Add Product's Manufacturer In New Order E-Mail

[JazZ7]

Hello,

 

I'd like to add the product's manufacturer name in the new order e-mail. Customer side and admin side. 

 

So, I'd tried to edit the /mails/fr/order_conf_product_list.tpl file to add a new cell with

{$product['manufacturer_name']}

but with no chance.

 

I already tried severals tips from the forum like the following but the cell stayed empty...

Any help will be appreciate.

 

Thank you very much.
