Recommend us to a friend - email takes friend to wrong page

[Steph84]

Hello - I know very little PHP/Javascript so I am having a problem that I hope is easily fixable.

I installed a "recommend to a friend" tool to my website and have managed to solve a few issues I have had with it, however there is one issue I can't work out how to solve.

The email that is sent to the 'friend' displays a link to the /siterecommender/recommend.popup.php page (that sent the email). I want it to take them to the home page instead.

The php is as follows:

$sitename = '1-2-1 Music Tuition'; // Name of your site.

$url = $_SERVER['HTTP_REFERER']; // Web address for your site.

$webmasterEmail = 'info@1-2-1music.co.uk'; // Your email address.

$receiveNotifications = 1; // 0=no, 1=yes. If yes, you will be notified of the recipients and the message.

$errorstyleclass = 'error'; // The class that specifies the CSS error color.

$numberofrecipients = 4; // Number of recipient email address fields to be displayed.

$emailsubject = 'Music tuition recommendation from [name] ([email])'; //Email subject line.

$emailmessage = "Hello

[name] thought you would like to visit the following site:

[url]

1-2-1 Music Tuition provide acoustic and electric guitar, bass guitar and drum tuition at competitive rates. They are based in a professional recording studio in Sheffield city centre. New pupils can get their first lesson for only £5. See their website for more information."; // Message in email body. 

$mailsent = false; 
$errormessages = array(); 
$errorfields = array(); 

if(count($_POST) > 0) { 
if(get_magic_quotes_gpc()) $_POST = strip_magic_quotes($_POST); 

if(empty($_POST['name'])) { 
$errormessages[] = 'Please enter your name.'; 
$errorfields[] = 'name'; 
} 

if(empty($_POST['email'])) { 
$errormessages[] = 'Please enter your email address.'; 
$errorfields[] = 'email'; 
} else { 
if(!eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $_POST['email'])) { 
$errormessages[] = 'Please enter a proper email address for yourself.'; 
$errorfields[] = 'email'; 
} 
} 

for($i=1, $count=count($_POST['to']); $i<=$count; $i++) { 
if(empty($_POST['to'][$i])) unset($_POST['to'][$i]); 
} 

if(empty($_POST['to'])) { 
$errormessages[] = 'Please enter at least one friend's email address.'; 
$errorfields[] = 'to[1]'; 
} else { 
foreach($_POST['to'] as $key=>$value) { 
if(!empty($value)) { 
if(!eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $value)) { 
$errormessages[] = 'Please enter email address #' . $key . ' proper.'; 
$errorfields[] = "to[$key]"; 
} 
} 
} 
} 

// Now if there are no errors, send the message. 
if(empty($errormessages)) { 
$emailsubject = str_replace('[name]', $_POST['name'], $emailsubject); 
$emailsubject = str_replace('[email]', $_POST['email'], $emailsubject); 
$emailmessage = str_replace('[name]', $_POST['name'], $emailmessage); 
$emailmessage = str_replace('[url]', $url, $emailmessage); 
$emailmessage .= "\r\n\n" . 
$_POST['message'] . 
"\n\n\n\nNote: This message was not sent unsolicited. It was sent through a form located at $url. " . 
"If you believe this message was received on error, please disregard it."; 
$emailheader = "From: " . $_POST['email'] . "\r\n" . 
"Reply-To: " . $_POST['email'] . "\r\n" . 
"X-Mailer: GateQuest php Site Recommender\r\n"; 

$sent = array(); 
foreach($_POST['to'] as $key=>$value) { 
if(mail($value, $emailsubject, $emailmessage, $emailheader)) { 
$sent[] = $value; 
} 
} 
$failed = array_diff($_POST['to'], $sent); 
$mailsent = true; 

if($receiveNotifications) { 
$subject = 'Someone recommended your site'; 
$message = 'This is a message to tell you that ' . $_POST['name'] . ' (' . $_POST['email'] .')' . 
' sent a website recommendation to ' . implode(', ', $sent) . 
"\n\nMessage: " . $_POST['message']; 
$headers = 'From: ' . $webmasterEmail . "\r\n" . 
'X-Mailer: GateQuest php Site Recommender'; 
@mail($webmasterEmail, $subject, $message, $headers); 
} 
} 
} 

?> 

(there is more code that follows but it is to do with the form that sends the email, not the email itself).

It's clearly something to do with $url but beyond that I am not sure. How do I get the email to show a link to the home page, rather than the page that sent the email?

Any help will be much appreciated.

Thanks. Steph
