<div class="form-group">
<label for="psw"><span class="glyphicon"></span> Password</label>

【解决方案1】：

changepassword.php

在password和repassword之间将AND替换为,。
删除列名email 中的'。
将'email'=$result1 更改为email='$email'

改变

$query = mysql_query("update registered SET password = '$password' AND repassword ='$repassword' WHERE 'email'=$result1");

到

$query = mysql_query("update registered SET password = '$password', repassword ='$repassword' WHERE email='$email'");

用户需求。

因为，您正在向changepassword.php 发送电子邮件。您必须为email 创建一个hidden field，它将被提交到forgottenpassword.php 页面。

检查您的数据库连接。并且，交叉检查所有列名是否写正确。

按原样使用此代码。

ChangePassword.php

<form method="POST" action="forgotten.php" id="myform">
    <input type='hidden' value="<?php echo $_GET['email'];?>" name='email'>
    <div class="form-group">
    <label for="psw"><span class="glyphicon"></span> Password</label>
    <input id="password" class="form-control" type="password" name="password" placeholder="Enter password here" required/>
    </div>
    <div class="form-group">
    <label for="rpsw"><span class="glyphicon"></span>Confirm Password</label>
    <input id="repassword" class="form-control" type="password" name="repassword" placeholder="Retype password here" required/>
    </div>
    <button type="submit"  class="btn btn-success btn-block"><span class="glyphicon glyphicon-off"></span> Create New Password</button>
</form>

forgotten.php

<?
$connection = mysql_connect("localhost", "root", "") or die(mysql_error());
$db = mysql_select_db("db_name", $connection);

$email=$_POST['email'];
$password=$_POST['password'];
$repassword=$_POST['repassword']; 

$sql1="SELECT * FROM registered WHERE email ='$email'";
$result1=mysql_query($sql1);

$query = mysql_query("update registered SET password = '$password', repassword ='$repassword' WHERE email='$email'");

if($query)
{
    $to = $email;
    $from = 'mail@gmail.com';
    $subject="Password Changed";
    $message.="your password has been changed successfully. ";      
    $success = mail($to, $subject, $message);
    echo "Password has been changed successfully";
}
?>

不，它不工作并且不显示任何成功或失败消息
嗨@Nagu，首先，它会转到 changepassword.php 页面。您在哪里填写/插入 password 和 repassword 值。之后它会进入任何提交页面。 <form> 的代码在哪里？
我刚刚更正了您的错误。您的查询中存在哪个。如果它没有显示成功消息或其他，那么您的代码中有错误。要更正，您还必须提供<form> 的代码。然后，只有我们才能找到确切的问题。使用<form> 代码@Nagu 更新您的问题
密码
确认密码
@Nagu 你应该接受 Nana 的回答，因为他花了所有时间为你解决这个问题。访问meta.stackexchange.com/questions/5234/…，然后回来对复选标记做同样的事情，直到它变成绿色。
