Events

The events that are currently captured are:

  • view_item_list
  • view_item
  • add_to_cart
  • remove_from_cart
  • view_cart
  • select_promotion
  • begin_checkout
  • purchase

view_item_list

This event is triggered on the Catalog Category pages and the Catalog Search Result page. In both cases the DataLayer is rendered in the backend.

Because of the Full Page Cache (FPC) it is necessary to retrieve the user_data part via AJAX before pushing it to the DataLayer global.

The block for rendering the Catalog Category Datalayer is Taggrs\DataLayer\Block\Event\CategoryViewItemList.

The block for rendering the Catalog Search Results DataLayer is Taggrs\DataLayer\Block\Event\SearchResultsViewItemList.

view_item

This event is triggered on the Catalog Product Page. This DataLayer is rendered in the backend.

Because of the FPC it is necessary to retrieve the user_data part via AJAX before pushing it to the DataLayer global.

The block for rendering the DataLayer is Taggrs\DataLayer\Block\Event\ViewItem.

add_to_cart

This event is triggered when a product is added to the cart. Because adding a product to the cart is an AJAX event in Magento 2, it is necessary to render the DataLayer via an AJAX event.

The DataLayer is rendered in the following frontend controller: Taggrs\DataLayer\Controller\AddToCart\Index.

remove_from_cart

This event is triggered when a product is removed from the cart. It can happen from the Minicart, or from the Checkout Cart page.

Minicart

Because removing a product from the cart is an AJAX event in Magento 2, it is necessary to render the DataLayer via AJAX.

Because it's impossible to retrieve information about a product that is removed from the cart, it is necessary to have the information about the cart readily available in the frontend.

This data is rendered in Taggrs\DataLayer\Controller\GetQuoteData\Index.

The DataLayer is built and pushed to the DataLayer global in Taggrs/DataLayer/view/frontend/web/js/checkout-sidebar-mixin.js.

Checkout Cart

Because there's a redirect after removing a product from the cart it's needed to render the DataLayer in the backend and store it in the session to show it in the frontend.

The DataLayer is built in Taggrs\DataLayer\Plugin\RemoveFromCart. Which is registered as a plugin for Magento\Checkout\Controller\Cart\Delete::beforeExecute().

It's then stored in the session and after the redirect it's retrieved from the session and rendered by Taggrs\DataLayer\Block\SessionDataLayer.

view_cart

This event is triggered on the Checkout Cart page. Because the checkout pages aren't cached in the FPC it's not necessary to load the user data via AJAX.

The DataLayer is rendered in Taggrs\DataLayer\Block\Event\ViewCart.

view_cart is also triggered via AJAX if the header mini cart is opened. The AJAX DataLayer is rendered in Taggrs\DataLayer\Controller\ViewCart\Index.

select_promotion

This event is triggered when a customer applies a discount code. This can be on the Checkout Cart page or on the Checkout Payment page.

Checkout Cart page

Because there's a redirect after applying a coupon, it's needed to render the DataLayer in the backend and store it in the session to show it in the frontend, just like the remove_from_cart event on the Checkout Cart page.

The DataLayer is built in Taggrs\DataLayer\Plugin\SelectPromotion.

Checkout Payment page

Because applying a coupon on the Checkout Payment page is an AJAX event, the DataLayer needs to be rendered via AJAX too.

The DataLayer is built in Taggrs\DataLayer\Controller\SelectPromotion\Index.

begin_checkout

This event is triggered on the Checkout Index page. This DataLayer is rendered in the backend in Taggrs\DataLayer\Block\Event\BeginCheckout.

add_shipping_info

This event is triggered on the Checkout Index page when a logged in customer selects his shipping address, or when a guest customer enters the postcode.

The DataLayer is rendered in Taggrs\Datalayer\Controller\AddShippingInfo\Index.

add_payment_info

This event is triggered on the Checkout Index page when a customer selects a payment method.

The DataLayer is rendered in Taggrs\Datalayer\Controller\AddPaymentInfo\Index.

purchase

This event is triggered on the Checkout Thank You page. Because in some cases customers will not see the Checkout Thank You page, it's also needed to push the DataLayer from the backend using the Google Measurements API.

Checkout Thank You page

This DataLayer is rendered in the backend using Taggrs\DataLayer\Block\Event\Purchase.
