Sessions seem like voodoo at first, but, once you understand what's really going on, it's actually not that complicated. Here are some links to check out:

Each user to your site has a custom session set up for them when you issue a session_start() in PHP. The name of this session file is either stored in a Cookie (if the user has cookies enabled) or is passed from page to page on the URL (which makes the URLS long and ugly). Using PHP's built in session functions, you can store data in those server session files just by setting variables within the $_SESSION[] array, like this: session_start(); $_SESSION['username'] = 'Bob'; $_SESSION['accesslevel'] = 2; Because the session file follows the user around from page to page, you can access the above data within your PHP scripts at any time... session_start(); echo "Hi there ".$_SESSION['username'].", welcome back!"; That's a very brief overview. The above links provide better explanations. Monty > From: [EMAIL PROTECTED] (Daniel J.
