Question

我试图创建一个数据库来存储图像。它存储该图像的URL，并且插入工作正常。但是，它以数组格式另存为["light.jpg"]。现在，我想显示存储在数据库中的图像，但它只显示图像图标，而不显示图像。图像存储在公用文件夹内的图像文件夹中。

下面我附上我的代码：

表单控制器：

public function store(Request $request)
{

    $this->validate($request, [
            'filename' => 'required',
            'filename.*' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048'
    ]);

    if($request->hasfile('filename'))
    {
        foreach($request->file('filename') as $image)
        {
            $name=$image->getClientOriginalName();
            $image->move(public_path().'/images/', $name);  
            $data[] = $name;  
        }
     }

     $form= new Form();
     $form->filename=json_encode($data);
     $form->save();
     return back()->with('success', 'Your images has been successfully');
 }
 public function show()
 {
    $users = DB::select('select * from forms');
    return view('display',['users'=>$users]);
 }

插入页面

<form method="post" action="{{url('form')}}" enctype="multipart/form-data">
  {{csrf_field()}}

        <div class="input-group control-group increment" >
          <input type="file" name="filename[]" class="form-control">
          <div class="input-group-btn"> 
            <button class="btn btn-success" type="button"><i class="glyphicon glyphicon-plus"></i>Add</button>
          </div>
        </div>
        <div class="clone hide">
          <div class="control-group input-group" style="margin-top:10px">
            <input type="file" name="filename[]" class="form-control">
            <div class="input-group-btn"> 
              <button class="btn btn-danger" type="button"><i class="glyphicon glyphicon-remove"></i> Remove</button>
            </div>
          </div>
        </div>

        <button type="submit" class="btn btn-primary" style="margin-top:10px">Submit</button>

  </form>        
  </div>


<script type="text/javascript">      
    $(document).ready(function() {    
      $(".btn-success").click(function(){ 
          var html = $(".clone").html();
          $(".increment").after(html);
      });

      $("body").on("click",".btn-danger",function(){ 
          $(this).parents(".control-group").remove();
      });    
    });
</script>

显示页面：

 @foreach ($users as $user)
     <img src="{{ url('images/$user->filename') }}"/>
 @endforeach

Answer 1

@foreach ($users as $user)
 @php $images = json_decode($user->filename,true); @endphp
   @if(is_array($images) && !empty($images))
   @foreach ($images as $image)
     <img src="{{ url('images/'.$image) }}"/>
   @endforeach
   @endif
@endforeach

如果您将图像另存为json格式，这就是这种方式。所以我已经把情况也检查了

Answer 2

在刀片模板中，您要在img src中插入json格式，但应该插入单个文件名。您会看到您的文件名存储为json，因此您需要解码json格式并为每个文件名运行foreach，如下所示。

@foreach ($users as $user)
   @php $filenames = json_decode($user->filename); @endphp
   //filenames are decoded now and you can use the foreach loop just like below
   @foreach ($filenames as $singlefilename)    
     <img src="{{ url('images/' . $singlefilename) }}"/>
   @endforeach

@endforeach
