未定义的索引：当我在 laravel 中显示通知 json 数组时的用户

Posted 2023-03-15

【中文标题】未定义的索引：当我在 laravel 中显示通知 json 数组时的用户

【英文标题】：Undefined index: user when I display notification json array in laravel

【问题描述】：

当尝试显示 json 数据时，它会给出未定义的索引：用户异常

  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'])"  />
    $notifications->data['user']['email'] commented on your post.
    <span class="pull-right text-muted small">$notifications->created_at->diffForHumans()</span>
</div>

Json 对象是

"comment":"comment":"我很棒","user_id":2,"post_id":"2","commment_rate":90,"updated_at":"2017-07-06 16 :32:07","created_at":"2017-07-06 16:32:07","id":18,"user":"id":2,"email":"test2@mail. com","currentimage":"1499004938.jpg","role":0,"verified":null,"blocked":null,"created_at":"2017-07-02 13:44:24","updated_at ":"2017-07-02 14:15:38"

【参考方案1】：

查看您的代码后，我假设您正在对集合使用 foreach 循环。

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