Question

我尝试创建更改密码页面，但我不知道如何获取用户ID（电子邮件）以完成更改。

这是我的更改密码页面，

＆＃13;

<form name="Change Password" class="form-horizontal" method="post" action="adminHandleChangePassword.php">

  <div class="form-group">

    <label for="InputPassword2">New Password</label>
    <input type="password" class="form-control" placeholder="New Password" name="newPassword">
    <label for="InputPassword3">Confirm New Password</label>
    <input type="password" class="form-control" placeholder="Confirm Password" name="confirmPassword">
  </div>
  <input type="submit" value="Change Password" class="btn btn-primary">

</form>

＆＃13;

这是我的adminHandleChangePassword.php页面，

＆＃13;

<?php

session_start();

require 'dbfunction.php';

$con = getDbConnect();

$password1 = mysqli_real_escape_string($con, $_POST['newPassword']);
$password2 = mysqli_real_escape_string($con, $_POST['confirmPassword']);
$user = mysqli_real_escape_string($con, $_SESSION['email']);

if ($password1 != $password2) { echo "Your passwords do not match.";}

else if (mysqli_query($con, "UPDATE adminaccount (email,password) VALUES ('$user', AES_ENCRYPT('$password1','tw8520'))"))
    {echo "You have successfully changed your password.";}

else { mysqli_error($con); }

mysqli_close($con);

?>

数据库数据，

Answer 1

首先这样做。用户名的形式必须有一个值，以便用户查看他的旧用户名。希望这可以帮助。随意提问：

$query=mysql_query("SELECT * FROM adminaccount WHERE email={$_SESSION['email']}");
if($fetch=mysql_fetch_assoc($query)){
 echo " <input type='email' class='form-control' value='".$fetch['email']."' name='email'> ";
}

Answer 2

如果您的数据库中有用户电子邮件，则不需要userID。我想的电子邮件是唯一的，或者你可能将user_id存储在$ _SESSION中。

Answer 3

我更改了代码的某些部分并且工作正常，

＆＃13;

if ($password1 != $password2) { echo "Your passwords do not match.";}

if (mysqli_connect_errno($con)) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
} else {
    mysqli_query($con, "UPDATE adminaccount SET password = AES_ENCRYPT('$password1','st2220') WHERE email = '$user'");

    if (mysqli_affected_rows($con) > 0) {
    	echo "You have successfully changed your password.";
    } else {
          echo "NO record updated.";
    }
    mysqli_close($con);
}
