posts_pre_query хук-фильтр . WP 4.6.0

Filters the posts array before the query takes place.

Return a non-null value to bypass WordPress's default post queries.

Filtering functions that require pagination information are encouraged to set the found_posts and max_num_pages properties of the WP_Query object, passed to the filter by reference. If WP_Query does not perform a database query, it will not have enough information to generate these values itself.
