CustomOrdersTableController{}WC 1.0

This is the main class that controls the custom orders tables feature. Its responsibilities are:

  • Allowing to enable and disable the feature while it's in development (show_feature method)
  • Displaying UI components (entries in the tools page and in settings)
  • Providing the proper data store for orders via 'woocommerce_order_data_store' hook

...and in general, any functionality that doesn't imply database access.

Хуков нет.
