I cannot get the FB API example to work.
I have my app registered (tried both sandbox and standard mode),
I provided appId and appSecret when instantiating the facebook object, but when I click the login link I still get the error The parameter app_id is required.
My php code (in config.php I define APP_ID and APP_SECRET):
<?php
require 'config.php';
//Including facebook php sdk file
require '../classes/Facebook.php';
//Creating our application instance
$facebook = new Facebook(array(
'appId' => APP_ID,
'secret' => APP_SECRET
));
//Get User ID
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will (depending on current user state)
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
?>
