Session variable problems

fogofogo · December 12th, 2005, 07:29 AM

Hello All,

I have a page that passes a session variable to another page which is then used in an if/else statement. For some reason itsa giving me error messages, and I'm not sure whats up with it.

Heres the page that creates the variable

Code:

<?php

session_start(); // start session

$_SESSION['name'] = 'sport';

?>

and heres the page with the if else statment :

Quote:

quote:<?php

session_start();

$_SESSION['name'];

//$name = 'Jester';

if ( $name == 'sport' ) { ?>

<table>stuff in here</table>

<? } else { ?>

<table>stuff in here</table>

<? } ?>

and finally - here are the error messages that I am getting :

Quote:

quote:Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at c:\wamp\www\work\hebbingo\site\test.php:11) in c:\wamp\www\work\hebbingo\site\test.php on line 13

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at c:\wamp\www\work\hebbingo\site\test.php:11) in c:\wamp\www\work\hebbingo\site\test.php on line 13

As you've guessed, I'm pretty new to this so I have probably missed something basic - any ideas?

Cheers

Fogo

There can be no output before the opening <?php delimiter before a call to session_start() is made. session_start() alters the outgoing HTTP headers (sends a cookie), and that must be done before any output from the document is made. So look for whitespace or newlines, or anything before the opening <?php delimiter.

HTH!

Regards,
Rich
