这段关于评论数量调用的代码问题出在哪呢？

[GASALA]

折腾wordpress，想在侧栏显示一个按有最新评论排列的文章的列表。有点类似论坛的排序方式，

代码如下，但是文章对应的评论数量调不出来...

另外，我还想把文章对应的最新评论时间也显示出来，应该怎么写呢？比如：**分钟前评论了

新人求助，谢谢哦^_^

<?php $pop = $wpdb->get_results("SELECT DISTINCT comment_post_ID FROM $wpdb->comments WHERE comment_approved = 1 AND comment_post_ID NOT IN ( SELECT ID FROM $wpdb->posts WHERE post_type != 'post' OR post_status != 'publish' OR post_password != '' ) ORDER BY comment_date_gmt DESC LIMIT 6"); ?>

<?php foreach($pop as $post) : ?>

<li class="post-thumb">

<span class="post-thumb-number"><?php wp_count_comments( $post->comment_post_ID ); ?></span>

<span class="post-thumb-image"><a href="<?php echo get_permalink($post->comment_post_ID); ?>" title="<?php echo get_the_title($post->comment_post_ID); ?>"><?php $thumbID=get_the_post_thumbnail($post->comment_post_ID,array(30,30),$imgsrcparam); ?><?php echo "$thumbID"; ?></a></span>

<span class="post-thumb-title offset"><a href="<?php echo get_permalink($post->comment_post_ID); ?>" title="<?php echo get_the_title($post->comment_post_ID); ?>"><?php echo get_the_title($post->comment_post_ID); ?></a></span>

</li>

<?php endforeach; ?>
