networks_pre_query filter-hook . WP 5.2.0

Filter the network data before the query takes place.

Return a non-null value to bypass WordPress's default network 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 network count as an int. When 'ids' === $this->query_vars['fields'], the filter should return an array of network ids. Otherwise the filter should return an array of WP_Network objects.


add_filter( 'networks_pre_query', 'filter_function_name_3275', 10, 2 );
function filter_function_name_3275( $network_data, $this ){
	// filter...

	return $network_data;
Return an array of network data to short-circuit WP's network query, the network count as an integer if $this->query_vars['count'] is set, or null to allow WP to run its normal queries.
The WP_Network_Query instance, passed by reference.
