Re: Stripped down usage of Zen Cart
For this initial implementation, I'd like to be able to just show the product page inside of a div or iframe on a page from my site. This way, I can worry about template customization down the road.
Honestly - bad way to go. Php sessions and payment modules do not like frames.
Will be much easier for you to make Zen Cart match the look of your site using the overrides to start with. You do have the ability to turn off nearly all of the functions you don't want or need through the admin.
Please do not PM for support issues: a private solution doesn't benefit the community.
Be careful with unsolicited advice via email or PM - Make sure the person you are talking to is a reliable source.
