title: Facebook graph - empty variables
body: <p>i want to get some info about facebook user on my page, but when i try to do it - it just returns empty strings, my code:</p>
  
  <pre><code>  $request = new FacebookRequest( $session, 'GET', '/me' );
    $response = $request-&gt;execute();
    // get response
    $graphObject = $response-&gt;getGraphObject();
          $fbid = $graphObject-&gt;getProperty('id');              // To Get Facebook ID
          $fbfullname = $graphObject-&gt;getProperty('name'); // To Get Facebook full name
          $femail = $graphObject-&gt;getProperty('email');    // To Get Facebook email ID
          $flocation = $graphObject-&gt;getProperty('location');
      /* ---- Session Variables -----*/
          $_SESSION['FBID'] = $fbid;           
          $_SESSION['FULLNAME'] = $fbfullname;
          $_SESSION['EMAIL'] =  $femail;
          $_SESSION['location'] =  $flocation;
      /* ---- header location after session ----*/
  </code></pre>
