While the trackProduct() function works fine, the JS for the checkout_complete is not being added to the thank you page:

CoreShop/src/CoreShop/Bundle/TrackingBundle/Tracker/Google/TagManager/TagManagerEnhancedEcommerce.php

Line 180 in bab33c0

$this->codeTracker->addCodePart($result);

Others like trackCheckoutStep are working too.

@Cruiser13 I just tested it - it works on my side:

But it does not send any event property.

Google also does not propose an event property in purchase section:

To-Do Summary:

Tracking Issues

trackCheckoutComplete

• Rename total to revenue

trackProduct

• remove quantity attribute

trackProductImpression

• remove quantity attribute
• submit impression as multi- instead of single-array

trackCartAdd

• price attribute: I'm not sure about that but I think we need to use the cart item price instead of product price (which often can't be determinate (because of complex variant structure etc.)
• quantity is hardcoded to 1. Use $quantity instead?

trackCartRemove

• This event never gets tracked because after the tracker is called an instant redirectResponse gets executed. We need to add the tracker blocks to a flash bag for example and call it later in summaryAction.

My Workaround:

<?php

namespace AppBundle\Controller;

class CartController extends \CoreShop\Bundle\FrontendBundle\Controller\CartController
{
    public function summaryAction(Request $request)
    {
        // @todo: remove this method after #1613 has been fixed
        // @see: https://github.com/coreshop/CoreShop/issues/1613

        $flashBag = $this->container->get('session')->getFlashBag();
        $codeTracker = $this->get(CodeTracker::class);

        if ($flashBag instanceof FlashBag && $flashBag->has('_tracking')) {
            foreach ($flashBag->get('_tracking') as $bag) {
                if (is_array($bag)) {
                    foreach ($bag as $block) {
                        $codeTracker->addCodePart($block);
                    }
                }
            }
        }

        return parent::summaryAction($request);
    }

    public function removeItemAction(Request $request)
    {
        // @todo: remove this method after #1613 has been fixed
        // @see: https://github.com/coreshop/CoreShop/issues/1613

        $cartItem = $this->get('coreshop.repository.cart_item')->find($request->get('cartItem'));

        if ($cartItem instanceof CartItemInterface) {

            $this->get('coreshop.tracking.manager')->trackCartRemove(
                $this->getCart(),
                $cartItem->getProduct(),
                $cartItem->getQuantity()
            );

            $blocks = $this->get(CodeTracker::class)->getBlocks();

            if (is_array($blocks) && count($blocks) > 0) {
                $this->addFlash('_tracking', $blocks);
            }
        }

        return parent::removeItemAction($request);
    }
}

@solverat thank you for your reply! If it works for you I have to look deeper in our installation. Might be dependent on the payment method, some payment providers have weird redirections.

[solverat]

The checkout_complete is defined in thankYouAction:

CoreShop/src/CoreShop/Bundle/FrontendBundle/Controller/CheckoutController.php

Line 329 in bab33c0

$this->get(TrackerInterface::class)->trackCheckoutComplete($order);

I might be wrong, but every checkout process - regardless which payment provider is involved - should end there.

[Cruiser13]

I'll check that, thanks!
One thing I directly noted from your code - you do have "total" in the dataLayer while Google does expect "revenue" by default according to the docs. Might be an issue later - if I get the dataLayer filled at all.

@Cruiser13 I've added the total <> revenue to the to-do list: #1613 (comment)
