Wordpress 自定义帖子类型重写页面和类别 slug

Question

我已经设置了自定义帖子类型

register_post_type( 'Communities',
    array(
        'labels' => array(
        'name' => __( 'Communities' ),
        'singular_name' => __( 'Community' ),
        'not_found' => __( 'No Communities Found' )
        ),
        'public' => true,
        'rewrite' => array( 'slug' => '/%category%/communities', 'with_front' => false),
        'has_archive' => true,
        'hierarchical'  => true,
        'taxonomies'  => array( 'category' ),
        'supports' => array( 'title', 'editor', 'thumbnail', 'excerpt', 'custom-fields' ),
        'menu_icon' => 'dashicons-admin-home'
    )
);

我有一个带有城市名称的页面设置，出于不同原因我需要将其保留为页面，但我希望将该城市中的社区存储为自定义帖子类型。我为要添加社区的每个城市设置了类别，但我希望他们将城市名称页面视为父级。

喜欢这个

www.sitename.com/cityname/communities/communityname/

我希望 cityname 是一个页面，communities 是一个存档页面，communityname 是一个页面。

到目前为止，我发现的每个解决方案都会产生 404 错误或与父页面发生冲突。

感谢任何帮助。谢谢！

Answer 1

这应该为你做，但首先有两件事你应该知道。

1.) 我不推荐这种 URL 结构，因为它要求每个条目至少有一个类别。它总是会抓取数组中的第一个。您需要编写一个小插件让您的作者知道。这可能会奏效：

https://srd.wordpress.org/plugins/require-post-category/

2.) 在您查看帖子之前，您需要在添加代码后访问“设置”>“永久链接”，以便强制重写刷新。
