Laravel 媒体多上传

Question

我正在尝试上传多节课。但是有些东西不起作用。我认为 $data->lesson 有问题无法上课，或者 create 的问题真的不知道我是新手 :) 这是我的控制器

public function storeLesson(Lesson $lesson)
    {
        $data = request()->validate([
            'lesson.lesson' => 'required',
            'lesson_folder_id.lesson_folder_id' => '',
        ], [
            'lesson.lesson.required' => 'error message',
        ]);
        if (request()->hasFile('lesson')) {
            $path = request()->file('lesson')->store('lessons', ['disk' =>      'my_files']);
            $data->lesson = $path;
        }


        $create = $lesson->create($data['lesson'],['lesson_folder_id']);

        return redirect('/courses')->with('success', 'success message.');
    }

文件系统.php

 'disks' => [

        'local' => [
            'driver' => 'local',
            'root' => storage_path('app'),
        ],

        'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public'),
            'url' => env('APP_URL') . '/storage',
            'visibility' => 'public',
        ],

        's3' => [
            'driver' => 's3',
            'key' => env('AWS_ACCESS_KEY_ID'),
            'secret' => env('AWS_SECRET_ACCESS_KEY'),
            'region' => env('AWS_DEFAULT_REGION'),
            'bucket' => env('AWS_BUCKET'),
            'url' => env('AWS_URL'),
            'endpoint' => env('AWS_ENDPOINT'),
            'use_path_style_endpoint' => env('AWS_USE_PATH_STYLE_ENDPOINT', false),
        ],

        'my_files' => [
            'driver' => 'local',
            'root'   => public_path() . '/'
        ]
    ],

还有我的刀

<form method="POST" action="{{ route('storeLesson') }}" enctype="multipart/form-data">
            <div class="mb-3">
                @foreach($c->lessonFolders as $f)
                {{ $f->name }}
                <input hidden name="lesson_folder_id[lesson_folder_id]" type="text" value="{{ $f->id }}">
                <label class="form-label" for="customFile"></label>
                <input name="lesson[lesson]" type="file" class="form-control" id="customFile">
                @foreach($f->lessons as $l)
                @if($l->lesson)
                TRUE
                @endif
                @endforeach
                @endforeach
            </div>
            <button class="btn btn-danger" type="submit">upload</button>
        </form>

那么我做错了什么？是控制器故障还是我的刀片故障？

Answer 1

如果你将lesson[]命名为输入标签，$request->lesson将给出一个数组而不是一个文件，所以你不能使用request()->hasFile('lesson')

你应该使用name="lesson"进行单次上传，如果你想多次上传你应该使用lesson[]然后在控制器中

    if (is_array(request()->lesson)) {
        foreach (request()->lesson as $lesson) {
            $path = $lesson->store('lessons', ['disk' => 'my_files']);
            $data->lesson = $path;
        }
    }
