session error

[AviNahum]

hey,

i have this code:

<?php

//--------------------------------
// Starting our session
//--------------------------------

session_start();

//--------------------------------
// load database connection
//--------------------------------

require "connect.php";

//--------------------------------
// Make some checks if the admin
// Are loged in
//--------------------------------

if ( ! isset($_SESSION['admin']) || ! isset($_SESSION['name']) )
{
require "login.php";
die();
}

if ( $_SESSION['admin'] != 1 || $_SESSION['name'] == "" )
{
require "login.php";
die();
}

if ( $core->input['act'] == logout )
{
unset($_SESSION['admin']);
unset($_SESSION['name']);
session_destroy();

header('Location: index.php');
}

?>

 

im trying to set a simple session, but i getting this error:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php:1) in /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php on line 7

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php:1) in /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php on line 7

 

but as you can see i put the session start in the top of the file...

 

any ideas?

 

Thanks!

what about connect.php or login.php?  are they trying to call session() again?  are they outputting anything?

What is on those lines that the error references in the admin file?

 

Also the last clause (logout) your not exiting the script after that last header call...

The OUTPUT is on line 1 of that file. Either you have an actual character in the file before the <?php tag or the output is the BOM characters that your editor saved at the start of the file. See the last post in this sticky thread - http://www.phpfreaks.com/forums/index.php/topic,37442.0.html

I believe the code that aviavi has posted is the Admin file.

This is usualy fixed (in my limited experience) by removing all blank lines prior to the entry:

<?php
//--------------------------------
// Starting our session
//--------------------------------
session_start();

//--------------------------------
// load database connection
//--------------------------------
require "connect.php";

 

This would prevent the issue that PFMaBiSmAd was talking about (the possibility of hidden characters)

 

The other possibility is too look at the login.php and make sure it doesn't have any headers, as you have already sent them in the admin file.

the file i posted is admin.php.

the login and connect files are fine...

 

this error appeared only after i edited this file and saved it...

hm. are you on Windows? you may have a character encoding issue and there is actually an "invisible" character before <?php

[AviNahum]

so what can i do? i wrote this file on linux but but know im on windows...

[PFMaBiSmAd]

If the problem are the BOM characters that your editor is placing at the start of the file, the solution is to save the file without the BOM characters. If your programming editor does not have an option to change the file encoding to UTF-8 without BOM or to ANSI encoding, you will need to use a better editor.

alright, thanks everyone... solved!
