header???

[alvinshaffer]

I get this error

Warning: Cannot modify header information - headers already sent by (output started at

any help??

[Xoid]

this error occurs if you already send information to the browser, e.g.

<?php
// This would generate an error

print "SENDING SOMETHING TO THE WEBPAGE";
header("location: apage.php");
exit();
?>

<?php
// This won't generate an error
header("location: apage.php");
exit();
?>

Hope this helps!

One more error. Any help with this one

Warning: session_destroy(): Trying to destroy uninitialized session in

[Xoid]

could be a number of problems, have you called session_start();

[alvinshaffer]

session_start();

$old_user = $HTTP_SESSION_VARS['valid_user']; // store to test if they were logged in
unset($HTTP_SESSION_VARS['valid_user']);
session_destroy();
$old_admin = $HTTP_SESSION_VARS['admin_user']; // store to test if they were logged in
unset($HTTP_SESSION_VARS['admin_user']);
session_destroy();

[Xoid]

try this:

<?php
session_start();

$old_user = @$HTTP_SESSION_VARS['valid_user'];
unset($HTTP_SESSION_VARS['valid_user']);

$old_admin = @$HTTP_SESSION_VARS['admin_user'];
unset($HTTP_SESSION_VARS['admin_user']);

session_destroy();
?>

HTH.
