Вывод самых обсуждаемых тем блога

В соседней теме у меня был вапрос о самых обсуждаемых постах блога… По рекомендации я нашёл эти коды…

<?php
$days = 7; //To fetch posts published during the last 7 days
$today = date("Y-m-d H:i:s"); //Today's date
$daysago = date("Y-m-d H:i:s",strtotime(date('Y-m-j H:i:s')) - (7 * 24 * 60 * 60));  //Today - $days

$result = $wpdb->get_results("SELECT comment_count,ID,post_title, post_date FROM $wpdb->posts WHERE post_date BETWEEN $daysago AND $today ORDER BY comment_count DESC LIMIT 0 , 10");

foreach ($result as $topten) {
    $postid = $topten->ID;
    $title = $topten->post_title;
    $commentcount = $topten->comment_count;
    if ($commentcount != 0) {
    ?>
         <li><a href="<?php echo get_permalink($postid); ?>"><?php echo $title ?></a></li>
    <?php }
}
?>

<h2>Most commented posts from 2008</h2>
<ul>
<?php
$result = $wpdb->get_results("SELECT comment_count,ID,post_title, post_date FROM $wpdb->posts WHERE post_date BETWEEN '2008-01-01' AND '2008-12-31' ORDER BY comment_count DESC LIMIT 0 , 10");

foreach ($result as $topten) {
    $postid = $topten->ID;
    $title = $topten->post_title;
    $commentcount = $topten->comment_count;
    if ($commentcount != 0) {
    ?>
         <li><a href="<?php echo get_permalink($postid); ?>"><?php echo $title ?></a></li>
    <?php }
}
?>
</ul>

Но вот проблема! – Они не работают….:(
