typecho做博客还是很好用的，为了seo，需要获取相关文章，如下：

1. Archive.php 里面有函数：默认按标签获取相关

   //type支持传author和不传，不传代表按标签推荐相关

    public function related($limit = 5, $type = NULL)
    {
        $type = strtolower($type);
    
        switch ($type) {
            case 'author':
                /** 如果访问权限被设置为禁止,则tag会被置为空 */
                return $this->widget('Widget_Contents_Related_Author',
                array('cid' => $this->cid, 'type' => $this->type, 'author' => $this->author->uid, 'limit' => $limit));
            default:
                /** 如果访问权限被设置为禁止,则tag会被置为空 */
                return $this->widget('Widget_Contents_Related',
                array('cid' => $this->cid, 'type' => $this->type, 'tags' => $this->tags, 'limit' => $limit));
        }
    }
   

2.所以代码如下

<?php $this->related(5)->to($relatedPosts); ?>
    <ul>
        <?php while ($relatedPosts->next()): ?>
        <li><a href="<?php $relatedPosts->permalink(); ?>" title="<?php $relatedPosts->title(); ?>"><?php $relatedPosts->title(); ?></a></li>
        <?php endwhile; ?>
    </ul>
