我有一个用于注册用户的页面，该页面将数据存储到名为车库的数据库中。最初，该表格运行良好，可以将数据保存到数据库中，但是现在我一直遇到错误。表单将以下字段存储到表admin_users中（名字，姓氏，id号，电子邮件，地址，电话号码，镇，adminuname，adminpass）。
这里有一些代码用于将数据存储到数据库中。
<?php
// Initialize the session
session_start();
// Check if the user is logged in, if not then redirect him to login page
// if(!isset($_SESSION["loggedin"]) || $_SESSION["loggedin"] !== true){
// header("location: index.php");
// exit;
// }
// registration
require 'includes/connect.php';
// Define variables and initialize with empty values
