If you post some code, we could help you quicker ! :p

probably something printed before session_start();

session_start(); always first...

otherwise give some code... 😃

Or search the forums for Cannot add header information headers already sent. There is also a section on this error in the PHP Manual's FAQ (Volume VII; Chapter 50).

As far as I know, this error message appears (as said above) only when output was sent, before the session_start();
open your page with

<?php
    session_start();
?>

you can now do anything you want, or code everything you want. Create session variables with session_register(). For example session_register("ThisIsASessionVar");

now you can change the value of the session averywhere in your code.

$ThisIsASessionVar = "My First Session Worked!";

The masters have said it all. Always ensure that:

session_start(); is the first statement after your <?php tag.

You can then proceed by registering you session variables has mentioned above.

Again always give some codes
