Tijden veranderen
upload image
Omdat ik niet zo vindingrijk ben, maar toch op zoek ben naar een script om afbeeldingen up te loaden, heb ik een scriptje van het web geplukt. Nu komt het natuurlijk: het werkt niet echt bij mij... De foto wordt niet opgeladen of getoond.
Dit zijn de errors:
Notice: Undefined variable: imgfile in e:\programma's\easy php\www\upload\index.php on line 97
Notice: Undefined variable: imgfile in e:\programma's\easy php\www\upload\index.php on line 132
Notice: Undefined variable: imgfile in e:\programma's\easy php\www\upload\index.php on line 146
Warning: unlink(): Permission denied in e:\programma's\easy php\www\upload\index.php on line 146
... En dit script gebruik ik:
