storing object in session
|
|
| bmaster 2006-03-12, 6:56 pm |
| Hi there,
I'm trying to figure out how to store an object in session. To try this,
I have apache2 and php5 running on my windows machine. I used the 2
files below. First i run test.php, which creates the object, puts some
data in it, and stores it in the session. test2.php retrieves the object
from the session and prints the data. Works fine on my windows machine.
However, when I upload these 2 files to my hosting provider, then it
does not work anymore. I get no errors, but the object seems to be
empty. The provider is running php4.3 ... Can someone help me find a way
to fix this? Thanks!!
-------- test.php -----------------------------------------------------
<?php
class claUser{
var $firstname;
var $lastname;
}
session_start(); // Start Session
$user = new claUser;
$user->firstname = "abc";
$user->lastname = "def";
$_SESSION['user'] = serialize($user);
?>
-------- test2.php -----------------------------------------------------
<?php
class claUser{
var $firstname;
var $lastname;
}
session_start(); // Start Session
$user = new claUser;
if (isset($_SESSION['user']))
{
$user = unserialize($_SESSION['user']);
}
print $user->firstname;
?>

Get rid of the serialize/unserialize stuff, then read this:

I tried it with and without the serialize stuff, but neither worked. But
thanks for the link tho, session.auto_start is enabled indeed it seems.
I mailed my hosting provider to disable it, hope it helps. If not, I'll
be back :-) Thanks!

The provider adjusted the autostart session setting, but I still have
the same problem... Do you have any other ideas that I can try?
Thanks !!

Make sure error reporting is enabled (either by displaying the errors
or writing them to a log) and turned up. Run it again and see if you
get any messages.

| There are good reasons for using serialize/unserialize. However there
are complications using objects with sessions too as alluded to in the
thread ZB points to.
Your code looks fine bmaster - it should work.
The problem is that the session doesn't seem to get reloaded (maybe it
didn't get saved).
Check you got a session cookie. If possible, try to find the session
files, or use a different session handler.

I see the cookie called 'PHPSESSID' ... don't really know if I can see
what's in it.. ? If you say 'session files', do you mean the session
files on the server itself? Don't know if I have access to that... will
try that too later today. I'll get back with (hopefully) good results!

The PHPSESSID cookie is all I can see. Maybe this is normal, I don't
know. This is what phpinfo() tells me about the sessions: (sorry about
the layout)
Session Support enabled
Registered save handlers files user
Directive Local Value Master Value
session.auto_start Off On
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 /tmp /tmp
session.serialize_handler php php
session.use_cookies On On
session.use_only_cookies Off Off
session.use_trans_sid Off Off
Hope this can help.. ?
