In the following book page i will theme a CCK Contenttyp in 3 different ways. First I post the Contenttyp: This should be a bill which could the sent to an client, therefore I have the following fields title field_client // A node reference to a contenttyp called client to get the adress data etc. field_seller // A user reference to a roll called seller, so that you can have a analyze of your workers field_bill_text // A text to the client which is added to the bill field_pay_date // A Date on which the client has to pay, this could be f.e. used for views field_a_nr // A node reference to a contenttyp called article to get the description, the price per article field_a_count // How many articles, on aboves type was salled; perhaps you could add a functionality whether there are some articles, which are availible field_bill_me // ME = Mailing exchanges, how many should be added to the price This fields are supplemented with a lot of computed fields , f.e. one for getting the price per article

 field_a_nr); $i ++)
{
$article = node_load($node->field_a_nr[$i]['nid']);
$node_field[$i]['value'] = $article->field_price[0]['value'];
}
?>

or for summand all articles to an end price


field_r_articleprice); $i ++)
{
  if (is_numeric($node->field_r_articleprice[$i-1]['value']))
{
  if (is_numeric($node->field_a_count[$i-1]['value']))
  {
    $node_field[$i-1]['value'] = $node->field_r_articleprice[$i-1]['value']*$node->field_a_count[$i-1]['value'];
  }
}
}
?>

bill-edit.php The second theme displays the form as Tabs with JSTabs in JSTools

2.bill-edit.tpl.php The third theme displays the form like the standard way but with a css class .item. This class is used by jquery to hide, first each element, and than show the next form by clicking the next link or the key [page down] First you have nothing
