Need help with discount and shipping (vouchers)

[kant74]

Hi,

 

I need to create vouchers with options "reduction on the order (amount)" and "create a new voucher with remaing amount" for some clients (PS 1.4.6.2).

 

I did a test but there is a problem. When the product is cheaper than the voucher, the remaing amount is deducted of the shipping cost (see screen capture).

 

 

I really need to change that and i would like that the reduction be only made on the total of products and not on the total order with shipping fees. I think that the calculation are in the classes/cart.php or discount.php but i don't know what i should change to make this work correctly. Is there some codes to add or to remove ?

 

Can someone help me ? It's very important.

 

Thanks.

Hello,

 

Discounts are calculated on total order and not total products, so you are having this problem.

 

You can find responsible function for this in /classess/Cart.php at line 853

 

public function getOrderTotal($withTaxes = true, $type = Cart::BOTH)

 

At line 948 you could change

 

$order_total -= to $order_total_products -=

 

However, you need to look into it more and check if that is enough.

 

It is a quite complicated function with many different statuses and ifs, so be careful changing it. In addition, do not forget to override it in /override/classes/ to save your changes when updating.

Thanks for your help Richard.

 

At line 948, there is :

{

$order_total -= Tools::ps_round((float)($discount->getValue(sizeof($discounts), $order_total_products, $shipping_fees, $this->id, (int)($withTaxes))), 2);

if ($discount->id_discount_type == 2)

if (in_array($discount->behavior_not_exhausted, array(1,2)))

$shrunk = true;

}

 

I changed $order_total -= Tools::ps... to $order_total_products -= Tools::ps...

but when I test, the line "total vouchers" desappear and the voucher of 5 € isn't taken any more into account.

 

It will be more difficult than i thought...
