Need a more specific method for counting cart quantity. Combinations & Customizations

[heliumdream]

$quantity += $product['cart_quantity'];

I'm updating some code for a client, related to an Order Fee module that has been extended to handle fee quantities. 

Counting the cart quantity of each product isn't quite what we're after. 

 

I need a solution for counting the total number of products instances - accounting for multiple combinations and any instances of those combinations that might have customization attached. 

 

I tried a number of methods, and won't include any of my botched attempts. I also looked at the order controller php and shopping cart tpl logic and architecture for clues, and still couldn't quite get it. 

 

Attached is a screenshot, just to perfectly illustrate our needs.

We would like this particular cart to reflect 4 fees. One fee per customization instance. 

In the screenshot I incremented the counter using a foreach statement to step thru a value found with getProductCustomization. I had limited success counting the number of customizations, but couldn't account for multiple combinations properly. 

Hopefully someone can illuminate the situation. Thank you.

$customization = $context->cart->getProductCustomization($product_key)

more or less i already had what was needed.

iterating thru each product, multiple combinations would cause the customization count to trigger more than once...so i added a catch to stop things if the loop already ran on a particular product_id.
