silverstripe DataExtensions Adding methods to a DataObject
Example
You can add public methods to a DataObject using the extension mechanism, for example:
class MyMemberExtension extends DataExtension
{
public function getHashId()
{
return sha1($this->owner->ID);
}
}
When applied to the Member class, the example above would return the sha1 hash of the Member ID by accessing the Member via the protected property $this->owner. Eg:
$member = Member::get()->byId(123);
var_dump($member->getHashId()); // string(40) "40bd001563085fc35165329ea1ff5c5ecbdbbeef"
