Here is the code I used in db.php:

<?php
$dbServer = "localhost";
$dbUser = "root";
$dbName = "travel";
function ConnectToDb($server, $user, $database)
{
$s = @mysql_connect($server, $user);
$d = @mysql_select_db($database, $s);
if(!$s || !$d)
return false;
else
return true;
}
function GetCartId()
{
if(isset($_COOKIE["cartId"]))
{
return $_COOKIE["cartId"];
}
else
{
session_start();
setcookie("cartId", session_id(), time() + ((3600 * 24) * 30));
return session_id();
}
}
?>

try to put your session_start() on the very top of code. right after <?php.
