Mike Jolley on "[Plugin: WooCommerce] Custom product meta on order status completed"

I have a custom checkbox that I've added the product on the back end. I would like to be able to check if the value is true in the action "woocommerce_order_status_completed", but I can't seem to find a way to do so. Can someone help me out.

If my_custom_checkbox is true then do something.......

During woocommerce_order_status_completed, get the items from the order and loop over them.

$items = $order->get_items();
foreach ( $items as $item ) { $product = $order->get_product_from_item( $item );
}

With the product you can then get meta data. https://developer.wordpress.org/reference/functions/get_post_meta/
