所以，当第一次进入页面时，它就像一个魅力。我写下我的反馈并按下提交按钮。数据库得到所有的信息，没有什么是错误的，但当我做一个刷新它写入数据库，同样的反馈形式再次，并取决于我刷新多少，它总是添加相同的评论……

</div>
<?php
$con = mysqli_connect("data for login");
if (isset($_POST['mod']))
{
$SQL = "INSERT INTO feedback_comment (rate, comment, name, skin, email) VALUES ('5', '$_POST[comment]', '$_POST[name]', '$_POST[skin]', '$_POST[email]')";
$result = mysqli_query($con, $SQL);
}
mysqli_close($con);
?>`
在数据库提交代码后添加unset($_POST);
所以，它们都没有真正工作，但我决定使用会话来提交带有header功能的页面，并且提交按钮没有功能…我不能得到这个去提交。php与标题位置只在按钮按下。｀
