Hey again guys.
On my php advert sys, I am getting a weird error. Well, I think its weird, anyway!

Right, what happens is, the php scripts won't redirect using the 'header ("Location: blah.php");' code.

This is happening in a few of my scripts. For example, on a forgot password? script I have done, what I want is, if someone has forgotten their password, they follow the link to:
forgotpw.php?forgot=1

So, then, what I am doing with php, is saying that if the 'forgot=1' isn't present, they haven't followed a link, and so it redirects them back to the login page.

The error I get is:

Warning: Cannot add header information - headers already sent by (output started at C:/PROGRAMMING/eliter/advertsys/forgotpw.php:17) in C:/PROGRAMMING/eliter/advertsys/forgotpw.php on line 39

I am getting this in more than one script..

Anyone know what this could be?
Cheers.

YOu cannot have any output above the header() call. That means if you are printing anything or you have blank spaces or html tags above your opening <? tag you will get this error.

} elseif (!$forgot) {

header ("Location: $advertiserlogin");

}

so is there anything wrong with that then?

(I do have a few openings and closings of <?php ?> above that though)
cheers

Yes you cannot have those any opening and closings of <? ?> above that so I assume you have something like
<html>
<head>
</head>
<body>
<?
} elseif (!$forgot) {

header ("Location: $advertiserlogin");

}

?>

YOU cannot have any ouput above the header() call This will cause your error.

As will
<?
//Some code
?>

<?
} elseif (!$forgot) {

header ("Location: $advertiserlogin");

}
?>
