You can store validation_error() in a piece of flash data, then you can use header(Location) - or you could use the codeigniter redirect() function and fetch the flashdata in the redirected page.

Codeigniter has this functionality built in, why would you load the errors into flashdata and use header to redirect, makes no sense and isn't saving any resources over reloading the page in the controller.
