wp/wordpress 用户中心，调用用户的所有评论

wp主题开发用户中心页面是，很多朋友，想在一个列表调用用户的所有评论列表，怎么弄呢？废话不多哔哔，直接上代码：

<?php
global $wpdb;
$sql = "SELECT DISTINCT ID, post_title, post_password, comment_ID,comment_post_ID, comment_author, comment_date_gmt, comment_approved,comment_type,comment_author_url,SUBSTRING(comment_content,1,30) AS com_excerpt
FROM $wpdb->comments
LEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID = $wpdb->posts.ID)
WHERE  comment_approved = '1' AND comment_type = '' AND post_password = '' AND comment_author = '$current_user->display_name'
ORDER BY comment_date_gmt DESC   LIMIT 5";
$comments = $wpdb->get_results($sql);
$output = $pre_HTML;
foreach ($comments as $comment) {
  $output .= "<li><p>".strip_tags($comment->comment_author)."说：" ."<a class=\" jccsf2\" href=\"". get_permalink($comment->ID) ."#comment-" . $comment->comment_ID . "\" title=\"留言在 " .$comment->post_title . "\">" . strip_tags($comment->com_excerpt)."</a>
  </p></li>";
}
$output .= $post_HTML;
echo $output;?>

样式自行修改吧！
