab.wcf.box.personList.condition';\n\n    /**\n     * @inheritDoc\n     */\n    public $defaultLimit = 5;\n\n    /**\n     * @inheritDoc\n     */\n    protected $sortFieldLanguageItemPrefix = 'wcf.person';\n\n    /**\n     * @inheritDoc\n     */\n    protected static $supportedPositions = [\n        'sidebarLeft',\n        'sidebarRight',\n    ];\n\n    /**\n     * @inheritDoc\n     */\n    public $validSortFields = [\n        'firstName',\n        'lastName',\n        'comments',\n    ];\n\n    /**\n     * @inheritDoc\n     */\n    protected function getObjectList()\n    {\n        return new PersonList();\n    }\n\n    /**\n     * @inheritDoc\n     */\n    protected function getTemplate()\n    {\n        return WCF::getTPL()->fetch('boxPersonList', 'wcf', [\n            'boxPersonList' => $this->objectList,\n            'boxSortField' => $this->sortField,\n            'boxPosition' => $this->box->position,\n        ], true);\n    }\n}\n

    By extending AbstractDatabaseObjectListBoxController, we only have to provide minimal data ourself and rely mostly on the default implementation provided by AbstractDatabaseObjectListBoxController:

    1. As we will support conditions for the listed people, we have to set the relevant condition definition via $conditionDefinition.
    2. AbstractDatabaseObjectListBoxController already supports restricting the number of listed objects. To do so, you only have to specify the default number of listed objects via $defaultLimit.
    3. AbstractDatabaseObjectListBoxController also supports setting the sort order of the listed objects. You have to provide the supported sort fields via $validSortFields and specify the prefix used for the language items of the sort fields via $sortFieldLanguageItemPrefix so that for every $validSortField in $validSortFields, the language item {$sortFieldLanguageItemPrefix}.{$validSortField} must exist.
    4. The box system supports different positions. Each box controller specifies the positions it supports via $supportedPositions. To keep the implementation simple here as different positions might require different output in the template, we restrict ourselves to sidebars.
    5. getObjectList() returns an instance of DatabaseObjectList that is used to read the listed objects. getObjectList() itself must not call readObjects(), as AbstractDatabaseObjectListBoxController takes care of calling the method after adding the conditions and setting the sort order.
    6. getTemplate() returns the contents of the box relying on the boxPersonList template here:
    templates/boxPersonList.tpl 
    <ul class=\"sidebarItemList\">\n{foreach from=$boxPersonList item=boxPerson}\n        <li class=\"box24\">\n            <span class=\"icon icon24 fa-user\"></span>\n\n            <div class=\"sidebarItemTitle\">\n                <h3>{anchor object=$boxPerson}</h3>\n{capture assign='__boxPersonDescription'}{lang __optional=true}wcf.person.boxList.description.{$boxSortField}{/lang}{/capture}\n{if $__boxPersonDescription}\n                    <small>{@$__boxPersonDescription}</small>\n{/if}\n            </div>\n        </li>\n{/foreach}\n</ul>\n

    The template relies on a .sidebarItemList element, which is generally used for sidebar listings. (If different box positions were supported, we either have to generate different output by considering the value of $boxPosition in the template or by using different templates in getTemplate().) One specific piece of code is the $__boxPersonDescription variable, which supports an optional description below the person's name relying on the optional language item wcf.person.boxList.description.{$boxSortField}. We only add one such language item when sorting the people by comments: In such a case, the number of comments will be shown. (When sorting by first and last name, there are no additional useful information that could be shown here, though the plugin from part 2 adding support for birthdays might also show the birthday when sorting by first or last name.)

    Lastly, we also provide the language item wcf.acp.box.boxController.com.woltlab.wcf.personList, which is used in the list of available box controllers.

    The condition system can be used to generally filter a list of objects. In our case, the box system supports conditions to filter the objects shown in a specific box. Admittedly, our current person implementation only contains minimal data so that filtering might not make the most sense here but it will still show how to use the condition system for boxes. We will support filtering the people by their first and last name so that, for example, a box can be created listing all people with a specific first name.

