Hallo

ik heb een vraag over een upload form

ik heb meerdere scripts geprobeerd maar krijg het niet voor elkaar dus begin te twijfelen of ik niet een instelling verkeerd heb staan ofzo, het lijkt me onmogelijk dat alle geprobeerde scripts niet werken.

nu gebruik ik deze:

ik heb in de folder waar ook index.php staat (voor het testen niet in de root) een map images gemaakt en deze op 777 gezet

als ik het uitvoer krijg ik deze fout:

Warning: imagejpeg(): Unable to open '/images/7thsunday-8046636637.jpg' for writing: No such file or directory in /var/www/vhosts/8/136894/webspace/httpdocs/website.nl/test/processupload.php on line 130 Warning: imagejpeg(): Unable to open '/images/thumb_7thsunday-8046636637.jpg' for writing: No such file or directory in /var/www/vhosts/8/136894/webspace/httpdocs/website.nl/test/processupload.php on line 177

kan iemand mij vertellen waarom dit niet werkt?

tnks!

777 moet je nooit geven aan een map, 775 is genoeg

het daadwerkelijke uploaden werkt niet.. er komt niks in de map images te staan
zal voortaan 775 geven!

ik snap niet wat je bedoelt met het veranderen van [code*]
