This is a simple module to provide a block for use on Übercart product pages that shows other products that were bought together with the product you're viewing.
There are a few other projects that provide similar functionality:
- Ubercart Views: If you enable the "uc_views_marketing" module, there's supposed to be a "product pairs" default view that does something like this, but I couldn't get it to work, and it relies on creating a database VIEW to provide the data.
- Ubercart Products Recommender: This depends on the Recommender API, and seems to be extremely heavy-weight. I couldn't get this system working at all.
Hence, this new module. ;) It's very simple, and it only does this one thing. The query is painfully expensive, but the block is cached, so it shouldn't be much of a problem...
