I'm trying to set up a shopping cart on a Drupal site, and I'm having a few difficulties. I'm quite familiar with e-commerce in general, having used osCommerce, ZenCart, Xcart, and others quite extensively, but I'm not wrapping my head around this one for some reason. I'm also a Drupal newbie, but not a CMS newbie.
Anyway...
1. I'd like to customize the /product page layout. I think I need to create a .tpl file in my theme for this, correct? How do I get the proper variables, and how do I tell it where to look for such a thing?
2. It seems to not automatically go to SSL during checkout, which seems odd to me. I'm not sure how to do this - I tried the securepages module, but as soon as I turned it on, the /admin site broke completely until I removed the module file.
3. Does anyone have any guidance on creating a payment module? I have the exact code that I use elsewhere to post a donation transaction from a form to our processor's website, but I'd like to integrate this into the Drupal structure properly. I tried using eway as a baseline, but when I do that all I get is a line in the checkout that says "Credit Card", but no place to enter one. Not that I'd want to anyway, without SSL, but...
