I am trying to experiment with the new facebook authentication system, and I can't getthe login to work.
I'm getting the following error message:
API Error Code: 100
API Error Description: Invalid parameter
Error Message: next is not owned by the application.
The url that is being sent to facebook is:
Note that the 'Next' variable in the url is:
next=http%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26cb%3Df357eceb0361a8a%26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx
Any ideas what could be going wrong? All I've done is copy and paste the facebook login demo code from facebook's website:
<?php
define('FACEBOOK_APP_ID', 'your application id');
define('FACEBOOK_SECRET', 'your application secret');
function get_facebook_cookie($app_id, $application_secret) {
$args = array();
parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
ksort($args);
$payload = '';
foreach ($args as $key => $value) {
if ($key != 'sig') {
$payload .= $key . '=' . $value;
}
}
if (md5($payload . $application_secret) != $args['sig']) {
return null;
}
return $args;
}
$cookie = get_facebook_cookie(FACEBOOK_APP_ID, FACEBOOK_SECRET);
?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"

<?php if ($cookie) { ?>
Your user ID is <?= $cookie['uid'] ?>
<?php } else { ?>
<fb:login-button></fb:login-button>
<?php } ?>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({appId: '<?= FACEBOOK_APP_ID ?>', status: true,
cookie: true, xfbml: true});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
</script>
</body>
</html>
Thanks for the help!
