以下代码将根据客户帐单/发货城市向新订单管理通知添加其他收件人：

add_filter( \'woocommerce_email_recipient_new_order\', \'different_email_recipients\', 10, 2 );
function different_email_recipients( $recipient, $order ) {
    if ( ! is_a( $order, \'WC_Order\' ) ) 
        return $recipient;

    $city = $order->get_shipping_city();
    $city = empty( $city ) ? $order->get_billing_city() : $city;

    // Conditionaly send additional email based on customer city
    if ( \'Indore\' == $city ) 
    {
        $recipient .= \',[email protected]\';
    } 
    elseif ( \'bhopal\' == $city ) 
    {
        $recipient .= \',[email protected]\';
    }

    return $recipient;
}
