Laravel Routing Basics and Advanced Usage

In web development, routers select paths and forward packets; similarly, framework routing handles HTTP request paths to invoke specific functionality, improving SEO by shortening URLs.

Default Route File

All Laravel routes are defined in the routes directory, automatically loaded by the framework. The primary file is routes/web.php.

use Illuminate\Support\Facades\Route;

Route::get('/', function () {

return view('welcome');

});

Basic Route

A simple route returning a string:

Route::get('index', function () {

return "study laravel";

});

Visiting localhost:8000/index displays "study laravel".

Common Route Methods

Beyond get, Laravel provides post, put, delete, any (matches all request methods), and match (specifies multiple methods).

Route::match(['get', 'post'], 'list', function () {

return 'list';

});

Parameter Passing

Routes can capture parameters, e.g., /news/1:

Route::get('news/{id}', function ($id) {

return 'news:' . $id;

});

To restrict {id} to digits:

Route::get('news/{id}', function ($id) {

return 'news:' . $id;

})->where('id', '\d+');

Multiple parameters with constraints:

Route::get('/name/{name}/age/{age}', function ($name, $age) {

echo "name:$name age:$age";

})->where(['name' => '\w+', 'age' => '\d+']);

Binding Routes to Controllers

Create a controller app/Http/Controllers/IndexController.php:

<?php

namespace App\Http\Controllers;

class IndexController extends Controller {

public function news($id) {

echo "news:$id";

}

}

Then bind the route:

Route::get('news/{id}', 'IndexController@news')->where('id', '\d+');

Accessing /news/1 now invokes the news method of IndexController.

If the controller resides in a sub‑namespace, e.g., app/Http/Controllers/Home/IndexController.php, set the route as:

Route::get('home', 'Home\IndexController@index');
