Add customer name to WooCommerce Admin New Order Email subject

wc-admin-new-order-email-change-subject.php

<?php // only copy this line if needed!


/**
 * Adds customer first and last name to admin new order email subject.
 *
 * @param string $subject email subject
 * @param \WC_Order $order the order object for the email
 * @return string updated subject
 */
function skyverge_add_customer_to_email_subject( $subject, $order ) {

	$subject .= ' from ' . $order->get_billing_first_name() . ' ' . $order->get_billing_last_name();

	return $subject;
}
add_filter( 'woocommerce_email_subject_new_order', 'skyverge_add_customer_to_email_subject', 10, 2 );

That is outdated. Please see revised below:

// Adds customer first and last name to admin new order email subject
function skyverge_add_customer_to_email_subject( $subject, $order ) {
	$subject = '[J.N. Equipment Superstore] New Customer Order - (# ' . $order->get_order_number() . ') from ' . $order->get_billing_first_name() . ' ' . $order->get_billing_last_name();
	return $subject;
};
add_filter( 'woocommerce_email_subject_new_order', 'skyverge_add_customer_to_email_subject', 10, 2 );

Giving quite some PHP errors / notices since WooCommerce 3.0 if you don't update it to '$order->get_...' :)

hello, same question would be important for me. the code works fine, just the product name must be added to the subject.
