因此共享相同的永久链接路径（或rewrite slug/base 如中所示example.com/<rewrite slug>/<term slug> 和example.com/<rewrite slug>/<post slug>) 是可能的，下面是（更新的）代码，您可以共享the exact same rewrite slug 在分类法和帖子类型之间：

function wpse_358157_parse_request( $wp ) {
    $path      = \'about-us/video-center\'; // rewrite slug; no trailing slashes
    $taxonomy  = \'video-category\';        // taxonomy slug
    $post_type = \'video\';                 // post type slug

    if ( preg_match( \'#^\' . preg_quote( $path, \'#\' ) . \'/#\', $wp->request ) &&
        isset( $wp->query_vars[ $taxonomy ] ) ) {
        $slug = $wp->query_vars[ $taxonomy ];
        $slug = ltrim( substr( $slug, strrpos( $slug, \'/\' ) ), \'/\' );

        if ( ! term_exists( $slug, $taxonomy ) ) {
            $wp->query_vars[\'name\']       = $wp->query_vars[ $taxonomy ];
            $wp->query_vars[\'post_type\']  = $post_type;
            $wp->query_vars[ $post_type ] = $wp->query_vars[ $taxonomy ];
            unset( $wp->query_vars[ $taxonomy ] );
        }
    }
}
add_action( \'parse_request\', \'wpse_358157_parse_request\' );

简要说明：

通过slug检查一个术语是否存在（比检查一个post是否存在）要容易得多，因此在上面的代码中，我们检查当前请求是否满足一个术语请求（即分类查询变量-例如。video-category — 存在于请求中，并且请求路径与分类法和post类型的重写slug匹配，如果是，则术语doesn\'t exist, 然后我们假设这是一个post请求。

一、 我们让WordPress将该请求视为一个帖子请求，而不是一个术语。

其他注意事项请确保您的帖子和术语不存在相同的问题。因为帖子和术语共享相同的重写段，所以无法知道我们应该加载帖子还是术语。

在最初的回答中，我提到分类法/术语permalink不能是分层的（例如。example.com/<rewrite slug>/<parent term slug>/<child term slug>/), 但实际上，它可以是分层的！我只是没有时间彻底测试一下……）

register_taxonomy( \'video-category\', \'video\', [
        \'rewrite\'      => [
            \'slug\'         => \'about-us/video-center\',
            \'with_front\'   => false,
            \'hierarchical\' => true, // enable hierarchical term permalink
        ],
        \'hierarchical\' => true,
        ...
    ]
);

因此，请尝试先注册分类法，然后注册post类型。如果这不起作用，那么首先注册post类型。

function my_register_taxonomy() {
    register_taxonomy( \'video-category\', \'video\', [
            \'rewrite\'      => [
                \'slug\'         => \'about-us/video-center\',
                \'with_front\'   => false,

                \'singular_name\' => \'Video Category\',
            ],
