只需在函数中添加以下代码。php。它将重定向回提交登录表单的用户。

add_action( \'wp_login_failed\', \'my_front_end_login_fail\' );  // hook failed login

function my_front_end_login_fail( $username ) {
   $referrer = $_SERVER[\'HTTP_REFERER\'];  // where did the post submission come from?
   // if there\'s a valid referrer, and it\'s not the default log-in screen
   if ( !empty($referrer) && !strstr($referrer,\'wp-login\') && !strstr($referrer,\'wp-admin\') ) {
      wp_redirect( $referrer . \'?login=failed\' );  // let\'s append some information (login=failed) to the URL for the theme to use
      exit;
   }
}
