Question

您好我正在为在线服务器创建一个登录系统，当我尝试登录时，我一直在试图抛出这个错误，我似乎无法找到解决这个问题的方法，任何帮助都会感激不尽。我看了一眼，人们说它是因为mysqlnd没有启用，但我检查了数据库php版本它是PHP 7.0，它启用，我似乎无法找到修复，任何帮助这个或安全登录提示非常感谢。

这是我的funtcion.php页面，它连接到process.php

   public function getUserByEmailAndPassword($email, $password) {

    $stmt = $this->conn->prepare("SELECT * FROM users WHERE email = ?");

    $stmt->bind_param("s", $email);

    if ($stmt->execute()) {
        $user = $stmt->get_result()->fetch_assoc(); // this line causes the error
        $stmt->close();

        // verifying user password
        $salt = $user['salt'];
        $encrypted_password = $user['encrypted_password'];
        $hash = $this->checkhashSSHA($salt, $password);
        // check for password equality
        if ($encrypted_password == $hash) {
            // user authentication details are correct
            return $user;
        }
    } else {
        return NULL;
    }

然后我的表格process.php页面

session_start();

require_once 'include/functions.php';
$db = new Functions();

// json response array

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

// receiving the post params
$email = $_POST['email'];
$password = $_POST['password'];

// get the user by email and password
$user = $db->getUserByEmailAndPassword($email, $password);

if ($user != false) {
    //user is found 
    $_SESSION['loggedin'] = true;
    $_SESSION["userid"] = trim($user["id"]);
    $_SESSION["first_name"] = $user["first_name"];
    $_SESSION["last_name"] = $user["last_name"];
    $_SESSION["email"] = $user["email"];
    //start session() and redirect to homepage.
    header("Location: ../dashboard.php");
} else {
    // user is not found with the credentials
    $_SESSION['Error'] = "Email or Password is Incorrect. Please try again!";
    header("Location:../signin.php");
}
}

PHP致命错误：调用未定义的方法mysqli_stmt :: get_result（）无法找到修复程序
