如何在CPT固定链接中添加自定义分类插件？

这是我迄今为止添加CPT的代码articles 和分类学articles-category.

代码正常，分类。页面显示正确（当我直接访问它们时）：

articles/

articles/categ-slug/

articles/categ-slug/post-slug/

自动生成永久链接时出现问题（例如：yoast breadcrumbs）

<span typeof="v:Breadcrumb">
<a href="example.com" rel="v:url" property="v:title">Example</a> /
<span rel="v:child" typeof="v:Breadcrumb"><a href="example.com/articles/%articles-category%/" rel="v:url" property="v:title">Articles</a> /
<span rel="v:child" typeof="v:Breadcrumb"><a href="example.com/articles/categ-slug/" rel="v:url" property="v:title">Category name</a> /
<span class="breadcrumb_last">Post Name</span></span></span></span>

注意事项example.com/articles/%articles-category%/ 应该在哪里example.com/articles/

代码中有什么错误，如何使其工作？

无法在模板函数.php中使用IS_HOME

我试图在标题中加载一个滑块，但只在主页上加载。如果有帮助的话，我正在使用Ultralight模板。我正在尝试（在template functions.php中）执行以下操作：<?php if ( is_page( \'home\' ) ) : ?> dynamic_sidebar( \'Homepage Widget\' ); <?php endif; ?> 但这行不通。现在，通过快速的google，我似乎需要将请
