我正在创建一个反馈页面，允许用户提供反馈并使用 php 和 mysqli 将此反馈存储在数据库中，而无需使用 jquery 和 ajax 刷新页面，但问题是我没有得到任何插入的数据，尽管我得到了成功如果有人可以帮助我，我将不胜感激
反馈表格.php
<?php
session_start();
$login = ($_SESSION['login']);
$userid = ($_SESSION['user_id']);
$login_user = ($_SESSION['username']);
$fname = ($_SESSION['first_name']);
$lname = ($_SESSION['last_name']);
$sessionaddres =($_SESSION['address']);
?>
