title: Is it possible to send a custom parameter to FB getloginurl()?
body: <p>Something like this, so that custom_param might be used upon redirect back to the app:</p>
  <pre><code>$params = array(
  'scope' =&gt; 'email,publish_stream,user_photos,status_update',
  'redirect_uri' =&gt; base_url(),
  'custom_param' =&gt; 'bazinga',
  );
          
  // LOGGED OUT       
  $auth_url = $this-&gt;facebook-&gt;getLoginUrl($params);
  </code></pre>
  <p>A simple yay or nay would be great if you have experience in this.</p>
