redirect('dashboard', $data)

If the method is at another controller, you just need to pass it a URI that the other controller method knows how to parse, like beemr said. "Controller Forwarding" seems a bit odd because the destination controller method should already be getting its information from the URI, so requesting the correct URI ought to work just fine. If you need to share data between the current request and the redirect, use session flashdata
