[Solved] "persistent" Cart That Doesn't Empty After Payment?

[mavix91]

Hello,

 

I've been going through the Prestashop code trying to figure out how to make the cart contents persist after an order payment has been made, with no luck.

 

The way I understand it, it would appear that once an order has been associated with a cart, it is no longer available as the customer's shopping cart (and the default cart is thus returned to "empty").

 

Based on the above then, I assume it would be best to duplicate the cart associated with the order to a new cart associated to the customer at some stage during the order, which will then repopulate the shopping cart as soon as the payment is processed.

 

Would this be the best way to do it? And where/how would I make this change?

For what it's worth, I tried adding the following code to controllers/front/OrderConfirmationController.php, before the return in displayOrderConfirmation(), which I figured was the last step in the order process and would be the best place to duplicate the cart:

$cart = new Cart($this->id_cart);
$this->context->cart = $cart->duplicate();

However, this doesn't seem to do anything. I've also tried placing it elsewhere in various order controllers functions with no luck.

 

Any ideas on what I'm doing wrong?

Solved, as follows:

 

1. Duplicate cart once order complete (Controllers/front/displayOrderConfirmation, before return in displayOrderConfirmation, insert:

    $cart = new Cart($this->id_cart);
    $this->context->cart = $cart->duplicate();

2. Under FrontController->init replace:

           if (!isset($cart) || !$cart->id) {
            $cart = new Cart();

            $cart->id_lang = (int)$this->context->cookie->id_lang;
            $cart->id_currency = (int)$this->context->cookie->id_currency;
            $cart->id_guest = (int)$this->context->cookie->id_guest;
            $cart->id_shop_group = (int)$this->context->shop->id_shop_group;
            $cart->id_shop = $this->context->shop->id;
            if ($this->context->cookie->id_customer) {
            $cart->id_customer = (int)$this->context->cookie->id_customer;
            $cart->id_address_delivery = (int)Address::getFirstCustomerAddressId($cart->id_customer);
            $cart->id_address_invoice = (int)$cart->id_address_delivery;
            } else {
            $cart->id_address_delivery = 0;
            $cart->id_address_invoice = 0;
            }

            // Needed if the merchant want to give a free product to every visitors
            $this->context->cart = $cart;
            CartRule::autoAddToCart($this->context);
        }

    with

        if (!isset($cart) || !$cart->id) {
            $cart = new Cart();
            $cart = $this->context->customer->getLastCartObjectES();  

            // Needed if the merchant want to give a free product to every visitors
            $this->context->cart = $cart;
            CartRule::autoAddToCart($this->context);
        }

3. Add the following function to the Customer class:

        public function getLastCartObjectES()
        {
        $carts = Cart::getCustomerCarts((int)$this->id, false);
        if (!count($carts)) {
            return false;
        }
        
        $cart = array_shift($carts);
        $cart = new Cart((int)$cart['id_cart']);
        return $cart;
        }
