帝国cms二次开发之首页灵动标签内及列表页list.var自定义字段计算结果折扣率计算

效果图：

list.var代码：

$tagstr=dp_InfoTag($r['classid'],$r['id'],'| ',5);
$a=explode('|',$r[hangye]);
foreach($a as $key=>$val)
{
    if($key>0 && $key<(count($a)-1))
   {
        $colorimg.=''.$val.'';
    }
}
$fr=explode("|",$r[hangye]);
$zhe=round(($r[jiage]/$r[yuanjia])*10,1);
$sheng=($r[yuanjia]-$r[jiage]);
