这是我的代码

当我尝试运行编码时出现 2 个错误

Warning: mysql_real_escape_string() expects parameter 2 to be resource, null given in /home/a5008269/public_html/Login.php on line 9

PHP 错误信息

Warning: mysql_real_escape_string() expects parameter 2 to be resource, null given in /home/a5008269/public_html/Login.php on line 10

出于某种原因，我在第 9 行和第 10 行收到 2 个警告

请帮帮我

<?php
require_once('connector.php');

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

        $user_pass = mysql_real_escape_string(CONNECT, $_POST['password']);
