Form validation with Greater Than won't work with international currencies (comma separated decimal numbers)

You could create a callback and convert the number to a float and then do the comparison.
Haven't tested this, but the original conversion formula was found on php.net

Code:

public function greater_than_intl($str, $max)
{
  if (strpos($str, '.') !== FALSE && strpos($str, ',') !== FALSE && strpos($str, '.') < strpos($str, ','))
  {
    $str = str_replace('.', '',$str);
    $str = strtr($str,',', '.');          
  }
  else
  {
    $str = str_replace(',', '', $str);          
  }
      
  $str = float($str);

  $this->form_validation->set_message('greater_than_intl', 'The %s field must be greater than ' . $max);

  return ($str > $max);
}
