Question

我目前正在尝试使用 laravel 5.4 设置我的刀片布局，但在使用它时，我似乎遇到了@empty语句的问题with loops

我尝试使用的代码是：

@foreach ($notifications as $notification)
    <li data-for='{{ $notification->lobbyid }}'>
        @if ($notification->approved == 1) 
             <div class='notification-text'><strong>{{ $notification->sentBy }}</strong> wants access to your lobby:  \"{{$notification->title}}\".</div>
             <div class='notification-actions' id='HI' data-for='{{ $notification->lobbyid }}' data-userid='{{ $notification->userid }}'><span data-type='{ \"as\": \"requesting\", \"action\": 1 }'>Accept</span><span data-type='{ \"as\": \"invited\", \"action\": 0 }'>Deny</span></div> 
        @else 
            <div class='notification-text'><strong>{{ $notification->sentBy }}</strong> invites you to join his lobby: \"{{$notification->title}}\".</div>
            <div class='notification-actions' id='HI' data-for='{{ $notification->lobbyid }}' data-userid='{{ $notification->userid }}'><span data-type='{ \"as\": \"invited\", \"action\": 1 }'>Accept</span><span data-type='{ \"as\": \"invited\", \"action\": 0 }'>Deny</span></div>      
        @endif
     </li>
@empty
    <li>No Notifications</li>
@endforelse

我收到以下错误：

未定义的变量：__ empty_0

单独使用时效果很好：

@endforeach

@empty($notifications)
    <li>No Notifications</li>
@endempty

但我想在laravel文档中使用更清晰的语法。

Answer 1

@foreach ($notifications as $notification)

它应该是@forelse而不是@foreach

@empty给出＆＃34;未定义的变量：__ empty_0＆＃34;
