OpenCart 2

A free shopping cart system. OpenCart is an open source PHP-based online e-commerce solution.

This is integration method for open source shopping cart OpenCart. The integration is done by integrating files of thank you page.

You can track per product orders, lifetime commissions and also coupons.

Edit confirm action

Navigate to your cart directory catalog/controller/checkout and open confirm.php for editing. Find this line:

$data['totals'] = array();

Put this code below that line:

$this->session->data['totals'] = $order_data['totals'];
$this->session->data['pap4_products'] = $data['products'];

Save these files and continue with next step.

Edit success action

Open file catalog/controller/checkout/success.php and find this line (first occurrence):

if ($this->customer->isLogged()) {

Place the following code above that line:

$data['pap4_orderid'] = $this->session->data['order_id'];
$data['pap4_totals'] = $this->session->data['totals'];
$data['pap4_products'] = $this->session->data['pap4_products'];
if ($this->customer->isLogged()) {
  $data['pap4_email'] = $this->customer->getEmail();
}
else {
  $data['pap4_email'] = $this->session->data['guest']['email'];
}
unset($this->session->data['pap4_products']);

Again, do not forget to save the changes and continue to the next integration step.

Whole cart as one transaction – Edit success view

If you want to process the whole payment as one transaction in PAP, follow this step. If you want to create one transaction for every product, continue to step 4.

Open file catalog/view/theme/default/template/common/success.tpl.

Add these lines before the last line which says ‘echo $footer;‘:

<?php
if(isset($pap4_totals) && isset($pap4_orderid) && isset($pap4_email)) {
  $subtotal = 0;
  foreach ($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;}
  ?>
<script id="pap_x2s6df8d" src="https://URL_TO_PostAffiliatePro/scripts/trackjs.js" type="text/javascript"></script>
<script type="text/javascript">
  PostAffTracker.setAccountId('default1');
var sale = PostAffTracker.createSale();
  sale.setTotalCost('<?php echo $subtotal; ?>');
  sale.setOrderID('<?php echo $pap4_orderid; ?>');
  sale.setData1('<?php echo $pap4_email; ?>');
  PostAffTracker.register();
</script>
<?php } ?>

Save the file and your shop is integrated.

Note: The values of ‘Coupon‘ and ‘Voucher‘ are negative, that is why we are directly adding it to the subtotal value.

One transaction per product – Edit success view

This step is not necessary if you already used step 3.

Open file catalog/view/theme/default/template/common/success.tpl.

Add these lines before the last line which says ‘echo $footer;’:

<?php
if (isset($pap4_totals) && isset($pap4_orderid) && isset($pap4_email)) {
?>
<script id="pap_x2s6df8d" src="https://URL_TO_PostAffiliatePro/scripts/trackjs.js" type="text/javascript"></script>
<script type="text/javascript">

  <?php
    $i = 0;
    foreach ($pap4_products as $item) {
      echo "var sale$i = PostAffTracker.createSale();";
      echo "sale".$i.".setTotalCost('".$item['total']."');";
      echo "sale".$i.".setProductID('".$item['product_id']."');";
      echo "sale".$i.".setOrderID('".$pap4_orderid."(".$i.")');";
      echo "sale".$i.".setData1('".$pap4_email."');";
      $i++;
    }
  ?>
  PostAffTracker.register();
</script>
<?php
}
?>

This will register a commission per each ordered product.

Do not forget to integrate your cart with the click tracking to make the sale tracking work. You can place the click tracking code to the theme footer file:
catalog/view/theme/YOUR_THEME/template/common/footer.tpl
