php - 单击表单中的提交按钮后，一切都变得不确定

问题描述

你好。在我单击提交按钮之前，一切都运行良好。
这是单击提交按钮之前的样子。但是点击之后，就是这个样子了。单击它后，所有信息都变得未定义。有人可以帮帮我吗。
我不知道出了什么问题。这是我的代码。
    <?php
    session_start();  
if(!isset($_SESSION["user"]))
{
 header("location:index.php");
}

ob_start(); 
include ('db.php');

$pid = $_GET['pid'];



$sql ="select * from reservation where reservationno = '$pid' ";
$re = mysqli_query($con,$sql);
while($row=mysqli_fetch_array($re))
{
    $clientid = $row['clientid'];
    $name = $row['name'];
    $reservationno = $row['reservationno'];
    $invoiceno = $row['invoiceno'];
    $reservationdate = $row['reservationdate'];
    $totalamount = $row['totalamount'];

    $netamount = $row['netamount'];
    $cin = $row['reservefrom'];
    $cout = $row['reserveto'];

}

$asql ="select * from reservationdetails where reservationno = '$pid' ";
$are = mysqli_query($con,$asql);
while($row=mysqli_fetch_array($are))
{
    $cout2 = $row['checkout2'];
    $cout3 = $row['checkout3'];
    $days = $row['days'];
    $days2 = $row['days2'];
    $days3 = $row['days3'];
    $roomid = $row['roomid'];
    $roomid2 = $row['roomid2'];
    $roomid3 = $row['roomid3'];
    $qty = $row['qty'];
    $qty2 = $row['qty2'];
    $qty3 = $row['qty3'];

}
