WordPress-使用子主题添加到Redux主题选项

我正在使用一个wordpress主题，它具有自己的框架，该框架基于我认为的redux框架。我正在使用子主题修改此主题。我想在后端添加到“主题选项”，并且在父主题的文件中找到了一个功能，该功能似乎正是我所需要的：

/*
 *
 * 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
 *
 */
function add_another_section($sections){
    //$sections = array();
    $sections[] = array(
        'title' => __('A Section added by hook', 'swift-framework-admin'),
        'desc' => __('<p class="description">This is a section created by adding a filter to the sections array. Can be used by child themes to add/remove sections from the options.</p>', 'swift-framework-admin'),
        // Redux ships with the glyphicons free icon pack, included in the options folder.
        // Feel free to use them, add your own icons, or leave this blank for the default.
        'icon' => trailingslashit(get_template_directory_uri()) . 'options/img/icons/glyphicons_062_attach.png',
        // Leave this as a blank section, no options just some intro text set above.
        'fields' => array()
    );

    return $sections;
}
//add_filter('redux-opts-sections-twenty_eleven', 'add_another_section');

我已将此功能添加到子主题的functions.php中，并且未对add_filter进行注释。但是，这似乎不起作用，并且未添加任何新部分。

我在其他地方遇到过此讨论，该讨论表明需要更改函数的名称（我在此处遇到了相同的错误）。我已经做到了，但仍然行不通。

这是我的孩子主题functions.php中的内容

function add_another_section_bl($sections){
    $sections = array();
    $sections[] = array(
        'title' => __('A Section added by hook', 'swift-framework-admin'),
        'desc' => __('<p class="description">This is a section created by adding a filter to the sections array. Can be used by child themes to add/remove sections from the options.</p>', 'swift-framework-admin'),
        // Redux ships with the glyphicons free icon pack, included in the options folder.
        // Feel free to use them, add your own icons, or leave this blank for the default.
        'icon' => trailingslashit(get_template_directory_uri()) . 'options/img/icons/glyphicons_062_attach.png',
        // Leave this as a blank section, no options just some intro text set above.
        'fields' => array()
    );

    return $sections;
}
add_filter('redux-opts-sections-twenty_eleven', 'add_another_section_bl');

我不确定过滤器名称“ redux-opts-sections-twenty_eleven”是否需要编辑，因为它提到了二十一个主题。我尝试使用不同的主题名称（而不是二十一十一），但没有效果。

任何帮助将不胜感激！附带说明一下，通过将整个framwork文件夹复制到我的子主题中并在子主题的functions.php中定义框架的路径，我已经能够完成向主题选项中添加新选项的工作。我只是觉得应该有一种更流畅，更整洁的方法来实现这一目标，我认为该功能听起来很完美。

非常感谢。
