ecshop顯示商品按月統(tǒng)計銷售數(shù)量

    代碼如下:
    $smarty->assign('goods_count', get_goods_coun($goods_id));
    最后在模板文件goods.dwt中 {$goods_count} 直接調(diào)用就行了。
    代碼如下:
    /**
    * 獲取商品出售總數(shù)
    *
    * @access public
    * @param integer $goods_id
    * @return integer
    */
    function get_goods_count($goods_id)
    {
    /* 統(tǒng)計時間段
    $period = intval($GLOBALS['_CFG']['top10_time']);
    if ($period == 1) // 一年
    {
    $ext = "AND o.add_time >'" . local_strtotime('-1 years') . "'";
    }
    elseif ($period == 2) // 半年
    {
    $ext = "AND o.add_time > '" . local_strtotime(‘-6 months’) . "'";
    }
    elseif ($period == 3) // 三個月
    {
    $ext = " AND o.add_time > '" . local_strtotime('-3 months’) . "'";
    }
    elseif ($period == 4) // 一個月
    {
    $ext = " AND o.add_time > '" . local_strtotime('-1 months') . "'";
    }
    else
    {
    $ext = '';
    }*/
    /* 查詢該商品銷量 */
    $sql = 'SELECT IFNULL(SUM(g.goods_number), 0) ' .
    'FROM ' . $GLOBALS['ecs']->table('order_info') . 'AS o, ' .
    $GLOBALS['ecs']->table('order_goods') . 'AS g ' .
    "WHERE o.order_id = g.order_id " .
    "AND o.order_status = '" . OS_CONFIRMED . "'" .
    "AND o.shipping_status " . db_create_in(array(SS_SHIPPED, SS_RECEIVED)) .
    " AND o.pay_status " . db_create_in(array(PS_PAYED, PS_PAYING)) .
    " AND g.goods_id = '$goods_id'";
    $sales_count = $GLOBALS['db']->getOne($sql);
    return $sales_count;
    }
    去掉注釋調(diào)用指定時間段內(nèi)。
