I am using Simple form mail ver. 1.11.
The form is at www.bushbuckadventures.com/booking.html
It produces this error message:
"Warning: Cannot modify header information - headers already sent by (output started at /home/content/b/u/s/bushbuck/html/booking2.php:2) in /home/content/b/u/s/bushbuck/html/booking2.php on line 20"

Line 20 appears to be this: header("Location: ".$goto_after_mail);

It's supposed to direct it to thankyou.html

Otherwise the script works - it sends the right information to my email address.

Please advise. Thanks.

This error is because you output information, and then send headers.

Headers should be send before output.

Check the documentation here

The problem is before that line.

There is something printed before that.

That should be removed.

I hope we are both talking about the same script! It is posted here:
http://www.finalwebsites.com/snippets.php
The only change I made was to put my email address instead of you@yourmail.com and the name of the goto page which is thankyou.html
I don't know what change I should make to stop the error message.

The script doesn't really matters as the error is this.

There is something printed in the browser before the error.

That should be removed.

this is the part from the manual where this is about:

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

Code:
<html>
<?php
/* This will give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');
?>

So are you saying that the way I am calling the php script from my html form page is incorrect? Specifically that this line:
<form action="booking2.php" method="post" name="booking form">
is incorrect or in the wrong place?

Your last example was clear - it just doesn't relate to my situation - I don't have a single PHP/HTML file. I have an html page (booking.html) and a php file (booking2.php) that is called as the action for submitting the form. I don't see where I am sending html output before calling the function "header". What happens before the function "header" is called is that the mail is sent.

do you use echo before the header? (its also html output)

I'm using the script as posted here:
<http://www.finalwebsites.com/snippets.php?id=3>
There is no "echo".
I'm using the form as posted here:
<www.bushbuckadventures.com/booking.html>
There is no "echo" in the form.

I think there is some whitespace (which is out too!)

Thank you all for your help - I found an empty line above the "<?php" - it's fixed now and all working well.
