Wordpress自定义邮政类型-相同的邮政名称，不同的邮政类型

Question

我有4种自定义邮政类型：

服务常见问题前后的价格

我希望能够在每种帖子类型中都有相同的帖子名称，例如：

服务 皮肤(example.com/Services/皮肤) “奶油”(example.com/Services/ Cream ) Body (example.com/Services/body) 常见问题 皮肤(example.com/常见问题/皮肤) 奶油(example.com/常见问题/奶油) Body (example.com/FAQ/body) 价格 皮肤(example.com/Price/皮肤) 奶油(example.com/Price/ Cream ) Body (example.com/Price/body) 前后 皮肤(example.com/前后/皮肤) 霜(example.com/前后/霜) Body (example.com/前后/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，它会在帖子的末尾添加一个"-2“或"-3”：

坏：

example.com/services/body Example.com/常见问题/正文-2 example.com/prices/body-3 Example.com/前后/body-4

救命啊！

我编写了一个函数，该函数可以添加到主题的functions.php文件中，其中包括mboynes在此票证中编写的修补程序：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";
                $post_name_check = $wpdb->get_var( $wpdb->prepare($check_sql, $alt_post_name, $post_ID ) );
                $suffix++;
            } while ( $post_name_check );
            $slug = $alt_post_name;
        }
    } elseif ( in_array( $post_type, $hierarchical_post_types ) ) {
        if ( 'nav_menu_item' == $post_type )
            return $slug;
        // 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 = %s AND ID != %d AND post_parent = %d LIMIT 1";
        $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $slug, $post_type, $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_type, $post_ID, $post_parent ) );
                $suffix++;
            } while ( $post_name_check );
            $slug = $alt_post_name;
        }
    } else {
        // Post slugs must be unique across all posts.
        $check_sql = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND post_type = %s AND ID != %d LIMIT 1";
        $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $slug, $post_type, $post_ID ) );

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

            } while ( $post_name_check );
            $slug = $alt_post_name;
        }
    }

    return $slug;
}
add_filter('wp_unique_post_slug', 'wp_cpt_unique_post_slug', 10, 6);

我认为这是一个尚未被wordpress程序员团队解决的bug。下面是一些关于它的其他解释：允许不同内容的重复鼻涕虫

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_include/post.php)中的wp_unique_post_slug检查插入的permalink是否唯一。

不幸的是，我被迫黑了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..。如果任何人知道任何其他的解决方案，或更重要的是，如果任何人知道任何不可预测的后果，将影响我找到的解决方案，请告诉我，我会非常感激！

只有一个解决办法。您的帖子需要一个唯一的标识符(slug)，不能在url中使用相同的名称。除非它们是等级的。您可以使用自定义的post类型来实现这一点。用途：

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

然后，您将能够具有不同的自定义post类型的相同名称。
