Re: Session for creating a unique shopping cart for each user

why use a cookie - the $_SESSION is itself a cookie I'd code it like <php session_start() if (!isset($_SESSION['cart_id'])) { // code to get cart_id $_SESSION['cart_id'] = $cart_id; } include(db) include(products) Tore E. Mackay wrote:

Don't realy know. Here is what I have: 1. An index.php that inculdes products.php if $file=products.php. 2. products.php includes db.php that contains databse connection and the code for creating a session. 3. When I click "add product" $file=cart.php and cart.php includes the db.php file that should connect me to the db and check if there is a session. It works fine if I go passed the index.php file. Maybe it is because the index.php file has echoed information. Any idea???? Tore "Gareth Williams" <gareth@venditor.com> skrev i melding news:5C845C18-0BB1-11D8-9384-000A956BB5B4@venditor.com...

Have you already sent anything to the browser? Once the first echo has been performed, you can't send header information, as the header is sent with the first bit of text. On Friday, Oct 31, 2003, at 15:47 Europe/Amsterdam, Tore E. Mackay wrote:

Hi, I am creating a shopping cart but experiensing some difficulty in creating unique shopping carts for each user. When I try to create a session I get this error message: Warning: session_start(): Cannot send session cookie - headers already sent This is the code: if(isset($_COOKIE["cartId"])) { return $_COOKIE["cartId"]; } else { session_start(); session_register("cartId", session_id(), time() + ((3600 * 24) * 30)); return session_id(); } If I remove the session_start() and session_register it works fine, but then everyone uses the same cart and that can't be good.
