maar ik heb liever dat de fout uit mijn eigen script word gefixt, want eerst werkte die wel naar behorten met die cookie ;)
iig wel hartelijk bedankt voor de reactie =)
naar mijn weten zijn dit soort principes niet geliefd hier op phphulp. Men wil je helpen bij problemen en je nieuwe dingen leren...niet iets fixen waarna je het zelf nogsteeds niet begrijpt ne je volgende week terug komt met de volgende vraag
Wat zie je dan?
