Shopzilla Tracking Code Placement?

[Andy_GS]

Hey all,

right im trying to add our shopzilla tracking code to the checkout success page,

proposed code:

<?php
$cn_orders = "SELECT count( orders_id ) FROM orders WHERE customers_id = '$customer_id'";
$cn_orders_result = $db->Execute($cn_orders);
if $cn_orders_result <= '1'{
$cn_orders_final = '1';
}
else{
$cn_orders_final = '0';
}
?>
<script language="javascript">
<!--
    /* Performance Tracking Data */
    var mid            = '000000';
    var cust_type      = '<?php echo $cn_orders_final ?>';
    var order_value    = '<?php echo round($orders->fields['order_total'], 2); ?>';
    var order_id       = '<?php echo (int)$orders->fields['orders_id']; ?>';
    var units_ordered  = '<?php echo sizeof($order->products); ?>';
//-->
</script>
<script language="javascript" src="https://www.shopzilla.com/css/roi_tracker.js"></script>

I know 'mid' 'order_value' and 'order_id' i know all work as i've tested this.

I'm just trying to sort these last two fields and need a little bit of help.

I need 'cust_type' to display either a '0' or a '1' depending on if they have ordered before. So as i see it the above code should display a 0 if they have ordered 1 time or more, or a 1 if they have never ordered before.

for 'units_ordered' i saw on another post (http://www.zen-cart.com/forum/showth...e+number+items) that this piece of code should work for displaying number of items:

<?php echo sizeof($order->products); ?>

i basically just want to know if im right about these two things or if the extra bit of php code i added to find number of times the person has ordered is already present on the checkout screen before i implement this.

regards

Andy.
