Shopping Cart Issue

Postby v8don » Mon Jan 30, 2012 6:17 pm

Hi guys, I am having a slight problem with a php script shopping cart. Well, what I want to accomplish is to have products from different pages go to the same shopping cart with no script errors which is my problem. For example, the shirt page will show only the icon and quantity but no unit price, description, nor total. However, on the pants page it will show all the details of that purchase. The following script has two pages. Product page and a Product page 2 concide with Id_Item and Id_Item2 which are respectively two pages.

I get these errors when I run the code and I know its pulling from product page NOT product page 2. Everything goes to the shopping cart from product page 2.


Any help will be highly appreciated!!!!
