        //gallery =>img_url
        //goods goods.goods_desc  goods_name group_price  market_price  sell_count group_number

        C('DB_PREFIX')."goods g,".C('DB_PREFIX')."goods_description gd where g.goods_id=gd.goods_id and g.goods_id=".$goods_id;

        $goods_arr=M()->query($sql);

        $qian=array("\r\n");
        $hou=array("<br/>");
        $goods_arr[0]['summary'] = str_replace($qian,$hou,$goods_arr[0]['summary']); 

        $sql="select image from ".C('DB_PREFIX')."goods_image where goods_id=".$goods_id;
        $goods_image=M()->query($sql);

        $gallery = array();
        $default_image = '';
        foreach($goods_image as $val)
        {
            $val['img_url'] = str_replace('http','https',C('SITE_URL')).'/Uploads/image/'.$val['image'];

            if(empty($default_image))
            {
                $default_image = str_replace('http','https',C('SITE_URL')).resize($val['image'], C('goods_thumb_width'), C('goods_thumb_height'));
            }

            $gallery[] = array('img_url' => $val['img_url']); 
        }

        $goods = $goods_arr[0];
