A meta_query containing an `OR` relation can result in the same record matching multiple clauses, leading to duplicate results. The previous prevention against duplicates [18178] #17582 became unreliable in 4.1 when `WP_Meta_Query` introduced support for nested clauses. The current changeset adds a new method `WP_Meta_Query::has_or_relation()` for checking whether an `OR` relation appears anywhere in the query, and uses the new method in `WP_User_Query` to enforce distinct results as necessary. Props maxxsnake. Fixes #32592. git-svn-id: https://develop.svn.wordpress.org/trunk@32713 602fd350-edb4-49c9-b593-d223f7449a82 |
