Is it possible to add taxonomies to user profiles?

Question

I would like to know if it's possible to add taxonomies in the user profile, without hacks.

So far I have been able to add taxonomies to custom post types and all, but now I would like to add it to the user profile.

I know how to add custom fields to the user profile, but so far failed on taxonomies.

The closest I got to find a solution was: http://wordpress.org/support/topic/applying-custom-taxonomies-to-user-profiles

As a newbie trying to find it there is a better solution.

Thank you for reading and helping out.

Answer 1

The solution you linked seems about right but i can't tell if its scalable and won't crash on a large scale,

another solution would be to create a non public custom post type with no UI and to act as a "stub" post for each user and keep that post ID in a user meta table, that way you can:

• make easier queries.
• use other post features for users like: comments,tags,categories,custom taxonomies and all the functionality built for posts.
• use post based plugins on a user profile like: voting, rating, ranking...

and i believe its a much better approach.

take a look at Mike's answer to a similar question to get you started.
