OpenCart 3

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

This is an integration method for open source shopping cart OpenCart version 3. 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 the next step.

Edit success action

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

if (isset($this->session->data['order_id'])) {

Place the following code directly below that line and above the line with $this->cart->clear();:

$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.twig.

Add these lines before the last line which says {{ footer }}:

{# Post Affiliate Pro integration #}
{% if pap4_totals is defined and pap4_orderid is defined and pap4_email is defined %}
  {% set subtotal = 0 %}

  {% for item in pap4_totals %}
    {% if item.code == 'sub_total' %} {% set subtotal = subtotal + item.value %} {% endif %}
    {% if item.code == 'coupon' %} {% set subtotal = subtotal + item.value %} {% endif %}
    {% if item.code == 'voucher' %} {% set subtotal = subtotal + item.value %} {% endif %}
  {% endfor %}

  {% if subtotal < 0 %} {% set subtotal = 0 %} {% endif %}

  <script id="pap_x2s6df8d" src="https://URL_TO_PostAffiliatePro/scripts/trackjs.js" type="text/javascript"></script>
  <script type="text/javascript">
  PostAffTracker.setAccountId('Account_ID');
  var sale = PostAffTracker.createSale();
    sale.setTotalCost('{{subtotal}}');
    sale.setOrderID('{{pap4_orderid}}');
    sale.setData1('{{pap4_email}}');
    PostAffTracker.register();
  </script>
{% endif %}
{# /Post Affiliate Pro integration #}

Save the file. Your shop has just been 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’ve already followed step 3.

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

Add these lines before the last line which says {{ footer }}:

{# Post Affiliate Pro integration #}
{% if pap4_totals is defined and pap4_orderid is defined and pap4_email is defined %}
  <script id="pap_x2s6df8d" src="https://URL_TO_PostAffiliatePro/scripts/trackjs.js" type="text/javascript"></script>
  <script type="text/javascript">
    PostAffTracker.setAccountId('Account_ID');
    {% for item in pap4_products %}
        var sale{{ loop.index }} = PostAffTracker.createSale();
        sale{{ loop.index }}.setTotalCost('{{ item.total }}');
        sale{{ loop.index }}.setProductID('{{ item.product_id }}');
        sale{{ loop.index }}.setOrderID('{{ pap4_orderid }}({{ loop.index }})');
        sale{{ loop.index }}.setData1('{{ pap4_email }}');
        {% if loop.last != false %}
        sale{{ loop.index }}.doNotDeleteCookies();
        {% endif %}
    {% endfor %}
    PostAffTracker.register();
  </script>
{% endif %}
{# /Post Affiliate Pro integration #}

This will register a commission per each ordered product.

Do not forget to integrate your cart with the click tracking code 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.twig.
