正确使用access_token for Facebook Graph API

Question

I'm extending the example.php from php-sdk in github. I'd like to list out the movies the user likes. $facebook->api('/me/movies') does not return results though the logged-in user has liked movies defined. I began to wonder if access_token was required.

Note, d is a simple print function:

<h3>Movie Likes</h3>
<?php d($facebook->api('/me/movies/?access_token=' . $session['access_token']))?>

Entering junk instead of the access_token has the same effect.

So - unclear if access_token is required or there is another problem. Secondly, if an access_token is needed is the the session access_token the one to use.

Answer 1

Facebook's SDK already handles adding the access_token param to the call, you don't need to add it yourself. Have you already authenticated the user?

Does this return something?

print_r($facebook->getSession());
