sending email to a user

[LBC]

Hey,

I cannot seem to get that sending an email to a user right.
I'm using this form:

<pre>

Code:

<?php
        if (isset($_POST["submit"])) {

        $name = $_POST['name'];
        $email = $_POST['email'];
        $message = $_POST['message'];
        $human = intval($_POST['human']);
        $from = $user->data()->email['email'];
        $to = $thatUser->email;
        $subject = 'Message from Local Positivity Finder';
        
        $body ="From: $name\n E-Mail: $email\n Message: $message\n";

        // Check if name has been entered
        if (!$_POST['name']) {
            $errName = 'Please enter your name';
        }
        
        // Check if email has been entered and is valid
        if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
            $errEmail = 'Please enter a valid email address';
        }
        
        //Check if message has been entered
        if (!$_POST['message']) {
            $errMessage = 'Please enter your message';
        }
        //Check if simple anti-bot test is correct
        if ($human !== 5) {
            $errHuman = 'Your anti-spam is incorrect';
        }
        
        // If there are no errors, send the email
        if (!$errName && !$errEmail && !$errMessage && !$errHuman) {
        if (mail ($to, $subject, $body)) {
            Redirect::to($us_url_root.'users/contact_success.php');
        } else {
            Redirect::to($us_url_root.'users/contact_error.php');
        }
        }
}

?>

</pre>


Any idea what im doing wrong?
