Overview

You can define your own validation rules, messages, and attributes for any AllowedType.
  • When a filter does not pass validation rules, a MalformedFilterFormatException is thrown.
  • MalformedFilterFormatException extends Laravels ValidationException.
    • You can let this bubble up to your controller for the default laravel 422 response.
  • This exception CAN be suppressed.
