分析ecshop赠品在购物车中出现

 

ecshop是一个非常灵活的电子商务系统,他可以在优惠活动中，为某个商品增加赠送礼品.不但可以设置价格,还可以免费赠送。

    在购物的时候,如果你选择了某商品,而且该商品又设置了赠送礼品，那么在购物车的cart页面，将会通过以下程序调用赠品.看下面以下ecshop函数

function favourable_list($user_rank)
{
    /* 购物车中已有的优惠活动及数量 */
    $used_list = cart_favourable();

    /* 当前用户可享受的优惠活动 */
    $favourable_list = array();
    $user_rank = ',' . $user_rank . ',';
    $now = gmtime();
    $sql = "SELECT * " .
            "FROM " . $GLOBALS['ecs']->table('favourable_activity') .
            " WHERE CONCAT(',', user_rank, ',') LIKE '%" . $user_rank . "%'" .
            " AND start_time <= '$now' AND end_time >= '$now'" .
            " AND act_type = '" . FAT_GOODS . "'" .
            " ORDER BY sort_order";
    $res = $GLOBALS['db']->query($sql);
    while ($favourable = $GLOBALS['db']->fetchRow($res))
    {
        $favourable['start_time'] = local_date($GLOBALS['_CFG']['time_format'], $favourable['start_time']);
        $favourable['end_time']   = local_date($GLOBALS['_CFG']['time_format'], $favourable['end_time']);
        $favourable['formated_min_amount'] = price_format($favourable['min_amount'], false);
        $favourable['formated_max_amount'] = price_format($favourable['max_amount'], false);
        $favourable['gift']       = unserialize($favourable['gift']);
        foreach ($favourable['gift'] as $key => $value)
        {
            $favourable['gift'][$key]['formated_price'] = price_format($value['price'], false);
    $favourable['gift'][$key]['goods_thumb'] = $GLOBALS['db']-> getOne("select goods_thumb from ".$GLOBALS['ecs']->table('goods')." where goods_id = $value[id]");

        }

        $favourable['act_range_desc'] = act_range_desc($favourable);
        $favourable['act_type_desc'] = sprintf($GLOBALS['_LANG']['fat_ext'][$favourable['act_type']], $favourable['act_type_ext']);

        /* 是否能享受 */
        $favourable['available'] = favourable_available($favourable);
        if ($favourable['available'])
        {
            /* 是否尚未享受 */
            $favourable['available'] = !favourable_used($favourable, $used_list);
        }

        $favourable_list[] = $favourable;
    }

    return $favourable_list;
}

    其中的gift值就是赠品的数据信息.而在模板flow.dwt中。

    !-- {foreach from=$favourable.gift item=gift} -->

      
       {$gift.name} [{$gift.formated_price}]
     

   就是循环显示赠品的相关信息.
