ok i am currently having a problem with my shopping basket.
it works fine when you go to a product and select to add it to the basket, it shows on there and you can go back to shop by clicking on the products link and add as many items as you like.
but once i click on the basket link, it empties the cart. im guessing this has something to do with session as it must allocate a new id when the baset button is pressed. i have moved all the sessions to different places but to no avail. and i dont know how to set the session so that it lasts until the user closes the browser or for a set period of time.
here is the code for the basket page.
<?php
session_start();
?>
