Session variables how?

[niquil]

Hi i am building a login page with sessions.
The idea is that people can login and then get send to another page where they can do new things.
The first page has a few variables which i need in the second page.

So after the first page's session start()
i want to add a variabele to the session.

user_password with value 1234b
and user_login with value "bob"

then i want to read out these variables in the second page and use them in an sql statement.

how do i do this?
anyone knows some good reading on sessionvariables?

till now i have this:

1st page:

//some code

$Results = mysql_num_rows($Query);  

$results2 = mysql_fetch_array($Query);

if ($Results == '1') 
//username and password are ok
    {  

      $_SESSION[user_login]=$results2['user_login'];
      $_SESSION['user_password']='$user_password'; 
      $_SESSION['blaat']=$results2['blaat'];  

//some more code

2nd page

<?php
//Login needed for this page
 session_start(); 

//get values out of session
$user_login = $_SESSION['user_login'];
$user_password = $_SESSION['user_password'];
$blaat = $_SESSION['blaat'];


$query = mysql_query("select * from user where user_password = $user_password and user_login = $user_login;")
?>

I appreciate all help i can get!

thanks in advance!

You need to have session_start() on every page that uses the session.

Any changes to the session need to be made before any browser output is made. You can still read but you can't update the session after that.
