所以我一直在WordPress网站上工作，我需要一个文档自定义帖子，该帖子应该注册为“文档”。我在插件Meta框中生成了自定义帖子的代码，并将代码放在了我的函数中。php文件（尽管在测试时，我禁用了Meta-Box，以查看它是否有干扰，同时保留它在functions.php中生成的php）。我有一个模板，一个文档。php文件，在我的主题的根目录中（如果有区别的话，它是一个子主题）。但WordPress一直默认为single。php，即使在刷新permalinks之后。

这是为添加自定义帖子而生成的代码元框：

function register_document() {

    $args = array (
        \'label\' => esc_html__( \'Documents\', \'mb86\' ),
        \'labels\' => array(
            \'menu_name\' => esc_html__( \'Documents\', \'mb86\' ),
            \'name_admin_bar\' => esc_html__( \'Document\', \'mb86\' ),
            \'add_new\' => esc_html__( \'Add new\', \'mb86\' ),
            \'add_new_item\' => esc_html__( \'Add new Document\', \'mb86\' ),
            \'new_item\' => esc_html__( \'New Document\', \'mb86\' ),
            \'edit_item\' => esc_html__( \'Edit Document\', \'mb86\' ),
            \'view_item\' => esc_html__( \'View Document\', \'mb86\' ),
            \'update_item\' => esc_html__( \'Update Document\', \'mb86\' ),
            \'all_items\' => esc_html__( \'All Documents\', \'mb86\' ),
            \'search_items\' => esc_html__( \'Search Documents\', \'mb86\' ),
            \'parent_item_colon\' => esc_html__( \'Parent Document\', \'mb86\' ),
            \'not_found\' => esc_html__( \'No Documents found\', \'mb86\' ),
            \'not_found_in_trash\' => esc_html__( \'No Documents found in Trash\', \'mb86\' ),
            \'name\' => esc_html__( \'Documents\', \'mb86\' ),
            \'singular_name\' => esc_html__( \'Document\', \'mb86\' ),
        ),
        \'public\' => true,
        \'description\' => \'Handbooks, manuals, and other documents.\',
        \'exclude_from_search\' => false,
        \'publicly_queryable\' => true,
        \'show_ui\' => true,
        \'show_in_nav_menus\' => true,
        \'show_in_admin_bar\' => true,
        \'show_in_rest\' => true,
        \'menu_icon\' => \'dashicons-book-alt\',
        \'capability_type\' => \'post\',
        \'hierarchical\' => false,
        \'has_archive\' => true,
        \'query_var\' => true,
        \'can_export\' => true,
        \'rewrite_no_front\' => false,
        \'supports\' => array(
            \'title\',
            \'thumbnail\',
        ),
        \'rewrite\' => true,
    );

    register_post_type( \'document\', $args );
}
add_action( \'init\', \'register_document\' );

由于解决此问题的大多数主题都集中在更新permalinks上（我已经多次尝试），因此我不确定如何解决此问题。有什么想法吗？
