我想将我忘记的密码连接到客户端电子邮件地址，我会尝试一下，但这不起作用。请帮忙，也许我的代码有问题。
这是我的PHP代码：
forgotpassform.php
<?php
session_start();
require_once('config.php');
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");
$email=$_POST['email'];
$username=$_POST['username'];
$sql = mysql_query("SELECT email, fname, lname, password, minitial, username FROM reg_form_students where username='$username'")
or die(mysql_error());
$row = mysql_fetch_array($sql);
$rownum = mysql_num_rows($sql);
$to= $row['email'];
$subject= "Online Library System Password Retrieval MESSAGE";
if(!$rownum ) {
echo "We can not find your email";
}
if($rownum ==1 ){
$message .= "Your account details:" . "\n\n";
$message .= "Username:". " " . $row['username']. "\n\n";
$message .= "Name:". " " . $row['lname'] . ", ". $row['fname'] . ", ". $row['minitial'] . "\n\n";
$message .= "Password:". " " . $row['password']. "\n\n";
$header = "";
$sent = mail($to,$subject,$message,$header);
if($sent)
{
print "Your password has been sent to your e-mail address </br>" ;
}
}
?>

请确保，如果您在本地运行代码，请设置您的SMTP身份验证＆amp; PHP.ini文件中的主机配置。
您的代码
if(!$rownum ) {
echo "We can not find your email";
}
if($rownum ==1 ){
更改为：
if(!$rownum ) {
echo "We can not find your email";
}
else
{
$to= $row['email'];
$subject= "Online Library System Password Retrieval MESSAGE";
根据您的信息：
Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in /home/a4664463/public_html/forgotpass.php on line 144
问题似乎从您的身份验证到连接到数据库。确保您输入的用户名和密码正确无误。密码。
尝试此更新：
if($rownum > 0)
{
$to= $row['email'];
$subject= "Online Library System Password Retrieval MESSAGE";
}
else
{
echo "We can not find your email";
}

将密码通过电子邮件发送给用户不是一个好方法，而是让用户通过发送提供的电子邮件地址的链接重置密码。
以下是mysqli编写的更好方法的版本。
创建一个名为“lost_password”的表，其中包含列，id，user_id，token。
以下脚本可能需要一些修复，但这比直接发送密码更好，一方面，因为您向用户发送密码，这意味着您在db中保存了普通密码，这是不推荐的。相反，你应该保存哈希值，如果你想这样做，你需要遵循以下方法。
<强> request_password.php
<?php
$db = new mysqli("localhost", "root", "password", "database_name");
if(isset($_POST['submit'])){
$email = $_POST['email'];
$stmt = $db->prepare("SELECT * FROM `users` where `email` = ?");
$stmt->bind_param('s', $email);
$stmt->execute();
$res = $stmt->get_result();
if($res->num_rows < 1){
echo "No such email has been found";
}
else{
$fetch = $res->fetch_assoc();
$userid = $fetch['id'];
$token = bin2hex(openssl_random_pseudo_bytes(45));
$url = 'http://yourwebsite.com/passwordreset.php?token='.$token;
if(mail($email, $url, $from)){
$stmt = $db->prepare("INSERT INTO `lost_password`(user_id, token) values(?,?)");
$stmt->bind_param('is', $userid, $token);
$stmt->execute();
if($stmt->affected_rows == 1){
echo "We have emailed you instructions on how to reset your password";
}
else{
echo "there was an error";
}
}
}
}
?>
<form action="" method="post">
<<input type="email" name="email">
input type="submit" name="submit">
</form>
<强> reset_password.php
if($_GET['token']){
$display_form = 0;
$stmt = $db->prepare("select * from `lost_password` where token = ? and `time` >= DATE_SUB(NOW(), INTERVAL 1 DAY");
$stmt->bind_param('s', $_GET['token']);
$stmt->execute();
$result = $stmt->get_result();
if($result->num_rows < 1){
echo "link has expired or token doesn't match the one we have on record";
}
else{
$display_form =1;
if(isset($_POST['submit'])){
$fetch = $res->fetch_assoc();
$id = $fetch['id'];
$hash = password_hash($newpass, PASSWORD_BCRYPT, array('cost' => 10));
$stmt = $db->prepare("update `users` set `password` = ? where `id` = ?");
$stmt->bind_param('ss', $hash, $id);
$stmt->execute();
if($stmt->affected_rows ==1){
echo "you have reset your password successfully";
}
}
}
}
if($display_form == 1){?>
<form action="" method="post">
<input type="text" name="newpass">
<input type="submit" name="submit">
</form>
<?php } ?>

这是我的更新，我仍在努力并且它有效，但它显示“我们找不到您的电子邮件”。
<?php
session_start();
require_once('config.php');
$username=$_POST['fp'];
$sql = mysql_query("SELECT * FROM reg_form_students where User_Name='".$username."'")
or die(mysql_error());
$row = mysql_fetch_array($sql);
$rownum = mysql_num_rows($sql);
if($rownum > 0)
{
$to= $row['E_Mail'];
$subject= "SFAC-OPAC Password Retrieval MESSAGE";
$message .= "Your account details:" . "\n\n";
$message .= "Username:". " " . $row['User_Name']. "\n\n";
$message .= "Name:". " " . $row['Last_Name'] . ", ". $row['Name'] . ", ". $row['Middle_Name'] . "\n\n";
$message .= "Password:". " " . $row['Password']. "\n\n";
$from = "From: admin@teampaper.com";
mail($to,$subject,$message,$from);
echo "Your password has been sent to your e-mail </br>" ;
}
else
{
echo "We can not find your email";
}
?>
