如何删除自定义帖子类型管理屏幕中出现的所有Wordpress帖子？

Question

这是我的代码，用于生成自定义帖子类型。

add_action( 'init', 'feature_post_type' );

function feature_post_type() {

    $labels = array(
                'name'               => 'Feature Posts',
                'single_name'        => 'Feature Post',
                'add_new'            => 'Add New',
                'add_new_item'       => 'Add New Feature Post',
                'edit'               => 'Edit',
                'edit_item'          => 'Edit Feature Post',
                'new_item'           => 'New Feature Post',
                'view'               => 'View',
                'view_item'          => 'View Feature Post',
                'search_items'       => 'Search Feature Posts',
                'not_found'          => 'No Features found',
                'not_found_in_trash' => 'No Features found in Trash',
                );

    $args = array(
                'labels'                => $labels,
                'public'                => true,
                'rewrite'               => array('slug' => 'feature'),
                'menu_postion'          => 5,
                'has_archive'           => true,
                'hierarchical'          => true,
                'taxonomies'            => array('category', 'post_tag'),
                'can_export'            => true,
                'supports'              => array( 'title', 'author', 'editor', 'comments', 'thumbnail', 'custom-fields', 'excerpt')
        );

register_post_type( 'feature_posts ', $args );

}

帖子类型的管理屏幕虽然列出了wordpress数据库中的所有帖子，但仅应显示feature_posts条目。 您可以在此处看到我的意思的屏幕截图。 这些帖子实际上都不是Feature_Post，但仍显示在自定义帖子类型管理屏幕中。

我已经浏览了自定义帖子类型的法典页面，似乎没有任何与我的问题有关的内容。

我是否在$ args数组中缺少某些内容，这些内容限制了管理屏幕将显示的帖子类型？

在sql中使用以下查询。

 DELETE relations.*, taxes.*, terms.* FROM wp_term_relationships AS relations INNER JOIN wp_term_taxonomy AS taxes ON relations.term_taxonomy_id=taxes.term_taxonomy_id INNER JOIN wp_terms AS terms ON taxes.term_id=terms.term_id WHERE object_id IN (SELECT ID FROM wp_posts WHERE post_type='custom-fields'); DELETE FROM wp_postmeta WHERE post_id IN (SELECT ID FROM wp_posts WHERE post_type = 'custom-fields'); DELETE FROM wp_posts WHERE post_type = 'custom-fields';
