How to display JSON Array in Blade view?
提问by rmdy
I'm using a view composer to get data from this table and send it back to my view
我正在使用视图编辑器从该表中获取数据并将其发送回我的视图
class NavComposer
{
public function compose(View $view)
{
if (Auth::check()) {
$view->with('unread_notifications', DB::table('notifications')->where([
['read_at', '=', NULL],
['notifiable_id', '=', Auth::user()->id],
])->get());
}
}
}
My view:
我的看法：
@foreach($unread_notifications as $notification)
{{ $notification->data }}
@endforeach
What I am getting:
我得到了什么：
{"id":79,"sender":"Diana","receiver":"Alex","subject":"Subject","body":"Lorem ipsum"}
What I want to display:
我想显示的内容：
ID: 79
Subject: Subject
Body: Lorem Ipsum
I apologize in advance if this is very simple stuff I dont know much about JSON
如果这是非常简单的东西，我提前道歉，我对 JSON 不太了解

You need to decode JSON. You can do this manually:
您需要解码 JSON。您可以手动执行此操作：
@foreach($unread_notifications as $notification)
<?php $notificationData = json_decode($notification->data, true); ?>
{{ $notificationData['sender'] }}
@endforeach
Or you can create accessorso Laravel could automatically convert JSON to an array:
或者您可以创建访问器，以便 Laravel 可以自动将 JSON 转换为数组：
public function getDataAttribute($value)
{
return json_decode($value, true);
}

@foreach($unread_notifications as $notification)
@foreach(json_decode($notification->data, true) as $d)
<div>ID: {{ $d['id'] }}</div>
<div>Subject: {{ $d['subject'] }}</div>
<div>Body: {{ $d['body'] }}</div>
@endforeach
@endforeach
