We are looking to add item information into the sales confirmation template. Pretty sure that this is the handle that pulls in the products that were ordered. However, we are looking to pull data from field "Production Time". Many of our products have varied production times so if someone orders from products that had different times, we would like that info listed on the email template under each product. Is this possible?
you can do below way
'value' => 'Additional Options Value'
you need to get value from the product and add to there.
So it will solve all the problem. so it will store data into the quote, order and another page where you want.
@giovanni_falco you can create the attribute for the product and then assign them values from admin and show them where ever you want to show.
will the solution you linked work for Magento 1.12 ?
