Fatal error: Call to undefined method FacebookRestClient::users_isAppAdded() – Updating An Old Facebook Application

If you get this error message after updating your Facebook library files:

Fatal error: Call to undefined method FacebookRestClient::users_isAppAdded()

Try changing this code:

<?php
/* ... */
       try {
	  if (!$facebook->api_client->users_isAppAdded()) {
	  		$facebook->redirect($facebook->get_add_url());
	  }
	} catch (Exception $ex) {
	  //this will clear cookies for your application and redirect them to a login prompt
	  $facebook->set_user(null, null);
	  $facebook->redirect($appcallbackurl);
	}
/* ... */
?>

With this:

<?php
/* ... */
       try {
	  if (!$facebook->api_client->users_isAppUser()) {
	  		$facebook->redirect($facebook->get_add_url());
	  }
	} catch (Exception $ex) {
	  //this will clear cookies for your application and redirect them to a login prompt
	  $facebook->set_user(null, null);
	  $facebook->redirect($appcallbackurl);
	}
/* ... */
?>

Use this at your own risk, it seems to fix the problem and I’m hoping it won’t introduce bugs in other places…
