Session problem

Drodil

Hello all!
I have little problem with sessions.. I have to make a region selection screen and it needs that it keeps the info of the users selection. This is my region.php:

<form action="index.php?page=home" method="post">
<p align="center"><select size="1" name="region">
<option>Region1</option>
<option>Region2</option>
<option>Region3</option>

</select><input type="submit" value="Submit"><input type="reset" value="Reset"></p>

in index.php i have lines:

session_start();

$SESSION['region'] = $POST['region'];

Now it should be in session with variablename of $region , am I right ? Now when I go to hyperlink somewhere inside the pages for example index.php?page=news it doesn't recognize the variable anymore.. So.. Am I doing this all wrong or where's the problem ?

Thank you.

And are you remembering to use session_start() on the other pages? What configuration settings are you using to control the session ID (have you turned both use cookies and use transparent SID off, for example)?

So I have to use session_start() on other pages too despite that my index.php includes the pages inside it ? And I have both use cookies and trans_SID off. Just can't understand where's the problem :/ Is it possible that the login script before the region session may interrupt the working while changing page. The login script is like:

<?php

if ($action == login) {
include "login.php";
}
elseif ($action == logout) {
session_start();
session_unset();
}
elseif (($user != NULL) && ($password != NULL)) {
$username = ("$user");
$password = ("$password");
include "login.php";
}
else {
session_start();
}
?>

And by the way.. Is there any other way to make this kind of system ? I REALLY NEED HELP !

Why are you using this

session_start();
session_unset();

From the manual

The session_unset() function frees all session variables currently registered.

Note: If $SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable, i.e. unset ($SESSION['varname']);.

So how do expect to use session variables set elsewhere?

So because you have all the automated methods for passing the session ID to the browser, you will have to put it in manually - see the section about SID in the [man]session[/man] chapters of the manual. (Or turn use_cookies or trans_SID on; see the documentation in php.ini for details).