    The first step for condition support is to register a object type definition for the relevant conditions requiring the IObjectListCondition interface:

    objectTypeDefinition.xml 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<data xmlns=\"http://www.woltlab.com\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://www.woltlab.com http://www.woltlab.com/XSD/5.4/objectTypeDefinition.xsd\">\n<import>\n<definition>\n<name>com.woltlab.wcf.box.personList.condition</name>\n<interfacename>wcf\\system\\condition\\IObjectListCondition</interfacename>\n</definition>\n</import>\n</data>\n

    Next, we register the specific conditions for filtering by the first and last name using this object type condition:

    <type>\n<name>com.woltlab.wcf.people.firstName</name>\n<definitionname>com.woltlab.wcf.box.personList.condition</definitionname>\n<classname>wcf\\system\\condition\\person\\PersonFirstNameTextPropertyCondition</classname>\n</type>\n<type>\n<name>com.woltlab.wcf.people.lastName</name>\n<definitionname>com.woltlab.wcf.box.personList.condition</definitionname>\n<classname>wcf\\system\\condition\\person\\PersonLastNameTextPropertyCondition</classname>\n</type>\n

    PersonFirstNameTextPropertyCondition and PersonLastNameTextPropertyCondition only differ minimally so that we only focus on PersonFirstNameTextPropertyCondition here, which relies on the default implementation AbstractObjectTextPropertyCondition and only requires specifying different object properties:

    files/lib/system/condition/person/PersonFirstNameTextPropertyCondition.class.php 
    <?php\n\nnamespace wcf\\system\\condition\\person;\n\nuse wcf\\data\\person\\Person;\nuse wcf\\system\\condition\\AbstractObjectTextPropertyCondition;\n\n/**\n * Condition implementation for the first name of a person.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license WoltLab License <http://www.woltlab.com/license-agreement.html>\n * @package WoltLabSuite\\Core\\System\\Condition\n */\nfinal class PersonFirstNameTextPropertyCondition extends AbstractObjectTextPropertyCondition\n{\n    /**\n     * @inheritDoc\n     */\n    protected $className = Person::class;\n\n    /**\n     * @inheritDoc\n     */\n    protected $description = 'wcf.person.condition.firstName.description';\n\n    /**\n     * @inheritDoc\n     */\n    protected $fieldName = 'personFirstName';\n\n    /**\n     * @inheritDoc\n     */\n    protected $label = 'wcf.person.firstName';\n\n    /**\n     * @inheritDoc\n     */\n    protected $propertyName = 'firstName';\n\n    /**\n     * @inheritDoc\n     */\n    protected $supportsMultipleValues = true;\n}\n
    1. $className contains the class name of the relevant database object from which the class name of the database object list is derived and $propertyName is the name of the database object's property that contains the value used for filtering.
    2. By setting $supportsMultipleValues to true, multiple comma-separated values can be specified so that, for example, a box can also only list people with either of two specific first names.
    3. $description (optional), $fieldName, and $label are used in the output of the form field.

    (The implementation here is specific for AbstractObjectTextPropertyCondition. The wcf\\system\\condition namespace also contains several other default condition implementations.)

    PersonInformation provides two methods, canDelete() and canEdit(), to check whether the active user can delete or edit a specific piece of information. In both cases, it is checked if the current user has created the relevant piece of information to check the user-specific permissions or to fall back to the moderator-specific permissions.

    There also two getter methods for the person, the piece of information belongs to (getPerson()), and for the user profile of the user who created the information (getUserProfile()). In both cases, we use runtime caches, though in getUserProfile(), we also have to consider the case of the user who created the information being deleted, i.e. userID being null. For such a case, we also save the name of the user who created the information in username, so that we can return a guest user profile object in this case. The most interesting method is getFormattedInformation(), which returns the HTML code of the information text meant for output. To generate such an output, HtmlOutputProcessor::process() is used and here is where we first use the associated message object type com.woltlab.wcf.people.information mentioned before.

    While PersonInformationEditor is simply the default implementation and thus not explicitly shown here, PersonInformationList::readObjects() caches the relevant ids of the associated people and users who created the pieces of information using runtime caches:

    To keep things simple here, we reuse the structure and CSS classes used for comments. Additionally, we always list all pieces of information. If there are many pieces of information, a nicer solution would be a pagination or loading more pieces of information with JavaScript.

