Question

$facebook = new Facebook($configs);
$uid = $facebook->getUser();

if($uid) {
    // Do stuffs
} else {
    $loginUrl = $facebook->getLoginUrl();

    echo('<script> top.location.href = "' . $loginUrl . '";</script>');
}
?>

All work perfectly, but, if user are not logged, the script redirect to Facebook which ask login. When login, the script redirect to my application external url http://mywebsite.com/facebook-app and not my apps.facebook.com/myappid.

Answer 1

Check that the URLs on the apps settings page on Facebook Developer are correct. If your app is of the ‘App on Facebook’ type, check that

Canvas URL
Secure Canvas URL

are correct.

If it’s a ‘Mobile Web’ app, check

Mobile Web URL

and so on depending on the type of app.
