Laravel @extends和@include [英] Laravel @extends and @include
问题描述
我正在使用Laravel进行这个项目.
I'm working on this project using Laravel.
根据我正在观看的本教程，我必须在主视图的顶部添加以下代码.
According to this tutorial I'm watching, I had to add this bit of code at the top of the main view.
@extends('layouts.masters.main')
由于我是Laravel的新手，这让我想知道为什么我不能简单地使用它.
Since I'm new to Laravel this got me wondering why can i not simply use.
@include('layouts.masters.main')
我尝试了一下，它基本上做了同样的事情.唯一的事情是我确实知道include的工作原理，但是我真的不知道extends会做什么.
有区别吗，是的，这是什么.为什么辅导员选择@extends而不选择@include.
I tried it instead and it did the same thing basically. Only thing is i do know how include works but i don't really know what extends does.
Is there a difference and so yeah what is it. Why did tutorial guy go for @extends and not @include.
推荐答案
@include就像基本的PHP包含一样，它在您的视图中包括一个部分"视图.
@include is just like a basic PHP include, it includes a "partial" view into your view.
@extends允许您扩展"模板，该模板定义了自己的部分等.您可以扩展的模板将使用@yield定义自己的部分，然后您可以将自己的内容放入视图文件中
@extends lets you "extend" a template, which defines its own sections etc. A template that you can extend will define its own sections using @yield, which you can then put your own stuff into in your view file.
示例:
template.blade.php
<html>
<body>
@yield('header')
@yield('content')
@yield('footer')
</body>
</html>
view-one.blade.php
@extends('template')
@section('header')
View one's header
@endsection
@section('content')
View one's content
@endsection
@section('footer')
View one's footer
@endsection
这将导致:
<html>
<body>
View one's header
View one's content
View one's footer
</body>
</html>
现在，您可以创建另一个视图，该视图扩展相同的模板，但提供其自己的部分.
Now you could create another view which extends the same template, but provides its own sections.
使用@extend的另一个好处是继承.您可以提供一个基础模板，然后提供另一个扩展该子模板的子模板，该子模板随后将产生其自己的部分.然后，您可以扩展该子模板.
Another benefit to using @extend is inheritance. You could provide a base template, and then another child template that extends that one which subsequently yields it's own sections. You can then extend that child template.
