ANYONE?? PLUG IN: Jump to Your Last Post in a Thread - M1th

[yesfans]

This Plug In was from 3.6 or 3.7 I do not recall what my site was on when I added that one but it does not work in the current VB. Below is the code that was found in the showthread_getinfo HOOK LOCATION Here is the code info for it, can anyone make this work in the lastest VB ?????????

// ************************************************** ****************************** *
// goto users last post -- @M1th

if ($vbulletin->GPC['goto'] == 'lastupost')
{


$threadinfo = verify_id('thread', $threadid, 1, 1);

$uposts = $db->query_first("
SELECT MAX(postid) AS postid
FROM " . TABLE_PREFIX . "post
WHERE threadid = $threadinfo[threadid]
AND userid= " . $vbulletin->userinfo['userid'] ."
AND visible = 1
LIMIT 1
");
if ($uposts['postid'])
{
exec_header_redirect('showthread.php?' . $vbulletin->session->vars['sessionurl_js'] . "p=$uposts[postid]$highlightwords#post$uposts[postid]");
}
else
{
exec_header_redirect('showthread.php?' . $vbulletin->session->vars['sessionurl_js'] . "t=$threadinfo[threadid]&goto=lastpost$highlightwords");
}

}
