WP_Query::parse_query() WP 1.5.0

Parse a query string and set query type booleans.

Это метод класса: WP_Query

  • C версии 4.2.0 Introduced the ability to order by specific clauses of a $meta_query, by passing the clause's array key to $orderby.
  • C версии 4.4.0 Introduced $post_name__in and $title parameters. $s was updated to support excluded search terms, by prepending a hyphen.
  • C версии 4.5.0 Removed the $comments_popup parameter. Introduced the $comment_status and $ping_status parameters. Introduced RAND(x) syntax for $orderby, which allows an integer seed value to random sorts.
  • C версии 4.6.0 Added 'post_name__in' support for $orderby. Introduced the $lazy_load_term_meta argument.
  • C версии 4.9.0 Introduced the $comment_count parameter.
  • C версии 5.1.0 Introduced the $meta_compare_key parameter.
