formmailer with if-inquiry

[shayenne]

Dear all,

I have a simple formmailer. The datas are voluntarily.
If the people write down their address I would like to have the formular by email. Otherwise when the formmailer has no datas
I don't want an email.

<?php
$admin= '[e-mail]';
$subject= 'Registrierung Rechenprogramme';
$message= 'Nachrichten an '.$admin.' von '.$email.":\n";
foreach($HTTP_POST_VARS as $name=> $value) {
$message.= "$name:$value\n";
}
if ($message != ""){
mail($admin, $subject, $message, "From: $email");
}
header('Location: [url]http://[/url]'.getenv('HTTP_HOST').'/enev/rechenprogramm_download.html');
?>

Unfortunately the if-inquiry doesn't work at this place. All emails come in. Has somebody an idea???

Thanks.

According to your sample code, you've assigned a value to $message, so when you do your "if" check, it will always be TRUE according to your setup.

Maybe change your "if" check to something else like:

if ($email) {
// send an e-mail
}

where $email is the e-mail address supplied by the visitor. This way, if the visitor hasn't supplied a (valid) e-mail address, you will not receive any notifications via e-mail.
