Gift product per quantity

[nikpony]

Hello to all,

i need your urgent help.

I have already create a cart rule, so where a customer add a product in cart it also add a free product as a gift.

But i want, as customer increase the quantity of products that he want, also the gift to increase.

So in a real example i need when a customer has in cart 2 pieces of an Iphone, to get also 2 pieces of a charger which is the gift and not 1 as Prestashop core do.

 

I am trying to modify it in Cart.php class file but i am spending hours and i can't sleep many days now in order to fix it.

 

Any help or suggestion would be very helpful but please be as quick as you can, because we are on a hurry.

 

Thanks in advance and i am waiting your suggestions.

I think you can try to do that inside of method updateQty() of  Cart.php? every time when quantity is changed, this will be called.

Thank you shokinro for your reply...i am trying to solve it with this method but my knowledge don't help me to do it...i am writing here the part of this method in cart.php that adding a quantity in the cart for gift products...

 

If somebody could help me i would be very grateful....

if ((int)$cartRule->gift_product)
			$this->updateQty(1, $cartRule->gift_product, $cartRule->gift_product_attribute, false, 'up', 0, null, false);

		return true;
	}

I think the piece of code you listed is from addCartRule() method, this is executed when you add cart rule. and it is executed one time only.

1. Instead of 2 for the first parameter, for you will need to check the quantity of related product and use the correct quantity.

 

$this->updateQty(1,

 

2. As I mentioned you need add additional code in updateQty() so that when the related product quantity is changed, you will also need to update the gift product quantity too,

Thank you again, could you tell me how i have to call the related product quantity? Which variable is appropriated? As i told you before i am not in a good level of PHP.

Thanks in advance.

You can use $this->getProducts() to get all products in the shipping cart,

and then find out the product that is related to your gift product, and find out the quantity of that product and then update the gift product quantity.
