Help pls !! customize shipping cost
by desmond_ckl » Thu Sep 15, 2011 1:16 am
Hi there, I would like to customize $shippingCost in my shopping cart. I follow a tutorial from:
http://www.phpwebcommerce.com/plaincart/index.php
This tutorial using flat shipping rate, how to customize shippingCost based on the product weight ?
Example: shipping method will based on weight & place within Malaysia:
west malaysia, up to 1kg = rm9
east malaysia, up to 1kg = rm12
west malaysia, up to 2kg = rm12
east malaysia, up to 2kg = rm16
west malaysia, up to 5kg = rm18
east malaysia, up to 5kg = rm32
west malaysia, up to 10kg = rm24
east malaysia, up to 10kg = rm48
Do i need to create a new field inside my database for product weight ? is it $weight * $product_quantity ? Does anyone know how to accomplish this customization? . Please help because I am very confuse. Thank you in advanced
