WordPress Redirect to Previous Page on Login

function-alt.php

<?php
function my_login_redirect( $redirect_to, $request, $user ) {
    $redirect_to = home_url() . '/members/';

    return $redirect_to;
}
add_filter( 'login_redirect', 'my_login_redirect', 10, 3 );

function.php

<?php
if ( (isset($_GET['action']) && $_GET['action'] != 'logout') || (isset($_POST['login_location']) && !empty($_POST['login_location'])) ) {
	add_filter('login_redirect', 'my_login_redirect', 10, 3);
	function my_login_redirect() {
		$location = $_SERVER['HTTP_REFERER'];
		wp_safe_redirect($location);
		exit();
	}
}

does it support redirect user to previous page? In multsites? How use these code?
