ecshop如何在详情页显示销量

ecshop详情页显示销量

1.在good.php的最后添加代码

function selled_countgoods($goods_id)

{

$sql= "select sum(goods_number) as count from".$GLOBALS[‘ecs’]->table(‘order_goods’)."where goods_id=’".$goods_id."’";

$res = $GLOBALS[‘db’]->getOne($sql);if($res>0){return $res;}else{return(‘0’);}

}

2.在

$smarty->display(‘goods.dwt’,$cache_id);之前添加代码

$smarty->assign(‘order_num’,selled_countgoods($goods_id));

3.在goods.dwt页面里的调用：{$order_num}

，人生没有彩排，只有现场直播，所以每一件事都要努力做得最好
