Php 未定义索引：在laravel中显示通知json数组时的用户

当尝试显示json数据时，它会给出未定义的索引：user exception

  foreach(auth()->user()->unreadnotifications as $notifications)

       @include('frontend.common.notification.'.snake_case(class_basename($notifications->type)))

  @endforeach

包含的视图代码是

  <div>
    <i class="fa fa-comment fa-fw"></i>
    <img src="{{url('images/account/'.$notifications->data['user']['currentimage'])}}" height="50px" width="50"/>
    {{$notifications->data['user']['email']}} commented on your post.
    <span class="pull-right text-muted small">{{$notifications->created_at->diffForHumans()}}</span>
</div>

数据['user']['currentimage']}}“height=“50px”width=“50”/
{{$notifications->data['user']['email']}对您的帖子发表了评论。
{{$notifications->created_at->diffForHumans（）}

Json对象是

{“评论”：{“评论”：“我很棒”，“用户id”：2，“发布id”：“2”，“通信率”：90，“更新地址”：“2017-07-06 16:32:07”，“创建地址”：“2017-07-06 16:32:07”，“id”：18}，“用户”：{“id”：2，“电子邮件”：”test2@mail.com“，“currentimage”：“1499004938.jpg”，“角色”：0，“已验证”：null，“已阻止”：null，“创建于”：“2017-07-02 13:44:24”，“更新于”：“2017-07-02 14:15:38”}”

在查看代码之后，我假设您正在集合上使用foreach循环

  <div>
<i class="fa fa-comment fa-fw"></i>
<img src="{{url('images/account/'.$notifications->user->currentimage}}" height="50px" width="50"/>
{{$notifications->user->email}} commented on your post.
<span class="pull-right text-muted small">{{$notifications->created_at->diffForHumans()}}</span>

用户->当前图像}}“height=“50px”width=“50”/
{{$notifications->user->email}}对您的帖子发表了评论。
{{$notifications->created_at->diffForHumans（）}
