ECShop顯示某商品銷售累計(jì)效果的實(shí)現(xiàn)代碼

    通過學(xué)習(xí)、查詢，解決該問題。
    方案如下：
    修改 includes/lib_insert.php 文件，
    增加一個(gè)函數(shù)
    代碼如下:
    /**
    * 調(diào)用某商品的累積售出
    */
    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 $number;
    }
    修改模板下goods.dwt文件
    增加一行代碼
    <strong>累計(jì)售出：</strong>{insert name='goods_sells' goods_id=$id}{$goods.measure_unit}
