在var/Widget/Contents/Post目录新建Rand.php文件，内容如下

if (!defined('__typecho_ROOT_DIR__')) exit;class Widget_Contents_Post_Rand extends Widget_Abstract_Contents { /*** 执行函数** @access public* @return void*/ public function execute() {$this->parameter->setDefault(array('pageSize' => $this->options->postsListSize));$select = $this->select();if(isset($this->request->mid)){$select->join('table.relationships', 'table.contents.cid = table.relationships.cid')->where('table.relationships.mid = ?', $this->request->mid);}$select->where('table.contents.status = ?', 'publish')->where('table.contents.created < ?', $this->options->gmtTime)->where('table.contents.type = ?', 'post')->order('', 'RAND()')->limit($this->parameter->pageSize);$this->db->fetchAll($select, array($this, 'push')); } }

使用方法

觉得迷你信息网还不错就告诉你的朋友<div><ul><?php $this->widget('Widget_Contents_Post_Rand','pageSize=5')->parse('<li><a href="{permalink}">{title}</a></li>'); ?></ul></div>

显示某个分类下的随机文章

<div><ul><?php $this->widget('Widget_Contents_Post_Rand','pageSize=5','mid=3')->parse('<li><a href="{permalink}">{title}</a></li>'); ?></ul></div>

此代码完美的解决了Single.主题，底部最新文章和归档页面的冲突问题.
