从多个输入中获取数据

Question

有一个表单和多个输入。表单有一个用于添加视频的字段。我还可以动态添加一组字段。

Here is how looks like a form

当我将多个数据提交到一个表单时，除了视频之外的所有数据都会正确传输。

Dump and die

帮助以数组形式发送多个视频。这是我的控制器：

public function store(Request $request)
{         
    $path = array_map(function ($v) {return $v->store('images', 's3');}, $request->file('link_video'));
    $userId = Auth::id();
    $course = Course::where('user_id', $userId)->orderBy('created_at', 'desc')->first();

    foreach ($request->lesson_id as $key => $file) {
        $file = File::create([
            'course_id' => $course->id,
            'user_id' => $userId,
            'lesson_id' => $request->input('lesson_id')[$key],
            'lesson_name' => $request->input('lesson_name')[$key],
            'description' => $request->input('description')[$key],
            'link_video' => Storage::disk('s3')->url($path[$key]),
        ]);
    }
    File::create($file);
    return redirect()->route('teaching')->with('success', 'Курс успешно создан!');
}

这是我的表格

            element.classList.remove('example_student');


            students.appendChild(element);
        });

        document.addEventListener('click', function(el) {

            if (el.target && el.target.classList.contains('js-remove')) {

                var child = el.target.closest('.table');

                child.parentNode.removeChild(child);
            }
        });

    </script>

Here is dd($request->file());

请分享刀片文件的代码，以便我们了解问题所在。 并确保您已将 encyt 类型定义为 multipart/form... 在表单中

还有一个建议你不需要使用 Auth::id() ，你可以这样调用 create

 auth()->user()->files()->create($file)

并且在模型 User.php 添加公共函数

   public function files(){
       return $this->hasMany(File::class);
   }

在模型 File.php 中

  public function user(){
    return $this->belongsTo(User::class);
  }

这样，您无需在每次添加新数据时调用 Auth::id，它会自动将当前登录用户的 ID 添加到您的数据的数据库中。
