帝国cms怎样做下载日、周、月排行功能？

第一步:

第二步:

//日下载数
elseif($down==7)
{
$r=$empire->fetch1("select DayHits from {$dbtbpre}ecms_".$cr['tbname']." where id='$id' limit 1");
$shownum=$r['DayHits'];
}
//周下载数
elseif($down==8)
{
$r=$empire->fetch1("select WeekHits from {$dbtbpre}ecms_".$cr['tbname']." where id='$id' limit 1");
$shownum=$r['WeekHits'];
}
//月下载数
elseif($down==9)
{
$r=$empire->fetch1("select MonthHits from {$dbtbpre}ecms_".$cr['tbname']." where id='$id' limit 1");
$shownum=$r['MonthHits'];
}

第三步:

$usql=$empire->query("update {$dbtbpre}ecms_".$class_r[$classid][tbname]." set totaldown=totaldown+1where id='$id'");

$usql=$empire->query("update {$dbtbpre}ecms_".$class_r[$classid][tbname]." set totaldown=totaldown+1,DayHits=DayHits+1,WeekHits=WeekHits+1,MonthHits=MonthHits+1 where id='$id'");

第四步:

<script src=[!--news.url--]e/public/ViewClick/?classid=[!--classid--]&id=[!--id--]&down=7></script>

<script src=[!--news.url--]e/public/ViewClick/?classid=[!--classid--]&id=[!--id--]&down=8></script>

<script src=[!--news.url--]e/public/ViewClick/?classid=[!--classid--]&id=[!--id--]&down=9></script>

第五步:

<?php
$usql=$empire->query("update {$dbtbpre}ecms_download set DayHits=0"); //不同的数据表，自己修改下，我用的是下载模型。所以是 download
?>

<?php
$usql=$empire->query("update {$dbtbpre}ecms_download set WeekHits=0");
?>

<?php
$usql=$empire->query("update {$dbtbpre}ecms_download set MonthHits=0");
?>
