session please help again

[johns]

Hello all again.

I got same help but there is new problem

I have a login file with two fields: username and password
Because I want to use variable username for other .php files so I declare session in login.php file as:

login.php
===========
<?
session_start();
session_register('username');
?>
.....
... get username from a form.....
....get password ..................

============

Now I want to assign the variable username of that user to a variable name in other get_name.php file and show username's table as bellow:

get_name.php
==============
<?

session_start(); //to get username from login file
$name = $username;
......
...Show username's TABLE....
......
?>

It is work well.

The new problem here is when I return "BACK" to previous login page and I login as another user (different with previous one), I went to the same page of the previous user, (that means it still show previous user's table)

I thought that I will use session_destroy() function like this:

login.php
===========
<?

session_destroy(); //destroy previous session
session_start(); //start new session
session_register('username');

?>


However, it still the same, after I login, I still went to the previous user's page !!!!!!!!!!!!!!!!.


(Please note that, I may use the same username variable for other pages)

Could you please help

Many thanks
john

Try refreshing the page, or setting the page to nocache in the meta headers.

Also, session_destroy() has proved to be unreliable in the past. Try setting the session variable to null or " ".

Good luck,
Jon.

Thanks but it still not work

you should have a logout page that will session_destroy() and also put this on access denied pages, so that way no one has anything that may involve a security risk.

try that out, thats how I do it.

Hello
Yes, I can have a logout.page but what I want is that I can "BACK" to previous login page event I do not logout yet. So I can login as another user.
Thanks
