php问题,你肯定会,帮我这个新手解决一下吧
页面原来显示数据库读取的数据是按照时间来排序的,我想添加两个按钮,一个是按年龄排序,一个是按照时间排序。
我的问题就是怎么一点按年龄排序这个控件就执行“select * from log order by l_age”;
一点按照时间排序就执行“select * from log order by l_time”。用submit或者select的onclick事件都行。或者您有什么更好的办法也行。谢谢了

------解决方案--------------------
表单






构造查询串
$orderkey = isset($_GET['orderkey']) && $_GET['orderkey'] == '按年龄排序' ? 'l_age' :'l_time';
$sql = "select * from log order by $orderkey";


------解决方案--------------------
PHP code
<?phpif ($_GET['order']=="age"){    $order="age";        }else{    $order="l_time";        }$sql="select * from log order by $order";?><a href="?order=age">按年龄排序</a><div class="clear">
                 
              
              
        
            </div>
