Re: Session Problem

Darrell,

Can you post some of your code? Otherwise we can only guess as to why
it isn't working, and even that would probably be a long shot.

Re: Session Problem

Ok. I've listed three files below. admin.php is where the user enters their
username and password. admin2.php is where it checks the username and
password and displays the admin section and addnews.php allows you to add
news to the site. It's when I try to add news when it sometimes works and
sometimes doesn't. When I click add news half of the time it shows the add
news section and half of the time it doesn't. This is because uname isn't
set when it should be (and is half of the time). If you want to see the site
go to http://linrar.sourceforge.net/index2.php (I will rename it index.php
once the site works).
