Magento编程添加到购物车会议期

Question

I'm trying to create an ajax script to add configurable items to the user cart. Script is below.

require_once('app/Mage.php');
umask(0);
Mage::app();

error_reporting(E_ALL);
ini_set('display_errors', 1);

$json = json_decode($_POST['json'],true);

$session = Mage::getSingleton('core/session', array('name'=>'frontend'));

if ( $_POST['form_key'] == $session->getFormKey() ) {
    $cart = Mage::getSingleton('checkout/cart')->init();
    $_product = Mage::getModel('catalog/product')->load($json['product']);
    $cart->addProduct($_product,$json)->save();
    $session->setCartWasUpdated(true);
    echo $cart->getItemsQty();
} else {
    echo "Access Denied";
}

This script gets the following through POST.

"json" = "{"super_attribute": {"76":"10","576":"82"},"qty":"1","product":"532"}"
"form_key" = "**form_key**"

It adds the item to the cart and outputs the updated quantity exactly as expected.

My problem is the frontend user session cart is never updated. Even though GetItemsQty outputs an incremented number the 'My Cart' link in the frontend is always empty.

I've even checked that $session id matches the browser session.

For future reference, this line

Mage::app();    

needed to include the following

Mage::app(5)->loadArea('frontend');

'5' being the store id
