determine_current_user filter-hook . WP 3.9.0

Filters the current user.

The default filters use this to determine the current user from the request's cookies, if available.

Returning a value of false will effectively short-circuit setting the current user.

Usage

add_filter( 'determine_current_user', 'filter_function_name_2708' );
function filter_function_name_2708( $user_id ){
	// filter...

	return $user_id;
}
$user_id(int|false)
User ID if one has been determined, false otherwise.
