Hello
I am at the same point, I changed the e-mail template, adding the following:
$shippingClass = hikashop_get('class.shipping');
$shipping = $shippingClass->get($data->order_shipping_id);
$shipping->shipping_params = unserialize($shipping->shipping_params);
echo $shipping->shipping_name;
-> That works fine, shipping method is included
$paymentClass = hikashop_get('class.payment');
$payment = $paymentClass->get($data->order_payment_id);
$payment->payment_params = unserialize($payment->payment_params);
echo $payment->payment_params->information;
->That works too, but only if the payment method is "banktransfer"
How can I include other pament methods (e.g. Paypal, collect on delivery)?
