You can't sent any headers after some output has already been sent. I didn't take a very good look at your code, but looking at the warning you get and the position of session_start() in your code, I'd say you have to move the session_start() up. You can best start your code with session_start() and then the rest of your script. -- * R&zE: -- »»»»»»»»»»»»»»»»»»»»»»»» -- Renze Munnik -- DataLink BV -- -- E: renze@datalink.nl -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- «««««««««««««««««««««««« -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
