changing / rewriting the URI

[eluser]Rick Jolly[/eluser]
Something like this?

Code:

function listing($searchTerm1 = false, $searchTerm2 = false, $searchTerm3 = false)
{
   if (! empty($_POST))
   {
      $terms = '';

      if (! empty($_POST['searchTerm1']))
      {
         $terms .= '/' . urlencode($_POST['searchTerm1']);
      }
      if (! empty($_POST['searchTerm2']))
      {
         $terms .= '/' . urlencode($_POST['searchTerm2']);
      }
      if (! empty($_POST['searchTerm3']))
      {
         $terms .= '/' . urlencode($_POST['searchTerm3']);
      }
  
      $this->load->helper('url');
      redirect('info/listing' . $terms);
   }
   else
   {
      $searchTerm1 = (! empty($searchTerm1)) ? urldecode($searchTerm1) : false;
      $searchTerm2 = (! empty($searchTerm2)) ? urldecode($searchTerm2) : false;
      $searchTerm3 = (! empty($searchTerm3)) ? urldecode($searchTerm3) : false;

      // continue...
   }
}
