Changeset 31669 for trunk/src/wp-includes/user.php

Message:

Improved 'orderby' meta syntax in WP_User_Query.

Recent commits have added the ability to order query results by specific
clauses of the 'meta_query' parameter (comments [31467], posts [31312] and
[31340]). The current changeset ports the same functionality to WP_User_Query.

Also introduced is the ability to pass the value of $meta_key to 'orderby'.

The internals of WP_User_Query::prepare_users() had to be reordered
somewhat to support these changes, primarily to ensure that the meta_query
object generates its SQL clauses before the 'orderby' parameter is parsed.

See #31265.
