帐户恢复页面没有响应 [重复]答案

【问题标题】：Account Recovery Page not responding [duplicate]帐户恢复页面没有响应 [重复]
【发布时间】：2019-05-02 15:23:15
【问题描述】：

在此页面上，用户将输入他们的电子邮件，然后代码将首先检查该电子邮件是否存在于数据库中。如果电子邮件存在，代码应生成新密码并将其发送到用户的电子邮件。此外，数据库表：passwordreset 应该插入用户密码重置操作的记录以及更新用户的帐户信息，以便他们可以使用新密码登录。当我输入有效的电子邮件帐户进行检查时，表单提交但用户的信息表或密码重置表未更新。我不确定问题出在哪里。一点见解会有所帮助。

PHP：重置密码.php

<?php 
use PHPMailer\PHPMailer\PHPMailer;
include('functions.php');

if(isset($_POST['submit'])){

  $con = new mysqli('localhost','root','','db_dom');

  $email = $_POST['email'];

  //check if email entered is in DB
  $sql = $con->query("SELECT email FROM usr_t WHERE email='$email'"); 

  if ($sql->num_rows > 0) {

    //Generate new hashed password
    $newPassword = generateRandomString();
    $newPasswordHash = password_hash($newPassword, PASSWORD_BCRYPT);

    require_once "PHPMailer/PHPMailer.php";
    require_once "PHPMailer/Exception.php";

    $mail = new PHPMailer();
    $mail->addAddress($email);
    $mail->setFrom("support@webdominator.com", "Web Dominator");
    $mail->Subject = "User Account Password Recovery";
    $mail->Body = "
        Greetings,<br><br>

        We are pleased to inform you that your password recovery is successful.<br>

        Your new password is: " . $newPassword . "<br>If you didnt not request a recovery of your account password, please go to your account and change tyour password immediately. Thank you!<br><br>

        Kind Regards,<br><br>
        Support.";

    if ($mail->send()) {

      //insert record into account password reset table
      $time = date("Y-m-d H:i:s");
      $sql = "INSERT INTO passwordreset(id, user, time_reset) VALUES ('', '$email', '$time')";
      $con->query($sql);     

      //update user table with new hashed password
      $con->query("UPDATE usr_t SET password = '$newPasswordHash' WHERE email = '$email'");

      echo '<div class="alert alert-success">Please check your email inbox</div>';

    } else {
       echo '<div class="alert alert-danger">Something went wrong! Please try again.</div>';
    }
  } else {
    echo '<div class="alert alert-danger">Sorry! Email not found</div>';
  }
}
?>

functions.php

function generateRandomString(){
        $str = "QWERTYZXCVASDLKMBJFOPTMSV1234567890";
        $str = str_shuffle($str);
        $str = substr($str, 0, 10);
        return $str;
}

回答：我不知道问题是什么，但我决定尝试另一种方式，使用 ajax 代码进行提交并更改了几行。现在我的代码可以工作了，用户可以在通过必要的验证后收到一封电子邮件，即电子邮件是否有效？这是最终代码：

忘记密码.php：

<?php 
use PHPMailer\PHPMailer\PHPMailer;
include('functions.php');

if(isset($_POST['email'])){

  $con = new mysqli('localhost','root','','pd.com');

  $email = $con->real_escape_string($_POST['email']);

  //check if email entered is in DB
  $sql = $con->query("SELECT email FROM usr_t WHERE email='$email'"); 

  if ($sql->num_rows > 0) {

    $newPassword = generateRandomString();
    $newPasswordHash = password_hash($newPassword, PASSWORD_BCRYPT);

    require_once "PHPMailer/PHPMailer.php";
    require_once "PHPMailer/Exception.php";

    $mail = new PHPMailer();
    $mail->addAddress($email);
    $mail->setFrom("support@pd.com", "PD");
    $mail->Subject = "Account Password Recovery";
    $mail->isHTML(true);
    $mail->Body = "
        Greetings,<br><br>

        Support.";

    if ($mail->send()) {

      //insert record into account password reset table
       $sql = "INSERT INTO `passwordreset` (`id`, `user`, `time_reset`) VALUES (NULL, '$email', current_timestamp())";
       $con->query($sql);     

      //update user table with new hashed password
      $con->query("UPDATE usr_t SET password = '$newPasswordHash' WHERE email = '$email'");

      exit(json_encode(array("status" => 1, "msg" => 'Please check your email inbox!')));

    } else {
      exit(json_encode(array("status" => 0, "msg" => 'Something went wrong!')));
    }

  } else {
    exit(json_encode(array("status" => 0, "msg" => 'Sorry! Email not found!')));
  }
}
?>

【问题讨论】：

标签： php html mysql forms function

【解决方案1】：

插入语句中的字段 ID 不能为空。我将首先验证passwordreset 中的id 字段是否设置为自动增量。如果是，则应将 id 字段保留在查询之外，使其变为以下内容：

  $sql = "INSERT INTO passwordreset(user, time_reset) VALUES ('$email', '$time')";

【讨论】：

该死的。我可能忽略了这一点。谢谢
代码现在是正确的..但仍然没有发生任何事情
