problems with sessions

[rulian]

this is my current setup of the website i'm working on:
the index page checks if user is logged in, if not it logs the user in and creates a session:
All the other pages, i want to just make a quick check to see if the user is logged in, if they are, it shows one thing, if their not, it shows another. but on those pages with the quick check, the session variables dont work unless i specify session_start(), but when I do, even though it's the first line of code, it gives me that --Cannot send session cache limiter - headers already sent (output started at --
error message. Could it be because my pages are in frames?

Not a total authority on the subject - but I have and do use sessions.

Whatever .php page your application is on - make sure the top starts with:
<?php
--> code here including session_start();
?>

--> html code

This has to start on the very FIRST line, not any later even if the first line or two is empty, the very top of the page must start with the <?php tag.

The error message is the one you get when you put code after the very first line. I've seen it many times.

Also - you must use session_start() on every page you want to use session variables.

Lastly - if your site is in frames, that is fine - just make sure that the actual page (not the parent frame page that references your other pages) has the code above on the first line.

Hope that helps - like I said I'm not an authority, just a beginner.
