Passing PHP Variable From One Dynamic Page to Another

Question

I am trying to pass on some variables using SESSION from one PHP page to the next.

The first page contains this code and after the user clicks submit, it goes to Page 2:

<!--SESSIONS TO PASS ON VARIABLES-->
<?php $_SESSION['file'] = $file; ?>
<?php $_SESSION['linecount'] = $linecount; ?>
<?php $_SESSION['priceperpost'] = $priceperpost; ?>
<?php $_SESSION['totalcost'] = $totalcost; ?>
<!--//SESSIONS TO PASS ON VARIABLES-->

And this is what I have on the next page, Page 2, after the form is submitted:

<!--VARIABLES FROM PREVIOUS PAGE-->
<?php $file = $_SESSION['file']; ?>
<?php $linecount = $_SESSION['linecount']; ?>
<?php $priceperpost = $_SESSION['priceperpost']; ?>
<?php $totalcost = $_SESSION['totalcost']; ?>
<!--//VARIABLES FROM PREVIOUS PAGE-->

But it is not getting the code because I am trying to echo the variables on Page 2:

  <u>Number of Posts:</u> <?php echo ($linecount); ?><br>
  <br>
  <u>Price Per Post:</u> $<?php echo ($priceperpost); ?> <br>
  <u>Total Cost:</u> $<?php echo ($totalcost); ?><br>
  <br>

Please help as I do not know what I am doing wrong, any help would be greatly appreciated.

Yes I have also called session_start

Here is the updated code:

 <?php 
session_start(); 
$_SESSION['file'] = $file;
$_SESSION['linecount'] = $linecount;
$_SESSION['priceperpost'] = $priceperpost;
$_SESSION['totalcost'] = $totalcost; 
?>

and on the next page

<?php
session_start();
$file = $_SESSION['file'];
$linecount = $_SESSION['linecount'];
$priceperpost = $_SESSION['priceperpost'];
$totalcost = $_SESSION['totalcost']; 
?>

If you called session_start() at the top of your file, before html and you still have the problem please tell us do you get any errors or notices ? — Siamak Motlagh, Jan 03 '13 at 21:22
On page one, where do the values of $file, $linecount, etc... come form? — ROY Finley, Jan 03 '13 at 22:43

Make sure that you are starting your session before creating the variables and before calling them back :

session_start();

Yes I have called session_start as you can see by the edit I placed in the question – Melissa Omotoso Jan 03 '13 at 21:28

Are you sure your variables are set i.e. $totalcost? A comment on your code. Unless, you are breaking in and out of PHP and HTML, you do not need to open and close PHP on every line.

This can be rewritten:

<!--SESSIONS TO PASS ON VARIABLES-->
<?php $_SESSION['file'] = $file; ?>
<?php $_SESSION['linecount'] = $linecount; ?>
<?php $_SESSION['priceperpost'] = $priceperpost; ?>
<?php $_SESSION['totalcost'] = $totalcost; ?>
<!--//SESSIONS TO PASS ON VARIABLES-->

As:

<?php
// SESSIONS TO PASS ON VARIABLES
session_start();
$_SESSION['file'] = $file;
$_SESSION['linecount'] = $linecount;
$_SESSION['priceperpost'] = $priceperpost;
$_SESSION['totalcost'] = $totalcost; 
// SESSIONS TO PASS ON VARIABLES
?>
