Problem with SESSION variables...

[ZoombyWoof]

Hi. Im very new to php, and I have a problem here that I cant find the
solution for. I have problems with session variables, I want some
variables to maintain their value between different php script that is
being called. I have read the online manual, and here is an example from
it that doesnt work for me, it illustrates very well my problem.

File 1, index.php

<?php
// index.php

session_start() ;

echo '<br />Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal'] = 'cat';
$_SESSION['time'] = time();


// Works if session cookie was accepted
echo '<br /><a href="page2.php ">page 2</a>';

// Or maybe pass along the session id, if needed
echo '<br /><a href="page2.php ?' . SID . '">page 2</a>';
?>

File 2, page2.php

<?php
// page2.php

session_start() ;

echo '<br />Welcome to page #2<br />';

echo $_SESSION['favcolor']; // green
echo $_SESSION['animal']; // cat
echo date('Y m d H:i:s', $_SESSION['time']);

// You may want to use SID here, like we did in page1.php
echo '<br /><a href="index.php ">page 1</a>';
?>

I get no output, except the date which shows 1970 bla bla

I have apache 2.0.48, PHP 4.3.3 running on a Redhat 9.0 box. I have not
touched the register_global s in php.ini, it's Off. What can be the problem
here ? Any help would be much appreciated, I'm stuck....

Thanx

What do you have for "session.save_p ath" in php.ini?
Does the webserver have write-access to that directory?

The above will only work if you set session.use_tra ns_sid in php.ini to 1.
Furthermore cookies must be accepted by your browser in order to work.

Alternatively you could use:

echo '<br /><a href="page2.php ?'.session_name ().'='.session_ id().'">page
2</a>';

Check the session cookie on page 2 with session_get_coo kie_params() .. if
that's empty, the cookie hasn't been set.

I have tried all of what you suggested above, setting use_trans_sid to 1
didnt help. I used the link with session_name=se ssion_id, didnt help. I
have changed session.save_pa th to /usr/local/apache2/sessions, apache owns
that directory, apache is the user who runs the server, but nothing goes
in that directory. I have checked the cookie_params, and it doesnt contain
anything else from what is set as default in php.ini.
I dont understand this....*HELP* :-)

Hm, strange, are you sure you are editing the php.ini PHP uses? Check with
phpinfo(). That will also tell you whether PHP was compiled with
--disable-session.

Yes, I'm editing the one PHP is using, it's /etc/php.ini, however, if you
mean that it should say --disable-session under configure command at the
top, it doesnt. Do I have to have disable-session compiled in ? Why is
this not the default, if it's necessary to get session to work...?

Did you restart the webserver after editing php.ini? That's a commonly
overlooked step...

Be sure that session.auto_st art is off.

session.save_ha ndler needs to be set to files for session.save_pa th to
be used.

session.use_coo kies should be on if you want to use cookies. If you want
to use *only* cookies, then session.use_onl y_cookies should be on as well.

Make sure that session.gc_maxl ifetime isn't set really low (default is
1440 seconds, or 24 minutes). Same with session.cookie_ lifetime, but 0
is no exipre in this case. (Watch for session.cache_e xpire as well.)

If id did say --disable-session, then sessions would be disabled and not
available on the server.

Check the under phpinfo() for "Configurat ion File (php.ini) Path" and be
sure that it is set to /etc/php.ini, otherwise all your edits will do
nothing. Also be sure to restart apache after editing.

session.save_pa th is local to the webserver filesystem.

session.cookie_ path is the HTTP path sent to the client in the cookie.
