打开goods.php

找到$smarty->display('goods.dwt', $cache_id);

下面添加

//获得订单数量

function selled_count($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');
}

}

找到$smarty->assign('now_time', gmtime());

上面添加

$smarty->assign('order_num',selled_count($goods_id));

然后打开goods.dwt

{$order_num} 进行添加即可。

这样就OK了。即可以调用购买数量了。
