shop:onExtendOrderItemForm event

The shop:onExtendOrderItemForm event allows to add new fields to the Create/Edit Order Item form in the Administration Area. This even usually used with the shop:onExtendOrderItemModel event. The event handler should accept a single parameter - the order item object (Shop_OrderItem class). Example: 

public function subscribeEvents()
{
  Backend::$events->addEvent('shop:onExtendOrderItemModel', $this, 'extend_order_item_model');
  Backend::$events->addEvent('shop:onExtendOrderItemForm', $this, 'extend_order_item_form');
}
 
public function extend_order_item_model($order_item)
{
  $order_item->define_column('x_subscription_start_date', 'Start date')->invisible();
  $order_item->define_column('x_subscription_end_date', 'End date')->invisible();
}

public function extend_order_item_form($order_item)
{
  $order_item->add_form_field('x_subscription_start_date', 'left')->tab('Subscription');
  $order_item->add_form_field('x_subscription_end_date', 'right')->tab('Subscription');
}
