Hi,
I know this method, but this method has a problem. It will add shipping fee for each variant. But when the variant is the samen but only the custom field is different, the system is not taking the shipping fee in account.
I have a screenshot. As you can see i have 3 products in the cart, each with a different text. The shipping fee should be 3 x 15. But its only 2 x 15 because there are only two variants.
For developing a plugin i can only find a way to modify the price per product (because the system is calculating the price each time dynamically). But that's not what i'm looking for. I need to add a fee on top of the total product price.
A perfect situation would be if i could force a option, wich wil only added
once to the cart per product.
Could you tell me the best way to approach this plugin? (just a description of the best approach)
thanks!
