首先直接做成一页，中间步骤的数据处理用JS，然后就可以正常提交，交给原系统的注册处理页面

我想用php 修改表单数据,要求在单独的修改页面执行

1、新建一个edit.php

2、在edit.php里调用要修改的记录，如果不会再问。

3、将调用的记录数据填充到 edit.php的form里去。

4、将form的action改为action="edit_save.php"

5、把搏大梁?php

$con=mysql_connect("localhost","root","");

if(!$con)

{

die('Coudl not connet:'仿正.mysql_error());

}

mysql_select_db("my_db", $con);

mysql_query("UPDATE Persons SET Firstname='".$_POST["firstname"]."',

Lastname='".$_POST["lastname"]."',Password='".$_POST["password"]."',Age='".$_POST["age"]."'");

mysql_close($con);

echo "scriptwindow.location.href='1.php';/script ";

?保基运存为edit_save.php

PHP表单处理问题

如果是用php处理的话，那就用把第一个input的时间取回来转换成unix timestamp，然后加上三个小时的秒基裂数，然后用date函数格式化成你想要搏空闭的格式。

要在前台解决的话亏敬，js取回来，也是格式化成timestamp，然后加上时间差的秒数，然后格式化回来
