do_action_ref_array( 'pre_get_posts', WP_Query $this )

Fires after the query variable object is created, but before the actual query is run.


Description

Note: If using conditional tags, use the method versions within the passed instance (e.g. $this->is_main_query() instead of is_main_query()). This is because the functions like is_main_query() test against the global $wp_query instance, not the passed one.


Parameters

$this

The WP_Query instance (passed by reference).
