            Route::get('/all-post', function () {return view('a.all_post'); });



});

Answer 1

you set an 404 route using this.then use any view file in that route

App::error(function(Exception $exception, $code)
{
Log::error($exception);

if (Config::get('app.debug') == false) {
    return Redirect::route('404');
}
});

Answer 2

update 13.11.2017

just make 404.blade.php page in /resources/views/errors/ folder and that page will be shown if a route does not exist

---

instead of laravel error for non existing route:

Sorry, the page you are looking for could not be found.
1/1 NotFoundHttpException in RouteCollection.php line 161:

1. make 404.blade.php page in /resources/views/errors/ folder

and then just call it with

abort(404);

For example make a route like this:

Route::get('/404', function () {
    return abort(404);
});

Answer 3

You can use the abort(); method and create a view into the error folder, just as explained in the documentation.

Laravel will automatically fetch the error page there and display it.

Answer 4

Try this:

abort(404);
