Form Validation and repopulating the form (set_value)

[eluser]TheFuzzy0ne[/eluser]
I made a mess of my last post, so allow me to re-iterate on the things that were a bit fuzzy®.

The form helper class is just an extension of $this->form_validation->set_value().

The form validation library works directly on $_POST, so really, set_value only relies on the post variable having been set to return a value. If the post variable hasn't been set, a default is used if you've supplied one.

That makes more sense to me now, so hopefully it also makes sense to you to.
