Question

我在mysql text字段中有这些数据：

{"message":"New comment from pp on one of your photos.","action":"\/photos\/9372"}

使用此功能（laravel通知）将其写入数据库：

public function toArray($notifiable)
{
    return [
        'message' => 'New comment from '.Auth::user()->username.' on one of your photos.',
        'action' => '/photos/'.$this->comment->photo_id
    ];
}

documentation说：

"The returned array will be encoded as JSON and stored in the data column of your notifications table."

然后我获取这样的数据：

$notifications = Auth::user()->notifications()->paginate(30);

return view('home.index')->with('notifications',$notifications);

如何在刀片视图中显示此json array（？）的内容？我可以var_dump()但不能显示。它总是undefinded index或其他错误。

@forelse($notifications as $n)
    @php
        $data = $n->data;
    @endphp
    {!! var_dump($data) !!}
@empty
    nothing
@endforelse

当我尝试json_decode数据时，它告诉我，它是一个数组：

{!! var_dump(json_decode($data)) !!}

json_decode() expects parameter 1 to be string, array given

print_r()说同样的话：

{!! print_r($data) !!}

Array ( [message] => New comment from pp on one of your photos. [action] => /photos/9372 ) 1

var_dump()说它是一个数组：

{!! var_dump($data) !!}

array(2) { ["message"]=> string(42) "New comment from pp on one of your photos." ["action"]=> string(12) "/photos/9372" }

但是当我想显示某个值时，它不起作用：

{!! $data["message"] !!}

Undefined index: message

当您尝试访问数组的消息部分时，请确保循环遍历通知数组：

@foreach ($notifications as $notification)
    {{ $notification->data['message'] }}
@endforeach
