Sorry this has been bugging me for a while now and I still don't understand how to fix this. someone told me
NB: You don't appear to be storing the quantity anywhere on the cart. If the user updates the quantity of "pants" to 2, and then updates the quantity of "shoes" to 2, the quantity of "pants" will be reset to 1.
and now I'm just very confused because I thought that you could get all the information from a form through a post request. I have been trying to find out how to fix this but I can't get any further. so I wanna ask it like this
how do I store the quantity from my users when they submit a form. and how will the form remember the quantity
now situation:
only updates the last option so if you have a cart like this:
item quantity price
pants 1 5.00
hat 1 4.00
shoes 1 40.00
----------------------
TOTAL 49.00
and you want to have 2 pants and 2 hats then it will do this
item quantity price
pants 1 5.00
hat 1 8.00
shoes 1 40.00
----------------------
TOTAL 53.00
a. it won't remember the quantity the user put in and just set them to one and it won't remember the quantity field and just automatically set that to one. that's where I have to store quantity so that it will remember that I guess but how do i do this??
