Codeigniter 如何在codeiginter中上传多张照片？

我正在尝试上传多张照片！我的代码正在运行，但它只上载了一张照片，而不是所有选定的照片

我的代码出了什么问题

if(count($_FILES["userfile"]["name"]) == 0) {
    $this->session->set_flashdata('success', '?? ????? ?????? ?????');
    redirect('accidents/index');
}
else {
    // configurations from upload library
    $config['upload_path'] = './uploads/images';
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $config['max_size'] = '2048000'; // max size in KB
    $config['max_width'] = '20000'; //max resolution width
    $config['max_height'] = '20000';  //max resolution height
    // load CI libarary called upload
    $this->load->library('upload', $config);
    for($count = 0; $count < count($_FILES["userfile"]["name"]); $count++) {
       // body of if clause will be executed when image uploading is failed
       if(!$this->upload->do_upload()) {
           $errors = array('error' => $this->upload->display_errors());
           // This image is uploaded by deafult if the selected image in not uploaded
           $image = 'no_image.png';    
       }
       // body of else clause will be executed when image uploading is succeeded
       else {
           $data = array('upload_data' => $this->upload->data());
           $image = $_FILES['userfile']['name'];  //name must be userfile 
       }
       $this->accidents_model->addphoto($image,$last_id);
   }
}

我在for循环的代码中发现了问题，它是在上传一个文件之后重定向到索引页的（这是错误的），如果重定向行必须在for循环的外部：）

这里是经过一些修改后的完整工作代码，可以为每个用户id创建文件夹（我从stack usere这里获取代码：）非常感谢）

在上传页面我使用

 public function upload() { 
$acc = $last_id;
        $file_path = ".uploads/images/" . $acc . '/';

        if (isset($_FILES['multipleUpload'])) {

            if (!is_dir('uploads/images/' . $acc)) {
                mkdir('.uploads/images/' . $acc, 0777, TRUE);
            }

            $files = $_FILES;
            $cpt = count($_FILES ['multipleUpload'] ['name']);
            $this->load->library('upload');
            for ($i = 0; $i < $cpt; $i ++) {

                $name = $files ['multipleUpload'] ['name'] [$i];
                $_FILES ['multipleUpload'] ['name'] = $name;
                $_FILES ['multipleUpload'] ['type'] = $files ['multipleUpload'] ['type'] [$i];
                $_FILES ['multipleUpload'] ['tmp_name'] = $files ['multipleUpload'] ['tmp_name'] [$i];
                $_FILES ['multipleUpload'] ['error'] = $files ['multipleUpload'] ['error'] [$i];
                $_FILES ['multipleUpload'] ['size'] = $files ['multipleUpload'] ['size'] [$i];

                $this->upload->initialize($this->set_upload_options($file_path));

                if(!($this->upload->do_upload('multipleUpload')) || $files ['multipleUpload'] ['error'] [$i] !=0)
                {
                    print_r($this->upload->display_errors());
                }
                else
                {

                    $this->accidents_model->addphoto($name,$acc);



                }
