Display Product detail and Discount variable in any email template

[Jolsvi]

Hi, I'm currently using Prestashop 1.6.1.4 and having problem to display order summary in the email template for customer.

In this case I want to send 'bankwire' template with order summary. At the moment I can display variable : {carrier}, {payment}, {order_name}, {total_products} etc..

But the variable {products} and {discounts} are not working.

Is there anyone has solved this issue? Help me please

 

Thanks

 

Note: I applied the override OrderHistory.php from this link:
