一次上传两个文件

Question

我正在尝试使用 codeigniters 上传类一次上传两个文件（两个文件字段）。尽管提供了字段名称 codeigniter 在第二个字段上产生错误。

这是对 codeigniter、php 或 html 的限制，还是我只是错误地使用了该类？

$this->upload->do_upload('video_file')

$this->upload->do_upload('image_file')

在图像字段上产生这个：

The filetype you are attempting to upload is not allowed.

这是我的两个函数

function upload_image() {
    $thumb_size = 94;
    $config['upload_path'] = './assets/uploads/images/';
    $config['allowed_types'] = 'jpg|png|gif';
    $config['max_size'] = '2048';
    $config['file_name'] = 'video_' . rand(999999, 999999999);
    $this->load->library('upload', $config);

    if (!$this->upload->do_upload('image_file')) {
        $error = array('error' => $this->upload->display_errors());
        return $error;
    } else {

function upload_video() {


    $config['upload_path'] = './assets/uploads/videos/';
    $config['allowed_types'] = 'flv';
    $config['max_size'] = '0';
    $config['file_name'] = 'video_' . rand(999999, 999999999);
    $this->load->library('upload', $config);
    if (!$this->upload->do_upload('video_file')) {
        $error = array('error' => $this->upload->display_errors());
        return $error;
    } else {

每次上传新文件时，它都可以将类加载为$this->load->library('upload');，然后使用$this->upload->initialize($config);。
