Extending DataWriter_Discussion

[mlx]

I'm trying to plug some code into DataWriter_Discussion::_updateUserMessageCount

And for some reason I cannot get this to work. It's in the middle of the night so chances are I'm just doing something wrong.

For simple testing reasons this is the code:

ThreadCount\Listener\Discussion.php

<?php

class ThreadCount_Listener_Discussion
{
	public static function loadClassController($class, &$extend)
	{
		if ($class == 'XenForo_DataWriter_Discussion')
		{
			$extend[] = 'ThreadCount_DataWriter_Discussion';
		}
	}
}

ThreadCount\DataWriter\Discussion.php

<?php

class ThreadCount_DataWriter_Discussion extends XFCP_ThreadCount_DataWriter_Discussion
{
	protected function _updateUserMessageCount(array $messages, $isDelete = false)
	{
		echo "test1";
		exit;
	}
}

Listen to Event: load_class_datawriter
Execute Callback: ThreadCount_Listener_Discussion::loadClassController

It's not working. Looks like it's not called at all. Even though callback is active.

Any idea what's wrong there?

Have you verified that loadClassController() is firing?

Aah, got it. You are checking for XenForo_DataWriter_Discussion being instantiated. There's a teensy weensy problem with that:

abstract class XenForo_DataWriter_Discussion extends XenForo_DataWriter

{

XenForo_DataWriter_Discussion is an abstract class and can not be instantiated.

I suspect that the DataWriter you really want is XenForo_DataWriter_Discussion_Thread.

Oh boy. I guess OOP is still confusing me from time to time. Thanks a lot Kier!
