Configure Up and Down Buttons in cart-summary.js

[Javier M.]

Hi everyone:
I am using prestashop 1.6.1.1 and basicly I have two types of products: The first group are fabrics that are sold in increments of 10 cm with a minimum quantity of 30cm. The second group are the rest of products that are sold 1 by 1 with a minimum quantity of 1.


When I am doing the queckout, the "shopping-cart-product-line.tpl" file runs "themes/default/js/cart-summary.js" javascript file. This file defines the number of units to up or down the total quantity of the product.


My problem is: if the total quantity of the product is >=30 units I want to increase the total quantity in 10 units (because the product is a fabric). If the total quantity of the product is < 30 units I want to increase the total quantity in 1 unit (because the product isn´t a fabric). In order to do this, I studied the code of the "cart-summary.js" file but I don´t find the way to do it because I don´t find the variable that contains the total quantity of the product.

Any idea how i could get it?


Thanks in advance.
