我有一个wordpress主题，我通过制作一个儿童主题来修改外观和感觉。

我使用的父主题使用redux框架。

我对使用过滤器和挂钩有点陌生，但我想在选项页面上添加/修改一个部分。

我找到了一个通过子主题添加节的函数，但我不知道如何使用它。

当我在子主题函数中包含代码时。php我收到一个错误，说它不能被重新定义。

这是选项中显示的示例。php文件。

有谁能帮我解释一下如何使用这个函数，或者给我一些关于如何使用它的简明解释。

谢谢

/*
 *
 * Custom function for filtering the sections array. Good for child themes to override or add to the sections.
 * Simply include this function in the child themes functions.php file.
 *
 * NOTE: the defined constansts for URLs, and directories will NOT be available at this point in a child theme,
 * so you must use get_template_directory_uri() if you want to use any of the built in icons
