Means After adding code in function.php file, when i hit some pages and groups pages then it not redirect to login page. Helped me where i am wrong in this code. Also i have created login page not using BP login or wp-login

function login_required() {
if (!is_user_logged_in() ) {

          $restricted = array(6,13,552,12,121,491,534,23,233,24,234,74,117,419); // all your restricted pages
          if ( in_array(get_the_ID(), $restricted ) ) {
            wp_redirect(home_url()); 
            exit();
        }
    }
}
