Question

I am using the PHP Facebook 3.0 SDK for the graph API and want a simple way to find out if there is currently an active token so that I can handle errors gracefully.

getUserAccessToken() is a protected method and so I can’t seem to access it with the facebook object. There has to be a simple way to do

if(active token){ do stuff} else{ don't}

Help anyone?

The Facebook PHP SDK Example has all the code you need for this:

<?php
require '../src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => '',
  'secret' => '',
));

$user = $facebook->getUser();

if ($user) {
  try {
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}
?>
