WordPress的自定義帖子類型重寫頁面和類別標簽

Question

我已經設置了自定義帖子類型

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'
    )
);

我有一個帶有城市名稱的頁面設置，出於各種原因，我需要將其保留為頁面，但我希望將該城市中的社區存儲為自定義帖子類型。 我為要添加社區的每個城市設置了類別，但是我希望他們將城市名稱頁面視為父級。

像這樣

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

我希望cityname是一個頁面，community是一個存檔頁面，而communityname是一個頁面。

到目前為止，我發現的每個解決方案都會產生404錯誤或與父頁面沖突。

任何幫助表示贊賞。 謝謝！

Answer 1

這應該為您做，但是首先您應該知道兩件事。

1.）我不建議使用此URL結構，因為它要求每個條目至少具有一個類別。 它將始終搶占陣列中的第一個。 您需要編寫一個小插件，以告知您的作者。 這可能會達到目的：

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

2.）在查看帖子之前，添加代碼后，您需要訪問設置>永久鏈接，以強制進行重寫刷新。
