Codeigniter Pagination 3.0.4 排序目录和文件

Question

我有一个带有 codeIgniter 3.0.4 分页库的工作文件管理器。

我试图确保它在分页中首先显示目录，然后显示文件。

目前，codeigniter 分页按名称对目录和文件进行排序。

有关 codeigniter 分页的问题，如何确保它以所有方式首先显示目录。然后整理文件。

解决了我从其他地方找到了一些代码，使其对我有用。我现在也使用了 array_reverse();到目前为止一切正常。

<?php

        $this->load->library('pagination');
        $this->load->helper('custom');

    }

    public function index() {
        $data['title'] = 'File Manager';

        if ($this->uri->segment(3)) {

            $this_input_get_directory = $this->uri->segment(2) . '/' . $this->uri->segment(3);

        } else {

            $this_input_get_directory = $this->uri->segment(2) . '/' . $this->uri->segment(3);

        }

        } else {
