撸啊撸

把下面代码放到functions.php

class XAuthor extends Widget_Abstract_Users
{
    protected $options;

    /**
     * 构造函数,初始化组件
     *
     * @param mixed $request
     * @param mixed $response
     * @param mixed $params
     * @throws Typecho_Widget_Exception
     */
    public function __construct($request, $response, $params = NULL)
    {
        parent::__construct($request, $response, $params);
        $options = $this->widget('Widget_Options');
    }

    /**
     * 执行函数,初始化数据
     *
     * @access public
     * @return void
     */
    public function execute()
    {
        if ($this->parameter->uid) {
            $this->db->fetchRow($this->select()
                ->where('uid = ?', $this->parameter->uid), array($this, 'push'));
        }
    }

    /**
     * 获取文章总数
     *
     * @param string
     * @return void
     */
    public function ___postsNum()
    {
        $args = func_get_args();
        if (!$args) {
            $args[] = '%d';
        }

        $select = $this->db->select('count(*) as num')->from("table.contents")->where('table.contents.type = ?', 'post')->where('table.contents.status = ? OR table.contents.status = ?', 'publish', 'hidden')->where('table.contents.authorId = ?', $this->parameter->uid)->limit(1);

        $num = intval($this->db->fetchObject($select)->num);
        echo sprintf(isset($args[$num]) ? $args[$num] : array_pop($args), $num);
    }

    /**
     * 获取用户评论数
     *
     * @param string
     * @return void
     */
    public function commentsNum()
    {
        $args = func_get_args();
        if (!$args) {
            $args[] = '%d';
        }

        $num = intval($this->db->fetchObject($this->db->select(array('COUNT(cid)' => 'num'))->from('table.comments')->where('authorId = ?', $this->uid))->num);
        echo sprintf(isset($args[$num]) ? $args[$num] : array_pop($args), $num);
    }
}

在想调用的地方调用以下代码即可。

<?php
$uid = 1;
$author = Typecho_Widget::widget("XAuthor@" . $uid, "uid=" . $uid);
$author->postsNum(); // 输出该用户发表的文章数量
$author->commentsNum(); // 输出该用户的评论数量
?>
