I am working on a code where one php page sends values to second page and on second page users again adds some values and redirects them to another page where MySQL queries will be executed. I used require function to include second file but when I try to process the third page it gives me undefined index error.
my code is as below: for the first file named display.php
<html lang=en>
<head>
<title> Booking</title>
</head>
<body>
<div class="row">
<div class="col-md-3">
</div>
<div class="col-md-6" align="center">
<div class="model-content" align= "center">
<form method="POST" action="payment.php">
<input type="date" name="booking_start" required>
<input type="date" name="booking_end" required>
<input type="time" name="booking_start_time" required>
<input type="time" name="booking_end_time" required>
<?php
//we create a table
echo "<table background='img/parkingimg.png'>";
// create table th
echo "<tr > <th> Parking Slot No </th> <th> Status </th>";
$sql=" select ParkingSlotNo,Status from fleming_dwing ";
$st=$conn->prepare($sql);
$st->execute();
$total=$st->rowCount();//get the number of rows returned
if($total < 1 )
{//if no row was returned
echo "<tr> <td style> No Data: DataBase Empty </td> ";//print out error message
echo "<td> No Data: DataBase Empty </td> ";//print out error message
}
else
{
while($res = $st->fetchObject()){//loop through the returned rows
echo "<tr>";
if($res->ParkingSlotNo and $res->Status=='OCCUPIED')
{
echo "<td> $res->ParkingSlotNo </td> ";
echo "<td> <img src='img/occupied.png'/> </td>";
echo"<td><a href=''> </a> </td>";
}
elseif($res->ParkingSlotNo and $res->Status=='RESERVED')
{
echo "<td> $res->ParkingSlotNo </td> ";
echo "<td> <img src='img/registered.png'/> </td>";
echo"<td><a href=''> </a> </td>";
}
else
{
echo "<td> $res->ParkingSlotNo </td> ";
echo "<td> <img src='img/vacant.png'> </td>";
echo"<td><input name='parkingslot' type='checkbox' value='$res->ParkingSlotNo'></td>";
}
echo"</tr>";
}
}
?>
</table>
<input type="submit" value="Submit">
</form>
</div>
</div>
</body>
</html>
my second file is as below file name: payment.php
<?php
require_once ('navbar.php');
require_once ('dbconfigpdo.php');
$parkingslot = $_POST['parkingslot'];
$booking_start=$_POST['booking_start'];

$_SESSION['booking_end_time'] = $booking_end_time;
//$_SESSION['price'] = $price;
$a = new DateTime($booking_start_time);
$b = new DateTime($booking_end_time);
$interval = $a->diff($b);
echo $duration=$interval->format("%H");
echo $duration;
$price = '3' * $duration;
echo $price;
echo $parkingslot;

I can see and print session variable on second page(payment) but when I submit details to paymentsubmit page I am not able to get values there I mean when I try to print session variable it shows me null in variables and throws me above errors.
