I need to be able to get order_item_id, the unique value applied to each item in each order. This is what I have so far:
global $wpdb;
$order = new WC_Order( $order_id );
$items = $order->get_items();
foreach ( $items as $item ) {
$product_id = $item['product_id'];
$item_id = $item['item_id'];
The last line in the above code gets order_item_id. It normally wouldn't work but it works because I've edited get_items in class-wc-order and included:
$items[ $item->order_item_id ]['item_id'] = $item->order_item_id;
What I want to know is how can I get order_item_id without having to edit class-wc-order. Is there any easy way?
Thanks!
