显示最近更新的文章或页面

<?php$today = current_time('mysql', 1);$howMany = 5; //你要显示的文章数目
if ( $recentposts = $wpdb->get_results("SELECT ID, post_title FROM $wpdb->posts WHERE post_status = 'publish' AND post_modified_gmt < '$today' ORDER BY post_modified_gmt DESC LIMIT $howMany")):?><h2><?php _e("Recent Updates"); ?></h2><ul><?phpforeach ($recentposts as $post) {if ($post->post_title == '') $post->post_title = sprintf(__('Post #%s'), $post->ID);echo "<li><a href='".get_permalink($post->ID)."'>";the_title();echo '</a></li>';}?></ul><?php endif; ?>

显示评论最多文章

<?php $result = $wpdb->get_results("SELECT comment_count,ID,post_title FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , 10");foreach ($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); ?>" title="<?php echo $title ?>"><?php echo $title ?></a></li><?php } } ?>
