For anyone searching on combining Zen Cart and WordPress this thread will be one of their first stops on the way. And if they don't take the time to read all 179 pages (for some silly reason), they might think "Well, this appears to be an in depth discussion, this might be a solid choice like one of the excellent contributions from Ceon.I'll install it and then hit the forum thread if I get hung up"
The problem with WOZ is that for some very limited purposes, it does work.
As long as you don't use any the other conflicting Zen mods (or maybe I should say ANY other mods) mentioned in the course of this thread, you can have a Zen Cart that displays content from your WordPress blog.
Visitors can add items to their cart, look at some posts, while they are at the same one site, same one navigation, same one template, and the checkout is displayed throughout. This is the experience that WOZ promised.
Unfortunately, for real world situations, where your Zen and WordPress are upgraded, you add other modules to your Zen installation as you need the additional function, the WOZ mod will drive you out of your mind and it will have to be dumped.
So, WOZ does not work.
It would be great if Zen store owners could download something from the Free Software Add Ons that does this. However, if they search on "wordpress" there, they will see two contributions - WordPress On ZenCart and WordPress On ZenCart - Sideboxes Only Edition v1.0. There are no other Add Ons that combine Zen And WordPress.
Some of us still have hope that this mod, or the concept behind it, will be taken on by a contributor that could benefit from all the feedback and discussion on this thread and 'fix WOZ' so to speak.
