在my attempts to find a way to pass a variable by reference to a blade @include ，我构建了一个简单的测试用例，它也证明了模板的执行顺序非常不稳定。 有没有办法在执行顺序很重要(特别是关于部分)的情况下使用带有变量的 Blade 模板？
testLayout.blade.php
<!DOCTYPE html>
<html>
<head>
</head>
<body>
{{"this is the layout: ".++$tabindex."<br>"}}
@include('testInclude')
{{"this is the layout after include: ".++$tabindex."<br>"}}
@include('testInclude',array('tabindex'=>$tabindex))
{{"this is the layout after passing include: ".++$tabindex."<br>"}}
@yield('testYield')
{{"this is the layout after yield: ".++$tabindex."<br>"}}
@section('testSection')
{{"this is the layout section: ".++$tabindex."<br>"}}
@show
{{"this is the layout after section: ".++$tabindex."<br>"}}
</body>
</html>
测试扩展.blade.php
@extends('testLayout')
{{"this is the extension: ".++$tabindex."<br>"}}
@include('testInclude')
{{"this is the extension after include: ".++$tabindex."<br>"}}
@include('testInclude',array('tabindex'=>$tabindex))
{{"this is the extension after passing include: ".++$tabindex."<br>"}}
@section('testYield')
{{"this is the extension yield: ".++$tabindex."<br>"}}
@stop
{{"this is the extension after yield: ".++$tabindex."<br>"}}
@section('testSection')
{{"this is the extension section: ".++$tabindex."<br>"}}
@parent
{{"this is the extension section after parent: ".++$tabindex."<br>"}}
@stop
{{"this is the extension after section: ".++$tabindex."<br>"}}
testInclude.blade.php
{{"this is the include: ".++$tabindex."<br>"}}
路由.php
Route::get('test', function(){
return View::make('testExtension',array('tabindex'=>0));
}); //I have used View::share in stead and the results are identical
this is the extension: 1
this is the include: 2
this is the extension after include: 2
this is the include: 3
this is the extension after passing include: 3
this is the extension after yield: 5
this is the extension after section: 8
this is the layout: 9
this is the include: 10
this is the layout after include: 10
this is the include: 11
this is the layout after passing include: 11
this is the extension yield: 4
this is the layout after yield: 12
this is the extension section: 6
this is the layout section: 13
this is the extension section after parent: 7
this is the layout after section: 14
看起来这些值是在扩展中计算的，然后在布局中计算，然后重新排序。因为这已经是另一个单独的问题，请忽略所有 @include 实例都是按值传递的，因此不会影响其包含文件中的值。我通常也不太关心部分之外的值，因为可以理解那里的行为更难预测。 这在部分中是有问题的。
如果布局对某个值执行任何操作，则该值将在计算完所有扩展值后计算，这是有问题的，因为执行顺序显然不会模仿输出顺序。为了让值按它们应该的方式运行，我可以在每个扩展中@overwrite所有适用的情况，首先打败了使用模板的意义，但是，在那种情况下，我会像在没有任何此类扩展的情况下定义每个 View 会很好。
有什么方法可以让这些部分按顺序运行，或者我真的可以只对值与顺序无关的事物使用模板吗？
最佳答案
模板与顺序无关。可以使用 @overwrite 覆盖部分，这意味着它们在加载所有内容时呈现，否则 @overwrite 可能会失败。
覆盖部分
默认情况下，部分会附加到该部分中存在的任何先前内容。要完全覆盖一个部分，您可以使用覆盖语句:
@extends('list.item.container')
@section('list.item.content')
<p>This is an item of type {{ $item->type }}</p>
@overwrite
