Click tracking code

”XXXXXXXXXXX“ needs to be substituted for your account ID    

<script type="text/javascript" id="pap_x2s6df8d" src="https://login.dognet.sk/scripts/fj27g82d"></script>
<script type="text/javascript">
PostAffTracker.setAccountId('XXXXXXXXXXX');
try {
PostAffTracker.track();
} catch (err) { }
</script>

 

Sale tracking code

”XXXXXXXXXXX“ needs to be substituted for your account ID  

<?php
if(isset($pap4_totals) && isset($pap4_orderid)) {
  $subtotal = 0;
  foreach ($pap4_totals as $item) {
    if ($item['code'] == 'sub_total') {$subtotal += $item['value'];}
    if ($item['code'] == 'coupon') {$subtotal += $item['value'];}
    if ($item['code'] == 'voucher') {$subtotal += $item['value'];}
  }
  if ($subtotal < 0) {$subtotal = 0;}
  $subtotal = $subtotal / 1.27;
  ?>
<script type="text/javascript" id="pap_x2s6df8d" src="https://login.dognet.sk/scripts/fj27g82d"></script>
<script type="text/javascript">
  PostAffTracker.setAccountId('XXXXXXXXXXX');
var sale = PostAffTracker.createSale();
  sale.setTotalCost('<?php echo ((float)$subtotal / 1.2); ?>');
  sale.setOrderID('<?php echo $pap4_orderid; ?>');
  PostAffTracker.register();
</script>
<?php } ?>

  In case you have VAT other than 20%, adjust division in the line sale.setTotalCost.
