Validation with redirect?

[eluser]fakeempire[/eluser]
Hey guys -- I have a form I'm trying to use validation on but the form is dynamic.

http://sitename/event/register/<?= $event_id ?>

The form view pulls event specific stuff from the database depending on the event_id (title, date, description, etc). So there is not an actual 'form' view.

So if validation fails I cannot just

Code:

$this->view->load('form');

because I need to pass something more along the lines of

Code:

$this->view->load('form/<?= $event_id ?>')

which obviously doesnt work. I'm having to use a redirect

Code:

$this->validation->set_rules($rules);
    
      if ($this->validation->run() == FALSE)
      {
        redirect('/event/register/' . $event_id, 'refresh');
      }

But redirect doesn't pass the validation errors (or any variables for that matter (AFAIK)).
Could anyone shed some light on this for me? A possible solution or let me know if I going about this the wrong way.

Many thanks -
