Session / Header problems

MZaman

I'm having problems with Session and Header. The error messages that I'm getting are:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/www/intechwo/db.php:49) in /home/www/intechwo/db.php on line 41

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/www/intechwo/db.php:49) in /home/www/intechwo/db.php on line 41

Warning: Cannot modify header information - headers already sent by (output started at /home/www/intechwo/db.php:49) in /home/www/intechwo/db.php on line 42

Sometimes I get the errors and sometimes I don't. I'm quite new to PHP and have no clue where I'm going wrong. The two relevant files db.php and Products.php are attached.
Any help would be greatly appreciated.

Thank you.

You define GetCartId() in the include, but it is not called untill line 208 in products.php. This is why the error occurs.

with the session header problem try to start the session on the first page loaded on your web site before the html head tag

<?php
session_start();
?>
<html>
</html>

and also start a session on all pages needing sessions.

hope it helps let me know.

God bless

<?
ob_start();
session_start();