    First, we note the jsObjectActionContainer class in combination with the data-object-action-class-name attribute, which are needed for the delete button for each piece of information, as explained here. In PersonInformationAction, we have overridden the default implementations of validateDelete() and delete() which are called after clicking on a delete button. In validateDelete(), we call PersonInformation::canDelete() on all pieces of information to be deleted for proper permission validation, and in delete(), we update the informationCount values of the people the deleted pieces of information belong to (see below).

    The button to add a new piece of information, #personInformationAddButton, and the buttons to edit existing pieces of information, .jsEditInformation, are controlled with JavaScript code initialized at the very end of the template.

    Lastly, in create() we provide default values for the time, userID, username, and ipAddress for cases like here when creating a new piece of information, where do not explicitly provide this data. Additionally, we extract the information text from the information_htmlInputProcessor parameter provided by the associated WYSIWYG form field and update the number of pieces of information created for the relevant person.

    To create new pieces of information or editing existing ones, we do not add new form controllers but instead use dialogs generated by the form builder API so that the user does not have to leave the person page.

    When clicking on the add button or on any of the edit buttons, a dialog opens with the relevant form:

    We use the WoltLabSuite/Core/Form/Builder/Dialog module, which takes care of the internal handling with regard to these dialogs. We only have to provide some data during for initializing these objects and call the open() function after a button has been clicked.

    Explanation of the initialization arguments for WoltLabSuite/Core/Form/Builder/Dialog used here:

    Next, we focus on PersonInformationAction, which actually provides the contents of these dialogs and creates and edits the information:

    When setting up the WoltLabSuite/Core/Form/Builder/Dialog object for adding new pieces of information, we specified getAddDialog and submitAddDialog as the names of the dialog getter and submit handler. In addition to these two methods, the matching validation methods validateGetAddDialog() and validateGetAddDialog() are also added. As the forms for adding and editing pieces of information have the same structure, this form is created in buildDialog() using a DialogFormDocument object, which is intended for forms in dialogs. We fire an event in buildDialog() so that plugins are able to easily extend the dialog with additional data.

    validateGetAddDialog() checks if the user has the permission to create new pieces of information and if a valid id for the person, the information will belong to, is given. The method configured in the WoltLabSuite/Core/Form/Builder/Dialog object returning the dialog is expected to return two values: the id of the form (formId) and the contents of form shown in the dialog (dialog). This data is returned by getAddDialog using the dialog build previously by buildDialog().

    After the form is submitted, validateSubmitAddDialog() has to do the same basic validation as validateGetAddDialog() so that validateGetAddDialog() is simply called. Additionally, the form data is read and validated. In submitAddDialog(), we first check if there have been any validation errors: If any error occured during validation, we return the same data as in getAddDialog() so that the dialog is shown again with the erroneous fields marked as such. Otherwise, if the validation succeeded, the form data is used to create the new piece of information. In addition to the form data, we manually add the id of the person to whom the information belongs to. Lastly, we could return some data that we could access in the JavaScript callback function after successfully submitting the dialog. As we will simply be reloading the page, no such data is returned. An alternative to reloading to the page would be dynamically inserting the new piece of information in the list so that we would have to return the rendered list item for the new piece of information.

    The process for getting and submitting the dialog to edit existing pieces of information is similar to the process for adding new pieces of information. Instead of the id of the person, however, we now pass the id of the edited piece of information and in submitEditDialog(), we update the edited information instead of creating a new one like in submitAddDialog(). After editing a piece of information, we do not reload the page but dynamically update the text of the information in the TypeScript code so that we return the updated rendered information text and id of the edited pieced of information in submitAddDialog().

    As we store the name of the user who create a new piece of information and store their IP address, we have to add event listeners to properly handle the following scenarios:

