问题：

当我上传文件时，我将错误视为标题。但如果我没有上传文件，验证就可以了。我还检查了$ request，但我仍然不知道是什么问题。

这是我的$ smreenshot请求 $request

这是我的代码

$rules = [
          'edu_title'  => 'max:255',
          'edu_author' => 'max:10',
          'categories' => 'max:100',
          'file_name'  => 'nullable|file',
          'updated_at' => 'date|before:tomorrow'
         ];

    $messages = [
                'required' => '此欄位必填',
                'max'      => '此欄位最大長度必須小於 :max',
                'date'     => '請選擇日期',
                'before'   => '選擇的日期錯誤'
                ];

    $validate = Validator::make($request->all(), $rules, $messages);

    if($validate->fails()) {
        return back()->witherrors($validate)->withInput();
    }

    $path = '';

    if($request->hasFile('file_name')) {

    $validate = Validator::make($request->file_name, ['file_name' => 'file']);

    if( Storage::disk('local')->exists($directories.'/'.$file_name) ) {
            return back()->with('file exists', '檔案已經存在或檔名重複')->withInput();
        }

        $path = $request->file('file_name')->storeAs(
                $directories, $file_name);             
    }

    OtherTeachingMaterial::find($id)->update([
                            'edu_title'  => $request->edu_title,
                            'edu_author' => $request->edu_author,
                            'file_path'  => $path,
                            'categories' => $request->categories,
                            'updated_at' => $request->updated_at
                        ]);

    return redirect()->route('others_teahcing_material.dashboard')->with('success', '更新成功');

您可以将文件static T[,] CreateRectangularArray<T>(T[][] arrays) { // TODO: Validation and special-casing for arrays.Count == 0 int minorLength = arrays[0].Length; T[,] ret = new T[arrays.Length, minorLength]; for (int i = 0; i < arrays.Length; i++) { var array = arrays[i]; if (array.Length != minorLength) { throw new ArgumentException ("All arrays must be the same length"); } for (int j = 0; j < minorLength; j++) { ret[i, j] = array[j]; } } return ret; } 添加到string[][] allEvars = new string[evars.Count][]; for (var i = 0; i < evars.Count; i++) { var evarsList = new List<string>(); evarsList.Add(evars[i].id.Value); evarsList.Add(evars[i].name.Value); if (evars[i].enabled != null) evarsList.Add(evars[i].enabled.Value.ToString()); else evarsList.Add(""); if (evars[i].description != null) evarsList.Add(evars[i].description.Value); else evarsList.Add(""); string[] evarsArray = evarsList.ToArray(); //var range = (Excel.Range)wsEvars.Range[wsEvars.Cells[i + 5, 2], wsEvars.Cells[i + 5, evarsArray.Length]]; //range.Value = evarsArray; allEvars[i] = evarsList.ToArray(); } var range = (Excel.Range)wsEvars.Range[wsEvars.Cells[5, 2], wsEvars.Cells[allEvars.Length, 3]]; string[,] newallEvars = CreateRectangularArray<string>(allEvars); //added row range.Value2 = newallEvars; // changed row数组中，然后删除第二个rule方法，以便{{1}数组将是：

$rules

Illuminate \ Validation \ Factory :: make（）必须是类型数组，给定
