Hello,


I want please
to add the total weight of the products in the cart (step 1).
I tested the manipulation

https://www.prestashop.com/forums/topic/185220-modification-afficher-le-poids-total-des-produits-sur-la-page-panier/
https://www.prestash...-shopping-cart/

And I always i have 0 as the return value.

 

I could make a few changes, and it works if I go through a custom class, if I go through (add -> cart) I would always have 0 as the total return value.

If you have an idea of what I have forgotten, or what I have to check



Thank you for your help.

 

cordially
