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?
