title: Joomla 1.5 com_user and importing user plugins like Joomla 1.6 and above
body: <p>When accessing com_users component in Joomla 1.6 and 1.7 on front-end the application automatically imports all plugins from 'user' group. Obviously it is very useful if one doesn't want to create a component to simply pass some variables to a plugin.</p>
  
  <p>Ok. let's make it simplier:</p>
  
  <ol>
  <li>User gets an activation link: <a href="http://example.com/index.php?option=com_users&amp;task=edit&amp;emailactivation=1&amp;u=63&amp;d077b8106=1" rel="nofollow">http://example.com/index.php?option=com_users&amp;task=edit&amp;emailactivation=1&amp;u=63&amp;d077b8106=1</a> and clicks it.</li>
  <li>Of course the component will omit <strong>emailactivation</strong> and other params simply displying "Edit Profile Form" (or login form for guests).</li>
  <li>Then JApplication imports all plugins from '<strong>user</strong>' group, which triggers __constructors</li>
  </ol>
  
  <p>Basically, with plugin's <strong>__constructor</strong> one can set up simple action like this one below:</p>
  
  <pre><code>class plgUserAccountactivation extends JPlugin
  {
      public function __construct(&amp; $subject, $config)
      {
          parent::__construct($subject, $config);
  
          if(isset($_GET['emailactivation'])) {
              // check token
              // activate account, email or whatever
              // redirect with message
          }
      }
  }
  </code></pre>
  
  <p>Wow! It works, it is not necessary to create a whole controller to handle one simple task.</p>
  
  <p>But hold on a minute...</p>
  
  <ul>
  <li>In the link change index.php?option=com_users to index.php?option=com_user</li>
  <li>And let's try on Joomla 1.5...</li>
  </ul>
  
  <p>Hey, hey, nothing happens com_user didn't import anything at all and __constructor wan't called.</p>
  
  <p>I am very troubled by this in Joomla 1.5 and I don't feel like writing whole component. </p>
  
  <p>Should anybody have some bright idea, please let me know.</p>
  
  <p><strong>Edit:</strong>
  I've solved my problem by sending the link in the following form:</p>
  
  <blockquote>
    <p>http:/example.com/index.php?option=com_user&amp;<strong>task=logout</strong>&amp;emailactivation=1&amp;u=63&amp;d077b8106=1</p>
  </blockquote>
  
  <p>This way user plugins are included and __constructors are executed. But this is so frivolous as <strong>task=logout</strong> doesn't really encourage to click in the link.</p>
