The problem I have is this:
I have built a shopping cart using a session. I have an addItem() function, and I was wondering if it were possible to call this function using a hyperlink. At the moment when a user clicks to add an item they are directed to the "add.php" page as below:
<a href=\"add.php?dvd_no={$row['dvd_no']}\">+</a>
I want to have my addItem() function in all shopping pages but I only want it accessed via a link. Is this possible?
Create an include file that checks $_GET for a particular variable. If it's there call addItem, if not do nothing. Then include that file in all pages that need to handle adding items.
