I have a current site that has hundreds of products in sorted galleries. Customers submit email orders currently. I am testing the "Add to cart" button and it works great. data wise I only need to set "item_name", "item_number" and "amount" everything else is the same for every product. I would like to take the entire button code that PayPal generated for me and place it in a function/script and be able to call it with one line of code and pass my values. Is this doable? Need help, please.
