Order ID on email subject

[nahlin]

Hi,

 

I'm trying to add the order id on the email order confirmation subject that its sent to a customer.

I want the subject to be like "Subject [order id]". I've tried adding '['.$order->id.']'.

Edit: I added that to PaymentModule.php and seems to work.

 

Now I need to add it to the order statuses like "Waiting for payment" or "Payment accepted" but I have no idea of where to put it because I don't see anything related to that in the files.

 

Any ideas?
