Auction Product Type

[Toft]

Correction to the abowe.
I have a mod in an other file, so the abowe correction will probably not work for you. Sorry ....

So use this in stead. It should work wheather you have the product with or without tax.

In includes/modules/pages/product_auction_info/header_php.php
fine about between lines 20 and 25

require(DIR_WS_MODULES . 'require_languages.php');
$process = false;
if (isset($_POST['action']) && ($_POST['action'] == 'place_bid')) {
  $process = true;
  $auction_bid = zen_db_prepare_input($_POST['auction_bid_amount']);
  $auction_bid = zen_round($auction_bid,  $currencies->currencies[$_SESSION['currency']]['decimal_places']);
  $auction_price  = zen_db_prepare_input($_POST['auction_price']);
  $auction_current_bid  = zen_db_prepare_input($_POST['auction_current_bid']);
  $auction_current_bid = ($auction_current_bid > 0) ? $auction_current_bid : 0.01;
  $products_id = zen_db_prepare_input($_GET['products_id']); 

Change to:

require(DIR_WS_MODULES . 'require_languages.php');
$process = false;

    $sql = "select p.products_id,
                  p.products_tax_class_id
           from   " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_PRODUCT_AUCTION_EXTRA . " pae
           where  p.products_status = '1'
           and    p.products_id = '" . (int)$_GET['products_id'] . "'
           and    pd.products_id = p.products_id and p.products_id = pae.products_id
           and    pd.language_id = '" . (int)$_SESSION['languages_id'] . "'";

    $product_info = $db->Execute($sql);
$site_tax = zen_get_tax_rate($product_info->fields['products_tax_class_id']);

if (isset($_POST['action']) && ($_POST['action'] == 'place_bid')) {
  $process = true;
  $auction_bid = zen_db_prepare_input($_POST['auction_bid_amount']);
  $auction_bid = zen_round($auction_bid,  $currencies->currencies[$_SESSION['currency']]['decimal_places']);
  $auction_price  = zen_db_prepare_input($_POST['auction_price']);
  $auction_current_bid  = zen_db_prepare_input($_POST['auction_current_bid']);
  $auction_current_bid = ($auction_current_bid > 0) ? $auction_current_bid : 0.01;
  $products_id = zen_db_prepare_input($_GET['products_id']);
   if ($site_tax > 0) {
  $auction_bid = $auction_bid * "100" / sprintf("1".$site_tax);
   }
