I've seen a bunch of articles (mostly 3-5 years old) detailing various methods of getting the customer's first name into the order confirmation email but I just get either a blank, or unparsed PHP.
For example this:
<?php echo $this->__('Hello, %s', Mage::getSingleton('customer/session')->getCustomer()->getFirstname()); ?>
Renders in the email like this:
__('Hello, %s', Mage::getSingleton('customer/session')->getCustomer()->getFirstname()); ?>
Could somebody point me in the right direction? This is on Community Edition 1.7.
Thanks
