session_regenerate_id() needs refreshing
I have this code to create a function to generate a generate a cookie
based on session_id:

session_start();
session_regenerate_id();
session_register();
setcookie("cartId", session_id());
return session_id();
}

It is then set to $_COOKIE["cartId"]; which is used to generate a cookie
id in the database to track items etc.

I have included the session_regenerate_id(); because i need to create
a new session number if $_COOKIE["cartId"]; is not set which a log out
page i have created unsets it. It works just how i want it to exceot for one
major problem. When i go to the cart page for first time after adding an item
to it doesn't show but it will if i refresh the page.

any advice much appreciated

It may be just some bad caching on the part of your browser, try adding this code to the <head> segment:

A session must be created on request ahead of time. Usually you would want to create a session, then redirect to the next page (which would be the cart page).

Yep thanks, i got my head around it sometime this morning lol. The solution i used was to use this code in the redirect page once an order had been accepted:

setcookie("cartId",session_id(), time() - 6000);
session_start();
session_regenerate_id();
session_register();
setcookie("cartId", session_id());
header ("location:stamps.php");

this removes the current cookie cartId, regenerates the session id sets the cookie using the new session id and returns user to the home page. Now once they get to the cart the cookie "cartId" is already set so no refresh needed.
