?>

<input type="hidden" name="ip" value="<?php echo $ipi ?>" />
<input type="hidden" name="httpref" value="<?php echo $httprefi ?>" />
<input type="hidden" name="httpagent" value="<?php echo $httpagenti ?>" />

<br />
</form>
    PHP:

    and this is from sendemail.php :

    
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>Sendemail Script</title>
</head>

<?php

$ip = $_POST['ip']; 
$httpref = $_POST['httpref']; 
$httpagent = $_POST['httpagent']; 
$visitor = $_POST['visitor']; 
$visitormail = $_POST['visitormail']; 
$notes = $_POST['notes'];
$attn = $_POST['attn'];

if(!$visitormail == "" && (!strstr($visitormail,"@") || !strstr($visitormail,"."))) 
{
echo "<h2>Use Back - Enter valid e-mail</h2>\n"; 
$badinput = "<h2>Feedback was NOT submitted</h2>\n";
echo $badinput;
die ("Go back! ! ");
}

if(empty($visitor) || empty($visitormail) || empty($notes )) {
echo "<h2>Use Back - fill in all fields</h2>\n";
die ("Use back! ! "); 
}

$todayis = date("l, F j, Y, g:i a") ;

$attn = $attn ; 
$subject = $attn; 

$notes = stripcslashes($notes); 

$message = " $todayis [EST] \n
Attention: $attn \n
Message: $notes \n 
From: $visitor ($visitormail)\n
Additional Info : IP = $ip \n
Browser Info: $httpagent \n
Referral : $httpref \n
";

$from = "From: $visitormail\r\n";


mail("home@mysite.com", $subject, $message, $from);

?>

    Hi,
    To redirect auto to the index.php after submitting the mail, replace this line in your script:
    mail("home@mysite.com", $subject, $message, $from);
    Code (markup):
    With this code:
    if(mail("home@mysite.com", $subject, $message, $from)) header('Location: /index.php');
    Code (markup):
    About the captcha, it is needed to many changes, adding session, new field in form, cheching the value of session with the value added in form, ...

    Hi,
    Sorry, the header() function works only if there is not any output to browser (like echo, or html code) before the line where it is added.
    Try with this code:
    if(mail("home@mysite.com", $subject, $message, $from)) echo '<meta http-equiv="refresh" content="0;url=/index.php" />';
    Code (markup):
    which outputs a meta html tag that force refresh to index.php.

    works!,but,

    now,when i receive the email by the test i have done,i know before when i was getting the email in subject it say something ,now it does not say anything,
    is that has anything to do with the code provided?

    also,if possible after submitting some how to say "email sent ,we will reply within 24 hours or less!"
    and then 5 sec later to redirect to main page?!
    can that be added?

    thanks,friend!

    Normally, that code should not affect the email, because it is executed after the email is send.
    To make the redirect after 5 sec., try this:
    if(mail("home@mysite.com", $subject, $message, $from)) echo '<meta http-equiv="refresh" content="5;url=/index.php" />email sent ,we will reply within 24 hours or less!';
    Code (markup):

    works,now,except for the subject line,i guess because the php code is not there in contact.php form.

    thank you.
