I have the same type of problem

I'm trying to use header in a function when it is called

Code: Select all

function accessGranted( $name ){
            header( 'Location: logged.php');
            exit();   
}

but I get this error,

Code: Select all

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/lab6/login.php:8) in /var/www/html/lab6/login.php on line 101


I've found a lot online about this error, and even found something that said if you use any html at al it won't work, so I took all the html out.. but now, I still get this error[/code]

exactly.. Im gettin same problem.. thats why im wondering if HEADER is the wrong thing to use?

Well, the headers are part of the negotiations between server and browser, so you have to put them before any html (even the doctype) and before any echo or other output.
Your error message clearly states "output already started".

I forgot: If you have to print the redirect somewhere "in the middle" of the page use this:

Code: Select all

<SCRIPT LANGUAGE="JavaScript">
   <!--
      location.replace("<?=$other_page?>");
   //-->
</SCRIPT>
<NOSCRIPT>
   <META HTTP-EQUIV="Refresh" CONTENT="<?=$other_page?>">
</NOSCRIPT>

Thx Peocos,
I took out the DocType and it works, If I put the doctype at end of the page so that I can try to validate it, should that still work?

A common problem I find when adding headers is if there is a whitespace before the starting PHP tag.
For example:

Code: Select all

<?php

header('Location: http://www.php.net/');
?>


This whitespace is counts as an output and is sent to the browser, thus generating the header error message.
