Question

我正在使用文件上传创建一个简单的crud应用程序。但我在视图中显示缩略图时遇到问题（index.blade.php）。数据库中的所有图像都显示在每本书中，而不是在一本书中显示一个图像。这是我的控制器。

＆＃13;

   public function index()
   {

 
        $books=UploadedFile::all();
        $files=Upload::all();

        return view('books.index',compact('books','files'));
   }

＆＃13;

和我的index.blade.php

＆＃13;

    <table class="table table-striped table-bordered table-hover">
         <thead>
         <tr class="bg-info">
             <th>Id</th>
             <th>ISBN</th>
             <th>Title</th>
             <th>Author</th>
             <th>Publisher</th>
             <th>Thumbs</th>
             <th colspan="3">Actions</th>
         </tr>
         </thead>
         <tbody>
       
         @foreach ($books as $book )
             <tr>
                 <td>{{ $book->id }}</td>
                 <td>{{ $book->isbn }}</td>
                 <td>{{ $book->title }}</td>
                 <td>{{ $book->author }}</td>
                 <td>{{ $book->publisher }}</td>

                 <td>
                    @foreach ($files as $file )
                        <img src="{{asset('uploads/'.$file->filename)}}" height="40" width="50">
                    @endforeach
                    
                </td>
                 <td><a href="{{url('books',$book->id)}}" class="btn btn-primary">Details</a></td>
                 <td><a href="{{route('books.edit',$book->id)}}" class="btn btn-warning">Update</a></td>
                 <td>
                 {!! Form::open(['method' => 'DELETE', 'route'=>['books.destroy', $book->id]]) !!}
                 {!! Form::submit('Delete', ['class' => 'btn btn-danger']) !!}
                 {!! Form::close() !!}
                 </td>
             </tr>
         @endforeach

         </tbody>

    </table>

＆＃13;

我将表格与其他字段分开。这是结果 -
