Hjælp til file upload
Hej.I dette spm.
http://www.eksperten.dk/spm/87610
fandt jeg de to nedenstående filer, men jeg kan ikke rigtig få det til at virke. Der er en masse \ i de to filer, og Dreamweaver CS3 kan så ikke rigtig finde ud af det.
Jeg har så fjernet dem, men jeg er nok kommet til at fjerne nogen der ikke skulle ?
Nogen der kan gennemskue sådan noget her ?
Første fil er upload.php som er formularen. Gennemse virker.

// can not figure out what type of file it is, you can

// a file with the same name as another file in the

Men så er der filen fileupload.class og den siger DW at den kan den ikke rette i og har ikke farvekode på kommandoerne. Noget uoverskueligt.

Jeg bliver meget glad, hvis det kan komme til at virke.
