Hello

My googling has yielded no results, thus I turn to you.
I've got a Silverstripe setup with an extended Member-class and it's own database table. I now want to create an external interface for accessing data stored in said table. Since this is my first confrontation with Silverstripe I'm rather stumped as to how to achieve this.
What I've tried:

require_once("../sapphire/core/Core.php");
if(Member::currentUserID())

The function exists and can be called, but never returns anything but 0 and does not enter the if (I am logged in however).
Also, I don't want to create a subpage on the site for this. Is there any way to achieve my goal?

Thanks

Nobody got any ideas?

Well for any poor soul trying to find the same answer here: Treat it like a plugin and extend a Controller Class.

_config.php:

Director::addRules(50, array('someLink/$Action' => 'extendedControllerName'));

some File in /code:

class extendedControllerName extends Controller
{
	public static $allowed_actions = array('get');
	
	public function get() { echo "get" }
}

Calling yourURL/someLink/get will then echo "get". If not, flush=1 helps.
