Question

I am using php-sdk for showing facebook information of the user. I have successfully shown the user profile info but while fetching any album or photos I am getting the blank data to me. I read the photos requires access_token.
Also if I put this query in the facebook graph api explorer it showing me the perfect result. So query is right may be my way of passing the url is wrong.

I am not getting the issue.
Please help.
‘;
$app_secret = ”;
$my_url = ”;

          $config = array(
            'appId' => '<appid>',
            'secret' => '<appsecrete>',
           );

            $facebook = new Facebook($config);
            $user_id = $facebook->getUser();

            $code = $_REQUEST["code"];
            if($user_id) {
             //auth user
             if(empty($code)) {
                $dialog_url = 'https://www.facebook.com/dialog/oauth?client_id=' 
                    . $app_id . '&redirect_uri=' . urlencode($my_url) ;
                    echo("<script>top.location.href='" . $dialog_url . "'</script>");
              }

              //get user access_token
              $token_url = 'https://graph.facebook.com/oauth/access_token?client_id='
                . $app_id . '&redirect_uri=' . urlencode($my_url) 
                . '&client_secret=' . $app_secret 
                . '&code=' . $code;
              $access_token = file_get_contents($token_url);

             $fql_query_url = 'https://graph.facebook.com/'.'fql?q=SELECT+pid,src_small+FROM+photo+WHERE+aid+IN+(SELECT+aid+FROM+album+WHERE+owner=+me())&'.$access_token;
             $fql_query_result = file_get_contents($fql_query_url);
             $fql_query_obj = json_decode($fql_query_result, true);


          //display results of fql query
          echo '<pre>';
          print_r("query results:");
          print_r($fql_query_obj);
          echo '</pre>';

}

One parameter needs to be add for $dialog_url variable which is ‘scope’ which defines permissions to be given for application

$dialog_url = 'https://www.facebook.com/dialog/oauth/?client_id='.$app_id.'&redirect_uri='.urlencode($my_url).'&scope=user_photos';
                    echo("<script>top.location.href='" . $dialog_url . "'</script>");
