Facebook API GetUser not working in mobile


Recommended Posts

I have a facebook app working at https://apps.facebook.com/inboxcupid/

When trying to log in from a mobile device, the GetUser method always return 0. It actually creates a redirect loop as the page is constantly redirected to login, return to the app page and then back to login.

It's imperative to know that this code works just fine on a desktop but fails on mobile.

Here is my code:

require_once ('facebook.php');

$config = array(
    'appId' => '*****',
    'secret' => '*****'

// Create the Facebook object
$facebook = new Facebook($config);

$login_params = array(
    'canvas' => 1,
    'scope' => 'basic_info, user_about_me, user_birthday, user_relationships, user_relationship_details, user_location, user_photos',
    'fbconnect' => 1,

$user = $facebook->getUser();

if($user) {
    try {
        $permissions = $facebook->api("/me/permissions");
        if( !array_key_exists('basic_info', $permissions['data'][0]) || !array_key_exists('user_location', $permissions['data'][0]) || !array_key_exists('user_about_me', $permissions['data'][0]) || !array_key_exists('user_birthday', $permissions['data'][0]) || !array_key_exists('user_relationships', $permissions['data'][0]) || !array_key_exists('user_relationship_details', $permissions['data'][0]) || !array_key_exists('user_photos', $permissions['data'][0]) ) {
            $login_url = $facebook->getLoginUrl($login_params); 
            echo "<script" . " type='text/javascript'" . ">top.location.href = '$login_url';</script>"; 

    } catch(FacebookApiException $e) {
        $login_url = $facebook->getLoginUrl($login_params); 
        echo "<script" . " type='text/javascript'" . ">top.location.href = '$login_url';</script>"; 
} else {
    $login_url = $facebook->getLoginUrl($login_params);
    echo "<script" . " type='text/javascript'" . ">top.location.href = '$login_url';</script>"; 

If anyone can help me figure it out I'll be thankful.

I don't know much about FB API, think the logic is the problem here though.


GetUser method always return 0



If it is returning a false then it seems to be is missing what you need to run through your methods correctly, returning a false, might want to do something like: If ($user == false){ //redirect to login }


Suggest: comment out the redirection line and echo out the variables to see if they return correctly.


Don't know if any of this will help, but worth a try.
