apply_filters_ref_array( 'sites_pre_query', \WP_Site[]|int[]|int|null $site_data, WP_Site_Query $query )

Since
5.2.0, 5.6.0
Filters the site data before the get_sites query takes place.

Description

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.

Note that if the filter returns an array of site data, it will be assigned to the sites property of the current WP_Site_Query instance.

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