ecshop：产品页面添加商品销量，已显示OK

先在数据库写SQL进行查询，看看有没有结果：

SELECT SUM( goods_number ) AS number

FROM ecs_order_goods AS og, ecs_order_info AS oWHERE og.order_id = o.order_id

AND og.goods_id =209

可以查到3个销售数量，好了，现在开始改程序 ：

第一步：编写调用函数。在 includes/lib_insert.php 文件，最后加上以下函数/*** 调用某商品的累积已售出*/function insert_goods_sells($arr){ $sql = ‘SELECT SUM(goods_number) AS number ‘ . ‘ FROM ‘ . $GLOBALS[‘ecs’]->table(‘order_goods’) ." AS og , " . $GLOBALS[‘ecs’]->table(‘order_info’) ." AS o ". " WHERE og.order_id = o.order_id and og.goods_id=".$arr[‘goods_id’]; $row = $GLOBALS[‘db’]->GetRow($sql); if ($row) { $number = intval($row[‘number’]); } else { $number = 1; } return $number;}?>第二步：修改模板文件。修改themes/default夹下 goods.dwt文件在<strong>{$lang.goods_click_count}：</strong>{$goods.click_count}下面增加一行代码<strong>30天售出：</strong>{insert name=’goods_sells’ goods_id=$id}{$goods.measure_unit}

清除缓存，刷新页面OK了！

只要心中有希望存在，就有幸福存在。
