There are two things to first understand about transactional emails:
- By default the templates are in
app/locale/en_US/template/email
where en_US is the locale code configured for the store.
- They can be loaded into the database and edited using an editor within the browser. If an override is done that way, they are no longer loaded from the filesystem.
So first decide, if you want to keep them loading from the file system (and thus be able to version them) or from the database (so the merchant can easily edit the layout).
The footer and header are special:
The template is configured via the system configuration System > Configuration > [General:Design] > Transactional Emails
. By default it's set to "Default from locale" which refers to the file app/locale/en_US/template/email/html/footer.html
.
To change the footer, you need to add a new template that is then stored in the database. Go to System > Transactional Emails
. You'll get a screen that has a top section to load an already defined template as base and it's probably wise to load the default:
However, Magento assumes that there's a shared footer (and shared header) for all emails, so while you can change it, you cannot change it per email.
So, in this case, your best bet is to change the order_new.html
template in app/code/locale/en_US/template/email/sales
. Remove the {{template config_path="design/email/footer"}}
and replace it with the HTML you want. This is the easiest way to override a footer for a specific template.
