[RESOLVED] Sessions are hard :-(

Hi guys,

I'm have some real problems with sessions.

I am using "RewriteEngine On" to make all my files.html

Anyway, i set my session in this file:

http://www.site.com/dir/dir/page.php

I set it like this:

session_start();
$_SESSION['refPage'] = 'ok';

Now i want to access this session file here:

http://www.site.com/dir2/page.php

with this:
session_start();
echo $_SESSION['refPage'];

But im getting a bad error:

Warning: session_start() [function.session-start]: open(/tmp/sess_644f0966b82ea08b861c90781dc1d911, O_RDWR) failed: Permission denied (13)

Please can someone help??

I dont know if it is somthing to do with the rewrite engine, and the site not going where the session file is or what?

Any help would be great.

Cheers.

I don't know for sure but it looks like apache (or whatever server software your using) doesn't have read / write permissions on the /tmp directory. I don't think this has anything to do do with the URL rewriting.

If this is the case, you need to chmod the /tmp directory to change the permissions on it (google chmod for more info).

To confirm if I am correct, you could type ls -lah / on the command line and past the results for /tmp here and I could prob see if there's a problem.

Contact your systems admin; this directory you're using for sessions is unwriteable - they will either fix this, or give you another one to use (which they should probably set in php.ini appropriately).

Cheers guys,

The problem is, i can write to the sessions on the first page.

I just cannot read from the page in the other directory.

Do you still think its a read/write issue on tmp?

How would i change session save folder and make sure every page reads from that folder?

Cheers.

Yes, it's the tmp directory:

Warning: session_start() [function.session-start]: open(/tmp/sess_644f0966b82ea08b861c90781dc1d911, O_RDWR) failed: Permission denied (13)

This means permission denied when trying to open the file: /tmp/sess_644f0966b82ea08b861c90781dc1d911

ok,

I've added this to my .htaccess file:

php_value session.save_path /home/account/www.site.com/sesstmp

and it's sorted the problem of the error, but it still dosnt work:

http://www.site.com/dir/dir/page.php

I have:

session_start();
$SESSION['refPage'] = 'ok';
echo $SESSION['refPage'];

On this page:

http://www.site.com/dir/dir/page2.php

I have:

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

And this works, it prints "OK"

But when i try the same on this page:

http://www.site.com/page.php

I dosnt work, there are no errors, it just looks like its not picking up the session.

Could this be because it is futher down the directories???

How can i solve this problem.

Thanks again for the help.

After a bit of testing...

This HAS to have somthing to do with the rewrite rule i have going on...

Does anyone have any experiance in sessions with mod rewrite.

I dont think the site can find its session.

Cheers.

Look in phpinfo() and find the "sessoin.cookie_path" setting. What is it set to?

Also... try echo'ing out [man]session_id/man on all pages - you should get the same ID every time. If you get a different ID, then the ID isn't being propogated properly and you should try setting "session.use_cookies" to On.

Please review your entire sessions config - it's possible that it's using a cookie which is set in some path other than "/" - this would cause the behaviour seen.

Consider writing a common function which configures all session ini parameters as necessary before calling session_start - call this function where you need to in your pages to ensure that they all have the same session config.
