多个自定义帖子类型,相同的URL结构

标签: wordpress custom-post-type permalinks

出于某种原因,我无法使用相同的网址结构创建多个CPT,例如我无法使用以下内容:

/cpt1/overview
/cpt1/events

/cpt2/overview
/cpt2/events

最终发生的事情如下:

/cpt1/overview
/cpt1/events

/cpt2/overview-2
/cpt2/events-2

我在干净安装wp时尝试了以下操作,以确保没有任何东西搞乱它:

add_action( 'init', function() 
{
    register_post_type( 'cpt1', array(
        'labels' => array(
            'name'                  => __('CPT1'),
            'singular_name'         => _x('Page', 'singular name'),
            'add_new'               => _x('Add New', 'page'),
            'all_items'             => __('All Pages'),
            'add_new_item'          => __('Add New Page'),
            'edit_item'             => __('Edit Page'),
            'new_item'              => __('New Page'),
            'view_item'             => __('View Page'),
            'search_items'          => _x('Search Pages', 'plural'),
            'not_found'             => _x('No pages found', 'plural'),
            'not_found_in_trash'    => _x('No pages found in Trash', 'plural'), 
            'parent_item_colon'     => '',
        ),
        'public' => true,
        'has_archive' => true,
        'rewrite' => array( 'slug' => 'cpt1', 'with_front' => false ),
        'show_in_nav_menus' => false,
        'hierarchical' => true,
        'supports' => array( 'author', 'title', 'editor', 'custom-fields', 'page-attributes', 'revisions' ),
    ));
} );

add_action( 'init', function() 
{
    register_post_type( 'cpt2', array(
        'labels' => array(
            'name'                  => __('CPT2'),
            'singular_name'         => _x('Page', 'singular name'),
            'add_new'               => _x('Add New', 'page'),
            'all_items'             => __('All Pages'),
            'add_new_item'          => __('Add New Page'),
            'edit_item'             => __('Edit Page'),
            'new_item'              => __('New Page'),
            'view_item'             => __('View Page'),
            'search_items'          => _x('Search Pages', 'plural'),
            'not_found'             => _x('No pages found', 'plural'),
            'not_found_in_trash'    => _x('No pages found in Trash', 'plural'), 
            'parent_item_colon'     => '',
        ),
        'public' => true,
        'has_archive' => true,
        'rewrite' => array( 'slug' => 'cpt2', 'with_front' => false ),
        'show_in_nav_menus' => false,
        'hierarchical' => true,
        'supports' => array( 'author', 'title', 'editor', 'custom-fields', 'page-attributes', 'revisions' ),
    ));
} );

我可能会追求什么?怎么样?

正如我正在进一步研究这个......似乎wordpress会重定向以下内容(不管我做任何额外的配置)......

/cpt2/overview/
/cpt2/events/

/cpt2/overview-2/
/cpt2/events-2/

我找到了以下wp函数wp_unique_post_slug(带有一个可用的过滤器),它检查slugs页面/帖子如果找到重复(附加-2,-3等)返回一个唯一的slug ..如果你看看函数本身,它确实进行了post_type检查,但只有当post_type设置为非分层时...否则它会找到所有分层post_types并检查所有的唯一性(例如post,page,book,event ..作为示例)。

答案 0 :(得分:1)

这是我对上述问题的解决方案,我希望得到更多反馈和/或更好的解决方案...以下使用来自wp_unique_post_slug的代码,该代码仅在自定义帖子类型和内部检查slug唯一性层次结构。

注意:这是有效的,因为cpt1和cpt2使用自己的固定链接前缀...

add_filter( 'wp_unique_post_slug', function( $slug, $post_ID, $post_status, $post_type, $post_parent, $original_slug ) 
{
    if ( in_array( $post_type, array( 'cpt1', 'cpt2' ) ) )
    {
        // start with a base slug w/o any suffixes
        $slug = preg_replace( '/(-\d+)$/', '', $slug );

        global $wpdb, $wp_rewrite;

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

        $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;
        }
    }

    return $slug;
}, 10, 6 );