    1. If the user is renamed, the value of username stored with the person information has to be updated, which can be achieved by a simple event listener that only has to specify the name of relevant database table if AbstractUserActionRenameListener is extended:
    files/lib/system/event/listener/PersonUserActionRenameListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\n/**\n * Updates person information during user renaming.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonUserActionRenameListener extends AbstractUserActionRenameListener\n{\n    /**\n     * @inheritDoc\n     */\n    protected $databaseTables = [\n        'wcf{WCF_N}_person_information',\n    ];\n}\n
    1. If users are merged, all pieces of information need to be assigned to the target user of the merging. Again, we only have to specify the name of relevant database table if AbstractUserMergeListener is extended:
    files/lib/system/event/listener/PersonUserMergeListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\n/**\n * Updates person information during user merging.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonUserMergeListener extends AbstractUserMergeListener\n{\n    /**\n     * @inheritDoc\n     */\n    protected $databaseTables = [\n        'wcf{WCF_N}_person_information',\n    ];\n}\n
    1. If the option to prune stored ip addresses after a certain period of time is enabled, we also have to prune them in the person information database table. Here we also only have to specify the name of the relevant database table and provide the mapping from the ipAddress column to the time column:
    files/lib/system/event/listener/PersonPruneIpAddressesCronjobListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\nuse wcf\\system\\cronjob\\PruneIpAddressesCronjob;\n\n/**\n * Prunes old ip addresses.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonPruneIpAddressesCronjobListener extends AbstractEventListener\n{\n    protected function onExecute(PruneIpAddressesCronjob $cronjob): void\n    {\n        $cronjob->columns['wcf' . WCF_N . '_person_information']['ipAddress'] = 'time';\n    }\n}\n
    1. The ip addresses in the person information database table also have to be considered for the user data export which can also be done with minimal effort by providing the name of the relevant database table:
    files/lib/system/event/listener/PersonUserExportGdprListener.class.php 
    <?php\n\nnamespace wcf\\system\\event\\listener;\n\nuse wcf\\acp\\action\\UserExportGdprAction;\n\n/**\n * Adds the ip addresses stored with the person information during user data export.\n *\n * @author  Matthias Schmidt\n * @copyright   2001-2022 WoltLab GmbH\n * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>\n * @package WoltLabSuite\\Core\\System\\Event\\Listener\n */\nfinal class PersonUserExportGdprListener extends AbstractEventListener\n{\n    protected function onExport(UserExportGdprAction $action): void\n    {\n        $action->ipAddresses['com.woltlab.wcf.people'] = ['wcf' . WCF_N . '_person_information'];\n    }\n}\n

    Lastly, we present the updated eventListener.xml file with new entries for all of these event listeners:

    eventListener.xml

    The first step to support activity points is to register an object type for the com.woltlab.wcf.user.activityPointEvent object type definition for created person information and specify the default number of points awarded per piece of information:

    objectType.xml
    <type>\n<name>com.woltlab.wcf.people.information</name>\n<definitionname>com.woltlab.wcf.user.activityPointEvent</definitionname>\n<points>2</points>\n</type>\n

    Additionally, the phrase wcf.user.activityPoint.objectType.com.woltlab.wcf.people.information (in general: wcf.user.activityPoint.objectType.{objectType}) has to be added.

    The activity points are awarded when new pieces are created via PersonInformation::create() using UserActivityPointHandler::fireEvent() and removed in PersonInformation::create() via UserActivityPointHandler::removeEvents() if pieces of information are deleted.

    Lastly, we have to add two components for updating data: First, we register a new rebuild data worker

    objectType.xml
    <type>\n<name>com.woltlab.wcf.people.information</name>\n<definitionname>com.woltlab.wcf.rebuildData</definitionname>\n<classname>wcf\\system\\worker\\PersonInformationRebuildDataWorker</classname>\n</type>\n

    which updates the number of instances for which any user received person information activity points. (This data worker also requires the phrases wcf.acp.rebuildData.com.woltlab.wcf.people.information and wcf.acp.rebuildData.com.woltlab.wcf.people.information.description).

    Second, we add an event listener for UserActivityPointItemsRebuildDataWorker to update the total user activity points awarded for person information:

    PersonInformationUserActivityEvent::prepare() must check for all events whether the associated piece of information still exists and if it is the case, mark the event as accessible via the setIsAccessible() method, set the title of the activity event via setTitle(), and set a description of the event via setDescription() for which we use the newly added PersonInformation::getFormattedExcerpt() method.

    Lastly, we have to add the phrase wcf.user.recentActivity.com.woltlab.wcf.people.information, which is shown in the list of activity events as the type of activity event.

    WoltLab Suite\u2019s SCSS compiler supports adding preloading metadata to the CSS. To communicate the preloading intent to the compiler, the --woltlab-suite-preload CSS variable is set to the result of the preload() function:

    The parameters of the preload() function map directly to the preloading properties that are used within the <link> tag and the link: HTTP response header.

