image uploader
Ik ben op dit moment bezig met een ajax fileuploader.
En zit met een Object met 3 methods die alleen werk als ik de uploadHandler in de zelfde pagina zet. Terwijl de methods public zijn.
Wie kan mij verder helpen?
Groeten Amorz
Dit is de upload.php

Misschien dat iemand anders een betere toelichting kan geven.
Rare vraag ik zie dat jij uit drenthe komt, ik kom uit assen.
