嘿，因为我正在传递一个具有自己的控制器的刀片视图，我也将它包含在没有自己的控制器的视图中。它给了我一个未定义的变量错误，任何人都可以帮助我如何解决。

我有一个没有任何控制器的视图，Route::get('index', function () { return view('index'); });在这个视图中只有这样的 Route我正在传递另一个视图，它有自己的控制器，也有一些来自数组的数据。但在视图中使用此视图后，我收到未定义的变量错误。

two steps.
两步。
Declare & transfer $variableto View from Controllerfunction.
public function index() { return view("index", [ "variable" => $variable ]); }
Indicate where transferred $variablefrom Controllerappear in view.blade.php.
{{ $variable }}
从控制器函数声明并传输$variable到 View 。
public function index() { return view("index", [ "variable" => $variable ]); }
指示从Controller传输的$variable出现在view.blade.php 中的位置。
{{ $变量}}
if you don't make sure, $variable is transferred or not
如果你不确定， $variable 是否被转移
{{ isset($variable) ? $variable : '' }}

You can try this:
你可以试试这个：
public function indexYourViews()
{
$test = "Test Views";
$secondViews = view('second',compact('test'));
return view('firstview',compact('secondViews'));
}
and after declare {{$secondViews}}in your main view file(firstview).
并{{$secondViews}}在您的主视图文件（firstview）中声明之后。
Hope this helps you.
希望这对你有帮助。

public function returnTwoViews() {
$variable = 'foo bar';
$innerView = view('inner.view', ['variable' => $variable]);
return view('wrapper.view, ['innerView' => $innerView]);
}
This may be what you are looking for?
这可能是您要找的？
... inside your wrapper.view template:
...在您的 wrapper.view 模板中：
{!! $innerView !!}
EDIT: to answer the question in the comment: In order to fetch each line you for do this inside your $innerViewview:
编辑：回答评论中的问题：为了获取您在$innerView视图中执行此操作的每一行：
@foreach($variable as $item)
{{ $item }}
@endforeach
... and in the wrapper view it will still be {!! $innerView !!}
...在包装视图中它仍然是 {!! $innerView !!}
