• Integrating Sales Analytics/Affiliates Tools

    On the "checkout_success" page, there are several pieces of data available:

    • $order_summary['order_number'] = The current order number
    • $order_summary['order_subtotal'] = The subtotal of the price of all products in the cart, before shipping etc
    • $order_summary['credits_applied'] = A sum of all discounts/credits applied to the order (ie: handled by "credit" ot modules such as coupons and gift certificates and customer-group-discounts etc)
    • $order_summary['commissionable_order'] = The amount of the purchase that is commissionable, ie: subtotal minus discounts
    • $order_summary['commissionable_order_formatted'] = Formatted according to the current currency
    • $order_summary['coupon_code'] = The coupon code used in this order, if any
    • $order_summary['currency_code'] = The currency used when making this sale
    • $order_summary['currency_value'] = The exchange rate applied while using this currency
    • $order_summary['payment_module_code'] = The payment module used to facilitate payment
    • $order_summary['shipping_method'] = The shipping method selected by the customer
    • $order_summary['orders_status'] = The status number denoting the order's status in the system
    • $order_summary['tax'] = The amount of tax on the order
    • $order_summary['shipping'] = The shipping cost
    • $order_summary['order_total'] = The final/net total of the order, the amount for payment
      Also available starting with ZC v1.5.5 are the following (or add them to older versions using the extra PHP code shown below the following examples)
    • $order_summary['products_ordered_models'] = a list of product model numbers, delimited by '|'
    • $order_summary['products_ordered_ids'] = a list of product ID numbers, delimited by '|'

    An analytics or affiliate-tracking system can use these variables as part of their tracking-pixel or other callback notification by simply referencing these variables in their callback/tracking code.
    (Advanced tip: If passing product ID/model numbers needs a different delimiter in your system, simply do a replacement on it while doing your output, such as: str_replace('|', '@', $order_summary['products_ordered_models']) if you wanted to replace | with @, for example.)


    No need to edit any core Zen Cart files.
    Simply create a new file: /includes/modules/pages/checkout_success/jscript_idevaffiliate.php ... be sure to set the correct URL for your iDevAffiliate system, and appropriate profile number:
      echo '<script type="text/javascript" src="http://www.yourdomain.com/idevaffiliate/sale.php?profile=1&idev_saleamt=' . $order_summary['commissionable_order_formatted'] . 
           '&idev_ordernum=' . $order_summary['order_number'] . '&products_purchased=' . $order_summary['products_ordered_models'] . '&coupon_code=' . urlencode($order_summary['coupon_code']) .
    or use an image pixel instead, by adding it to your tpl_footer.php:
    if ($current_page_base == 'checkout_success') {
        echo '<img border="0" src="http://www.yoursite.com/idevaffiliate/sale.php?profile=1&idev_saleamt=' . $order_summary['commissionable_order'] . '&idev_ordernum=' . $order_summary['order_number'] . '&coupon_code=' . $order_summary['coupon_code'] . '&products_purchased=' . $order_summary['products_ordered_ids'] . '" height="1" width="1">';
    No need to edit any core Zen Cart files.
    Simply create a new file: /includes/modules/pages/checkout_success/jscript_jam.php ... be sure to set the correct URL for your JAM system:
       echo '<script type="text/javascript"  src="http://www.yourdomain.com/affiliates/sale.php?amount=' . $order_summary['commissionable_order'] . '&trans_id=' . $order_summary['order_number'] . '"></script>';

    Adding product IDs or Model Numbers on older versions:
    Add the following extra code before the tracking pixel/script code above if you want to have product ID or Model data available:
    if (!isset($order_summary['products_ordered_models'])) {
      $products_array = array();
      $products_query = "SELECT products_id, products_model
                         FROM " . TABLE_ORDERS_PRODUCTS . "
                         WHERE orders_id = :ordersID
                         ORDER BY products_id";
      $products_query = $db->bindVars($products_query, ':ordersID', $orders_id, 'integer');
      $products = $db->Execute($products_query);
      while (!$products->EOF) {
        $products_array[urlencode($products->fields['products_id'])] = urlencode($products->fields['products_model']);
      $order_summary['products_ordered_ids'] = implode('|', array_keys($products_array));
      $order_summary['products_ordered_models'] = implode('|', array_values($products_array));
    Advanced Use
    Advanced programmers might choose programmatic hooks instead of javascript callbacks, by invoking the notifier system. This involves hooking NOTIFY_CHECKOUT_PROCESS_HANDLE_AFFILIATES and referencing the $_SESSION['order_summary'] array in place of the non-global $order_summary array.
    This could allow a bespoke tracking service to be invoked without needing to force extra activities down to the customer's browser.
