Error on deleting products

[Matteo]

Hello,

I have developed a custom module that allows purchasing specific products individually. Every time a product from that group is added to the cart, I check for it and remove any other products already in the cart.

This works fine for most products, but when I add a product with combinations (like 1 or 2 variations, so it's not too large), it leads to high memory consumption and possibly an infinite loop. I'm not sure why this is happening. Here's my code:

 

public function hookActionCartSave()
    {
        $arrayMembership = array(151029, 150995, 150996, 150997, 150998, 150999, 151000, 151001, 151077);
        // get cart id if exists
        if(isset($this->context->cart)){
            //$this->context->cart = $this->context->cart;
            //$objectCartCustom = $this->context->cart->getProducts();
            $objCart = new Cart($this->context->cookie->id_cart, $this->context->cookie->id_lang);

            $has_membership_in_cart = false;
            foreach ($arrayMembership as $id_membership) {
                $check_qnt = $objCart->containsProduct($id_membership);
                if(isset($check_qnt['quantity']) && $check_qnt['quantity'] > 0){
                    $has_membership_in_cart = true;
                }         
            }
            //echo $has_membership_in_cart;die();
            //print_r($this->context->cart->containsProduct($arrayMembership[1]));die();

            if($has_membership_in_cart){
                $has_deleted = false;
                foreach ($objCart->getProducts() as $cart_row) {
                    if(!in_array($cart_row["id_product"], $arrayMembership)){
                        $objCart->deleteProduct($cart_row["id_product"]);
                        $has_deleted = true;
                    }
                    
                }
                return $e;             
            } 
        }      
    }

p.s.

Oh, it's not $e ust because I removed the $e variable from the code.

If you have a combination you need to pass the id attribute to method

    public function deleteProduct(
        $id_product,
        $id_product_attribute = 0,
        $id_customization = 0,
        $id_address_delivery = 0

If you are doing some development of your own modules, you need to view the add, update, delete functions in the classes or controllers folder... and also look in the database to see how the indexes are set for the records. Then development will be simple.
