Hi,

I am virtually clueless where PHP is concenned and I was hoping someone would be able help me solve a problem with the response form that I currently have on my website.

When the form is filled in and "submit" is clicked – I get this message in the browser:

Warning: Cannot modify header information - headers already sent by (output started at /home/graphi31/public_html/response.php:12) in /home/graphi31/public_html/response.php on line 28

What is supposed to happen is that it should show a thank you page – thanks.html which is in the directory, as it has always been.

Oddly, this did not happen before, the only recent change I can think of is that I have changed my hosting to JustHost.

I'd be most grateful for any advice on how to fix this as it is driving me nuts.

Thanks in advance...

Ian.

The PHP for the response form looks like this:

<?php
// Configuration Settings
$SendFrom = "Graphic Alchemy <info@graphicalchemy.co.uk>";
$SendTo = "ian1618@googlemail.com";
$SubjectLine = "Portfolio Response";
$ThanksURL = "thanks.html"; //confirmation page

// Build Message Body from Web Form Input
foreach ($_POST as $Field=>$Value)
$MsgBody .= "$Field: $Value\n";
$MsgBody .= "\n" . @gethostbyaddr($_SERVER["REMOTE_ADDR"]) . "\n" .
$_SERVER["HTTP_USER_AGENT"];
$MsgBody = htmlspecialchars($MsgBody, ENT_NOQUOTES); //make safe

// Send E-Mail and Direct Browser to Confirmation Page
mail($SendTo, $SubjectLine, $MsgBody, "From: $SendFrom");
header("Location: $ThanksURL");
?>
