                {!! Form::submit('Submit', array('class'=>'send-btn')) !!}
                {!! Form::close() !!}
            </div>
        </div>
    </div>
@endsection

Controllers/UploadController.php:

<?php namespace App\Http\Controllers;
use Illuminate\Support\Facades\Input;
use Validator;
use Redirect;
use Request;
use Session;
class UploadController extends Controller {

    public function upload() {
        $file = array('image' => Input::file('image'));
        $rules = array('image' => 'required',); 
        $validator = Validator::make($file, $rules);
        if ($validator->fails()) {
            return Redirect::to('movies')->withInput()->withErrors($validator);
        }
        else {
            if (Input::file('image')->isValid()) {
                $destinationPath = 'public.uploads'; 
                $extension = Input::file('image')->getClientOriginalExtension();
                $fileName = rand(11111,99999).'.'.$extension;
                Input::file('image')->move($destinationPath, $fileName);
                Session::flash('success', 'Upload successfully');
                return Redirect::to('movies');
            }
            else {
                Session::flash('error', 'uploaded file is not valid');
                return Redirect::to('movies');
            }
        }
    }
}

and finaly, my routes.php:

<?php



Route::get('/', function () {
    return view('landingpage');
});

Route::auth();

Route::get('/home', 'PublicController@nav2index');
Route::get('/movies', 'PrivateController@nav2movies');
Route::post('movies', 'UploadController@upload');

Hope someone can tell me, where to find the error... Thank you guys.
