couldnot modify header information

Question

I got an "Warning: Cannot modify header information - headers already sent (output started at process_contact.php:5) in (/process_contact.php on line 147 )" while using mail() in php for sending an mail to multiple user.

    $from = "test@gmail.com";
    $adminmessage="You have received an email from ".$_POST['email'].
    $to = "test1@gmail.com";
    $subject = "Email Received for an Order";

`$adminmessage="You have received an email from ".$_POST['email'].` Note the `.` at the end. I think you meant a `;` — tigrang, May 10 '12 at 07:59

You cannot send header information after you have already echoed something. See PHP output buffering for information on how to get around this.

Drop this and it should work:

echo "Mail Sent.";

I had already tried that and that hadnot worked too.... – Yogs May 10 '12 at 08:09
check for any whitespace, specially after the closing php tag, you could just omit the closing tag to be sure. – gunnx May 10 '12 at 08:25

echo "Mail Sent.";
header('Location: reservation.php?sentok');

That ^

In any case, it doesn't make sense anyway to echo something then directly redirect. You could instead output Mail Sent at reservation.php

if(isset($_GET['sentok'])) echo 'Mail Sent.';

EDIT:

I think you got a syntax error there as pointed by your error message:

$adminmessage="You have received an email from ".$_POST['email']. // <-- this
$to = "test1@gmail.com";

This gives me an Undefined Variable notice in my local setup, which in turns stopping you from calling header() as that notice is counted as an output by php.

You have an echo statement before the header() call, that will cause headers to be sent. You must not output anything before a header()
