WordPress：列出没有评论的帖子

Question

I have simple page that I want to display a list of posts that haven't been commented on yet. How would I do this? I presume it's some parameters I can add to the query_posts? Thanks.

Unfortunately query_posts does not allow you to limit the query to comment_count=0. You can do this:

query_posts( 'orderby=comment_count&order=ASC' );

But that does not only display posts with zero comments, it just displays those with zero comments first.

The more involved (but better) solution is to use a custom query that specifically limits the query to posts with 0 comments, but that means you would have to create your own loop structure (at least so far as I can tell)

global $wpdb;
$query = "
  SELECT *
  FROM {$wpdb->prefix}posts
  WHERE
  {$wpdb->prefix}posts.post_type = 'post'
  AND {$wpdb->prefix}posts.post_status = 'publish'
  AND {$wpdb->prefix}posts.comment_count = 0
  ORDER BY {$wpdb->prefix}posts.post_date
  DESC;
";

$pageposts = $wpdb->get_results($query, OBJECT);

 <?php if ($pageposts): ?>
 <?php global $post; ?>
 <?php foreach ($pageposts as $post): ?>
 <?php setup_postdata($post); ?>

 <div class="post" id="post-<?php the_ID(); ?>">
 <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">
    <?php the_title(); ?></a></h2>
    <small><?php the_time('F jS, Y') ?> <!-- by <?php the_author() ?> --></small>
    <div class="entry">
       <?php the_content('Read the rest of this entry »'); ?>
    </div>
    <p class="postmetadata">Posted in <?php the_category(', ') ?> | <?php edit_post_link('Edit', '', ' | '); ?>  
    <?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p>
 </div>
 <?php endforeach; ?>
 <?php else : ?>
    <h2 class="center">Not Found</h2>
    <p class="center">Sorry, but you are looking for something that isn't here.</p>
    <?php include (TEMPLATEPATH . "/searchform.php"); ?>
 <?php endif; ?>

Does that seem within your knowledge to implement?
