Query component

The Query component includes the following:

  • WP_Query, WP_User_Query, and WP_Comment_Query. These are the three APIs that WordPress offers for constructing complex data queries.
  • Template functions used to deterimine the kind of page currently being requested. These are the is_*() functions – is_month(), is_single(), and so on.
  • WP_Meta_Query, WP_Tax_Query, and WP_Date_Query. These are helper classes, used by the main query classes as well as third-party plugins, to construct SQL clauses related to metadata, taxonomy terms, and date ranges.

Projects for future releases

  • Improved caching. Most queries are currently cached at the level of individual items (posts, users, etc), but the IDs that result from the query are uncached. See #22176 for an example.
  • The query classes, and particularly WP_Query, contain lots of legacy code that causes problems in edge cases, makes unit testing difficult, and so on. There are various initiatives underway to clean up some of these problems. See #30911 for an example related to post_status.
