Laravel is one of the most popular PHP frameworks currently, and its powerful view generation capabilities are impressive. A view is a page or visual element displayed to the user in a web application, which contains code such as HTML, CSS, and JavaScript. Laravel View allows developers to use a structured template language to build web pages and generate corresponding views through controllers and routing. In this article, we will explore how to generate views using Laravel View.

1. What is Laravel View

Laravel View is one of the components in the Laravel framework used to generate application user interfaces. Using Laravel View, we can use a structured template language to build pages, which can contain PHP expressions, logic controls, loop structures, etc. Laravel View makes it easier to separate application business logic and user interface.

2. Create a view

In Laravel View, it is very easy to create a view. We can generate a view using the artisan command provided by the Laravel framework. Just open a command line terminal and enter the following command:

php artisan make:view myview

Copy after login

After running this command, Laravel will create a new folder myview in the resources/views directory for us, which contains view.blade.php document. In this file we can build our template.

We can also create a new view manually, just create a new folder in the resources/views directory and create a new view.blade.php file in the folder. In the file.blade.php file we can start writing our HTML and template code.

3. Rendering Views

Once we create the view file, before creating the view, we need to understand how to use the view. In Laravel View, we can use the template engine Blade to access the view. In order to access the view.blade.php file under the myview folder, we can use the following code in the controller:

return view('myview.view');

Copy after login

This code will load the view.blade.php file under the myview folder and display it on the Web The file is rendered in the application.

4. Pass data to the view

When we render the view, we may need to pass dynamic data to the view. In Laravel, we can pass data using the second parameter of the view function. In the controller, we can pass the data to the view using the following code:

$data = ['title' => 'Laravel View Tutorial', 'content' => 'Learn how to use Laravel View.'];

return view('myview.view', $data);

Copy after login

In the view, we can wrap the data using { { } } to output their values:

<h1>{ { $title } }</h1>
<p>{ { $content } }</p>

Copy after login

five , Use Blade template engine

Blade is the default template engine of the Laravel framework. Blade has many features such as conditional and loop statements, layouts and blocks, etc. Let's introduce some of the features of Blade template engine below.

① Conditional statements

The conditional statements in the Blade template engine allow us to output content according to different situations. For example, the following code will output different statements based on the value of the $total variable:

@if ($total > 100)
<p>Your total is: {{ $total }}</p>
@else
<p>You didn't spend enough!</p>
@endif

Copy after login

② for loop statement

The Blade template also supports for loop statements. The following code will loop through each item of the variable $items and output their values:

<ul>
    @foreach ($items as $item)
        <li>{{ $item }}</li>
    @endforeach
</ul>

Copy after login

③ Block

We can use blocks to define specific parts of a template. These sections typically contain layout elements such as headers, footers, or menus. We can define and insert sections by using the directives @section and @show.

In the view, we can use the @section and @show directives to define and insert blocks. For example:

view.blade.php

@section('content')
    This is my content.
@show

Copy after login

layout.blade.php

<html>
<head>
    <title>My Layout</title>
</head>
<body>
    @yield('content')
</body>
</html>

Copy after login

In the above example, view.blade.php defines a content named block and how to use it is defined in the template layout.blade.php. The @yield directive will display the content of the content block in the template.

6. Summary

Laravel View allows us to create and render views very easily. Views allow us to separate the application's business logic and user interface. In addition, Laravel View also provides a powerful Blade template engine, which makes it easier for us to write efficient and powerful templates. When using Laravel for web application development, it is necessary to be proficient in Laravel View and Blade template engines.
