thinkPHP统计排行与分页显示功能示例

5年以前 | 阅读数：840 次 | 编程语言：PHP

本文实例分析了thinkPHP统计排行与分页显示功能。分享给大家供大家参考，具体如下：

1.分页参数

count 总数

firstRow 起始行

listRows 每一次获取记录数

list 每一页的记录（要与count对应一致就行）

2.分页对象

可以针对真实的数据表
也可以针对统计出来的数据表，或者说是虚拟的表
因为LIMIT是最后执行的，哪怕你进行group操作，哪怕你进行子查询

    // 排行榜
    public function ranklist(){
        $type = $this->_get('type','trim');
        $this->assign('type',$type);
        $opener_id = $this->opener_id;
        if($type == 0){ // 上月排行
          $arrLastMonth = $this->getLastMonthStartEndDay();
          $lastStartDay = $arrLastMonth['lastStartDay'];

          $where['b.addtime'] = array(array('gt',$b_time),array('lt',$e_time),'and'); 
        }

        M()->query('SET @rank =0;');

        $count   = count($all);
        $Page    = new Page($count, 10);
        $list    = M()->table('sh_opener a')->join('sh_user b on a.id = b.opener_id')->where($where)->group('a.id')->order('usercount desc')->limit($Page->firstRow.','.$Page->listRows)->field('count(b.id) as usercount,a.name,a.id')->select();
        foreach ($list as $k => $v) {
          $list[$k]['rank'] = $k + 1 + $Page->firstRow;
        }
        // 我的商户
        $my_user_count = $all[$opener_id]['usercount']?$all[$opener_id]['usercount']:0;
        $my_rank = $all[$opener_id]['rank']?$all[$opener_id]['rank']:'-';
        $this->assign('my_user_count',$my_user_count);
        $this->assign('my_rank',$my_rank);
        $this->assign('page',$Page->show());
        $this->assign('list', $list);
        $this->display();
    }
    // 获取上一月开始与结束日期
    private function getLastMonthStartEndDay(){
        $thismonth = date('m');
        $thisyear = date('Y');
        if ($thismonth == 1) {
          $lastmonth = 12;
          $lastyear = $thisyear - 1;
        } else {
          $lastmonth = $thismonth - 1;
          $lastyear = $thisyear;
        }
        $lastStartDay = $lastyear . '-' . $lastmonth . '-1';
        $lastEndDay  = $lastyear . '-' . $lastmonth . '-' . date('t', strtotime($lastStartDay)); //t 给定月份所应有的天数,28到31
        return array('lastStartDay'=>$lastStartDay,'lastEndDay'=>$lastEndDay);
    }

这里用的是thinkphp的分页类实现的。
