I’m pleased to announce a nice little addition to one of my client’s sites.  Espec.com now has a product comparison tool that runs off the ExpressionEngine backend.

I’m considering a more detailed writeup of how it works down the road - but in a nutshell the select-boxes are dynamically populated by weblog:entries tags, a bit of Javascript assembles a URL from the entry_id of the selections, and the results are constructed with weblog:entries tags reading the entry_id’s from URL segments.

The nice part is that the results pages don’t use any cookies - and hence are able to be bookmarked by users, or sent via email by Espec sales people to prospective clients.
