WordPress的自定义帖子类型重写页面和类别标签

Question

I have set up a custom post type

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'
    )
);

I have a pages setup with a city name that I need to remain as a page for different reasons, but I want communities in that city to be stored as a custom post type. I have setup categories for each city that I am adding communities to but I would like them to treat the cityname page as the parent.

like this

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

I would like cityname to be a page, communities to be an archive page and the communityname to be a single page.

Every solution I have found thus far generates 404 errors or conflicts with the parent page.

Any help is appreciated. Thanks!

Answer 1

This should do it for you, but first there are 2 things you should know.

1.) I wouldn't recommend this URL structure as it mandates that every entry have at least ONE category. It will always grab the first in the array. You'll need to write a small plugin to let your authors know. This may do the trick:

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

2.) Before you can view a post, you'll need to visit Settings > permalinks after you add the code so it will force a rewrite flush.