    The above example will result in a <link> similar to the following being added to the generated HTML:

    <link rel=\"preload\" href=\"https://example.com/images/style-1/custom/background.png\" as=\"image\" type=\"image/png\">\n

    The anchor template plugin creates a HTML elements. The easiest way to use the template plugin is to pass it an instance of ITitledLinkObject:

    {anchor object=$object}\n

    generates the same output as

    <a href=\"{$object->getLink()}\">{$object->getTitle()}</a>\n

    Instead of an object parameter, a link and content parameter can be used:

    {anchor link=$linkObject content=$content}\n

    where $linkObject implements ILinkableObject and $content is either an object implementing ITitledObject or having a __toString() method or $content is a string or a number.

    The last special attribute is append whose contents are appended to the href attribute of the generated anchor element.

    All of the other attributes matching ~^[a-z]+([A-z]+)+$~, expect for href which is disallowed, are added as attributes to the anchor element.

    If an object attribute is present, the object also implements IPopoverObject and if the return value of IPopoverObject::getPopoverLinkClass() is included in the class attribute of the anchor tag, data-object-id is automatically added. This functionality makes it easy to generate links with popover support. Instead of

    <a href=\"{$entry->getLink()}\" class=\"blogEntryLink\" data-object-id=\"{$entry->entryID}\">{$entry->subject}</a>\n

    using

    {anchor object=$entry class='blogEntryLink'}\n

    In many cases, conditional statements can be used to determine if a certain section of a template is shown:

    {if $foo === 'bar'}\n    only shown if $foo is bar\n{/if}\n

    In some situations, however, such conditional statements are not sufficient. One prominent example is a template event:

    In this example, if $foo !== 'bar', the list will not be shown, regardless of the additional template code provided by template listeners. In such a situation, hascontent has to be used:

    If the part of the template wrapped in the content tags has any (trimmed) content, the part of the template wrapped by hascontent tags is shown (including the part wrapped by the content tags), otherwise nothing is shown.

    Templates are responsible for the output a user sees when requesting a page (while the PHP code is responsible for providing the data that will be shown). Templates are text files with .tpl as the file extension. WoltLab Suite Core compiles the template files once into a PHP file that is executed when a user requests the page. In subsequent request, as the PHP file containing the compiled template already exists, compiling the template is not necessary anymore.

    "},{"location":"view/templates/#template-types-and-conventions","title":"Template Types and Conventions","text":"

    WoltLab Suite Core supports two types of templates: frontend templates (or simply templates) and backend templates (ACP templates). Each type of template is only available in its respective domain, thus frontend templates cannot be included or used in the ACP and vice versa.

    For pages and forms, the name of the template matches the unqualified name of the PHP class except for the Page or Form suffix:

    If you follow this convention, WoltLab Suite Core will automatically determine the template name so that you do not have to explicitly set it.

    For forms that handle creating and editing objects, in general, there are two form classes: FooAddForm and FooEditForm. WoltLab Suite Core, however, generally only uses one template fooAdd.tpl and the template variable $action to distinguish between creating a new object ($action = 'add') and editing an existing object ($action = 'edit') as the differences between templates for adding and editing an object are minimal.

    Foreach loops allow to iterate over arrays or iterable objects:

    <ul>\n{foreach from=$array key=key item=value}\n        <li>{$key}: {$value}</li>\n{/foreach}\n</ul>\n

    While the from attribute containing the iterated structure and the item attribute containg the current value are mandatory, the key attribute is optional. If the foreach loop has a name assigned to it via the name attribute, the $tpl template variable provides additional data about the loop:

    <ul>\n{foreach from=$array key=key item=value name=foo}\n{if $tpl[foreach][foo][first]}\n            something special for the first iteration\n{elseif $tpl[foreach][foo][last]}\n            something special for the last iteration\n{/if}\n\n        <li>iteration {#$tpl[foreach][foo][iteration]+1} out of {#$tpl[foreach][foo][total]} {$key}: {$value}</li>\n{/foreach}\n</ul>\n

    In contrast to PHP\u2019s foreach loop, templates also support foreachelse:
