请教高手，我在php生成的html(地址如：http://www.123.com/newinfo/2011/4848943.html)里加入以下代码 浏览次数：<iframe src="/postsclick.php" frameborder="0" scrolling="no"></iframe>
<iframe src="/postsclick.php?url=$_SERVER['REQUEST_URI']" frameborder="0" scrolling="no" height="35"></iframe>
postsclick.php的功能是得到点击次数，代码如下，
<?php
include('config.php');
error_reporting(E_ALL & ~E_NOTICE);
$clickurl =isset($_GET['url']) ? $_GET['URL'] : exit(0);
$newclick = $db->exe_sql("UPDATE `data01` SET `clicknum`=`clicknum`+1 where `url` like '%{$clickurl}'");
$newclicknum = $db->exe_sql("select `clicknum` from `data01` WHERE `url` LIKE '%{$clickur}'");
$info_click = mysql_fetch_assoc($newclicknum);
$info_clicknum = $info_click["f_clicknum"];
echo "浏览次数:".$info_clicknum;
?>
现在得到的结果是刷新当前html页面,当前浏览次数+1,但实际是后台数据库是第一条记录+1,然后其他页面也+1.
现在要怎么办?修改那些语句?
修改一下上面的语句
$info_clicknum = $info_click["clicknum"];
echo "浏览次数:".$info_clicknum;
?>
update的话以主键为更新条件：
UPDATE `data01` SET `clicknum`=`clicknum`+1 where urlid=".$id;这样保证唯一更新。

用ID传值，比较精准。
