WP_Meta_Query::has_or_relation()
Checks whether the current query has any OR relations.
In some cases, the presence of an OR relation somewhere in the query will require the use of a DISTINCT or GROUP BY keyword in the SELECT clause. The current method can be used in these cases to determine whether such a clause is necessary.
Method of the class: WP_Meta_Query{}
No Hooks.
Return
true|false
. True if the query contains any OR relations, otherwise false.
