Sessions

Anon

I am having a large problem with sessions. How would I set a session variable that I can access from any page on my site. I have tried:

session_start();
session_register("session_rights");
session_register("session_Username");
session_register("session_Password");
session_register("session_FName");
session_register("session_LName");
session_register("session_Email");

$session_rights = $rights;
$session_Usrname = $username;
$session_Password = $password;
$session_FName = $FName;
$session_LName = $LName;
$sesison_Email = $Email;

Doesnt seem to wirk. I know I am probably doing this wrong. Thanks.

I think the proper way is to FIRST set the variables and THEN register them, that works fine for me.

example:

<?php
session_start();

$foo = "bar";

session_register("foo");

... other codelings ...

Good lucks!

In my opinion, you are doing it quite right.
Start the session, and register the variables is right.
The only problems I could see are:
-I dont put the "quotes" around the variable name when registering it... mine works fine.
-Are you using PHP4, because PHP3 does not support the session functions...
(I do have a library for PHP3 which allows you to do this though)

Good luck,
Andre

For my latest project I've created a "session handler" file that I include on every page that I need to see session variables on. In that session handler file I check to see if the session cookie has been has been set and if not, start a session. Here's a snippet for you to see what I'm talking about:

<?php

session_start();

if (!$PHPSESSID)
{
// register and set your variables
}
else if ( // session variables not set)
{
// register and set your variables
}

?

I do a include("session_handler.inc") command on every page of my site and the session variables follow me everywhere.

Hope this helps

Ok, I take that back, it works fine. Sorry.

Note though; the value of, for example, $session_rights (which you set to $rights) won´t change by just assigning a new value to $rights late on. You´ll have to set $session_rights = $rights every time that the $rights variable changes.

To assign your session variables to other variables; put an ampersand (&) before it, like this:

$session_rights = &$rights;

And viola, when the $rights get a new value later on in the script - the $session_rights will follow.

When I try to get the variable it doesnt pull it out. Is this correct? I just call the variable name when I want to use it? If i set a session variable called $session_rights, then in another function, or somewhere on my page I just call $session_rights?

Do I need to do something else?

Anywhere you want to use the variables, you need the session_id (PHPSESSID) and the session_start() command before you try to access the variables ...

Anon

When you are registering the variables, you had it right...
Now if you want to access the variables on another page...

Simply add session_start( ); at the top of the page.

Now you can access the variables you earlier registered.
Session_start checks to see if you have already registered variables. If you have, then you can access the variables. If you haven't, then a new session is started automatically.

This is the best site I have found for understanding session management.

Hi chris,

I had already done that but strangely enough the script worked fine when I included it all the files as long as they were in the same directory as the session script.

It does not work when i include that script in files out of that directory.

Any sugessions ??
