vb.org Archive - Adding a Dropdown to a Sidebar menu PHP Code

I had a suggestion come in from a member and I want to try and make it happen.

Currently, I have 3 different side blocks

1 - Member's last 5 started threads (thinking of eliminating)

and 2 for various sections of my forum (using the block default)

what I don't want to is add numerous blocks for each of the main categories, thus I was thinking about using a dropdown (something like this???)

Code:

$form = array('--Select Forum--', 'Baseball', 'Football', 'Hockey');

$selected_key = $_POST['form];

$selected_val = $form[$_POST[form']];

and I want to tie this to the code used for the last 5 member threads started and the base for allowing for the members to see the last 5-8 posts in a given section

Code:

global $vbulletin;

global $db;



        $sqlketnoi = $vbulletin->db->query_read("

        SELECT *

        FROM " . TABLE_PREFIX . "thread

        WHERE postuserid = ".$vbulletin->userinfo['userid']."

        ORDER BY threadid DESC 

        LIMIT 5

        ");        

while($thread = $vbulletin->db->fetch_array($sqlketnoi))

{

$threadid = $thread['threadid'];

$title = $thread['title'];

$userid = $thread['postuserid'];

$username = $thread['postusername'];

$replycount = $thread['replycount'];

$dateline = date("m/d/Y",$thread['dateline']);



//forum name

        $sqlketnoi2 = $vbulletin->db->query_read("

        SELECT *

        FROM " . TABLE_PREFIX . "forum

        WHERE forumid = ".$thread['forumid']."

        ");        

        while($forum = $vbulletin->db->fetch_array($sqlketnoi2))

        {

                $forumtitle = $forum['title'];

                $forumid = $forum['forumid'];

                        

        }

        // print everything 

                $templater = vB_Template::create('block_mythread');

                $templater->register('threadid', $threadid);

                $templater->register('title', $title);

                $templater->register('userid', $userid);

                $templater->register('username', $username);

                $templater->register('replycount', $replycount);

                $templater->register('dateline', $dateline);

                $templater->register('forumid', $forumid);

                $templater->register('forumtitle', $forumtitle);        

                $content .= $templater->render();                

}

return $content;

Is something like this even possible? I know I'd have to hook the dropdown in somehow, but this is where my lack of programming knowledge hurts me.

EDIT - here is my sidebar at the moment - the first block is the last 5 threads started
