set_value not working??

[quote author="dizzyagain" date="1279582898"]Or you could follow Jermomes lead (in this bug report) and override the set_value function in your own form helper so that it will re-populate a field even if a validation rule doesn't exist for it.

Here is the code:

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

/**
* Form Value
*
* Grabs a value from the POST array for the specified field so you can
* re-populate an input field or textarea.  If Form Validation
* is active it retrieves the info from the validation class
*
* @access   public
* @param   string
* @return   mixed
*/
if ( ! function_exists('set_value'))
{
  function set_value($field = '', $default = '')
  {
      $OBJ =& _get_validation_object();

      if ($OBJ === TRUE && isset($OBJ->_field_data[$field]))
      {
        return form_prep($OBJ->set_value($field, $default));
      }
      else
      {
        if ( ! isset($_POST[$field]))
        {
          return $default;
        }

        return form_prep($_POST[$field]);
      }
  }
}

/* End of file MY_form_helper.php */
/* Location: ./application/helpers/MY_form_helper.php */

[/quote]

With this is one problem:

Code:

Example ' "

change into

Code:

Example  ' "

next into

Code:

Example ' "

and etc..

I deleted form_prep from last line with return but i am not sure is it good idea.
