Hello there again, i'm using a shopping cart called plaincart, everything works perfectly but the image upload, i was told it has something to do with GD not being enabled, i'm running wamp on a local machine, using PHP version : 5.2.4 and the error message is get is:

Fatal error: Call to undefined function imagecreatetruecolor() in Z:\wamp\www\plaincart\admin\library\functions.php on line 223

the php code is:

It is because you haven't loaded the gd extension. Check php.ini

nafetski · December 28, 2007

i was told it has something to do with GD not being enabled

It's because GD isn't enabled/installed

Call to undefined function imagecreatetruecolor()

That error simply means you're trying to execute a function that hasn't been created/defined.

kenrbnsn · December 28, 2007

Your webserver needs to be restarted for the change to become effective.

Ken

starscream.pt · December 28, 2007

i have restarted wamp, still not working, maybe i should try the "classic" windows restart

kenrbnsn · December 28, 2007

No, that shouldn't be necessary. Did you edit the correct php.ini file?

Ken

starscream.pt · December 28, 2007

í edited the one inside wamp\php\php.ini

EDIT: still not working as expected :\

GingerRobot · December 28, 2007

If you're using WAMP, it should just be a case of clicking on the server icon in the system tray, then going to PHP settings=>PHP extensions and making sure that php_gd2 is checked - it should restart the server for you.

starscream.pt · December 28, 2007

helll yeah!!!! working 100% now!! i jsut hope my future webserver does support this kinda stuff, do you think i'll have any probs with that?

GingerRobot · December 28, 2007

All decent hosts that support php will have a recent version of the GD library installed.
