How do you script BB Code?

[Jaxel]

Hmm... Dismounted, thanks for the help... I didn't see your new post till now...

I got this working a few days ago, and this is the code I am using:

PHP Code:

if ($vbulletin->options['videodirectory_bbcode'])
{
    // [VIDEO] [VIDEO=XXX]
    $tag_list['no_option']['video'] = array(
        'callback' => 'handle_external',
        'strip_empty' => true,
        'stop_parse' => true,
        'disable_smilies' => true,
        'disable_wordwrap' => true,
        'strip_space_after' => 0,
        'external_callback' => 'handle_bbcode_video'
    );
    $tag_list['option']['video'] = array(
        'callback' => 'handle_external',
        'strip_empty' => true,
        'stop_parse' => true,
        'disable_smilies' => true,
        'disable_wordwrap' => true,
        'strip_space_after' => 0,
        'external_callback' => 'handle_bbcode_video'
    );
}

function handle_bbcode_video(&$parser, $videoid, $videotitle)
{
    global $vbulletin, $stylevar;

    if (!$video = $vbulletin->db->query_first("SELECT video.* 
        FROM " . TABLE_PREFIX . "video AS video WHERE videoid = '" . $videoid . "'"))
    {
        $video['error'] = 'THIS VIDEO DOES NOT EXIST';
        eval('$HTMLembed = "' . fetch_template('video_bbcode') . '";');
        return $HTMLembed;
    }

    require_once(DIR . '/includes/functions_videodirectory.php');
    require_once(DIR . '/includes/class_videosharingservice.php');
    require_once(DIR . '/includes/videoserviceapi/class_' . strtolower($video['videoservice']) . '.php');

    $classname = "vB_VideoSharingService_$video[videoservice]";
    $obj = new $classname($vbulletin);

    $showful = $vbulletin->options['videodirectory_showful'];
    $showrel = $vbulletin->options['videodirectory_showrel'];
    $showsta = $vbulletin->options['videodirectory_showsta'];

    $video['embed'] = $obj->fetch_embedcode($video['videoidservice'], false, $showful, $showrel, $showsta);
    $video['url'] = construct_video_url($video);
    if (empty($videotitle)) { $videotitle = $video['title']; }

    eval('$HTMLembed = "' . fetch_template('video_bbcode') . '";');
    return $HTMLembed;
} 


Do you mind looking it over so see if I am doing anything wrong? I'm doing this all in a SINGLE plugin; is that wrong?
