// User's Login 
    public function Login($username, $pass, $table_name){
        $password = SHA1($pass);
        if(!empty($username) && !empty($password)){
            $user = $this->link->prepare("SELECT * FROM $table_name WHERE username=? AND pass=?");
            $user->bind_param("ss", $username, $password);
            $user->execute();

                    if($result->num_rows==1){
                        session_start();
                        $row=$result->fetch_assoc();
                        $loginuser = $_SESSION['name']=$row['username'];

            echo "<p class='col-sm-4 mx-auto mt-5 alert alert-danger text-center'> Empty Login Details </p>";
        }
     }

这是处理我的登录表单的功能，它在Xamp上可用，但在实时服务器上显示错误。致命错误：未捕获错误：调用

中未定义的方法mysqli_stmt :: get_result（）

Answer 1

它需要mysqlnd驱动程序...如果未在您的网站空间中安装它，则必须使用BIND_RESULT＆FETCH！

extension=php_mysqli_mysqlnd.dll in php.ini;并重新启动Apache2

请阅读该方法的用户说明：

http://php.net/manual/en/mysqli-stmt.get-result.php

https://secure.php.net/manual/en/mysqli-stmt.bind-result.php

https://secure.php.net/manual/en/mysqli-stmt.fetch.php

代码在Xamp上有效，但在liveserver上无效
