How to check payment method on a WooCommerce order by id?

Question

I want to make some changes if the chosen payment method is COD. On existing WC_Order i have used

($order->payment_method_title == \'Cash On Delivery\' ? ...          


        

Answer 1

The post meta key for the payment method ID is simply _payment_method

So if $order->payment_method doesn't have the magic methods in place to get that automatically, you could retrieve the post meta using traditional WordPress

get_post_meta( $order->id, '_payment_method', true );

Update for WooCommerce 3.0

$order->get_payment_method();
