Kruimeltjes zijn weer op :9

Je script heeft al HTML output voordat je iets met de headers wil doen.

Hallo, welkom @ GoT

Got is geen helpdesk voor je vragen zoals "Wie weet wat hier mis mee is", maar een discussieforum. Wat heb je zelf zoal sgeprobeerd om het te laten functioneren en te doen :?

Welkom in P&W: FAQ en Beleid *updated: 05-07* is misschien ook wel handig voor je :)
