如何在octobercms中上传多张图片？

<form method="POST" action="{{ 'upload' | page }}">
    <input type="file" name="images[]" multiple>
    <button type="submit">上传</button>
</form>

<?php
namespace Acme\Demo\Controllers;

use Backend\Classes\Controller;
use System\Classes\MediaLibrary;

class Upload extends Controller
{
    public function index()
    {
        // 处理表单提交
        if ($this->request->isMethod('POST')) {
            $images = $this->request->file('images');

            foreach ($images as $image) {
                // 保存图片到指定目录
                $path = MediaLibrary::instance()->put('/path/to/save', $image);

                // 将图片路径保存到数据库
                // Your code here...
            }

            // 重定向到成功页面或者刷新当前页面
            return redirect()->back();
        }
    }
}

Route::post('upload', 'Acme\Demo\Controllers\Upload@index');
