<p><code>TagFormField</code> is a form field to enter tags.
The class implements <code>IAttributeFormField</code> and <code>IObjectTypeFormNode</code>.
Arrays passed to <code>TagFormField::values()</code> can contain tag names as strings and <code>Tag</code> objects.
The default label of instances of this class is <code>wcf.tagging.tags</code> and their default description is <code>wcf.tagging.tags.description</code>.</p>
<p><code>TagFormField</code> objects register a <a href="../validation_data/#customformfielddataprocessor">custom form field data processor</a> to add the array with entered tag names into the <code>$parameters</code> array directly using the object property as the array key.</p>
<h3 id="uploadformfield"><code>UploadFormField</code><a class="headerlink" href="#uploadformfield" title="Permanent link">#</a></h3>
<p><code>UploadFormField</code> is a form field that allows uploading files by the user.</p>
<p><code>UploadFormField</code> objects register a <a href="../validation_data/#customformfielddataprocessor">custom form field data processor</a> to add the array of <code>wcf\system\file\upload\UploadFile\UploadFile</code> into the <code>$parameters</code> array directly using the object property as the array key. Also it registers the removed files as an array of <code>wcf\system\file\upload\UploadFile\UploadFile</code> into the <code>$parameters</code> array directly using the object property with the suffix <code>_removedFiles</code> as the array key.  </p>
<p>The field supports additional settings: 
- <code>imageOnly($imageOnly = true)</code> and <code>isImageOnly()</code> can be used to ensure that the uploaded files are only images.
- <code>allowSvgImage($allowSvgImages = true)</code> and <code>svgImageAllowed()</code> can be used to allow SVG images, if the image only mode is enabled (otherwise, the method will throw an exception). By default, SVG images are not allowed.</p>
<h4 id="provide-value-from-database-object">Provide value from database object<a class="headerlink" href="#provide-value-from-database-object" title="Permanent link">#</a></h4>
<p>To provide values from a database object, you should implement the method <code>get{$objectProperty}UploadFileLocations()</code> to your database object class. This method must return an array of strings with the locations of the files.</p>
<h4 id="process-files">Process files<a class="headerlink" href="#process-files" title="Permanent link">#</a></h4>
<p>To process files in the database object action class, you must <a href="https://secure.php.net/manual/en/function.rename.php"><code>rename</code></a> the file to the final destination. You get the temporary location, by calling the method <code>getLocation()</code> on the given <code>UploadFile</code> objects. After that, you call <code>setProcessed($location)</code> with <code>$location</code> contains the new file location. This method sets the <code>isProcessed</code> flag to true and saves the new location. For updating files, it is relevant, whether a given file is already processed or not. For this case, the <code>UploadFile</code> object has an method <code>isProcessed()</code> which indicates, whether a file is already processed or new uploaded.</p>
<h3 id="userformfield"><code>UserFormField</code><a class="headerlink" href="#userformfield" title="Permanent link">#</a></h3>

<h2 id="wysiwyg-form-container">Wysiwyg form container<a class="headerlink" href="#wysiwyg-form-container" title="Permanent link">#</a></h2>
<p>To integrate a wysiwyg editor into a form, you have to create a <code>WysiwygFormContainer</code> object.
This container takes care of creating all necessary form nodes listed below for a wysiwyg editor.</p>
<div class="admonition warning">
<p class="admonition-title">When creating the container object, its id has to be the id of the form field that will manage the actual text.</p>
</div>
<p>The following methods are specific to this form container class:</p>
<ul>
<li><code>addSettingsNode(IFormChildNode $settingsNode)</code> and <code>addSettingsNodes(array $settingsNodes)</code> can be used to add nodes to the settings tab container.</li>
<li><code>attachmentData($objectType, $parentObjectID)</code> can be used to set the data relevant for attachment support.
  By default, not attachment data is set, thus attachments are not supported.</li>
<li><code>getAttachmentField()</code>, <code>getPollContainer()</code>, <code>getSettingsContainer()</code>, <code>getSmiliesContainer()</code>, and <code>getWysiwygField()</code> can be used to get the different components of the wysiwyg form container once the form has been built.</li>
<li><code>enablePreviewButton($enablePreviewButton)</code> can be used to set whether the preview button for the message is shown or not.
  By default, the preview button is shown.
  This method is only relevant before the form is built.
  Afterwards, the preview button availability can not be changed.
  Only available since WoltLab Suite Core 5.3.</li>
<li><code>getObjectId()</code> returns the id of the edited object or <code>0</code> if no object is edited.</li>
<li><code>getPreselect()</code>, <code>preselect($preselect)</code> can be used to set the value of the wysiwyg tab menu's <code>data-preselect</code> attribute used to determine which tab is preselected.
  By default, the preselect is <code>'true'</code> which is used to pre-select the first tab.</li>
<li><code>messageObjectType($messageObjectType)</code> can be used to set the message object type.</li>
<li><code>pollObjectType($pollObjectType)</code> can be used to set the poll object type.
  By default, no poll object type is set, thus the poll form field container is not available.</li>
<li><code>supportMentions($supportMentions)</code> can be used to set if mentions are supported.
  By default, mentions are not supported.
  This method is only relevant before the form is built.
  Afterwards, mention support can only be changed via the wysiwyg form field.</li>
<li><code>supportSmilies($supportSmilies)</code> can be used to set if smilies are supported.
  By default, smilies are supported.
  This method is only relevant before the form is built.
  Afterwards, smiley availability can only be changed via changing the availability of the smilies form container.</li>

<p><code>WysiwygFormField</code> is used for wysiwyg editor form fields.
This class should, in general, not be used directly but only via <code>WysiwygFormContainer</code>.
The class implements <code>IAttributeFormField</code>, <code>IMaximumLengthFormField</code>, <code>IMinimumLengthFormField</code>, and <code>IObjectTypeFormNode</code> and requires an object type of the object type definition <code>com.woltlab.wcf.message</code>.
The following methods are specific to this form field class:</p>
<ul>
<li><code>autosaveId($autosaveId)</code> and <code>getAutosaveId()</code> can be used enable automatically saving the current editor contents in the browser using the given id.
  An empty string signals that autosaving is disabled.</li>
<li><code>lastEditTime($lastEditTime)</code> and <code>getLastEditTime()</code> can be used to set the last time the contents have been edited and saved so that the JavaScript can determine if the contents stored in the browser are older or newer.
  <code>0</code> signals that no last edit time has been set.</li>
<li><code>supportAttachments($supportAttachments)</code> and <code>supportsAttachments()</code> can be used to set and check if the form field supports attachments.</li>
</ul>
<p>!!! warning "It is not sufficient to simply signal attachment support via these methods for attachments to work. These methods are relevant internally to signal the Javascript code that the editor supports attachments. Actual attachment support is provided by <code>WysiwygAttachmentFormField</code>."
- <code>supportMentions($supportMentions)</code> and <code>supportsMentions()</code> can be used to set and check if the form field supports mentions of other users.</p>
<p><code>WysiwygFormField</code> objects register a <a href="../validation_data/#customformfielddataprocessor">custom form field data processor</a> to add the relevant simple ACL data array into the <code>$parameters</code> array directly using the object property as the array key.</p>
