ECShop显示某商品销售累计

最近在学习ECShop内容，

想在商品页面中将某一商品的累计销售数量显示出来。

通过学习、查询，解决该问题。

参照文章：

方案如下：

修改 includes/lib_insert.php 文件 ，

增加一个函数

/**
* 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;
}

/** * 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
累计售出：{insert name='goods_sells' goods_id=$id}{$goods.measure_unit}
