$_SESSION Problem state not changing

[johnnei]

Ey,

I use $_SESSION to save a login to acces some extra paged (duh -.-)...
But all variables are getting saved right but the already asigned one won't change.
I got this on top of my page:

<link href="data/style.css" rel="stylesheet" type="text/css">
<style type="text/css">
<?php 
if(!isset($_SESSION))
{
    session_start();
    $_SESSION['login'] = "true";
    echo 'NEW Session has been started<br>';
}
?>
@import url("data/style.css");
</style>
<script type="text/javascript" src="./data/lang.js"></script>

This is on index.php and through index.php all other pages are including using include(x);.

When a log-ing succeeds it will generate this:

$_SESSION['login'] = "false";
$_SESSION['id'] = "".$myrow['id'];
$_SESSION['acc'] = "".$myrow['acc'];
echo 'You have been logged in, Login Requierd: '.$_SESSION['login'].'<br>';
echo 'Account ID has been set to: '.$_SESSION['id'].'<br>';
echo 'Account Name has been set to :'.$_SESSION['acc'].'<br>';

The output of the $_SESSION's are on that area: false, 5, Johnnei.
But above that the vars are also shown and there the id and acc are set fine but login is still on true.
Why does this occur?

Edit 1: Added index.php
Edit 2: Renewed source

<?php session_start(); ?>
<link href="data/style.css" rel="stylesheet" type="text/css">
<!--<style type="text/css">
@import url("data/style.css");
</style> !-->
<script type="text/javascript" src="./data/lang.js"></script>
<center>
<?php
include("./data/common.php");
include("./module/user_data.php");
include("./data/header.php");
$op = "news";
//Get Page
if (isset($_GET['do']))
{
	$op = "" . $_GET['do'];
}
else
{
	$op = "news";
}

if($op == "reg")
{
	include("module/register.php");
}
else if($op == "news")
{
	include("module/news.php");
}
else if($op == "man")
{
	include("module/manage.php");
}
else if($op == "ins")
{
	include("module/install.php");
}
else if($op == "ser")
{
	include("module/server.php");
}
else
{
	echo 'The current page is not found in the server.';
}
?>
</center>

Gr, Johnnei

Try putting <?php session_strat(); ?> at the absolute top of the page.

I think you should take a good look at this: http://www.php.net/manual/en/intro.session.php
And pretty much everything it links to.

 

[johnnei]

Well As people dont really get me I'll add on 1st post the complete index.php. Cus on the index is almost the first thing (to avoid errors with headers etc) session_start and that is the absolute page of everything on the site.

 

[marshian]

If, and only if, I understand your problem correctly, this behaviour is normal. When you enter the page $_SESSION isn't set, not even if the client is currently associated with a session. (Sessions are not always (this is a setting in php.ini) automatically resumed.) Thus, you enter the if statement. session_start() will then either start a new session or continue a current session. Either way, $_SESSION["login"] is set to false.

First of all, you'll want to move session_start() to the absolute top of your page (even before the html-tag). Secondly, isset($_SESSION) will never give the result you want to achieve. A better way to do it would be isset($_SESSION["login"]).

PS: "almost the first thing" is not good enough, when you use headers like cookies, sessions, header(), ... you'll need to put it before any output.

 

[johnnei]

Hmm... okey I will try a few things.

Well now i put it on line 1: <?php session_start(); ?> this error occurs.. which is for me ocward but...

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/johnnei/public_html/wow/index.php:1) in /home/johnnei/public_html/wow/index.php on line 1

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/johnnei/public_html/wow/index.php:1) in /home/johnnei/public_html/wow/index.php on line 1

 

[descalzo]

You cannot have a blank line or even a single space before the

<? php session_start(); ?>

 

[johnnei]

Its on the absolute top there's nothing in-front of it anymore

 

[marshian]

There must be something in front of it somehow, can you post the entire source again?

 

[johnnei]

I archived it and included it to the post.

 

[misson]

You've got a byte order mark in your page. Save the source code as ASCII or as UTF-8 without the BOM. How you do the latter depends on your editor; check its documentation for more information.

See also "session_start() error - Not below any other ouput"

 

[johnnei]

I will have a look soon on how Dreamweaver Saves the files.. Currently really busy with everything in rl :/

 

[johnnei]

I saw that I had to uncheck a little box "Include Unicode Signature (BOM)" As un-checked I checked all files but only on index.php was that box there ... so re-uploaded all files (just to be sure ^^) but still same. I'll re-attach files.

(Sorry for double post) Just for make you guy's check the topic again :$

 

[marshian]

There's still some sort of header in the file. It's a 3 byte code: EF BB BF, but I don't know what causes it. There must be some option in Dreamweaver... (I don't have it, nor do I have any experience with it, sorry.)
What encoding are you saving the file as? Have you tried UTF-8 or ASCII?

Edit: just to confirm, the header is the same as the one in the files you uploaded earlier.
Edit again: the header does not appear in a number of other files, such as data/common.php or data/header.php, both in the old and new versions.

 

[johnnei]

Ye. I noticed that .. index.php is the ONLY file I can pick that save type... I'll post screen about howto save.

The C thing is standard maybe I have to put that to None? And Where can I see the BOM in the file (while using Hex-Editor). Is it just on top of file or somewhere else?
Edit: nvm it are the 1st 3 bytes :$
Putting the C to None still contains the BOM :/

 

[misson]

Unicode normalization affects how certain equivalent characters are saved (e.g. "\uE9" (é) vs "e\u0301" (e with combining-acute)) and has nothing to do with the BOM. From the screenshot, the option that should affect the presence of the BOM is (surprise, surprise) "Include Unicode Signature (BOM)".

 

[johnnei]

From the screenshot, the option that should affect the presence of the BOM is (surprise, surprise) "Include Unicode Signature (BOM)".

Oh my god! Your ****ting me?... I not that smart.. but he.. I'm not dumb also -.-
I unchecked it made it overwrite it and its still there...

 

[misson]

Wow, sarcasm. That's original. My point is the only setting that affects the presence of the BOM is the one that mentions the BOM. Try changing it in the page properties.

 

[johnnei]

The error is gone now
Tnx Now I can start fixing the pages ^^
