[quote author="bugboy" date="1259337870"]Well after digging around in the form_validation library i found this function call
// Now we need to re-set the POST data with the new, processed data
$this->_reset_post_array();
So it looks like the post data is updated after the form validation is run
After the validation is done the post data is updated with a $this->input->post('field);[/quote]
Like I said, set_value().
