PHP Laravel 4 - before & after action

We may need to perform some actions before the controller function get called.

For example

Check user authentication before access to certain page.

AccountController.php

<?php
class AccountController extends BaseController
{
    ...

    public function __construct()
    {
        parent::__construct();

        // before goes into certain function, check for authentication
        $this->beforeFilter('auth');
    }
}

The filter function is in

app/filters.php

<?php
...
Route::filter('auth', function()
{
    if (Auth::guest()) return Redirect::to('login');
}
