我有 4 种自定义帖子类型：

服务 常见问题 之前和之后的价格

我希望能够在这些帖子类型中使用相同的帖子名称，例如：

服务
皮肤 (example.com/Services/skin)
霜 (example.com/Services/cream)
身体 (example.com/Services/body)

皮肤
(example.com/FAQs/skin)
面霜 (example.com/FAQs/cream)
身体 (example.com/FAQs/body)

价格
皮肤 (example.com/Prices/skin)
奶油 (example.com/Prices/cream)
身体 (example.com/Prices/body)


皮肤前后(example.com/before-and-after/skin)
面霜 (example.com/before-and-after/cream)
身体 (example.com/before-and-after/body)

我怎样才能做到这一点？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”：

坏的：

example.com/services/body

example.com/faqs/body-2

example.com/prices/body-3

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

有人请帮忙！！！！

我写了一个函数，可以添加到你的主题的functions.php文件中，其中包括这张票中mboynes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 {

我认为这是 wordpress 程序员团队尚未解决的错误。这里有一些关于它的其他解释：允许不同内容的重复 slugs

我在这个函数中发现了一个不正确的编写代码：位于核心文件 (wp_includes/post.php) 中的 wp_unique_post_slug 检查插入的永久链接是否唯一。

不幸的是，我被迫破解核心代码来修复这个错误。我已经替换了从第 2859 行开始的代码部分：

} elseif ( in_array( $post_type, $hierarchical_post_types ) ) {
    // Page slugs must be unique within their own trees. Pages are in a separate
    // 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 IN ( '" . implode( "', '", esc_sql( $hierarchical_post_types ) ) . "' ) AND ID != %d AND post_parent = %d LIMIT 1";
    $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $slug, $post_ID, $post_parent ) );

    if ( $post_name_check || in_array( $slug, $feeds ) || preg_match( "@^($wp_rewrite->pagination_base)?\d+$@", $slug )  || apply_filters( 'wp_unique_post_slug_is_bad_hierarchical_slug', false, $slug, $post_type, $post_parent ) ) {
        $suffix = 2;
        do {
            $alt_post_name = substr( $slug, 0, 200 - ( strlen( $suffix ) + 1 ) ) . "-$suffix";
            $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $alt_post_name, $post_ID, $post_parent ) );
            $suffix++;
        } while ( $post_name_check );
        $slug = $alt_post_name;
    }
}

用我写的这段代码：

} elseif ( in_array( $post_type, $hierarchical_post_types ) ) {

    // HACK
    foreach($hierarchical_post_types as $pt){

            // Page slugs must be unique within their own trees. Pages are in a separate
            // namespace than posts so page slugs are allowed to overlap post slugs.                                

            // HACK
            $check_sql_andrea = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND post_type = %s AND ID != %d AND post_parent = %d LIMIT 1";
            // HACK
            $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql_andrea, $slug, $pt, $post_ID, $post_parent ) );

            if ( $post_name_check || in_array( $slug, $feeds ) || preg_match( "@^($wp_rewrite->pagination_base)?\d+$@", $slug )  || apply_filters( 'wp_unique_post_slug_is_bad_hierarchical_slug', false, $slug, $post_type, $post_parent ) ) {
                $suffix = 2;
                do {
                    $alt_post_name = substr( $slug, 0, 200 - ( strlen( $suffix ) + 1 ) ) . "-$suffix";
                    // HACK
                    $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql_andrea, $alt_post_name, $pt, $post_ID, $post_parent ) );
                    $suffix++;
                } while ( $post_name_check );
                $slug = $alt_post_name; 
                break;                          
            }
    }// END HACK

}

请...如果有人知道此案的任何其他解决方案，或者更重要的是，如果有人知道任何会影响我找到的解决方案的不可预测的后果，请告诉我，我将非常感激！

我已经搜索了对这个问题的其他参考（它也发生在不同父类别的子类别中），甚至标记为未来版本的增强，在该票证中，我在 wp-includes/ post.xml 中找到了对函数wp_unique_post_slug的引用。 php。也许你应该看看它并找出解决当前 WP 不当行为的方法。

一个肮脏的解决方案可能是重新检查完整的 slug 输出，如果没有重复，修剪添加的数字后缀，但我是阅读WP 源代码的新手，以提供更多建议。

只有一种解决方案。您的帖子需要一个唯一标识符（slug），并且不能在 url 中使用相同的名称。除非它们是分层的。您可以使用自定义帖子类型来做到这一点。利用 ：

        register_post_type(
            'customposttype', 
            array(
                'label' => '...',
                'description' => '...',
                'public' => true,
                'exclude_from_search' => false,
                'hierarchical' => true, ...

然后，您将能够拥有具有不同自定义帖子类型的相同名称

请注意不要在您发送的两个问题上发布不同的代码。

一种解决方案可能是将您的rewrite规则更改为with_frontfalse。例如，如果您设置

'rewrite => array( 
    'slug' => 'service',
    'with_front' => 'false'
)

您应该能够在每个类别中使用相同的类别/分类法而不会发生冲突。

根据您所做的事情，您可能还必须为每个自定义帖子类型定义一个独特的分类法。
