Really struggling with a ecommerce solution that has become more customized than I ever thought. I will try to explain.
Im adding extra cart infomation to each added product in cart on a custom button click. On each add to cart click, a custom input field has a counter for each added item. That part works pretty good.
The problem is, when removing a cart item in mini cart I need to remove x quantity of products within the custom input field. So I can keep track on how many are left and avaiable after remove.
Also when the single product page is loading I need to fill the custom input field with quantity of the cart, so it is correct when adding products again...
