示例2: filter
the "comments.php" file within the "Comments Loop" with the following line.
<br/>
if(function_exists(ckrating_display_karma)) { ckrating_display_karma(); }
</p>
<p>
<b>Styling the Comment Box:</b>
The comment styling uses the new
comment_class filter (introduced in Wordpress 2.7). If your
theme doesn't use Wordpress 2.7 wp_list_comments(),
you'll only see the comment text background being styled/highlighted. To
fix the problem, you need to add comment_class into your existing
theme. For example code, please see <a
href="http://brassblogs.com/blog/wordpress-27-and-comment-display">here</a>.
