我试图找出，如何更改Feedzy Wordpress RSS小部件，用于显示RSS提要，以便显示RSS订阅按钮。
我尝试将我的按钮代码添加到PHP文件内部的HTML部分的不同部分，但没有任何成功。在这样做的时候，我正在检查网站上是否在网上提到了我的按钮代码，但没有。 你能否建议，如何解决这个问题？
这是Feedzy RSS PHP：
<?php
/**
* The file that defines the core plugin class
*
* A class definition that includes attributes and functions used across both the
* public-facing side of the site and the admin area.
*
* @link http://themeisle.com
* @since 3.0.0
*
* @package feedzy-rss-feeds
* @subpackage feedzy-rss-feeds/form
*/
$html_parts = Feedzy_Rss_Feeds_Ui_Lang::get_form_elements();

这是我的订阅按钮的HTML：

</form>
感谢您提出任何建议。
