thinkPHP统计排行与分页显示功能示例

这篇文章主要介绍了thinkPHP统计排行与分页显示功能,结合实例形式分析了thinkPHP数据库查询与结果分页显示相关操作技巧,需要的朋友可以参考下

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

php
// 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'];
      $lastEndDay = $arrLastMonth['lastEndDay'].' 23:59:59'; 
      $b_time = strtotime($lastStartDay);
      $e_time = strtotime($lastEndDay);

    }

    $subQuery = M()->table('sh_opener a')->join('sh_user b on a.id = b.opener_id')->where($where)->group('a.id')->order('usercount desc')->field('a.id,count(b.id) as usercount,a.name')->select(false);
    $all = M()->table(''.$subQuery.' a')->getField('a.id,a.usercount,a.name,(@rank:=IFNULL(@rank,0)+1) as rank');
    $count   = count($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。
