pre_wp_is_site_initialized filter-hook . WP 5.1.0

Filters the check for whether a site is initialized before the database is accessed.

Returning a non-null value will effectively short-circuit the function, returning that value instead.

Usage

add_filter( 'pre_wp_is_site_initialized', 'filter_function_name_4228', 10, 2 );
function filter_function_name_4228( $pre, $site_id ){
	// filter...

	return $pre;
}
$pre(true/false/null)
The value to return instead.
Default: null to continue with the check
$site_id(int)
The site ID that is being checked.
