Function set_value() not working as expected

[eluser]tison[/eluser]
For a quick fix, I've created this function to easily set empty rules - so that all fields get re-populated:

In /helpers/MY_form_helper.php

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Set empties
*
* Sets empty fields using set_value, hopefully they will fix this
*
*/
if ( ! function_exists('set_empty_rules'))
{
    function set_empty_rules($field_array)
    {
        if(isset($field_array) && is_array($field_array)):
            $mythis =& get_instance(); // grabbing our ci this instance
            foreach($field_array as $key => $val):
                $mythis->form_validation->set_rules($key,$val,'');
            endforeach;
        endif;
    }
}

And in your controller:

Code:

set_empty_rules(array('address'=>'Address','city'=>'City','state'=>'State','zip'=>'Zip'));

The function takes an array of key -> values where key = 'fieldname' and value='Field Error Message'
