OrdersTableDataStore::get_diff_meta_data_between_orders() │ private │ WC 1.0

Helper function to compute diff between metadata of post and cot data for an order.

Also provides an option to sync the metadata as well, since we are already computing the diff.

Method of the class: OrdersTableDataStore{}

No Hooks.

Return

Array. Difference between post and COT meta data.

Usage

// private - for code of main (parent) class only
$result = $this->get_diff_meta_data_between_orders( $order1, $order2, $sync ): array;
$order1(\WC_Abstract_Order) (required)
Order object read from posts.
$order2(\WC_Abstract_Order) (required)
Order object read from COT.
$sync(true|false)
Whether to also sync the meta data.
Default: false
