$_SESSION problem

autocolismo

Weird
I can't register session vars in my server, i mean they are registered only at the same page.

I have a login page with username and password;
if login is ok register session var 'username' then go to page 2
page 2 can't get that session var.

here is a part of phpinfo:

session
Session Support enabled

Registered save handlers files user

Directive Local Value Master Value
session.auto_start Off Off
session.bug_compat_42 Off Off
session.bug_compat_warn On On
session.cache_expire 180 180
session.cache_limiter nocache nocache
session.cookie_domain no value no value
session.cookie_lifetime 0 0
session.cookie_path / /
session.cookie_secure Off Off
session.entropy_file no value no value
session.entropy_length 0 0
session.gc_divisor 1000 1000
session.gc_maxlifetime 1440 1440
session.gc_probability 1 1
session.name PHPSESSID PHPSESSID
session.referer_check no value no value
session.save_handler files files
session.save_path /var/lib/php/session /var/lib/php/session
session.serialize_handler php php
session.use_cookies On On
session.use_only_cookies Off Off
session.use_trans_sid Off Off

Is there anything wrong with this configuration?
Anyone had same problem?
thanks!

Maybe if you showed the code that you are using someone sould help you with your problem.

autocolismo

example:
index.php:

session_start();
$loginUsername="myself";
$GLOBALS['Username'] = $loginUsername;
session_register('Username');
echo "<a href='next.php'>next page</a>";

next.php

session_start();
echo $_SESSION['Username'];

This simple thing wont work at the server.
and in the error log i get:
PHP Notice: Undefined variable: _SESSION

It's a server problem i just don't know what is it

Houdini

Try using this instead
index.php

<?php
session_start();
$loginUsername="myself";
$_SESSION['username']=$loginUsername;
echo "<a href='next.php'>next page</a>";
?>

next.php

<?php
session_start();
echo $_SESSION['username']; 
?>

That's not the problem it doesn't work either... The problem is not in the code! i think it's something in the server :s

Or in the client. Is it accepting cookies? If it isn't, you'll need to either turn session.use_trans_sid On or put the session ID in the URL.

Another thing you can try is converting your PHP Session page into an object, and then referencing that object via include() before any of your page code on each page. Like this:

<<< Put this code in a file called session.php in the same directory as your other pages>>>

<?php
class session {
   function session() {  /* class constructor */
      session_start();
   }
}
$session = new session;
?>

Then, in any page you want to use sessions or session variables, put the following code before any of your php or html code:

<?php
include('session.php');
?>

This way, you assure yourself that you are using your sessions on every page you might need them. This is object code, you might want to read up on it by searching for it on google, perhaps with the keywords: PHP object code tutorial

Hope this helps.

thank you all for your help, but nothing changed, i think its some other problem at the server, i'll try other configurations in php.ini

Here's something I've found from http://de.php.net/manual/en/ref.session.php that might be related to your problem. It's a comment by a user who was repeatedly losing login and session data, so it might be worth a look:

I just finished a marathon debugging session with sessions, and I wanted to share what I learned with the rest of the PHP community because this has been a problem I've battled on several projects before finally solving it today.

I am using sessions to register a user's ID, and every so often, for no apparent reason, the session would seem to expire and my logged-in user would get kicked out.

. . .

I was scratching my head as to why, on about 10% of the times I sent a user to a new page (a PHP page that didn't have any of the sessions stuff--no session_start() and no mention of any session variables), when they came back the session variables were all empty.

I came upon a clue when I used ini_set to change the session.save_path location. My idea was that maybe the session files in /tmp were being deleted by other users on the system or something. So I added this line before session_start():
<?php
ini_set('session.save_path',"/path/to/unique/dir/");
?>
I knew no one else was saving their sessions there, so I started logging in to my page and at the same time checking for the creation of new sess_* files. I noticed that sometimes, especially when I had problems, a second session file (that was empty) would appear.

What I realized was that the URL was changing from www.coryforsyth.com to coryforsyth.com. When the presence of the WWW changed, PHP thought it was a different session and created an empty one that caused my script to log me out. If I went to the location bar of my browser and added/removed the WWW (to the way it had been before), all was well and I was still logged in.

An incredibly thorny problem. I hope this post helps someone else fix it, or even better prevent it. I changed my hosting preferences to automatically add a WWW to my domain if it wasn't typed that way.

hummmmm, i'm going to check it out.
