I have been working on this for a few days. I never messed with anything to do with a cart so I am trying to understand this. Here is my web page and if you look off to the side it is not doing what I need it to do and also showing other codes: http://www.elinkswap.com/snorris/header.html. What I am trying to get done is when you are on the header.html page and you look at the cart content it should say You have 0 items. Then say you go over to the items and you want 1 and click update it should say you have 1 item in your cart. But for some reason I can not get it to work right. Here is a little bit of the code I am working with:
<?php # Script 5.2 - header.html
/*
* This page begins the HTML header for the site.
* The header also creates the right-hand column.
* This page calls session_start().
*/
// Need sessions!
session_start();
// Check for a $page_title value:
if (!isset($page_title)) $page_title = 'WoW::World of Widgets!';

I am still learning some of these things and some of this just doesnt make sense and I cant get it to work. Thanks for looking
You can count an array object, by just using
count();There is no need to loop over the array incrementing a
$itemCountvariable.Just have:
$itemCount = count( $myShoppingCart );
