秋子淡无痕

无插件调用最新文章的例表(20代表要调用的文章数)

1. <?php wp_get_archives('type=postbypost&limit=20'); ?>

复制代码

最新评论的调用，把下面语句加入到functions.php文件的 ? > 之前

1. function get_new_comment_list() {
   
2. global $wpdb;
   
3. $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 = '' ORDER BY comment_date_gmt DESC LIMIT 10";
   
4. $comments = $wpdb->get_results($sql);
   
5. $output = $pre_HTML;
   
6. $output .= "\n<ul class="sidelist">";
   
7. foreach ($comments as $comment) {
   
8. $output .= "\n<li>". "<a href="" . get_permalink($comment->ID) . "#comment-" . $comment->comment_ID . "" title="发表于《".
   
9. $comment->post_title . "》">" . strip_tags($comment->com_excerpt) ."</a></li>";}
   
10. $output .= "\n</ul>";
    
11. $output .= $post_HTML;
    
12. echo $output;
    
13. }

显示指定分类的描述(1代表分类ID为1)

1. <?php echo category_description(1); ?>

复制代码

按分类显示每个分类的最新文章，代码如下：（其中的1,3,4,5,6,7是你要显示的分类ID号）

1. <?php $display_categories = array(1,3,4,5,6,7); foreach ($display_categories as $category) { ?>
   
2. <div class="postlist">
   
3. <?php query_posts("showposts=5&cat=$category"); $wp_query->is_category = false; $wp_query->is_archive = false; $wp_query->is_home = true; ?>
   
4. <h3 class="posttitle"><span class="more"><a href="<?php echo get_category_link($category);?>">&#187; 查看更多</a></span><?php single_cat_title(); ?></h3>
   
5. <ul>
   
6. <?php if (have_posts()) : ?>
   
7. <?php while (have_posts()) : the_post(); ?>
   
8. <li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
   
9. <?php endwhile; ?>
   
10. <?php else : ?><p class="center">此分类暂无内容</p>
    
11. <?php endif; ?>
    
12. </ul>
    
13. </div>
    
14. <?php } ?>
