我对php相当陌生，并且在重新显示带有更新数据的表单时遇到问题；
到目前为止的故事：
我有通过电子邮件地址识别“用户”的注册和登录页面；在登录时，用户被带到他们自己的“会员”页面，该页面将显示该人持有的个人数据。然后，如果他们愿意，他们会被邀请编辑该数据。这会将他们带到“更新”页面，完成后，数据库会通过（隐藏的）“更新+ac”页面更新，然后返回到他们自己的“主”页面。问题是我无法让“会员”页面在表单中重新显示更新的数据，也无法让表单本身重新显示。
这是“会员”页面的相关代码：（我还没有编写任何安全或验证代码 - 这一切都在本地主机上 - 我想先正确编码）
<?php
include_once 'login.php';
include_once 'functions.php';
if (isset($_SESSION['user']))
{
$user = $_SESSION['user'];
mysql_connect($dbhost, $dbuser, $dbpass) or die(mysql_error());
mysql_select_db($dbname) or die("Unable to connect: " . mysql_error());
$data = "SELECT * FROM `names` WHERE email='$user'";
$result=mysql_query($data) or die(mysql_error());
while($row=mysql_fetch_array($result)){
}
?>
<table border='1px' style="background-color:#F0F8FF; font-weight: bold;" >

<form method="post" action="update.php">
<input name="Submit1" type="submit" value="Edit" style="width: 67px" /></form>
</p>
<p> </p>
以下是“update.php”页面的代码：
<?php
include_once 'login.php';
include_once 'functions.php';
session_start();
// Connect to server and select database.
mysql_connect($dbhost, $dbuser, $dbpass) or die(mysql_error());
mysql_select_db($dbname) or die("Unable to connect: " . mysql_error());
// get value of id that sent from address bar
if (isset($_SESSION['user']))
{
$user = $_SESSION['user'];
// Retrieve data from database
$sql="SELECT * FROM names WHERE email='$user'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);
}
?>
<table width="400" border="0" cellspacing="1" cellpadding="0">

</form>

<?
// close connection
mysql_close();
?>
最后，这里是“upate_ac.php”页面的代码：
<?php
include_once 'login.php';
include_once 'functions.php';
// Connect to server and select database.
mysql_connect($dbhost, $dbuser, $dbpass) or die(mysql_error());
mysql_select_db($dbname) or die("Unable to connect: " . mysql_error());
// update data in mysql database
$id = $_POST['id'];
$name = $_POST['name'];
$email = $_POST['email'];
$maintel = $_POST['maintel'];
$mobtel = $_POST['mobtel'];
$organisation = $_POST['organisation'];
$group_leader = $_POST['group_leader'];
$supervisor = $_POST['supervisor'];
$volunteer = $_POST['volunteer'];
$assessor = $_POST['assessor'];
$sql="UPDATE `names` SET id='$id', `name`='$name', `email`='$email', `maintel`='$maintel', `mobtel`='$mobtel', `organisation`='$organisation', `group_leader`='$group_leader', `supervisor`='$supervisor', `volunteer`='$volunteer', `assessor`='$assessor' WHERE `id`='$id''";
$result=mysql_query($sql);
// if successfully updated.
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='member.php?view=$user'>View result</a>";
}
else {
echo "ERROR";
}
?>
发生的事情是我得到“成功”和“查看结果”。当我点击“查看结果”时，我会进入“会员”页面，但没有显示任何表格。
我将不胜感激任何帮助。
