Question

我理解这可能不是最有建设性的问题而且我道歉（我是StackOverflow的新手，还在试图弄清楚如何使用它。）基本上我正在尝试创建一个基本的用户管理系统用户可以登录，但无法注册新帐户。只有管理员帐户才能添加新员工（用户）。我可以想出那个部分，只需要帮助我的插入脚本。请告诉我哪里出错了。

这是我收到的错误：

警告：mysql_query（）要求参数1为字符串，对象在第14行的C：\ xampp \ htdocs \ functions \ addemployee.php中给出错误：

我的表格：

                </div>
            </div>
        </div>
    </body>
</html>

我的插入脚本：

  <?php

 include("../includes/config.php");


$firstname = mysqli_real_escape_string($db,$_POST['firstname']);
$lastname = mysqli_real_escape_string($db,$_POST['lastname']);
$username = mysqli_real_escape_string($db,$_POST['username']);
$password = mysqli_real_escape_string($db,$_POST['password']);


$sql = "INSERT INTO employees (id, firtname, lastname, username, password) VALUES ('', '$firstname', '$lastname', '$username', '$password')";

if (!mysql_query($db,$sql)) {
    die('Error: ' . mysql_error());
}

?>

我的config / db连接脚本

    <?php
   define('DB_SERVER', 'localhost');
   define('DB_USERNAME', 'root');
   define('DB_PASSWORD', '');
   define('DB_DATABASE', 'breitinger');
   $db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
?>

如何使用PHP将数据插入MySQL数据库？
