WordPress的自定义文章类型重写页面和类别塞

Question

我已经建立了一个自定义后类型

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' 
    ) 
); 

我有一个城市名称的页面设置，我需要保持对于不同原因的页面，但我想要将该城市的社区作为自定义帖子类型进行存储。我为每个要添加社区的城市设置类别，但我希望他们将城市名称页面作为父级。

这样

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

我想城市名是一个网页，社区是一个存档页面和团体名是一个单一页面。

到目前为止，我发现的每个解决方案都会生成404个错误或与父页面发生冲突。

任何帮助表示赞赏。谢谢！

Answer 1

这应该为你做，但首先有两件事你应该知道。

1.）我不会推荐这个URL结构，因为它要求每个条目至少有一个类别。它将始终抓住阵列中的第一个。你需要写一个小插件让你的作者知道。这可能做的伎俩：

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

2），然后才能查看信息时，您需要访问设置>后，您的固定链接添加代码，以便它会迫使重写齐平。
