Sessions problems (only with AOL)

[emma57573]

I am having issues with my session script BUT its only effecting AOL clients. Its fine for everyone else. Is it something to do with my script or is this an aol bug??

 

Does anyone know of a fix? I have a client that wants to purchase an item and cant!! help!

 

This is the cart session

<? function writeShoppingCart() {
$cart = $_SESSION['cart'];
if (!$cart) {
	return '0';
} else {
	// Parse the cart session variable
	$items = explode(',',$cart);
	$s = (count($items) > 1) ? 's':'';
	return '<a href="cart.php" class="smlorange">'.count($items).' </a>';
}
}




// Process actions
$cart = $_SESSION['cart'];
$action = $_GET['action'];
switch ($action) {
case 'add':
	if ($cart) {
		$cart .= ','.$_GET['user_id'];
	} else {
		$cart = $_GET['user_id'];
	}
	break;
case 'delete':
	if ($cart) {
		$items = explode(',',$cart);
		$newcart = '';
		foreach ($items as $item) {
			if ($_GET['user_id'] != $item) {
				if ($newcart != '') {
					$newcart .= ','.$item;
				} else {
					$newcart = $item;
				}
			}
		}
		$cart = $newcart;
	}
	break;
case 'update':
if ($cart) {
	$newcart = '';
	foreach ($_POST as $key=>$value) {
		if (stristr($key,'qty')) {
			$user_id = str_replace('qty','',$key);
			$items = ($newcart != '') ? explode(',',$newcart) : explode(',',$cart);
			$newcart = '';
			foreach ($items as $item) {
				if ($user_id != $item) {
					if ($newcart != '') {
						$newcart .= ','.$item;
					} else {
						$newcart = $item;
					}
				}
			}
			for ($i=1;$i<=$value;$i++) {
				if ($newcart != '') {
					$newcart .= ','.$user_id;
				} else {
					$newcart = $user_id;
				}
			}
		}
	}
}
$cart = $newcart;
break;
}
$_SESSION['cart'] = $cart;


?>

 

The aol users have issues registering also as they cant see the catcha which makes me think its an aol thing as thats a completley different script. But I still need to find a workaround for this

 

Thanks
