Who Has Posted Display Help

[grey_goose]

I'd like to have threads display a list at the top of who has currently posted in the thread. I know this information is accessible through "misc.php?do=whoposted&t=xxx" but I think that adding it to showthread would make it more accessible.

In WHOPOSTED, there is a {vb:raw posters}. I copied the code from misc.php for this section and created a plugin at showthread_getinfo, but when I add {vb:raw posters} to SHOWTHREAD, nothing appears.

Ideas?

Plugin:

PHP Code:

if (!$threadinfo['threadid'] OR $threadinfo['isdeleted'] OR (!$threadinfo['visible'] AND !can_moderate($threadinfo['forumid'], 'canmoderateposts')))
    {
        eval(standard_error(fetch_error('invalidid', $vbphrase['thread'], $vbulletin->options['contactuslink'])));
    }

    ($hook = vBulletinHook::fetch_hook('misc_whoposted_start')) ? eval($hook) : false;

    $posts = $db->query_read_slave("
        SELECT COUNT(postid) AS posts,
            post.username AS postuser,user.userid,user.username
        FROM " . TABLE_PREFIX . "post AS post
        LEFT JOIN " . TABLE_PREFIX . "user AS user USING(userid)
        WHERE threadid = $threadinfo[threadid]
            AND visible = 1
        GROUP BY userid
        ORDER BY posts DESC
    ");

    $totalposts = 0;
    $posters = '';
    if ($db->num_rows($posts))
    {
        require_once(DIR . '/includes/functions_bigthree.php');
        while ($post = $db->fetch_array($posts))
        {
            // hide users in Coventry
            $ast = '';
            if (in_coventry($post['userid']) AND !can_moderate($threadinfo['forumid']))
            {
                continue;
            }

            exec_switch_bg();
            if ($post['username'] == '')
            {
                $post['username'] = $post['postuser'];
            }
            $post['username'] .=  $ast;
            $totalposts += $post['posts'];
            $post['posts'] = vb_number_format($post['posts']);
            $show['memberlink'] = iif ($post['userid'], true, false);
            $templater = vB_Template::create('whopostedbit');
                $templater->register('bgclass', $bgclass);
                $templater->register('post', $post);
                $templater->register('threadinfo', $threadinfo);
            $posters .= $templater->render();
        }
        $totalposts = vb_number_format($totalposts);

        ($hook = vBulletinHook::fetch_hook('misc_whoposted_complete')) ? eval($hook) : false;
        
            $templater->register_page_templates();
            $templater->register('posters', $posters);
            $templater->register('threadinfo', $threadinfo);
            $templater->register('totalposts', $totalposts);
    }
