From Concepts to Implementation: Understanding MVC in Laravel
MVC stands for Model View Controller which is a design pattern that separates an application into three main components:
Model:
represents the data and business logic of the application.
View:
responsible for displaying the data to the user.
Controller:
acts as a mediator between the Model and View, handling user input and updating the Model accordingly.
In Laravel, the MVC pattern is used to structure the application and make it more maintainable and scalable. Laravel provides various tools and components to implement MVC patterns effectively such as routing, middleware, controllers, models, views, etc.
Example of implementing MVC in Laravel:
Model: In Laravel, you can create a model using the Artisan command line interface:
php artisan make:model Product
This model represents the products in your application and can contain methods for retrieving and manipulating the product data.
- View: In Laravel, views are stored in the "resources/views " directory and written in Blade, Laravel s built-in templating engine. For example, you can create a view to display a list of products:
<h1>Products</h1>
<ul>
@foreach($products as $product)
<li>{{ $product->name }} </li>
</ul>
Controller: In Laravel, you can create a controller using the Artisan command line interface:
php artisan make:controller ProductController
this controller can obtain methods to handle the HTTP requests related to products such as displaying a list of products:
<?php
namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;
class ProductController extends Controller {
public function index()
{
$products = Product::all();
return view('products.index', compact('products'));
}
}
Finally, you can define a route in "routes/web.php" to map the URL to the corresponding method in the controller.
Route::get('/products' , [ProductController::class, 'index']);
with this setup, when a user visits the "/products" URL , the index method in the ProductController will be executed, which retrieves the rendered HTML to the user.
