No, it's not. You just copied what I mentioned blindly into your code. It was not for use as is, it was just to direct you in the right direction. I suggest you first read the manual.

actualy, i've read it earlyer, but i have a lot of doubts about it, so much i cannot understand..

[pritaeas]

Just a small and brief session 101:

1. In every script you want to use session, put session_start() at the top, before any output is sent to the browser.

2. After your user is correctly logged in store it in the session like this: $_SESSION['username'] = $username;

3. In any other script, where you want to output the session user: echo $_SESSION['username']; or put it back into a variable with: $username = $_SESSION['username'];

The code you put in the above snippet is missing the single/double quotes around usernames, that's why you got the undefined constant notice.

That's it for this thread (for me).

Thanks, it's much easyer for me (as a noob) to understand this that way.
still get some errors but eventualy, i'll find a way to do it.
