[RESOLVED] How to pass session value across pages?

devil_vin

Hi..anybody.I am newbie here and have a form which have to pass through other pages and display on that page.How can I achieved it?

For the first page,here is the script for session value:

 <?php
    session_start();
    for ($i = 1; $i <= 3; $i++) {
    $_SESSION['selected'][$i] = date('D d\t\h M', strtotime('+' . $i . ' days'));
    echo '<option>' . $_SESSION['selected'][$i] . '</option>';
    }

?>

After user selected the date,page redirect to second page and display the selected date.Thanks for your generious help...

to register a variable you can use the session_register()
and to unregister session_unregister()

Thanks for reply.I thought session_register() method is deprecated.However I have changed the script to be like the following,the session value still can't pass over.

reservation.php

<?php for ($i = 1; $i <= 3; $i++) {
$date = date('D d\t\h M', strtotime('+' . $i . ' days'));?>
 <option value="<?=$date;?>"><?=$date;?></option>
<?php } ?>

reservation2.php

<?php
session_start();
 $_SESSION['my_date'] = $_POST['rDate'];
.........
..........
<tr> 
 <label>You selected <?= $_SESSION['my_date']; ?>!</label>
</tr>
?>

In the first page there I included a javascript to validate null selection of drop down menu,I suspect that something might went wrong here.

<script language="JavaScript" type="text/JavaScript">
function validateDrop(date)
{
	var returnStatus = 1;

if (date.rDate.selectedIndex == 0) { //if user didn't select any date
	alert("Please select a date!");
	returnStatus = 0;
};

if (returnStatus) { // if date is selected
	window.location='reservation2.php'
}
}
</script>
...................
..................
<form action="reservation2.php" method="post" name="reservation" id="reservation">
....................
...................
<input name="continue" type="button" id="continue4" value="Continue" onclick="validateDrop(document.reservation)">

Do not use session_register. Just do a session_start(), then read and write values from and to the $SESSION array. You must have a session_start() on any page in which you want to access the $SESSION array, both for reading and writing.

Thanks for reply,problem resolved

function GoToNextPage(value){
  if(value != ""){
       document.location = 'reservation2.php?selected_date=' + value;
  }

<select name="rDate" onChange="GoToNextPage(this.value)">

<label>You selected <?= $_GET['selected_date']; ?>!</label>
