Hi,
I need some help with my html/php, restricted access script.
The purpose with this script is to let users login to a members area; some with
admin permission, some with newbe permission and some with advanced
permissions. The permissions are pre-defined in the MySQL-DB with a
use_level-field in the user-table.
The different user-groups should have access to the following content:
admin - permissions to everything (for now the same as advanced)
advanced - lecture 1 and lecture 2
newbe - only lecture 1
The problem with this script is that it does not redirect the different user
groups to their repective index-pages, please help me to detect why!
