Profile page tutorial
Posted: Sun Nov 27, 2011 1:44 am
Hey guys,
I've just followed the profile tutorial and my 'edit_profile.php' doesn't seem to be updating. i.e. when I edit information and click 'update' it just refreshes without doing anything.
I've tried to check the sql query etc. and can't seem to find the error.
edit_profile.php
user.inc.php
