HJÆLP!!! slet funktion i indkøbsvognen virker ikke
Jeg har brug for ekspert hjælp! Jeg har problemmer med at få slet funktionen af en enkelt varer til at virke i denne indkøbsvogn. Det ser ved første øjekast ud til at det virker. Når man har valgt 2 eller 3 varer i indkøbsvognen og derefter forsøger at slette en enkelt varer, så ser det ud som om at den sletter den fra kurven men når man så trykker bestil og man går til næste side står den vare som man har slettet fra kurven der også. Jeg er næsten sikker på at det er fordi at sessions variablerne ikke bliver slettet eller nulstillet. Jeg har lavet en funktion som sletter hele kurven på en gang og det virker.ER DER NOGEN SOM KAN HJÆLPE?
