[SOLVED] Wierd Session warning

[R0bb0b]

Please look into this,

 

session_save_path("/some/path/to/dir/");

 

This ("/some/path/to/dir/"), should i leave it this way, or i must specify some path to a directory and if yes, what directory?

 

I hope you understand

 

You need to change the path to somewhere, I would say outside of the document root if you can.

[nitation]

This is 1-3 lines of session.php

 

<?php
session_start();
$afso_name=session_name();
$afso_sid=session_id();
?>

 

The below is 1-8 lines of login.php

 

<?php

session_start();

if (!isset ($_SESSION["admin_id"]))

{
  header ("Location:main.php?login=missing");
}

include("connect.php");

if($log){

$sqllog=mysql_query(" SELECT  * FROM  enter_code WHERE aname='$loginname' ");
?>

 

I put this code in the main file,

ini_set ("display_errors", "1");
error_reporting(E_ALL);

 

This is what it outputted;

Warning: session_start() [function.session-start]: open(/tmp/sess_d90f4557eceb9cdf247d9e5e5301e58f, O_RDWR) failed: Read-only file system (30) in /home/prudccou/public_html/session.php on line 2

[R0bb0b]

this is funny:

Notice: A session had already been started - ignoring session_start() in /home/prudccou/public_html/login.php on line 3

 

BTW: you don't need to call session_start() for every included file, just the first one.

@ R0bb0b

 

I placed session.php in my includes folder in /www directory

 

I believe my code should look like this;

 

ini_set("session.save_path","/public_html/includes/");

 

Also, what is funny about session had already started

I'm not exactly sure what the permissions on session files are, but I would assume that you would want to keep them outside of the document root, is that possible?

 

Its funny that the session is already started because if this is the case, it sounds like the issue happens randomly because if failed the first time and apparently succeeded later on.  Are you calling session_save_path() on the very first line of code that runs after your first "<?php" tag?  If not, that's what you want to do.

[PFMaBiSmAd]

A) Where in your code are you putting the line to set  session.save_path?

 

B) login.php and session.php are obviously being included by some main file. Post that code as well.

 

C) After the header() redirect in login.php, add a exit(); statement. I suspect this is partly responsible for the original error as that page will continue executing and the browser will request main.php, which I am going to guess contains or includes a file the contains a session_start();

 

@R0bb0b, his error reporting was set to prevent notice messages from being reported and the "Notice: A session had already been started" was occurring all along.

 

This code is a mess. There should only be one session_start() statement at the beginning of the page and the code that R0bb0b has given to set session.save_path must go before that single session_start().

 

I am going to guess that if the header() redirect is not causing the original error that this tangle of include statements/session_starts is what is causing the original error.

[aeonsky]

tmp is outside root, so I'd guess yeah. You should be able to save them outside public root.

 

By the way, are you using cPanel? I saw that you can actually change permissions on your tmp folder. You should try that!

[PFMaBiSmAd]

Setting the session.save_path is an attempt to work around a tmp folder that might have a problem. However, based on what the code is doing, it is likely the code is causing this and setting the session.save_path to a different folder won't have any effect on the original error.

<?
include("session.php");
include("connect.php");
include("admin/includes/en.php");
$return="Access Code";

if($login=="wrong"){
$return="Access code wrong";
}

else if($login=="missing"){
$return="Access code missing";
}
require("index_login.php");

?>

 

C) I have added exit after redirecting.

 

Take a look at the full code for login.php

 

<?php

session_start();

if (!isset ($_SESSION["admin_id"]))

{
  header ("Location:main.php?login=missing");
}

include("connect.php");

if($log){

$sqllog=mysql_query(" SELECT  * FROM  enter_code WHERE aname='$loginname' ");

if($sqllog){
$row=mysql_fetch_array($sqllog);
$rowid=$row["id"];
} 

$num=mysql_num_rows($sqllog);
if($num > 0){

$_SESSION["admin_id"]=$row["adminid"];
   header ("Location: index.php");
}
else
{
  header ("Location: main.php?login=wrong");
}

}
?>

Am i still missing something??? @ PFMaBiSmAD

[PFMaBiSmAd]

C) I have added exit after redirecting.

Except, I don't see any exit; statements in the code you posted for login.php.

 

Every header ("Location:some_url"); must have an exit; statement after it to prevent the remainder of the code from being executed. Your login code could be sending up to two header() redirects, both of which will be requested by the browser.

[nitation]

I posted the old long.php. I have added the exit(); and this is the error am getting.

[sKunKbad]

Maybe I'm wrong, but I think you need to call session_name() and session_id() before session_start().

[nitation]

session_name(), session_id() before session_start().

 

Am hearing that for the first time :X

[R0bb0b]

session_name(), session_id() before session_start().

 

Am hearing that for the first time :X

 

These should not be necessary.  At this point I would create one test file, start a session and play with the session variables.  This will allow you to determine if there is an issue with the server or your code.

[sKunKbad]

session_name(), session_id() before session_start().

 

Am hearing that for the first time :X

 

According to the php manual:

 

 

Description

string session_name ([ string $name ] )

 

session_name() returns the name of the current session.

 

The session name is reset to the default value stored in session.name at request startup time. Thus, you need to call session_name() for every request (and before session_start() or session_register() are called).

[DeanWhitehouse]

Lol, no you don't need to call session_name or session_id, you just need session start.

 

But if he can post his full code with the errors he may get a faster/better answer.

I know you don't need to call session_name or session_id, but he is in his code.

 

I am very interested to see what the fix is in the end.

[nitation]

I managed to fix the problem. A developer friend of mine said its a random error from the host. That there is nothing to do. Actually, i did nothing and all errors dissappeared.

 

Thanks guys for ur Help.

 

PFMaBiSmAd and Blade280891, Kudos to you guys.

 

[R0bb0b]

mind if I ask you what versions of apache and php you're running?

[nitation]

Php 5.2.5

Apache/1.3.41 (Unix)

[DeanWhitehouse]

When i had a problem similar to this, where setting a session timed out the script, i found out the host was upgrading the php version.

 

If you know that the code can't be causing the error, contact the host.
