我正在使用一个带有内置保留的父主题，这是由不同开发人员对保留插件的修改。它并没有完全满足我们的需要，所以我们购买了独立的高级插件。除了父主题在其中一个主题文件中有以下语句外，其他都可以正常工作shortcodes.php:

if (class_exists(\'rtbInit\')) {    
include_once \'bookingtable/bookingtable.php\';
}

该文件破坏了premium插件的日期和时间函数，因此，我创建了一个shortcodes.php 文件，并注释了include行，但这不起作用。只有在父主题中对该行进行注释时，它才起作用。

有没有办法在子主题中添加函数或其他内容NOT 是否包含该文件？

非常感谢。

以下是的代码bookingtable.php
