WP User Tax Query

A simple drop-in plugin to support a limited version of the tax_query parameter inside a WP_User_Query.

Caveats

• You can't — and should not — supply a relation; AND is forced. (OR could be supported by replacing array_intersect with array_merge, if that's important for your use case)
• Because relations aren't supported, you also can't do nested taxonomy queries
• You can still provide an include argument on your WP_User_Query to scope your results to a specific corpus of user IDs, but nicename__(in|not_in) and login__(in|not_in) may not work (they haven't been tested)
• There may be unexpected behaviors with other query parameters
• This will multiply the number of SQL queries run on each request; you should probably cache results

Why not…

There are typically two methods floated around on the web for using a taxonomy query within a user query.

The one that seems correct leverages get_tax_sql, a function WordPress uses to generate taxonomy SQL queries for posts. However, I could not get it to behave correctly when used in tandem with WP_User_Query. I expect this relates to some way that WP_User_Query's SQL deviates from WP_Query, but in the interest of time and sanity, opted to implement it this way instead.
