yii2使用gridView实现下拉列表筛选数据
424
2024-01-14
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

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。
