忘记了用php发送邮件的密码

Posted 2023-01-06

这是我忘记的密码。。当我测试它时，它会很吸引人。它将新密码添加到数据库。但它没有向用户发送新的密码邮件

有人可以帮我解决这个问题吗？这会很有帮助。

<?php
   function generateRandomString($length = 15) 
    $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $charactersLength = strlen($characters);
    $randomString = '';
    for ($i = 0; $i < $length; $i++) 
        $randomString .= $characters[rand(0, $charactersLength - 1)];
    
    return $randomString;


include 'config.php';

$check=mysqli_num_rows(mysqli_query($conn,"SELECT * FROM users WHERE email='".$_POST['email']."'"));

        if($check==1)
        
            $users=mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM users WHERE email='".$_POST['email']."'"));
            $code=generateRandomString();
            $msg='Hy, '.$users['name'].' Your New Generated Password is: '.$code.'';
            $headers = "[Reset Password]";
            $mml($_POST['email'],'Reset Password',$msg,$headers);

            if($mml)
mysqli_query($conn,"UPDATE users SET password='".md5($code)."' where email='".$_POST['email']."'");

            echo '<div class="alert alert-success">
                      <strong>New Password Has Been Sent to Your Mail!</strong> Check Your Inbox.
                    </div>'; else 
echo '<div class="alert alert-warning">
                      <strong>Timeout, Try again later!</strong>.
                    </div>';


         else 
                echo '<div class="alert alert-danger">
                              <strong>User not found!</strong>.
                            </div>';
        
?>

答案

好的，您遇到了很多问题。正如评论所建议的那样，您目前根本没有调用实际的mail（）函数。

mail（）函数带有多个参数，如果构造不正确，则实际上会传递一些邮件问题。

此行：

 $mml($_POST['email'],'Reset Password',$msg,$headers);

应该是：

 $mnl = mail($_POST['email'],'Reset Password',$msg,$headers);

这将意味着如果FUNCTION成功，您将获得true / false布尔值。 （这并不一定意味着您的邮件会到达需要去的地方...）为了确保您的邮件实际上将到达预期的去处，您需要确保所有标头都正确构造，并且在此之上您的DNS记录配置正确（DKIM，SPF等）]

请考虑以下代码段：

    $hostname       = "yourhostname.org";
    $date           = date('r', time());
    $nameto         = "Mr. Target";
    $recipient      = "[e-mail]";
    $from           = "[e-mail]";
    $namefrom       = "Mr. Sender";
    $subject        = "Password Reset Thingy";

    $headers = [];
    $headers[] = "MIME-Version: 1.0";
    //  $headers[] = "Content-type: text/plain; charset=iso-8859-1";
    $headers[] = "Content-type: text/html; charset=utf-8";
    $headers[] = "From: $namefrom <$from>";
    $headers[] = "Sender: $namefrom <$from>";
    //  $headers[] = "Bcc: Some Other Dude <[e-mail]>";
    $headers[] = "Reply-To: $namefrom <$from>";
    $headers[] = "To: $nameto <$recipient>";
    $headers[] = "Subject: $subject";
    $headers[] = "Message-ID: <". sha1(microtime(true)) ."@$hostname>"; //This is essential for getting to Gmail addresses.... 
    $headers[] = "X-Mailer: PHP/".phpversion();
    $headers[] = "Date: $date";
    $headers = implode("\r\n", $headers);

    $mnl = mail($recipient,$subject,$body,$headers,"-f $from") ;

因此，在邮件功能中包括-f开关很重要（强制其发送），此外，还需要尽可能详细地构造标题，以避免被垃圾邮件过滤器接收。您将不得不在自己的时间内阅读有关正确的标头构造的信息，这超出了我在这里想要键入的范围。

PHP的邮件功能通常是挑剔的，但是，您可以考虑将PHPMailer作为一个类使用，这会使很多事情变得容易得多。

或者您可以考虑使用套接字或其他东西，然后编写自己的功能以通过SMTP发送它，这是我有时要做的，以下功能是我通常在芯片故障时使用的功能，它将至少为您提供一个起点从...开始工作。

    function authSendEmail($from, $namefrom, $to, $nameto, $subject, $headers, $message) 


$smtpServer = "mail.yourhostname.com";
$port = "25"; //Or whatever the default port on your server is
$timeout = "30";
$username = "[e-mail]";
$password = "myemailpassword";
$localhost = "yourhostname.com";
$newLine = "\r\n";
$date = date('r', time()); 


    //Connect to the host on the specified port
$smtpConnect = fsockopen($smtpServer, $port, $errno, $errstr, $timeout);
$smtpResponse = fgets($smtpConnect, 515);
if(empty($smtpConnect)) 
    $output = "Failed to connect: $smtpResponse";
    return $output;
 else 
    $logArray['connection'] = "Connected: $smtpResponse";


   //Request Auth Login
fputs($smtpConnect,"AUTH LOGIN" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['authrequest'] = "$smtpResponse";

    //Send username
fputs($smtpConnect, base64_encode($username) . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['authusername'] = "$smtpResponse";

    //Send password
fputs($smtpConnect, base64_encode($password) . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['authpassword'] = "$smtpResponse";

    //Say Hello to SMTP
fputs($smtpConnect, "HELO $localhost" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['heloresponse'] = "$smtpResponse";

    //Email From
fputs($smtpConnect, "MAIL FROM: $from" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['mailfromresponse'] = "$smtpResponse";

    //Email To
fputs($smtpConnect, "RCPT TO: $to" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['mailtoresponse'] = "$smtpResponse";

    //The Email
fputs($smtpConnect, "DATA" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['data1response'] = "$smtpResponse";

fputs($smtpConnect, "To: $to\nFrom: $from\nSubject: $subject\n$headers\n\n$message\n.\n");
$smtpResponse = fgets($smtpConnect, 515);
$logArray['data2response'] = "$smtpResponse";

     // Say Bye to SMTP
fputs($smtpConnect,"QUIT" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['quitresponse'] = "$smtpResponse";

//Show log
//  echo "<pre>$to<br/>";
//  print_r ($logArray);
//  echo "</pre><hr />";
    $output = $logArray;
    return $output;
   
然后您可以这样称呼它：

$result=authSendEmail($from,$fname,$to,'Password Reset Subject',$subject,$headers,$message) ; //Use SMTP
var_dump($result);
希望这会以某种方式帮助您塑造形状！
