Don't share taxonomies between users and posts

Hello,
I’ve just seen this plug-in and the possibilities seem to be very interesting. But I need to share taxonomies between any type of post and users.

I Think there is a way for WordPress to distinguish whether the object_id in the wp_term_relationships table is a post ID or a user ID : it need that WordPress see wp_term_taxonomy table where there is object type. It could do it with a SQL WHERE clause.

And it need that the string “user” be reserved to the users and doesn’t used for a post type named “user”…

[edit] In fact, that’s right wp_term_taxonomy haven’t field to know witch table linked to… A field should be added with the table concerned… In MERISE Method we must create a new specific relation between user and wp_term_taxonomy tables…

I suppose it’s possible to filter the WP Query to inject your WHERE clause but this would be a bad idea. This problem is better avoided altogether by creating new taxonomies for users. In other words, do this:

register_taxonomy('mytaxonomy','post', $args);
register_taxonomy('user_mytaxonomy','user', $args);

NOT:

register_taxonomy('mytaxonomy',array('post','user), $args);

Here is another plugin with User Taxonomy option, instead of manually registering you can register directly.
