Shipping method not showing in invoice

Hi,
I did some custom settings to my invoice layout and I want to show the shipping method. I the HikaMarket - ordermarket-invoice.php I found this bit of code:

if(!empty($this->shipping)){
echo JText::_('HIKASHOP_SHIPPING_METHOD').' : '.$this->shipping->getName($this->order->order_shipping_method, $this->order->order_shipping_id). '<br/>';
}

But it shows only the word shipping method (in my case 'Versandkosten') but not the carrier like DHL, Post etc.
Could you give me an idea what to add here to get that information on my invoice? I attached a pic to see where the problem is.
Thanks
Roger

Hello,
The shipping method is displayed through that code :

			<?php if(!empty($this->shipping)){
				echo JText::_('HIKASHOP_SHIPPING_METHOD').' : '.$this->shipping->getName($this->order->order_shipping_method,$this->order->order_shipping_id).'<br/>';
			}?>

Hi Mohamed,
thanks for your reply. I'm using this code, but it doesn't show the carrier.
Maybe there is a problem because I'm using HikaMarket and the shipping methods are all connected to a vendor...

Hello,
Can you give us more information about your issue like what kind of order's invoice do you want to display and where ?

Sure,
it's all in the vendors front end of HikaMarket. If you select an order, you have the option to open an invoice. This is the one I'm talking about.

Great answer Jerome!
I have no idea, if the problem is HikaMarket or HikaShop related, because the carrier doesn't show in both of them.
I'll put this threat in the HikaMarket forum too and hope to get an answer there....
