Question

我无法弄清楚为什么我的密码输出不正确，我的注册页面工作正常。我每次尝试登录时都会在我的网址中显示login =密码错误。我试图找到ot在线的每一个可能的问题，但没有任何帮助我。

    <?php 
    session_start();

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

    include_once 'dbt.inc.php';

    $username = mysqli_real_escape_string($conn, $_POST['username']);
    $password = mysqli_real_escape_string($conn, $_POST['password']);

    //error handlers
    if(empty($username) || empty($password)){
        header("Location: ../main_login.php?login=empty");
        exit();
    }
    else{
        $sql = "SELECT * FROM users WHERE user_username = '$username'";
        $run = mysqli_query($conn, $sql);
        $result = mysqli_num_rows($run);

        if ($result < 1) {
            header("Location: ../main_login.php?login=error");
            exit(); 
        }
        else{
            if ($row = mysqli_fetch_assoc($run)) {
                $hashedpasswordcheck = password_verify($password, $row['user_password']);
                if ($hashedpasswordcheck == false) {
                    header("Location: ../main_login.php?login=incorrect password");
                    exit();
                }
                elseif($hashedpasswordcheck == true){
                    //log in user
                    $_SESSION['user_id'] = $row['user_id'];
                    $_SESSION['user_first'] = $row['user_first'];
                    $_SESSION['user_last'] = $row['user_last'];
                    $_SESSION['user_email'] = $row['user_email'];
                    $_SESSION['user_username'] = $row['user_username'];
                    $_SESSION['user_password'] = $row['user_password'];
                    header("Location: ../main_login.php?login=success");
                    exit();

                }
            }
        }

    }
}
           else{
          header("Location: ../main_login.php?login=error");
         exit();
}



 ?>

如果您从password_verify获得错误的错误响应并且您知道它应该是正确的，请确保将哈希变量用单引号（＆＃39;）括起来而不是双引号（＆＃34;）。

在PHP中任何以$ inside双引号作为变量开头的东西。

除了正确之外，我的密码不正确
