Hello
I'm quite new on Prestashop and someone asked me to make a modification to the function that calcul the weight to calculate the weight of the pallet, something like that :
30kg ->300kg add 12,5 kg for half of a pallet 300kg ->800kg add 25kg for one pallet etc ...
there is only one transporter but i'm struggling to find where is the function that return him the weight before he choose the tarrif. Can someone help pls
