Question

嗨。在我单击“提交”按钮之前，一切工作正常。

这是单击提交按钮之前的样子。但是，单击它后，将是这样。单击它之后，所有信息都变得不确定。有人可以帮我吗。

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'];

}

Answer 1

问题在于，提交信息后您没有将任何信息传递给页面。您的第一个示例将second :: [a] -> Maybe a second = go 0 where go 1 (x:_) = Just x go i (x:xs) = go (i+1) xs go _ [] = Nothing显示为HTTP get变量，这就是您用来定义其他所有内容的方法。在您的第二个示例中（提交之后），没有mime-type变量。您的代码无法获取信息，除非您将其与提交请求一起传递或再次包含mime，以便它可以执行相同的查找。

单击表单中的“提交”按钮后，所有内容都变得不确定
