All I want to do is to integrate zen cart into my website. My website is NOT entirely a store, but has a store aspect to it. Rather than integrating my website INTO Zen Cart, I would rather go the other way.
Zen Cart isn't designed to do that. There are so many things that need to work together and carry php sessions that it is not really practical. You can make Zen Cart look like the rest of your site but it isn't made to be a "module" of something else.
