sites_pre_query ›

apply_filters_ref_array( 'sites_pre_query', array( $site_data, &$this )
Parameters: (2)
  • (array|int|null) $site_data Return an array of site data to short-circuit WP's site query, the site count as an integer if `$this->query_vars['count']` is set, or null to run the normal queries.
    Required: Yes
  • (WP_Site_Query) $this The WP_Site_Query instance, passed by reference.
    Required: Yes
Defined at:

Filters the site data before the get_sites query takes place.

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

The expected return type from this filter depends on the value passed in the request query vars:

  • When $this->query_vars['count'] is set, the filter should return the site count as an integer.
  • When 'ids' === $this->query_vars['fields'], the filter should return an array of site IDs.
  • Otherwise the filter should return an array of WP_Site objects.


$site_data = apply_filters_ref_array( 'sites_pre_query', array( $site_data, &$this ) );
