<h2 id="subscribe-button-wcfuserobjectwatchsubscribe">Subscribe Button (WCF.User.ObjectWatch.Subscribe)<a class="headerlink" href="#subscribe-button-wcfuserobjectwatchsubscribe" title="Permanent link">#</a></h2>
<p>We have replaced the old jQuery-based <code>WCF.User.ObjectWatch.Subscribe</code> with a more modern replacement <code>WoltLabSuite/Core/Ui/User/ObjectWatch</code>.</p>
<p>The new implementation comes with a ready-to-use template (<code>__userObjectWatchButton</code>) for use within <code>contentInteractionButtons</code>:
<div class="highlight"><table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre><span></span><span class="normal">1</span></pre></div></td><td class="code"><div><pre><span></span><code><span class="cp">{</span><span class="nf">include</span> <span class="na">file</span><span class="o">=</span><span class="s1">&#39;__userObjectWatchButton&#39;</span> <span class="na">isSubscribed</span><span class="o">=</span><span class="nv">$isSubscribed</span> <span class="na">objectType</span><span class="o">=</span><span class="s1">&#39;foo.bar&#39;</span> <span class="na">objectID</span><span class="o">=</span><span class="nv">$id</span><span class="cp">}</span><span class="x"></span>
