i have page findroom.php that will redirect to the page DisplayDetails.php. i wanted the DisplayDetails.php page to display data from the query in the page findroom.php. The data that i wanted to display from the query from page DisplayDetails is 'room_price' and 'room_type'. However, when i clik the Book Now link, it dosesnt't display the value. Since i'm just a starter in php, can someone tell me am i treating the session the right way as it doesn't diplay any result for the data that i wanted to take from the query in the findroom.php. But, for the the others data which is 'checkin', 'checkout' and others, it just show perfectly. I do hope if someone can tell me am i using the session in the right way or not. below is the code: findroom.php <?php session_start(); unset($_SESSION['error']); // echo variable from the session, we set this on our other page $_SESSION['checkin'] = $_POST['checkin']; //$_SESSION['checkin']=$checkin; $_SESSION['checkout'] = $_POST['checkout']; $_SESSION['rooms']= $_POST['rooms']; $_SESSION['adults']= $_POST['adults']; $_SESSION['children']= $_POST['children']; $days = (strtotime($_POST['checkout']) - strtotime($_POST['checkin'])) / (60 * 60 * 24); $_SESSION['days']=$days; $_SESSION['room_price']=$data['room_price']; $room_price=$_SESSION['room_price']; $_SESSION['room_type']=$data['room_type']; $room_type=$_SESSION['room_type']; ?> <html> <body> <form action="DisplayDetails.php" method="post"> <p> <?php //$result = mysql_query("SELECT id_no,room_type,room_price from room1 WHERE room_no NOT IN ( SELECT id_room_no //FROM reservation1 WHERE datein >='$datein' AND dateout <='$dateout')"); $result = mysql_query("SELECT room_price, room_type from room1 WHERE room_no NOT IN ( SELECT id_room_no FROM reservation1 WHERE datein >='$datein' AND dateout <='$dateout')"); ?> <?php /*if(isset($_POST['Check']) && $_POST['Check']=='Submit') { echo "The rooms availale on the date of :"; echo $datein; echo " until "; echo $dateout; } */ ?> </p> <p><strong><strong>Room Availbility</strong> </p> <td><table width="61%" height="64" border="1" cellpadding="0" cellspacing="0" bordercolor="#CC66CC" class="report2"> <tr> <td width="190" bgcolor="#E8E8E8"><div align="center"><strong>Room Type </strong></div></td> <td width="218" bgcolor="#E8E8E8"><div align="center"><strong>Room Price </strong></div></td> <td bgcolor="#E8E8E8"><strong>Task</strong></div></td> </tr> <?php //$counter=1; while ($data = mysql_fetch_array($result)): ?> <tr> <td><?php echo $data['room_type']; ?></td> <td><?php echo $data['room_price']; ?></td> <td width="153"><label><a href="DisplayDetails.php?id_no=<?php echo $data['id_no'];?>"><strong>Book Now</strong></a></label></td> </tr> <?php //$counter++; endwhile; ?> </table> <table width="373" border="1"> <tr> <td colspan="2"><strong>Reservation Summary</strong></td> </tr> <tr> <td>Check In :</td> <td><label> <?php echo $_SESSION['checkin']; ?> </label></td> </tr> <tr> <td>Check Out :</td> <td><label><?php echo $_SESSION['checkout']; ?></label></td> </tr> <tr> <td>Rooms :</td> <td><label><?php echo $_SESSION['rooms']; ?></label></td> </tr> <tr> <td>Adults Per Room :</td> <td><label><?php echo $_SESSION['adults']; ?></label></td> </tr> <tr> <td>Children Per Room :</td> <td><label><?php echo $_SESSION['children']; ?></label></td> </tr> <tr> <td>Days :</td> <td><?php echo $_SESSION['days']; ?></td> </tr> </table> <p> <label></label> </form> </body> </html> Code (markup): below is the code for : DisplayDetails.php <?php session_start(); $_SESSION['days']= $_POST['days']; $_SESSION['room_price']= $_POST['room_price']; $_SESSION['room_type']= $_POST['room_type']; // echo variable from the session, we set this on our other page //$_SESSION['checkin'] = $_POST['checkin']; //$_SESSION['checkout'] = $_POST['checkout']; //$_SESSION['rooms']= $_POST['rooms']; //$_SESSION['adults']= $_POST['adults']; //$_SESSION['children']= $_POST['children']; ?> <html> <body> <h3><center> Room's Reservation </center></h3> <form action="DisplayDetails.php" method="post"> <table width="373" border="1"> <tr> <td colspan="2"><strong>Reservation Summary</strong></td> </tr> <tr> <td>Check In :</td> <td><label> <?php echo $_SESSION['checkin']; ?> </label></td> </tr> <tr> <td>Check Out :</td> <td><label><?php echo $_SESSION['checkout']; ?></label></td> </tr> <tr> <td>Rooms :</td> <td><label><?php echo $_SESSION['rooms']; ?></label></td> </tr> <tr> <td>Adults Per Room :</td> <td><label><?php echo $_SESSION['adults']; ?></label></td> </tr> <tr> <td>Children Per Room :</td> <td><label><?php echo $_SESSION['children']; ?></label></td> </tr> <tr> <td>Days :</td> <td><?php echo $_SESSION['days']; ?></td> </tr> <tr> <td>Room Type</td> <td><?php echo $_SESSION['room_type']; ?></td> </tr> <tr> <td>Room Price</td> <td><?php echo $_SESSION['room_price']; ?></td> </tr> </table> </form> </body> </html> Code (markup): any kinds of help really apprecited
