0 About about
1 Contact contact
2 Blog blog
what I am trying to do is to create dynamic routes in my : routes.php ?
Where if I go to for example: /about it will go to AboutController.php ( which will be created dynamically) is that possible? is it possible to create a dynamic controller file?
I am trying to create dynamic pages routes that links to a controller
example i want to generate this dynamically in my routes.php
Route::controller('about', 'AboutController');
Route::controller('contact', 'ContactController');
Route::controller('blog', 'BlogController');

This is not the right way to create dynamic pages instead, you should use a database and keep all pages in the database. For example:
// Create pages table for dynamic pages
id | slug | title | page_content
Then create Page Eloquent model:
class Page extends Eloquent {
// ...
}
Then create Controller for CRUD, you may use a resource controller or a normal controller, for example, normally a PageController:
class PageController extends BaseController {
// Add methods to add, edit, delete and show pages
// create method to create new pages
// submit the form to this method
public function create()
{
$inputs = Input::all();
$page = Page::create(array(...));
}
// Show a page by slug
public function show($slug = 'home')
{
$page = page::whereSlug($slug)->first();
return View::make('pages.index')->with('page', $page);
}
}
The views/page/index.blade.php view file:
@extends('layouts.master')
{{-- Add other parts, i.e. menu --}}
@section('content')
{{ $page->page_content }}
@stop
To show pages create a route like this:
// could be page/{slug} or only slug
Route::get('/{slug}', array('as' => 'page.show', 'uses' => 'PageController@show'));
To access a page, you may require url/link like this:
http://example.com/home
http://example.com/about
This is a rough idea, try to implement something like this.

After spending 2 hours, digging through google and Laravel source, I came up with this solution, which I think works the best and looks the cleanest. No need for redirects and multiple inner requests.
You add this route at the very bottom of routes files. If no other routes are matched, this is executed. In the closure, you decide which controller and action to execute. The best part is - all route parameters are passed to action, and method injection still works. The ControllerDispatcer line is from Laravel Route(r?) class.
My example would handle 2 cases - first checks if user exists by that name, then checks if an article can be found by the slug.
Laravel 5.2 (5.3 below)
Route::get('{slug}/{slug2?}', function ($slug) {
$class = false;
$action = false;
$user = UserModel::where('slug', $slug)->first();
if ($user) {
$class = UserController::class;
$action = 'userProfile';
}
if (!$class) {
$article= ArticleModel::where('slug', $slug)->first();
if ($article) {
$class = ArticleController::class;
$action = 'index';
}
}
if ($class) {
$route = app(\Illuminate\Routing\Route::class);
$request = app(\Illuminate\Http\Request::class);
$router = app(\Illuminate\Routing\Router::class);
$container = app(\Illuminate\Container\Container::class);
return (new ControllerDispatcher($router, $container))->dispatch($route, $request, $class, $action);
}
// Some fallback to 404
throw new NotFoundHttpException;
});
5.3 has changed how the controller gets dispatched.
Heres my dynamic controller example for 5.3, 5.4
namespace App\Http\Controllers;
use Illuminate\Routing\Controller;
use Illuminate\Routing\ControllerDispatcher;
use Illuminate\Routing\Route;
class DynamicRouteController extends Controller
{
/**
* This method handles dynamic routes when route can begin with a category or a user profile name.
* /women/t-shirts vs /user-slug/product/something
*
* @param $slug1
* @param null $slug2
* @return mixed
*/
public function handle($slug1, $slug2 = null)
{
$controller = DefaultController::class;
$action = 'index';
if ($slug1 == 'something') {
$controller = SomeController::class;
$action = 'myAction';
}
$container = app();
$route = $container->make(Route::class);
$controllerInstance = $container->make($controller);
return (new ControllerDispatcher($container))->dispatch($route, $controllerInstance, $action);
}
}
Hope this helps!

try
Route::get('/', ['as' => 'home', 'uses' => 'HomeController@index']);
$pages =
Cache::remember('pages', 5, function() {
return DB::table('pages')
->where('status', 1)
->lists('slug');
});
if(!empty($pages))
{
foreach ($pages as $page)
{
Route::get('/{'.$page.'}', ['as' => $page, 'uses' => 'PagesController@show']);
}
}

There is a component available, which you can use to store routes in a database. As an extra advantage, this component only loads the current active route, so it improves performance, since not all routes are loaded into the memory.
https://github.com/douma/laravel-database-routes
Follow the installation instructions provided in the readme.
Storing routes in the database
The only thing needed here is injecting the RouteManager into for example a cli command. With addRoute can tell the RouteManager to store the route into the database. You can easily change this code and use your own repository of pages or other data to construct the routes.
use Douma\Routes\Contracts\RouteManager;
class RoutesGenerateCommand extends Command
{
protected $signature = 'routes:generate';
private $routeManager;
public function __construct(RouteManager $routeManager)
{
$this->routeManager = $routeManager;
}
public function handle()
{
$this->routeManager->addRoute(
new Route('/my-route', false, 'myroute', MyController::class, 'index')
);
}
}
Run this cli command every 2-5 minutes or after a change in your data to make sure the routes are recent.
Register the RouteMiddleware in App\Http\Kernel.php
\Douma\Routes\Middleware\RouteMiddleware::class
Empty your web.php
If you have defined any Laravel route, make sure to empty this file.
Using routes from the database
You can use the route in blade:
{{ RouteManager::routeByName('myroute')->url() }}
Or you can inject the RouteManager-interface anywhere you like to obtain the route:
use Douma\Routes\Contracts\RouteManager;
class MyClass
{
public function __construct(RouteManager $routeManager)
{
$this->routeManager = $routeManager;
}
public function index()
{
echo $this->routeManager->routeByName('myroute')->url();
}
}
For more information see the readme.
