Wordpress 自定义帖子类型 - 相同的帖子名称，不同的帖子类型

Question

我有 4 种自定义帖子类型:

服务常见问题价格之前和之后

我希望能够在这些帖子类型中使用相同的帖子名称，例如:

Services
Skin (example.com/Services/skin)
Cream (example.com/Services/cream)
Body (example.com/Services/body)

FAQs
Skin (example.com/FAQs/skin)
Cream (example.com/FAQs/cream)
Body (example.com/FAQs/body)

Prices
Skin (example.com/Prices/skin)
Cream (example.com/Prices/cream)
Body (example.com/Prices/body)

Before and After
Skin (example.com/before-and-after/skin)
Cream (example.com/before-and-after/cream)
Body (example.com/before-and-after/body)

我该怎么做？现在，如果我创建一个与当前帖子同名的新帖子，它会在帖子 slug 的末尾添加一个“-2”或“-3”:

不好:

example.com/services/body

example.com/faqs/body-2

example.com/prices/body-3

example.com/before-and-after/body-4

请大家帮忙!!!!!!

我写了一个函数，可以添加到您主题的functions.php 文件中，其中包含mboynes 在这张票中编写的补丁:http://core.trac.wordpress.org/ticket/18962#comment:14

function wp_cpt_unique_post_slug($slug, $post_ID, $post_status, $post_type, $post_parent, $original_slug) {
    if ( in_array( $post_status, array( 'draft', 'pending', 'auto-draft' ) ) )
        return $slug;

    global $wpdb, $wp_rewrite;

    // store slug made by original function
    $wp_slug = $slug;

    // reset slug to original slug
    $slug = $original_slug;

    $feeds = $wp_rewrite->feeds;
    if ( ! is_array( $feeds ) )
        $feeds = array();

    $hierarchical_post_types = get_post_types( array('hierarchical' => true) );
    if ( 'attachment' == $post_type ) {
        // Attachment slugs must be unique across all types.
        $check_sql = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND ID != %d LIMIT 1";
        $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $slug, $post_ID ) );

        if ( $post_name_check || in_array( $slug, $feeds ) || apply_filters( 'wp_unique_post_slug_is_bad_attachment_slug', false, $slug ) ) {
            $suffix = 2;
            do {
                $alt_post_name = substr ($slug, 0, (200 - ( strlen( $suffix ) + 1 )) ) . "-$suffix";

            return $slug;

        // namespace than posts so page slugs are allowed to overlap post slugs.
        $check_sql = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND post_type = %s AND ID != %d AND post_parent = %d LIMIT 1";

            $suffix = 2;
