在投票人名下计数,每日清空或转移
这个活动结束时是关于每个投票选项统计票数的,最好是怎么判断当天或24小时内的票数的例子
在投票人名下计数,每日清空或转移
已经说的很清楚了,就是几个字段解决:用户名、统计总数、统计当天总数、更新时间。基本就够你用了
建议 建一个日志表 做每一次的投票数据!以后要什么数据 都可以统计!
table
id 自增id
uid 用?id
date 日期
votenum 投票次?
判?是否已超? n次,如未超?,允?投票。
$n = 10;$uid = 1;$sqlstr = "select votenum from table where uid=".$uid." and date='2015-02-06'";$result = mysql_query($sqlstr) or die(mysql_error());if(!$result){ $sqlstr = "insert into table(uid,date,votenum) values('".$uid."','".date('Y-m-d')."',1)"; mysql_query($sqlstr) or die(mysql_error());}elseif($result['votenum']>$n){ echo '今天你已投票'.$n.'次,不能再投票'; exit();}else{ $sqlstr = "update table set votenum=votenum+1 where uid=".$uid." and date='".date('Y-m-d')."'"; mysql_query($sqlstr) or die(mysql_error());}// ?行投票代?echo '投票成功';
