Header problem - again...

headers already sent

[lorax]

I understand the basics of headers but here's a problem that doesn't fit with what I thought I knew.

Page 1: 2 forms with 1 select box each. The option values are page names (page1.php). Javascript is used to submit the form using onChange event. Form actions point to a seperate page that has the following code:

Page 2:
<?php
header("Location: /dir1/dir2/$pn.php");
exit;
?>

where $pn is the value of the <option> selected.

There's no HTML on this page.

So why am I getting "Headers already sent"?

If it' page 2 that's throwing up the error, is that really how it looks or is there any include/requires' in that file?

Sometime having a blank line after?> at the end of an include will cause that kind of problem...

DOH!

I found the error - a single space in front of my <?php - well at least I only spent 30 minutes on this one.

Thanks Nick.

Anytime, I've spent hour upon hour pouring over code only to find similar daft mistakes. It's those little ones that are the toughest... ;-)
