Custom data fields in newsletters
12 July 2008 at 3:55am Last edited: 12 July 2008 4:26am
Is it possible to extend the NewsLetterType class to allow a few custom data fields in the CMS when editing the newsletter? I need a nice, user-friendly way to upload a few images of a product and then reference those images in the template file.
A few custom text fields would be nice too. Is this possible with Silverstripe? If so, how can I do this?

You would want to subclass the Newsletter class
In MyNewsletter.php
class MyNewsletter extends Newsletter {
... overload getCMSFields ...
... add $db information ....
}In _config.php
Object::useCustomClass('Newsletter', 'MyNewsletter')
You will also need to make a hack to core, since it's not set up for this currently: in NewsletterEmailProcess.php, in the next function, find this code:
$e->populateTemplate(array(
'Member' => $member,
'FirstName' => $member->FirstName,
'NameForEmail'=> $nameForEmail
));And change it to this:
$e->populateTemplate(array(
'Newsletter' => $this->newsletter,
'Member' => $member,
'FirstName' => $member->FirstName,
'NameForEmail'=> $nameForEmail
));Then, in your Newsletter template file, you can reference
$Newsletter.MyVar, etc

Thanks, I'll give this a try! Will SilverStripe incorporate this functionality better in the future?
Edit: Also, I think your instructions to subclass Newsletter are reversed
Should it be:
class MyNewsletter extends Newsletter {
Instead of:
class Newsletter extends MyNewsletter {

Yes, thanks for picking up on the typo - I've corrected my original post to minimise confusion.
