session_start() issues

Robby_G

hello,
I was recommended to try using this function to allow me to continue to use variables as the use goes from one page to another, but what is a good manual page to clearly explain how to set this up?

clearly there's a lot to this! here's my current error:

Warning: session_start() [function.session-start]: open(/tmp\sess_941d6b3783dfbe1b31d92d6dfcfcde9e, O_RDWR) failed: No such file or directory (2) in D:\Program Files\Apache Group\Apache2\htdocs\horvath_site\index.php on line 2

and I can't make much of the comments posted after the explaination of the function here:
http://us2.php.net/function.session-start

thanks

there really ISN'T much to this

why don't you go ahead and post some current code you have so we can check it out, mmmm k, that would be terrific

Robby_G

okay but there isn't much as far as my current code. The following is the first 27 lines of my index page, and the very first thing I do is that session start statement!

<? 
		session_start() ;

	// reset topic from reference page.... right now this is on every page but reference.php

	$topic = $_REQUEST["topic"];
	$topic = '';

	//$current_dir = $_REQUEST["current_dir"];
	$current_dir = "legal_reference";
	print($current_dir);
	session_register($current_dir);

?>

I realize the above code doesn't even make any sense out of context, but it is this code thats erring.

stolzyboy

not sure if it is the forum doing it, but make sure you have this

<?
session_start();
?>

not what it looks like on the forum

<?
           session_start();
?>

Robby_G

okay I changed it, but uh, a) it didn't fix anything and b) why would it? I didn't think that tabs and spaces affected compilation!
(just proper coding style, right?)

stolzyboy

well for session_start();

it may change things, no whitespace before you have it

Robby_G

I'm sorry to say that this made no difference. Anything else I can try?

jimson

anyway, open a new file named it a.php, copy this and tell me ur result,
i want to know whether u php is configured correctly to use session.

<?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($_SESSION['count'])) {
    $_SESSION['count'] = 0;
} else {
    $_SESSION['count']++;
}
echo $_SESSION['count'];
?>

press refresh multiple times and u should see the number add 1 per refresh.

Hi,

I think you're running into a configuration problem. Make sure that the configuration parameter

session.save_path = c:/tmp

in your php.ini (located in the windows or winnt folder) points to an existing folder and restart the web server.

That should solve the problem.

Robby_G

okay that sounds good but I can't find my php.ini file. Is there one?

would file be needed for any user of my site?

jimson

click start, select run

type php.ini
there should be a file opened up

tsinka

Hi,

the easiest way is to create a little script that just contains

<?PHP
phpinfo();
?>

Near the top of the output you'll see a line whith a path where php searches for the php.ini. Make sure that a php.ini is there or copy the php.ini-dist there and rename it to php.ini.

Robby_G

click start, select run

type php.ini
there should be a file opened up

this fails.

<?PHP
phpinfo();
?>

this produces the explanation that my php.ini file is in D:\WINNT, but here is no such file there, and I checked to make sure hidden files are showing.

😕

stolzyboy

well on winnt that is where it should be

search your HD for php.ini, you surely have to have one if php is running

Robby_G

Already did that. Nothing comes up.

but that function claims its in the D:\WINNT dir, but for some reason I just can't see it... what could be happening?

jimson

reinstall PHP..

tsinka

Hi,

that's quite normal. You have to copy the php.ini-dist of the zipped php package to c:\winnt and rename it to php.ini. Then check the session.save_path parameter that it points to an existent directory.
