Adding Post to thread via API

[vrinteractive]

I've integrated a function of our website with vbulletin via the API to create a post in a thread on our forum.

I've got this working with ONE problem: the thread statistics aren't being updated!

The post is added to the thread. The post is visible in the thread. However, on the forum page that lists the thread, the "Last Post" column is not updated correctly. The "Replies" column is not updated either.

Here's the code I'm using. What am I missing?

PHP Code:

<?
require_once('./global.php');
require_once('./includes/class_dm.php');
require_once('./includes/class_dm_threadpost.php');

$postdm = new vB_DataManager_Post($vbulletin, ERRTYPE_STANDARD);

$postthreadid = $_REQUEST['threadid'];
$postuserid =  $_REQUEST['postuserid'];
$postpagetext = $_REQUEST['postbody'];

$postdm->set('threadid', $postthreadid);
$postdm->set('userid', $postuserid);
$postdm->set('pagetext', $postpagetext);
$postdm->set('allowsmilie', 1);
$postdm->set('visible', 1);
$postdm->set('dateline', TIMENOW);
$postdm->save();
unset($postdm);  
?>

FYI - If anyone else runs into this. Seems I missed a few lines of code:

PHP Code:

$threadinfo = fetch_threadinfo($postthreadid);
$foruminfo = fetch_foruminfo($threadinfo['forumid']);

$postdm->set_info('forum', $foruminfo);
$postdm->set_info('thread', $threadinfo);
