Using PS4, I need to add more information to the product information pages. I can add fields in the database to contain the information that I need, no problem. What I haven't figured out yet is the structure of the pages in order to do some edits.
What I want to do is to add fields in the products. Object is to add "If you like this product, you may also be interested in these." So three fields that contain another product id, code the page to show the thumbnail from that id, a link to that product id page. But where in this system would I do this? Lots of templates and includes.
Other elements I want to add are "Review this product" using a new table etc.
Is there a "map" of how all these elements work together so I can do more customization? Is what I want to do even possible?
