ecshop教程：显示某商品销售累计效果的实现代码

方案如下： 修改 includes/lib_insert.php 文件， 增加一个函数  复制代码代码如下: /** * 调用某商品的累积售出 */ 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 = 0; } return $number; }  修改模板下goods.dwt文件 增加一行代码 <strong>累计售出：</strong>{insert name='goods_sells' goods_id=$id}{$goods.measure_unit}
