Hi
I keep gettin header errors with using sessions! I want to check that when a user logs in and a seesion is created that when the users go to a page that can only be viewed by user the session is still there and that user is still valid.
the code to create the session in my login form is
And when the user logs in and goes to the first page the code at the top of the page to check if the user is valid is :
The error im gettin is:
Cannot send session cookie - headers already sent in F:\Support on line 6 PHP Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent in F:\Support on line 6
I dont understand it because i have no spaces etc!
Thanx for any help!
