Redirect to Login if user not logged in Laravel

Question

i am new to laravel,

i have code in my controller's __construct like

if(Auth::check())
{
    return View::make('view_page');
}

return Redirect::route('login')->withInput()->with('errmessage', 'Please Login to access restricted area.');

its working fine, but what i wants is. its really annoying to put these coding in each and every controller, so i wish to put this Verify Auth and redirect to login page in one place, may be in router.php or filters.php.

I have read some posts in forum as well as in stackoverflow, and added code in filters.php like below but that's too not working.

Route::filter('auth', function() {
    if (Auth::guest())
    return Redirect::guest('login');
});

Please help me to resolve this issue.

Laravel 5.4

Use the built in auth middleware.

Route::group(['middleware' => ['auth']], function() {
    // your routes
});

For a single route:

Route::get('profile', function () {
    // Only authenticated users may enter...
})->middleware('auth');

Laravel docs

Laravel 4 (original answer)

That's already built in to laravel. See the auth filter in filters.php. Just add the before filter to your routes. Preferably use a group and wrap that around your protected routes:

Route::group(array('before' => 'auth'), function(){
    // your routes

    Route::get('/', 'HomeController@index');
});

Or for a single route:

Route::get('/', array('before' => 'auth', 'uses' => 'HomeController@index'));

To change the redirect URL or send messages along, simply edit the filter in filters.php to your liking.
