是否有任何方法可以禁用WP核心更新，但需要发送通知电子邮件，告知可以安装WP更新？我知道关于WP更新的通知电子邮件是在WP更新以及如何禁用所有（核心更新和通知）之后发送的。

我正在尝试使用以下代码：

function core_update_notification(){
    global $wp_version;

   $core_update = wp_version_check();

   if ($core_update != NULL || $core_update !=FALSE){
      $to = "[email protected]";
      $subject = "WP update is available!";
      $message = "You have WP update ready to install";
      $headers = \'From: My Website <[email protected]>\' . "\\r\\n";

      wp_mail( $to, $subject, $message, $headers );
   }

}

   add_action( \'init\', \'core_update_notification\' );
   add_filter( \'auto_update_core\', \'__return_false\' );

UPDATE #1看起来wp\\u version\\u check（）执行版本检查，如果有新版本，则设置update\\u core transient。它不会返回任何有价值的东西，这就是上面的代码失败的原因。需要使用get_site_transient(\'update_core\') 更新后的代码如下所示

function core_update_notification(){
   global $wp_version;

   $installed_version = $wp_version;

   $uc_transient = get_site_transient(\'update_core\');
   if ( empty($uc_transient->updates) ) return;
   $updates = $uc_transient->updates;
   $current_version = $updates[0]->current;

   if (version_compare($installed_version, $current_version, "<")) {
      $to = "[email protected]";
      $subject = "WP update is available!";
      $message = "You have WP update ready to install";
      $headers = \'From: My Website <[email protected]>\' . "\\r\\n";

      wp_mail( $to, $subject, $message, $headers );
   }

}

   add_action( \'init\', \'core_update_notification\' );
   add_filter( \'auto_update_core\', \'__return_false\' );
