title: Uncaught OAuthException: (#200), when trying to post on wall
body: <p>I want to implement a simple posting of messages from my DB to my facebook's wall. Using php-SDK:</p>
  
  <pre><code>require_once 'lib/facebook.php';
  
  $appID = 'xxx';
  $secret = 'yyy';
  $facebook = new Facebook(array(
      'appId'     =&gt;  $appID,
      'secret'    =&gt;  $secret,
  ));
  
  $user = $facebook-&gt;getUser();
  if (empty($user)) {
      header("Location: ". $facebook-&gt;getLoginUrl(array(
          'req_perms' =&gt;  'publish_stream',
      )));
      exit();
  }
  
  $params = array(
      'message' =&gt; 'Hello, every one!',
  );
  $post_id = $facebook-&gt;api('/'. $user .'/feed', 'post', $params);
  </code></pre>
  
  <p>And i have "Uncaught OAuthException: (#200) The user hasn't authorized the application to perform this action thrown in ...".</p>
  
  <p>If I'm not logged in, then when run this script, redirecting to the facebook login. Сonfirm the use of the data is not given.</p>
