Laravel 的 Blade 模板 @yield 和 @section 是如何工作的？
[英]Laravel's Blade template @yield and @section how does it work?
问题描述
I'm new to Laravel and want to learn how to use the Blade template system properly, but i cant wrap my head around the difference between @section and @yield.
我是 Laravel 的新手，想学习如何正确使用 Blade 模板系统，但我无法理解 @section 和 @yield 之间的区别。 I've been reading the docs : https://laravel.com/docs/5.7/blade .我一直在阅读文档： https : //laravel.com/docs/5.7/blade 。
But it's not explaining the differences and how to use them properly.但这并没有解释差异以及如何正确使用它们。 I've been reading posts in other forums too like this one :我一直在阅读其他论坛上的帖子，就像这样：
https://laravel.io/forum/09-02-2014-using-section-and-yield https://laravel.io/forum/09-02-2014-using-section-and-yield
But still i'm a bit confused.但我还是有点困惑。
For example right now i'm creating an app that have multiple pages with commun pieces between them, so for now i get that i have to create a common layout for this pages, but when to use @section and when do i have to use @yield ?例如，现在我正在创建一个应用程序，它有多个页面，它们之间有公共部分，所以现在我知道我必须为此页面创建一个通用布局，但是何时使用 @section 以及何时必须使用@屈服 ？
for example if i have a page like so :例如，如果我有一个这样的页面：
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<title>{{ config('app.name', 'Name') }}</title>
//Common CSS between pages
<link href="{{ asset('css/style1.css') }}" rel="stylesheet">
//Changing CSS between pages
<link href="{{ asset('css/style2.css') }}" rel="stylesheet">
</head>
<body>
//the content stay the same !
<div id="app">
<span id="some_style">hello world !</span>
</div>
<script>
//common JS
<script src="{{ asset('script1.js') }}">
//Changing JS between pages
<script src="{{ asset('script2.js') }}">
</script>
</body>
</html>

Assuming you 2 templates. 假设您有2个模板。 Lets call one Base.blade.php and the other one Posts.blade.php . 让我们调用一个Base.blade.php和另一个Posts.blade.php 。
We'll @extends('base') in Posts . 我们将在Posts @extends('base') 。
Using @section in Posts and @yield in Base . 在Posts使用@section和在Base使用@yield 。
Something like this: 像这样：
Base
@yield('posts') {# the section called "posts" #}
Posts
@extends('base')
@section('posts')
Here be posts
@endsection
Whatever is written in posts will be yielded in the base blade. 无论写在posts都将在基本刀片中yielded 。
Think of it as inheritance. 将其视为继承。
You can imagine it as classes if you will. 您可以将它想象成类。 Where the child class calls a method in the base class. 子类在基类中调用方法的位置。
class Base {
protected function printSomething($something) {
echo $something;
}
}
class Posts extends Base {
public function BaseWillPrint() {
$this->printSomething('POSTS');
}
}
Basically I haven't told you anything that doesn't already exist in the documentation. 基本上，我没有告诉过您文档中尚不存在的任何内容。

Yes, assuming if you have a template you can make the base of template in layouts/app.blade/php and you can make the @yield('anything') and then in your views/main.blade.php you must give @extends('layouts.app') and是的，假设你有一个模板，你可以在layouts/app.blade/php中制作模板的基础，你可以制作@yield('anything')然后在你的views/main.blade.php你必须给@extends('layouts.app')和
@section('anything')
*for dynamic page
@endsection
