title: Tagging friends in status updates from Facebook API
body: <p>I recently came across <a href="http://www.insidefacebook.com/2009/09/14/developer-tip-how-to-tag-friends-in-status-updates-from-your-app-undocumented/" rel="nofollow">this blog post</a> that said that it's possible to tag someone in a status update from a Facebook app (= from the API):</p>
  
  <p>However, it doesn't seem to work for me.</p>
  
  <p>It tried it in three different ways:</p>
  
  <pre><code>$post = $facebook-&gt;api('/me/feed', 'post', array(
      'access_token' =&gt; $session['access_token'],
      'message' =&gt; 'Hello @[562372646:Lionel Cordier], how are you?'
  ));
  </code></pre>
  
  <p>or</p>
  
  <pre><code>$access_token = $session['access_token'];
  $message = 'Hello @[562372646:Lionel Cordier], how are you?';
  $curl_post = 'access_token='.$access_token.'&amp;message='.$message;
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/me/feed');
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $curl_post);
  $data = curl_exec($ch);
  curl_close($ch);
  </code></pre>
  
  <p>or</p>
  
  <pre><code>$access_token = $session['access_token'];
  $message = 'Hello @[562372646:Lionel Cordier], how are you?';
  $curl_post = 'access_token='.$access_token.'&amp;status='.$message;
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'https://api.facebook.com/method/users.setStatus');
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $curl_post);
  $data = curl_exec($ch);
  curl_close($ch);
  </code></pre>
  
  <p>But nothing works. The result I have is "<em>Hello @[562372646:Lionel Cordier], how are you?</em>" on my wall.</p>
  
  <p>But if I type "<em>Hello @[562372646:Lionel Cordier], how are you?</em>" directly in Facebook, it works correctly.</p>
  
  <p><strong>What am I doing wrong?</strong></p>
