added the server validations in routes.php with a post route using the laravel validation framework to validate all required fields with minimun lengh and numeric type when appropiate and making required the non-required fields if the enquiry type is 'Product complaint', if there's any error the page reloads itself with the appropiate error mesaages and the submited data so users can see the values they have previously entered (using the Input::old in the form fields of the view), otherwise the user is shown with a success message
