Basically I have a hierarchical list of taxonomies in Wordpress 3.0.1 associated with posts in 5 separate taxonomy groups. What I want to accomplish is to make a section where the user can submit a search query using checkboxes of the various taxonomy items, selecting one from each taxonomy group. And then after clicking submit they'd be able to see the posts that met the criteria of satisfying each taxonomy query the user selected.
For example, they select a specific artist from one group, a specific year from one group, and a specific type of artwork from another group and press 'submit'. The page would then show results of only posts from that specific artist, from that specific year, of that specific type. Essentially an advanced search based off the taxonomies. Is there any precedence in this? Does anyone have any help?
