如何从mod_virtuemart_cart中删除单个产品

Question

I've found the solution by the link http://forum.virtuemart.net/index.php?topic=127483.0 from Virtuemart Projectleader:

if (!class_exists('VirtueMartCart')) require(VMPATH_SITE . DS . 'helpers' . DS . 'cart.php');
$cart = VirtueMartCart::getCart();
$cart->removeProductCart($yourId);

but it doesn't work. I tried to replace DS with DIRECTORY_SEPARATOR because I use Joomla 3.x but nothing changed

At the same time $cart->emptyCart() works

Joomla 3.3.6, VM 3.0.3

This is my solutions

function removeProductFromCart($product_id_to_remove){
    $cart = json_decode($_SESSION['__vm']['vmcart']);
    foreach($cart->cartProductsData as $k => $v){
        if($v->virtuemart_product_id == $product_id_to_remove) unset($cart->cartProductsData[$k]);
    }
    $_SESSION['__vm']['vmcart'] = json_encode($cart);
}
