如何在 Laravel blade @each 中获取迭代值？

Question

<ul>
    @foreach($users as $user)
        <li>{{ $loop->iteration }}</li>
        <li>{{ $user->name }}</li>
        <li>{{ $user->email }}</li>
    @endforeach
</ul>

进入：

<ul>  
    @each('user.list', $users, 'user', 'user.empty')
</ul>

list.blade.php

<li>{{ $loop->iteration }}</li>
<li>{{ $user->name }}</li>
<li>{{ $user->email }}</li>

empty.blade.php

<li>There is no user is users.</li>

但是，我在 {{ $loop->iteration }}

中收到错误“未定义的变量：循环”

那么，有什么方法可以在@each 中进行迭代吗？

Answer 1

如解释的那样in the documentation：

Views rendered via @each do not inherit the variables from the parent view. If the child view requires these variables, you should use @foreach and @include instead.

因此您的代码不会从处理循环的父视图继承 $loop 变量。

类似这样的方法可能有效：

@if (count($users)
    @foreach ($users as $user)
        @include("user.list", compact("user", "loop"))
    @endforeach
@else
    @include("user.empty")
@endif
