My intent is to track conversions through multiple channels by inserting
third party javascript (for example google analytics, optimizely, pricegrabber etc.) into
the footer of onepage success .
I've accomplished this by adding a block to
the footer reference inside of
the checkout success node within local.xml and everything works appropriately.
My questions are more about efficiency and extensibility.
It occurred to me that it would be better to combine all of
the blocks into a single block reference and then use a various methods acting on a single call to
the various related models to provide
the data needed for insertion into
the javascript for each of
the conversion tracking scripts.
Some examples of
the common data that conversion tracking may rely on(pseudo):
Order ID , Order Total, Order.LineItem.Name(foreach) and so on
Currently for each of
the scripts I've made a call to
the appropriate model passing
the customers last order id as
the load value and
the calling a get() assigning
the return value to a variable and then iterating through
the data to match
the values with
the expectations of
the given
third party service.
All of
the data should be pulled once when checkout is complete
each
third party services may expect different data in different formats
Here is an example of one of
the conversion tracking template files which loads at
the footer of checkout success.
$order = Mage::getModel('sales/order')->loadByIncrementId(Mage::getSingleton('checkout/session')->getLastRealOrderId());
$amount = number_format($order->getGrandTotal(),2);
$customer = Mage::helper('customer')->getCustomer()->getData();
?>
<script type="text/javascript">
popup_email = '<?php echo($customer['email']);?>';
popup_order_number = '<?php echo $this->getOrderId() ?>';
</script>

<!-- End PriceGrabber Code -->
Having just a single piece of code like this is not that big of a deal, but we are doing similar things with a number of different
third party services.
Pricegrabber is one of
the simpler examples.
A more sophisticated tracking service expects a comma separated list of all of
the product names, ids, prices, categories , order id etc.
I would like to make it all more manageable so my idea to do
the following:
combine all of
the template files into a single file
Develop a helper class or library to deliver
the data to
the conversion template
Goals Include
Extensibility
Minimal Model Calls
Minimal Method Calls
The Questions
1. Is a Mage helper
the best route to take?
2. Is there any design pattern you may recommend for
the "helper" class?
3. Why would this
the design pattern you've chosen be best for this instance?
