I've only got the add to cart button on my product details page. I have it linked from another page as productdetails.php?ProductID=<?php echo $row_products['ProductID']; ?>
On productdetails.php on the products recordset, I have the clause: WHERE ProductID = colname
and runtime value for colname: $_GET['ProductID']
Do I need to create a second copy of the item page for items that have product options and include those clauses instead?
