如何将上传文件的名称保存在变量中（我是 CI 新手）？

我正在使用此代码进行测试：

我非常感谢您对这些人的帮助。

这是我正在使用的代码（由于stackoverflow的限制，我一遍又一遍地输入）：

<?php

class Gallery_model extends CI_Model {

    var $gallery_path;
    var $videos_path;
    var $thumbnail;
    var $video_name;

    function Gallery_model() {

        parent::__construct();

        $this->gallery_path = realpath(APPPATH . '../images');
        $this->videos_path = realpath(APPPATH . '../videos');
        $this->videos_path_tnumb = realpath(APPPATH . '../videos/thumb');

        $this->thumbnail = 'C://xampp//htdocs//upload//videos//thumb';
        $this->video_name = 'C://xampp//htdocs//upload//videos//79825_00_01_SC03_intro.mov';
    }

    function do_upload() {

        $config = array(
//            'allowed_types' => 'jpg|jpeg|png|gif',
//            'upload_path' => $this->gallery_path,
//            'max_size' => 10000

            'allowed_types' => 'avi|mp4|flw|mov',
            'upload_path' => $this->videos_path
        );

        $this->load->library('upload', $config);
        $field_name = "some_field_name";
        if ($this->upload->do_upload()) {
            $this->getThumbImage($_POST['userfile']);
        }
    }

    function getVideoInformation($videoPath) {
        $movie = new ffmpeg_movie($videoPath, false);

            $frameObject->resize(120, 90, 0, 0, 0, 0);
            imagejpeg($frameObject->toGDImage(), $tmbPath);
        } else {
            $imageName = "";
        }


        return $imageName;
    }

$upload_data = $this->upload->data(); //Returns array of containing all of the data related to the file you uploaded.
$file_name = $upload_data['file_name'];

从这里阅读更多关于v2.x和这里的 v3.x 的信息。
