Custom entry in E-mails on order change

I am wanting to add another field in the dictionary called
CUSTOMMESSAGE="My custom message"

I want this message to be displayed in the email that is sent out when the order status is changed to "Confirmed"

How do I go about this?

Hi,

The simplest is to directly write your text in the order status notification email template that you can edit in the HTML version area of the email via the menu System>Emails.
And if you want to use translations, then you want to add instead such code in there:
<?php echo JText::_('CUSTOMMESSAGE'); ?>
and then add your translation line to the override area of your HikaShop translation file via the Languages tab of the HikaShop configuration.

Ok, just one more question on this part. I am only wanting this custom message to display when the Purchase status changes to "confirmed"

What would the PHP if statement look like? I have looked at the code but seem to be missing the part that deals with the status.

Hello,
The solution will be to use some php code like :
Note that you'll have to replace the "YOUR_STATUS" string by the order status.
