<div class="content_topp"> 商品销量显示月销量已销售或总销量二次开发教程-本文章以默认的ECShop模板为例作讲解：
ECShop模板前台页面商品的相关信息在/includes/lib_goods.php文件里，
那么，首先我们找到这个文件，在其末尾?>符号前添加下面这个函数(月销量和总销量二者任选其一)
月销量：
function ec_buysum($goods_id)
{
$LMonth=strtotime("last month"); //前一个月
$nowTime=time(); //当前时间
<div class="line number5 index4 alt2" style="font-family: Monaco, Menlo, Consolas, 'Courier New', monospace; background-color: rgb(245, 245, 245); line-height: 14.296875px; font-size: 13px; white-space: normal; border-top-left-radius: 0px !important; border-top-right-radius: 0px !important; border-bottom-right-radius: 0px !important; border-bottom-left-radius: 0px !important; background-image: none !important; border: 0px !important; bottom: auto !important; float: none !important; left: auto !important; margin: 0px !important; outline: 0px !important; overflow: visible !important; padding: 0px 1em !important; position: static !important; right: auto !important; top: auto !important; vertical-align: baseline !important; width: auto !important; box-sizing: content-box !important; min-height: inherit !important;"> $sql="select sum(goods_number) from " . $GLOBALS['ecs']->table('order_goods') . " AS g ,".$GLOBALS['ecs']->table('order_info') . " AS o WHERE o.order_id=g.order_id and g.goods_id = ".$goods_id." and o.pay_status=2 and o.add_time >= ".$LMonth." and o.add_time |
