【问题描述】：

请帮我解决这个问题

我的控制器代码是

public function index()
 


    $callrecordings = DB::table('callrecordings')
        ->join('users', 'users.id', '=', 'callrecordings.user_id')
        ->leftJoin('disableapp', 'callrecordings.user_id', '=', 'disableapp.user_id')
        ->select('callrecordings.*', 'users.expiry_date')
        ->where('callrecordings.user_id', '=', Auth::id())
        ->where(function($q)
            $q->where('disableapp.status', '=', 1)
                ->orWhereNull('disableapp.status');
        )
        ->paginate(5);

        dd($callrecordings);

        if($callrecordings[0]->expiry_date <= Carbon::now()->toDateTimeString())

        $result = 'That email belongs to an existing referrer.';

        return view('frontend.views.package-expire', compact('result'));
      

      else
         return view('frontend.views.callrecordings', compact('callrecordings'));   
        

我的刀片文件是

<table id="example" class="table table-bordered dt-responsive nowrap dataTable no-footer dtr-inline" style="width:100%">
        <thead>
            <tr>

                <th>Name</th>
                <th>Number</th>
                <th>Duration</th>
                <th>Size</th>
                <th>Direction</th>
                <th>Audio</th>
                <th>Download</th>
                <th>Timestamp</th>
            </tr>
        </thead>
        <tbody>
             @foreach ($callrecordings as $callrecording)
            <tr>

                <td> $callrecording->name </td>
                <td> $callrecording->phone</td>
                <td> $callrecording->duration</td>
                <td> $callrecording->size</td>
                <td>
                @if ($callrecording->direction === 'Incoming')  
                    <span class="label label-success">Incoming</span>
                @elseif ($callrecording->direction === 'Outgoing')  
                    <span class="label label-info">Outgoing</span>
                @elseif ($callrecording->direction === 'Rejected')
                    <span class="label label-warning">Rejected</span>
                @else
                    <span class="label label-danger">Missed</span>
                @endif
                </td>
                <td>
                    <audio id='sound1'>
                      <source src=" URL::to('/') /uploads/audio/ $callrecording->audio " type="audio/ogg">
                      <source src=" URL::to('/') /uploads/audio/ $callrecording->audio " type="audio/mpeg">
                    </audio>

                    <div class="play btn btn-success btn-xs" id="btn1">play</div>

                </td>
                <td>
                     <a href=" URL::to('/') /uploads/audio/ $callrecording->audio " download="proposed_file_name" class="btn btn-primary btn-xs"><i class="icon-download-alt"> </i> Download </a>

                    <!---button class="btn btn-primary btn-xs" data-download=" URL::to('/') /uploads/audio/ $callrecording->audio "><i class="fa fa-fw fa-download"></i> Download</button---->

                </td>

                <td> $callrecording->created_at </td>
            </tr> 
            @endforeach
        </tbody>
    </table>

此条件有效，但如果我在表中执行表状态 0 或没有增值，则会显示此错误消息正在尝试获取非对象的属性 'expiry_date'。

我附上了我的 dd($callrecordings);

请告诉我应该如何克服这个问题

提前致谢。

【参考方案1】：

您在代码中遗漏了一些内容，如果数据不存在，则检查 0 元素的数据，因此我们需要检查是否存在以进行记录

if(isset($callrecordings[0]->expiry_date) && $callrecordings[0]->expiry_date <= Carbon::now()->toDateTimeString())
