Hyvä Checkout Magento Events
Hyvä Checkout dispatches several Magento events during the checkout lifecycle. You can observe these events in your custom modules to run code at specific points - for example, when the checkout initializes, when a step loads, or when the layout is being processed.
The hyva_checkout_init_after Event
The hyva_checkout_init_after event fires when a customer loads the Hyvä Checkout for the first time, or when the customer revisits the checkout after one of the following events has been triggered:
checkout_cart_save_aftercheckout_quote_destroycheckout_submit_all_aftercustomer_login
If you need to trigger a checkout session reset for a custom event, use the Hyva\Checkout\Observer\Frontend\HyvaCheckoutSessionReset class inside an etc/frontend/events.xml file in your module.
Checkout Init Events: hyva_checkout_{checkout_name}_init and hyva_checkout_{checkout_name}_{step_name}_init
These Hyvä Checkout init events fire when the checkout step configuration loads for the first step. If the checkout only has a single step, both events are dispatched as well.
Use these events to run code specifically on the first step of a given checkout. Replace {checkout_name} with your checkout's identifier and {step_name} with the step identifier.
Checkout Booted Events: hyva_checkout_{checkout_name}_booted and hyva_checkout_{checkout_name}_{step_name}_booted
The Hyvä Checkout booted events fire on every step when the step configuration loads. Unlike the init events (which only fire on the first step), the booted events fire each time any step loads.
Use these events to run code on every step of a specific checkout, or to target a particular checkout/step combination.
Layout Process Events: hyva_checkout_layout_process_before
The Hyvä Checkout layout process events fire when step layout directives are processed. Three variants are dispatched, ranging from general to specific:
hyva_checkout_layout_process_before_hyva_checkout- fires for all Hyvä Checkoutshyva_checkout_layout_process_before_hyva_checkout_{checkout_name}- fires for a specific checkouthyva_checkout_layout_process_before_hyva_checkout_{checkout_name}_{step_name}- fires for a specific checkout/step combination
These events let you conditionally load a layout handle for a particular checkout or step. The event payload includes a page argument containing an instance of Magento\Framework\View\Result\Page.
Step-specific layout handles
Step-specific layout handles can also be applied via checkout XML without using events.
