View and Template Engine in Laravel: Building Beautiful and Customizable Interfaces

Overview:
When developing web applications, the design and layout of the interface are usually is crucial. Laravel, as a popular PHP framework, provides a powerful view system and template engine, allowing developers to easily build beautiful and customizable interfaces. This article will introduce the views and template engine in Laravel and provide some sample code to help readers better understand and apply these concepts.

View:
In Laravel, the view is the part used to render the user interface. They are stored in the resources/views directory and can be referenced by simple file names. Views typically contain HTML markup and PHP code for displaying dynamic content and application logic.

Example 1: Create a simple view

First, we create a file named hello.blade.php and save it in the resources/views directory. The content of the file looks like this:

<html>
    <head>
        <title>Hello World</title>
    </head>
    <body>
        <h1>Hello, {{$name}}!</h1>
    </body>
</html>

Copy after login

In the above example, we used Laravel’s template engine syntax. We can insert dynamic content into the view by surrounding variables with two curly braces ({{ }}). In this example, we display a name using {{$name}}.

Here is the sample code of how to render the view in the route:

Route::get('/', function () {
    return view('hello', ['name' => 'John']);
});

Copy after login

In the above code, we use the view function to render the hello view and pass the variables in the form of associative array. Variables are automatically parsed and replaced by the view engine.

Template engine:
The template engine in Laravel is based on the Blade template engine. It provides a simple yet powerful set of tools that make it easier for you to build and manage templates. By using a template engine, you can design reusable interface components, include conditional branches and looping structures, and run simple expressions.

Example 2: Build a table using a template engine

Create a file named table.blade.php in the resources/views directory and set its content to the following code:

<table>
    <thead>
        <tr>
            <th>Name</th>
            <th>Email</th>
        </tr>
    </thead>
    <tbody>
        @foreach($users as $user)
            <tr>
                <td>{{$user->name}}</td>
                <td>{{$user->email}}</td>
            </tr>
        @endforeach
    </tbody>
</table>

Copy after login

In the above example, we use the @foreach directive of the Blade template engine to iterate through the user array and display the name and email in each row of the table.

Here is the sample code of how to render the table view in the controller:

public function showTable()
{
    $users = User::all();
    return view('table', ['users' => $users]);
}

Copy after login

In the above code, we get the array of all users from the database and pass it to the table view.

Conclusion:
Laravel’s view system and template engine provide developers with powerful tools to build beautiful and customizable interfaces. By using views and template engines, we can easily separate interface logic and application logic and provide reusable interface components. In this article, we introduce the basic concepts of views and template engines in Laravel and provide some sample code to help readers better understand and apply these concepts. I hope this article can help you learn and use Laravel views and template engines.
