Re: [PHP] Session for creating a unique shopping cart for each user

[Gareth Williams]

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.

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.

Thanx!!!

Regards
Tore
