Session problem

[Anon]

Hi,

I tried to use the session_register -Function but I can`t get it working.
Im running:
PHP4.0.1pl2
Apache 1.3.12
Linux 2.2.13-SMP (SuSE 6.3) (1024 MB RAM, 2x700 PIII, RAID 10 Array)

this is what I did:

file: test1.php
<?php
session_start();
echo session_id();
$test = "Session test..";
session_register("test");
?>

file: test2.php
<?php

session_start();
echo session_id();
?>
<br>
<?php
echo $test;

?>

test2.php doesn`t print out the value of $test...... but the session_id() function works... (it prints out the same value on both pages)

I checked php.ini:

[Session]
session.save_handler = files ; handler used to store/retrieve data
session.save_path = /tmp ; argument passed to save_handler
; in the case of files, this is the
; path where data files are stored
session.use_cookies = 1 ; whether to use cookies
session.name = PHPSESSID
; name of the session
; is used as cookie name
session.auto_start = 0 ; initialize session on request startup
session.cookie_lifetime = 0 ; lifetime in seconds of cookie
; or if 0, until browser is restarted
session.cookie_path = / ; the path the cookie is valid for
session.cookie_domain = ; the domain the cookie is valid for
session.serialize_handler = php ; handler used to serialize data
; php is the standard serializer of PHP
session.gc_probability = 1 ; percentual probability that the
; 'garbage collection' process is started
; on every session initialization
session.gc_maxlifetime = 1440 ; after this number of seconds, stored
; data will be seen as 'garbage' and
; cleaned up by the gc process
session.referer_check = ; check HTTP Referer to invalidate
; externally stored URLs containing ids
session.entropy_length = 0 ; how many bytes to read from the file
session.entropy_file = ; specified here to create the session id
; session.entropy_length = 16
; session.entropy_file = /dev/urandom
session.cache_limiter = nocache ; set to {nocache,private,public} to
; determine HTTP caching aspects

session.cache_expire = 180 ; document expires after n minutes

What have I done wrong?

Martin,

I have been told there is a "bug" with the session function in php4. Sorry I can't help you more than that.

I have experienced almost exactly the same problem, using the sample files from this site.

In the apache error log, I am getting the following:

<b>Warning</b>: write failed: Bad file descriptor (9) in <b>Unknown</b> on line
<b>0</b><br>
<br>
<b>Warning</b>: Failed to write session data. Please check that the current set
ting of session.save_path is correct (/phpsessions) in <b>Unknown</b> on line <b

0</b><br>

the /phpsessions directory is one I created for this purpose, and is owned by the same user that runs the apache webserver.

/phpsessions contains files named like this:

sess_7ec31a321f14710b8f6f96be239e0a2c

which contains the session name as reported by php.

Any ideas?

I had the very same problem...

some where in this user group, some one had mentioned that you have to register your variables when you jump from one php file to another..

the solution to my problem what to 'register' the variable in question..

i.e.
in file x.php

session_start();
session_register('a');
$a="stuff";

in file y.php
session_register('a');
echo "$a";

the result would be..
stuff

from then on every thing worked as expected (at least as I expected).

hope this helps.

Hah. Fascinating.

My problem was that php was not able to correctly write to the /tmp directory where the session files are stored. This was reported as a problem with the current version, so I downloaded the latest snapshot.

it now works as advertised.

Your script revealed something interesting however.

If I do not put session_register("my_var") in the second file, then the value of the variable DOES get passed from script to script (as expected) but the value of
session_is_registered("my_var") is NULL. That is, PHP behaves as if the variable is registered (which is good enough for me!) but does not remember that it is registered.

If I look at the contents of the session file in /tmp, I see that $my_var value has been written there.

I am a experiencing a similar problem, if anyone can work this one out I would be very grateful.

My files look like this...

php file 1

session_start();

$user = $usrname; // username from form
$pass = $usrpassword; // password from form

session_register("user");
session_register("pass");
<a href="sessions3.php3?PHPSESSID=<? echo "$PHPSESSID"; ?>">NEXT</a>

?>

php file 2

echo "$user";

echo "$pass";

This works fine when cookies are turned on but I get a very strange message when cookies are turned off...
Warning: Failed to write session data (files).

Please verify that the current setting of session.save_path is correct (/tmp/) in Unknown on line 0

So I added session_save_path("/home/mattwilde/wildesites.net/temp/"); to the top of my php pages. Again it works when cookies are turned on and I can see the session files on my server in the temp directory as above. But when I turn cookies off again no session and no files get created.

You can see by visiting http://www.wildesites.net/test/session.html

If anyone can help...
Pleeeeeeeeeeeeeeeaaaaasssseee
B4 I go mad!

It is a while ago, so I am not sure I remember, but I believe this problem was resolved by upgrading to the then latest version of PHP.
