!!Need Help With Sessions

Chris-the_dude

Hello, I'm a first time poster here.

I'm trying to run a very simple php script using sessions on my school's IIS server configured with PHP, and I'm getting a strange error.

The PHP code looks like this:

session_start();
session_register("sess_var");

$sess_var = "Hello world!";

echo "The content of \$sess_var is $sess_var<br>";

and the output looks like this:

Warning: open(C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\sess_2f83933bc5e9bce420915c740c01685d, O_RDWR) failed: m (13) in D:\resources\Students\chris-johnson\clickonchris\page1.php on line 3
The content of $sess_var is Hello world!

Warning: open(C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\sess_2f83933bc5e9bce420915c740c01685d, O_RDWR) failed: m (13) in Unknown on line 0

Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp) in Unknown on line 0

of course, you can see by yourself by going clicking here

Can I get some input from some of you PHP pros?

Thanks

This is the 4 or 5th post on the same topic in the last 2 days. You really should do a search before posting. Most times, your question has already been answered. In this case it was answered earlier today.

In any case, the problem is that you don't have a temp directory created. You need to create a directory for temporary files to be stored and make sure the permissions on that directory allow php to write to it.

Then check your php.ini file for the
session.save_path = /tmp
and make sure your directory path matches it.

On my local machine, I have a directory on the C drive called Apache and a directory under that called /tmp.
my php.ini file has
session.save_path = /tmp
and that works.

You may or may not have to enter the full path c:/Apache/tmp or whatever your directory is.

thanks keith.

sorry about the redundant posts

keith73

don't be sorry. You did say you are a first time poster.

Doing a search first makes things easier on you because you'll probably find your answer without having to wait for a reply.

I need a quick clarification. The temp directory you speak of must be created on the webserver, correct?

ofSHIZ

no, on your system....
it would store your sessions there.
i'm having this problem too so I should know..

Chris-the_dude

This doesn't make sense. So if I'm setting up a login using sessions, I would have to create a new temp directory at every computer I logged into the particular page from?

I've never seen any other websites do that before

ofSHIZ

no,
tmp is the place that is specified in your php.ini file
what it is set for is to hold your sessions. I would go into php.ini file, search for stuff that says "tmp" and change it to some place that every computer has, like the folder, temporary internet files.
I think everyone that would visit your site has that folder.

Chris-the_dude

not everyone has the same path to their temporary internet files though

NOPE, you got it all backwards.
/tmp is a DIRECTORY on the WEB SERVER.
in php.ini the session.save_path points to the directory that session files are saved to. A session file usually has a name like sess_abcdE456GHnkjiea89472jdmi38d
where everything after the _ is the session ID #.
You are NOT creating anything on the users computer. You may or may not set a cookie on their computer that contains the session ID, php will handle this automatically. If you don't use cookies, it will then automatically append the sesion ID to every link on your site. It would look like:
PHPSESSID=AvHGNAj432JAHafjanwo234nos

As I stated in my previous posts on the topic, if you are using apache, go the the apache root directory, create a directory called tmp and make sure the permissions allow apache to write to it. If on a Windows machine, you should just have to create it and make sure it isn't set to read only. On linux, you would have to CHMOD it.

And you should NEVER assume that everyone visiting your site has anything standard or that just because you have it, they have it too.

AHA!

That makes more sense. I'll have to talk to my networks admins and get some changes made around here!

I must be the first person at Augustana College using PHP sessions. interesting
