What is MVC?
MVC stands for Model-View-Controller, a software design pattern used to organize code by separating concerns into three distinct components:
- Model: Handles the business logic and database communication. It is responsible for fetching, storing, and processing data.
- View: Manages the presentation layer and is responsible for displaying data to the user in a readable format.
- Controller: Handles user inputs, processes requests, and determines which data should be sent to the View.
Laravel, a popular PHP framework, follows the MVC architecture, providing developers with a structured way to build scalable and maintainable web applications.
How to Create a View in Laravel
A View in Laravel is typically a Blade template file that resides in the resources/views directory. Here’s how you can create a View:
Example of a View (resources/views/example.blade.php)
<!DOCTYPE html>
<html>
<head>
<title>Example Page</title>
</head>
<body>
<h1>Welcome to Laravel</h1>
<p>This is an example view.</p>
</body>
</html>
How to Create a Controller in Laravel
A Controller in Laravel is a PHP class that handles the application logic. Here’s how to create one:
1. Use the Artisan Command
Run the following command in your terminal to create a controller:
php artisan make:controller ExampleController
2. Locate the Controller
The newly created controller will be in the app/Http/Controllers directory.
3. Define a Method in the Controller
Open the controller file and add methods for handling requests:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class ExampleController extends Controller
{
public function showExample()
{
return view('example');
}
}
Connecting the Controller to a Route
After creating a controller method, you need to define a route to access it.
Define the Route in routes/web.php
use App\Http\Controllers\ExampleController;
Route::get('/example', [ExampleController::class, 'showExample']);
Now, when a user visits www.example.com/example, Laravel will execute the showExample method in ExampleController and return the example.blade.php view.
Conclusion
The MVC pattern in Laravel makes it easier to build and maintain web applications by separating logic (Model), presentation (View), and user interactions (Controller). By using Blade templates for Views, controllers for request handling, and routes for defining endpoints, Laravel provides a clean and efficient development experience.
