PHP Winkelwagen
Hallo,
Ik ben bezig met het bouwen van een webshop, maar ik heb een probleem met mijn winkelwagentje.
Ik heb geprobeerd om de producten in de winkelwagen te zetten/onthouden, met session's en array's, maar blijkbaar zit er ergens een fout.
Ik had dus de vraag, wat kan ik veranderen aan mijn script? Of moet ik een hele andere methode hiervoor gebruiken?
Alvast bedankt.

Straks gaat de pastebin-inhoud verloren en heeft dit topic geen nut meer.

Ik zie in je code nergens session_start staan. Nodig om met sessies te werken.
Ja, het werkt :D. Bedankt voor de tip, ik dacht altijd dat session_start(); een andere functie had, blijkbaar niet dus :).

Is er trouwens een manier om aan te geven dat mijn probleem is opgelost? Of moet ik dit topic gewoon laten voor wat het is?
Het topic zal vanzelf wel richting naar beneden zinken. :-)
