How to get post_id from order_id in woocommerce

Question

I need to get post_id in wordpress from woocommerce order id or order number.

global $woocommerce, $post;

$order = new WC_Order($post->ID);

//to escape # from order id 

$order_id = trim(str_replace('#', '', $order->get_order_number()));

with this code i am getting order id from post id. I have to reverse this and get post id from order id.

Answer 1

you do realize that an order may contain 1 or more post id right?

$order = new WC_Order( $order_id );
$items = $order->get_items();

foreach ( $items as $item ) {
    //$product_name = $item['name'];
    //$product_id = $item['product_id']; // post id
    //$product_variation_id = $item['variation_id'];
}

Answer 2

你试过这个吗？

$post_id = get_post($order_id)->ID;
