Shipping costs per weight of each product

[tadde0]

Hi,

 

I need to customize the cart (maybe the carrier module, too) and I'm struggling to figure out how to do that. I hope someone can help.

 

Here's the problem: I have many voluminous products in my catalog, so I need to ship them in separate boxes. The carrier obviously calculates the shipping cost by the weight range of each product (they also have different shipping rates for different destinations).

I thought that PS could do that, so I set the prices for each weight range, but then I realized it uses the cart total weight instead, so the result is not the same.

 

As I looked for a solution in the forum, I found this old topic that seemed to work in older versions of PS:

http://www.prestashop.com/forums/topic/140687-shipping-costs-per-weight-of-each-product-not-cart-total/.

I'm using Prestashop 1.5.6.1.

 

Does anybody know how to solve this problem?

 

Thanks.

You will need to develop custom shipping module and use getPackageShippingCost() or getOrderShippingCost() method to calculate shipping cost for each product and get the total shipping cost

But I guess it will be better to use getPackageShippingCost() method, because this method already have a parameter (in the 3rd parameter) which containing all products data within the existing cart.
 

.

/*
 * @param object $cart An existing object cart
 * @param float $shipping_cost The previous shipping cost which has been calculated for the cart
 * @param array $products List of product concerned by the shipping
 */
public function getPackageShippingCost($cart, $shipping_cost, $products)
{
      // Do shipping calculation here
}

.

You can calculate shipping cost for each product according to its weight, but you can not use different shipping address for 1 object cart, because object cart can only hold 1 shipping address
