我创建了一个名为mfg_ppn 还有一种自定义分类法mfg_pp, 它们被引用为$this->cpt_promotion_news和$this->cpt_promotion如果你想知道的话。

管理中的一切看起来都很好，我可以轻松地将分类法分配给自定义帖子。但是当我使用http://example.com/promotion/company 我没有得到任何职位，即使有12个职位绑定到该特定术语。

下面是我用于注册帖子类型的PHP代码：

// Register campaign news:
register_post_type($this->cpt_promotion_news, array(
    \'labels\' => array(
        \'name\' => __(\'Campaign Posts\', $this->plugin_locale),
        \'singular_name\' => __(\'Promotion Campaign\', $this->plugin_locale),
        \'menu_name\' => __(\'Promotion\', $this->plugin_locale),
        \'all_items\' => __(\'All Campaign Posts\', $this->plugin_locale),
        \'add_new\' => __(\'Add New Post\', $this->plugin_locale),
        \'add_new_item\' => __(\'Add New Campaign Post\', $this->plugin_locale),
        \'edit_item\' => __(\'Edit Post\', $this->plugin_locale),
        \'new_item\' => __(\'New Post\', $this->plugin_locale),
        \'view_item\' => __(\'View Post\', $this->plugin_locale),
        \'search_items\' => __(\'Search Posts\', $this->plugin_locale),
        \'not_found\' => __(\'No posts found\', $this->plugin_locale),
        \'not_found_in_trash\' => __(\'No posts found in trash\', $this->plugin_locale),
        \'parent_item_colon\' => __(\'Post parent:\', $this->plugin_locale)
    ),
    \'description\' => __(\'News for a partner promotion campaign.\', $this->plugin_locale),
    \'public\' => true,
    \'exclude_from_search\' => true,
    \'show_in_nav_menus\' => true,
    \'menu_position\' => 25,
    \'show_in_menu\' => true,
    \'map_meta_cap\' => true,
    \'capabilities\' => array( \'manage_options\' ),
    \'capability_type\' => \'post\',
    \'hierarchical\' => false,
    \'supports\' => array( \'title\', \'editor\', \'thumbnail\', \'comments\' ),
    \'taxonomies\' => array( $this->cpt_promotion ),
    \'has_archive\' => true,
    \'rewrite\' => array(
        \'slug\' => __(\'promotion-post\', $this->plugin_locale)
    )
));

下面是注册分类法的代码：

// Register promotion campaigns:
register_taxonomy($this->cpt_promotion, $this->cpt_promotion_news, array(
    \'labels\' => array(
        \'name\' => __(\'Promotion Campaigns\', $this->plugin_locale),
        \'singular_name\' => __(\'Promotion Campaign\', $this->plugin_locale),
        \'menu_name\' => __(\'All Campaigns\', $this->plugin_locale),
        \'all_items\' => __(\'All Campaigns\', $this->plugin_locale),
        \'edit_item\' => __(\'Edit Campaign\', $this->plugin_locale),
        \'view_item\' => __(\'View Campaign\', $this->plugin_locale),
        \'update_item\' => __(\'Update Campaign\', $this->plugin_locale),
        \'add_new_item\' => __(\'Add New Promotion Campaign\', $this->plugin_locale),
        \'new_item_name\' => __(\'New Campaign Name\', $this->plugin_locale),
        \'parent_item\' => __(\'Post parent:\', $this->plugin_locale),
        \'parent_item_colon\' => __(\'Post parent:\', $this->plugin_locale),
        \'search_items\' => __(\'Search Campaigns\', $this->plugin_locale),
        \'add_or_remove_items\' => __(\'Add or Remove Campaigns\', $this->plugin_locale)
    ),
    \'public\' => true,
    \'show_ui\' => true,
    \'show_in_nav_menus\' => false,
    \'show_tagcloud\' => false,
    \'show_admin_column\' => true,
    \'hierarchical\' => true,
    \'query_var\' => true,
    \'rewrite\' => array(
        \'slug\' => __(\'promotion\', $this->plugin_locale)
    )
));

我还创建了一个名为taxonomy-mfg_pp, 这是分类法的名称，但它从不输出任何帖子，即使有帖子。罪魁祸首似乎是执行的WP\\U查询只查找帖子、页面和附件，如下所示：

SELECT SQL_CALC_FOUND_ROWS  qADrathuFrU2_posts.ID FROM qADrathuFrU2_posts  INNER JOIN qADrathuFrU2_term_relationships ON (qADrathuFrU2_posts.ID = qADrathuFrU2_term_relationships.object_id) WHERE 1=1  AND ( qADrathuFrU2_term_relationships.term_taxonomy_id IN (1196) ) AND qADrathuFrU2_posts.post_type IN (\'post\', \'page\', \'attachment\') AND (qADrathuFrU2_posts.post_status = \'publish\' OR qADrathuFrU2_posts.post_author = 1 AND qADrathuFrU2_posts.post_status = \'private\') AND qADrathuFrU2_posts.post_password = \'\'  GROUP BY qADrathuFrU2_posts.ID ORDER BY qADrathuFrU2_posts.post_date DESC LIMIT 0, 10

我是不是做错了什么，我是不是走错了路？

请帮帮我，因为最后期限快到了，我似乎做不好！

提前谢谢你Jonathan
