Hi people I'm sorry about all my threads, I am pretty new to php ect...
I have this piece of code:


setcookie("in", 1, time()+3600);
// Start hidden page
header("Location: http://cowly.co.uk/staff/logged.htm");

Which are lines 24, 25, 26.
I get this error when trying to log in...

Warning: Cannot modify header information - headers already sent by (output started at /home/cowly1a/public_html/staff/index.php:6) in /home/cowly1a/public_html/staff/index.php on line 24

Warning: Cannot modify header information - headers already sent by (output started at /home/cowly1a/public_html/staff/index.php:6) in /home/cowly1a/public_html/staff/index.php on line 26

Help will be appreciated and repped, or put on my rep list.

It is because you can't use headers after you've already send data to the browser.

you need to move ob_start to the top. cookie info is stored in the packet's header, when you start outputting contnet, the header gets sent (therefore you cannot ammend/add to it). by putting ob_start at the top, yuo buffer the output and send it once the server finishes parsing the file (so practically, the header doesn't get sent off.. and you can mess about with it).
