My if statement is always true...?

[linus72982]

I've looked at it a hundred times and can't figure out what I did wrong.  Here's what the page starts with, just a standard start to a page that is using facebook API, this isn't the problem but it gives context:

 

<?php
require ('/home/a2027775/public_html/php/facebook.php');
require ("/home/a2027775/public_html/php/ayam_Accounts.php");
$accounts = new Accounts;
$facebook = new Facebook(array(
			'appId' => 'CENSORED',
			'secret' => 'CENSORED',
			'cookie' => true,
	));
$session = $facebook->getSession();
$me = null;
if ($session) {
	try {
		$uid = $facebook->getUser();
		$me = $facebook->api('/me');
		} 
	catch (FacebookApiException $e) {
		error_log($e);
		}
}
if ($me) {
	$logoutUrl = $facebook->getLogoutUrl();
	} 
else {
	$loginUrl = $facebook->getLoginUrl();
	}
?>

 

Now, usually I can then use "if ($me) {do stuff if they're logged into facebook} else {show page with option to log in}" - it's always worked before, but then I add this code:

<?php 
	if ($me) {
		session_destroy();
		session_start();
		$_SESSION['uid']=$uid;
		if (!$accounts->isMerged($uid)) {
			header('Location: http://MYDOMAIN.com/mergeFB.php');
			}
		elseif (!isset($_SESSION['loggedIn'])) {
				$accounts->setFBUserIn($uid);
			}
		}
?>

 

and something breaks, my initial "if ($me)" always seems to figure true as no matter if I'm logged in to facebook or not, I get redirected to the mergeFB page.  Any thoughts?

 

If you need it, there is another script on the page that deals with the Facebook stuff but I don't think it has any bearing on the problem.  In any case, here it is:

 

window.fbAsyncInit = function() {
		FB.init({
		appId : '<?php echo $facebook->getAppId(); ?>',
		session : <?php echo json_encode($session); ?>,
		status : true,
		cookie : true,
		xfbml : true
		});
		FB.Event.subscribe('auth.login', function() {
			window.location.reload();
			});
		};
	(function() {
		var e = document.createElement('script');
		e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
		e.async = true;
		document.getElementById('fb-root').appendChild(e);
		}());

 

Thanks for any help.
