Frontend usage

Admin usage

• Displays against possible shipments
• Prints onto shipment labels
• Can be added to a customer address by an admin user without autosuggest plugin
• Despite the lack of plugin, the above will still run through the same validation as the frontend

Technical and data storage

• Stores to 3 tables throughout a w3w lifecycle - quote, order and customer.
• Saves to w3w_sales_quote from shipping address form via a JS mixin and AJAX call
• Saves to w3w_sales_order from order placement via an Observer
• Saves to w3w_customer_address from the above two, from the customer account area and from the admin
• A customer address attribute is required to edit this value from the admin; this is populated with a plugin in the above areas.

Implementation

• Field is added to checkout with a LayoutProcessorPlugin linked to a JS component, shipping.js.
• Field is added to customer form using an HTML script tag, appended with jQuery. This is linked to a JS component, customer/edit.js.
• Custom jQuery validation system is used to handle AJAX results.
• The SaveToVarchar plugin handles saving the address attribute.
• The AddressRendererPlugin handles displaying the saved 3 word address against addresses on orders.
