$sql = 'SELECT g.goods_id, g.goods_name, g.shop_price,g.promote_price,g.goods_thumb, SUM(og.goods_number) as goods_number ' .

2.第171行，$arr[$i]['price'] = price_format($arr[$i]['shop_price']); 替换为以下代码

if($arr[$i]['promote_price'] !='0.00'){
            $arr[$i]['price'] = price_format($arr[$i]['promote_price']);    
        }else{
            $arr[$i]['price'] = price_format($arr[$i]['shop_price']);    
        }
