POST的数据为空
下面是我想实现的：
用户点击编辑之后利用ajax调用一个新的界面，然后编辑完之后单击提交POST到后台操作
但是发现post之后都是空数据，是什么原因呢？该怎么解决呢？
下面是我的编辑页代码
<?php
session_start();
include("../conn/conn.php");
include("../inc/func.php");
$pw_id=$_GET['pw_id'];
$sql="SELECT `pw_id`,`k1`,`k2`,`k3`,year,`student_num`,`week_time`,`has_exam`,paee_work_theory.`remark`,`co_tid`,`verify`,`weeks`,paee_course.name FROM `paee_work_theory`,paee_course WHERE paee_course.pc_id=paee_work_theory.pc_id and pw_id='$pw_id' order by paee_work_theory.pw_id desc";
$record=mysql_query($sql,$conn);
$row=mysql_fetch_array($record);
header('Content-type:text/html;charset=GBK');
?>
