Question

我正在创建一个网站，允许用户注册帐户并使用它登录。
现在，我希望他们能够更新他们的用户名和电子邮件等详细信息。我已经按照指南here进行了操作，因为我碰巧在register.php中使用了与他相同的代码，但它没有用。我是php的初学者，所以请耐心等待！感谢帮助。

register.php

<form method="post" action="">
<select name="find">
        <option value = "a">I'm a regular customer</option>
        <option value = "b">TV advertision</option>
        <option value = "c">Phone directory</option>
        <option value = "d">Word of mouth</option>
</select>
<input type="submit" name="submit" value="submit"/>
</form>


if(isset($_POST['submit']))
{
$find=$_POST['find'];
switch($find) {
 case "a" :
    echo "<p>Regular customer.</p>";
    break;
 case "b" :
    echo "<p>TV advertision.</p>";
    break;
 case "c":
    echo "<p>Phone directory.</p>";
    break;
 case "d":
    echo "<p>Customer referred by word of mouth.</p>";
    break;
 default :
    echo "<p>We don't know.</p>";
    break;
}
}

当我输入editprofile.php时，页面为空白。这是我的 editprofile.php

    <?php

if(!empty($_POST['username']) && !empty($_POST['password']))
{
    $username = mysql_real_escape_string($_POST['username']);
    $password = md5(mysql_real_escape_string($_POST['password']));
}

$email = mysql_real_escape_string($_POST['email']);

$checkusername = mysql_query("SELECT * FROM users WHERE username = '".$username."'");

if(mysql_num_rows($checkusername) == 1)
{
    echo "<h1>Error</h1>";
    echo "<p>Sorry, that username is taken. Please go back and try again.</p>";
}
else
{
    $registerquery = mysql_query("INSERT INTO users (username, password, email) VALUES('".$username."', '".$password."', '".$email."')");
    if($registerquery)
    {
        echo "<h1>Success</h1>";
        echo "<p>Your account was successfully created. Please <a href=\"index.php\">click here to login</a>.</p>";
    }
    else
    {
        echo "<h1>Error</h1>";
        echo "<p>Sorry, your registration failed. Please go back and try again.</p>";
    }
}

?>

<h1>Register</h1>

<?php
include "base.php";
session_start();
?>

<?php
if(!empty($_SESSION['LoggedIn']) && !empty($_SESSION['username']))     
{

$nameuser = $_SESSION['username'];
$checkinfo = mysql_query("SELECT * FROM users WHERE username = '$nameuser'");

while($results = mysql_fetch_array($checkinfo,MYSQL_ASSOC)){

$id = $row['id'];
$username = $row['username'];    
$email = $row['email'];
}

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

$editNAME=$_POST['username'];
$editEMAIL=$_POST['email'];
$editID=$_POST['id'];

$editquery = mysql_query("UPDATE users SET username='$editNAME' , email='$editEMAIL'  WHERE id='$editID'");

if($editquery)  
    {  
        echo "<b>Success!</b>";  
        echo "Your profile was successfully updated. Please click<a href=\"profile.php\"> here </a>to view.";  
    }  
    else  
    {  
        echo "<b>Error</b>";  
        echo "<p>Sorry, your profile update failed. Please go back and try again.</p>";  
    }  
   }
 }

?>
