Hi Alex,

You can do so in different ways.
If you make a link to the next page, you can pass it via the URL:
http://www.mysite.com/nextpage.php?myvar=23

You can also store the variable in a session.
Look up SESSION at www.php.net to get started.
($_SESSION[] is per-user.)

You can also store the variable somewhere on a database or in a file.

What is the best way completely depends on what you are trying to achieve,
but you didn't tell us a lot.

Or if doing a post, you can store it in a hidden input field.

But... how to post a predefined variable?

The first step is to get php to send the predefined value to the web
browser. This may be done using SESSIONs.

session_start() ;
$_SESSION['predefined'] = $predefined;
session_write_c lose();
header('Locatio n: first_page.php' );

Then, in first_page.php, you get the predefined value back and place it
into a POST value.

session_start() ;
<form action="second_ page.php" method="POST">
<input type="hidden" name="predefine d" value="<?php echo
$_SESSION['predefined'];?>">
</form>

Now, the value of 'predefined' is available to second_page.php as a
$_POST value.

$predefined = $_POST['predefined'];

Does this help?

Use Sessions or write text files in a temporary location. Sessions are
better.

But if he simply wants to carry a value from one page to the next and he is
doing it via a hidden field in a post, does he really need the session?
