Question

我试图在Laravel中编辑文件，但是当我编辑文件时，其名称根据db中的edit而改变，但是文件并没有替换文件文件夹中的前一个文件，而是使用了资源路由，注意，当我存储文件时，其名称存储在一个表中，其数据存储在另一表中，需要的是当我编辑文件时，其数据来自其他文件必须更改，该怎么办？

控制器：

  <?php

 namespace App\Http\Controllers;

 use App\File;
 use Illuminate\Http\Request;
 use Spatie\PdfToText\Pdf;
 use Illuminate\Support\Facades\File as FileFacade;
 use DB;

 class FileController extends Controller
 {

    public function index()
    {
         $data = File::latest()->paginate(5);
         return view('index', compact('data'))->with('i', (request()->input('page', 1) - 1) * 5);
     }

     public function create()
     {
         return view('create');
     }

     public function store(Request $request)
     {
         request()->validate([
        'filename' => 'required',
         ]);

      $cols = ['Battery', 'No_of_questions_attempted', 'SAS', 'NPR', 'ST', 'GR'];

      $files = $request->file('filename');
      foreach ($files as $file) {
          $file_id = File::create([
              'filename' => $file->getClientOriginalName(),
          ])->id;

        $text = Pdf::getText($file->getRealPath(), base_path('poppler-utils/bin/pdftotext.exe'));

        $page5 = strpos($text, 'Page 5 of 8');
        $start = strpos($text, 'Verbal', $page5);
        $end = strpos($text, "\r\n\r\nSAS (with 90% confidence bands)", $page5);

        $table = substr($text, $start, $end - $start);

        $data = array_map(function ($row) use ($cols, $file_id) {
            return array_merge(compact('file_id'), array_combine($cols, $row));
        }, collect(explode("\r\n\r\n", $table))->chunk(count($cols))->toArray());

        \DB::table('importpdfs')->insert($data);

        $file->move(public_path('files'), $file->getClientOriginalName());
      }

    return redirect('/file')->with('Success', 'File uploaded successfully');
  }

   public function show($id)
   {
       $data = File::findOrFail($id);
      //dd($data);
      return view('show', compact('data'));
   }

   public function edit($id)
   {
      $data = File::findOrFail($id);
      $files = \DB::table('files')->get();

      return view('edit', compact('data', 'files'));
   }

   public function update(Request $request, $id)
   {
       // Do the validation before you do anything else
       $request->validate([
          'filename' => 'required',
       ]);

       // Get the file from the request
       $file = $request->file('filename');

       $clientName = $file->getClientOriginalName();

       // Store the file in the `files` directory
       $path = $file->move(public_path('files'), $clientName);

       // Update the model
       File::whereId($id)->update(['filename' => $clientName]);

       // Redirect to some page
       return redirect('file')->with('success', 'Data is successfully updated');
   }


    public function destroy($id)
    {
       $file = File::find($id);
       $file->delete(public_path('files'));

      $file->delete();

      return redirect('file')->with('success', 'Data is successfully deleted');
    }
  }

刀片文件：

   <form method="post" action="{{ route('file.update', $data->id) }}" enctype="multipart/form-data">
        @csrf
        @method('PATCH')
        <div class="form-group">
          <label for="EditFile">Edit File</label>
          <input type="file" name="filename" class="form-control-file">
          <img src="{{ URL::to('/') }}/files/{{ $data->file }}" width="100"/>
          <img src="./images/pdf.png" class="img-circle elevation-2" alt="Pdf Image" width="50">
          <input type="hidden" name="hidden_file" value="{{ $data->file }}" />
        </div>
        <br>
        <input type="submit" name="edit" class="btn btn-primary input-lg" value="Edit" />
    </form>
