我已经创建了一个自定义的帖子类型（公文包），并且正在使用内置的类别分类法。当我查看类别存档页面时，只有常规帖子显示在类别下，我的自定义帖子根本不存在。选择类别的选项在编辑帖子页面（和快速编辑）中，它们只是没有显示在前端。

我已尝试通过在“设置”下保存来刷新永久链接>；Permalinks，我也尝试过包括flush_rewrite_rules(); 在我的功能中。php。什么都没用？

这是我的自定义帖子类型代码（注意：我的自定义帖子可以很好地使用重写规则，只是类别）：

/**
 * Registers the \'apc_portfolio\' custom post type.
 *
 * @example register_post_type( $taxonomy, $args );
 * @see https://codex.wordpress.org/register_post_type#Parameters
 * @todo change public, to false
 */
