why do i get this error??

[miles_rich]

i get this error, when i attempt to set a cookie...

Warning: Cannot add header information - headers already sent by (output started at /www/htdocs/website_0.9.0/function/user_function.php:820) in /www/htdocs/website_0.9.0/function/user_function.php on line 811

why is this??
i use 3 functions.

login
make_session_id
make_cookie

once the login has been called, and checked if valid, make_session_id is called, which adds the session id to the database, then i call make_cookie, which makes the cookie, i get the error when i make the cookie.

setcookie("user_login", $value, $time_out, "".$dir_access."");

on that....

anyideas why??

Maybe because your calling sessions after you post to the session, or your headers are working against each other. I used to get that, but dont recall ow I fixed it. Sorry.
