How to use laravel inheritance
Laravel is a popular web application framework that provides many convenient functions and tools to help us quickly develop high-quality applications. These features and tools allow developers to quickly create and maintain web applications. An important feature of Laravel is view inheritance.
View inheritance is a very useful feature in Laravel for web application development, which allows sharing the same view layout and code blocks across multiple views. This feature can reduce redundant code and improve code reusability, while also facilitating developers' coding work.
This article will introduce in detail how to use view inheritance in Laravel.
Step 1: Create the main view file
First, we need to create a main view template and define the shared layout and code blocks on the template. In a Laravel application, the main view file is usually named layout.blade.php as shown below:
<!DOCTYPE html>
<html>
<head>
<title>@yield('title')</title>
</head>
<body>
<div class="container">
@yield('content')
</div>
</body>
</html>In this code, we define an HTML layout that includes a common page container, This container is where we place the content we pass to the main template as subviews.
In addition, we used the @yield directive in Laravel to define placeholders that can be replaced in subviews. For example, @yield('title') will be replaced by the title from the subview.
Step 2: Create the subview file
Next, we need to embed the subview file in the main view to share the layout and code blocks. In Laravel, you can use the @extend directive to inherit the basic layout, for example:
@extends('layout')
@section('title', 'Page Title')
@section('content')
<p>This is my page content.</p>
@endsectionIn this code snippet, we use the @extends directive to explicitly inherit the layout.blade.php layout template. Then, we use the @section and @endsection directives to define a subview content that will be inserted into the main layout. The
@section directive defines a code block and defines the name of the code block. This code block can be used elsewhere, such as in the main layout to place content. Here is a more complete example:
@extends('layout')
<!-- 定义页面标题 -->
@section('title', 'Page Title')
<!-- 子视图片段内容 -->
@section('content')
<p>This is my page content.</p>
@endsection
<!-- 子视图片段，显示在顶部 -->
@section('header')
<h1>Welcome to my Site</h1>
<nav>
<ul>
<li><a href="/">Home</a></li>
<li><a href="/about">About</a></li>
<li><a href="/contact">Contact</a></li>
</ul>
</nav>
@endsection
<!-- 子视图片段，显示在底部 -->
@section('footer')
<p>© 2021 My Site</p>
@endsectionIn this example, we define three code blocks starting with the @section directive: title, content, header, and footer. We can define everything we need in these code blocks as needed.
When the view is rendered, these instructions will be processed and the corresponding placeholders will be replaced with corresponding content.
Finally, we need to pass the subview file to the view renderer so that it can render the entire page through the main view. View functions can be used in Laravel to pass the rendered view name as well as the data in the representative view:
return view('page');In this example, we use the view function to pass the page view to the view renderer, which will be included in layout.blade.php layout template and rendered as final view.
Conclusion
Laravel is a very powerful web development framework that provides developers with many tools and features for rapid web application development.
One of the important features is view inheritance, which can easily organize the code of a web application and make the code more concise, clear and easy to maintain.
In this article, we covered how to use view inheritance in Laravel, including how to create main views and subviews, and how to pass them to the view renderer.
Using view inheritance is an integral part of Laravel web application development, and mastering it will have a significant impact on your web development process.

PHP and Laravel are not directly comparable, because Laravel is a PHP-based framework. 1.PHP is suitable for small projects or rapid prototyping because it is simple and direct. 2. Laravel is suitable for large projects or efficient development because it provides rich functions and tools, but has a steep learning curve and may not be as good as pure PHP.
