RE: [PHP-DB] RE: regarding session

thanks ! its working fine now. but again one question. (simple one , but i couldnt find the answer ) :-( after user logs in, on each page i check whether valid session has been created. if not, then i wish to redirect to the login page. doing as, if(!session_is_registered("UserID")) { header("Location: login.php"); } else { ... some other stuff, if user is logged in... } here, while redirecting to login.php , its giving "Cannot add header information - headers already sent " error. whats wrong in the header function im using? or what changes i need to do in login.php to get it done?? thanks in advance :-) smita.
