this is a contact form code which works and when I submit the message, it says thanks it was sent successfully, but unfortunately I have not got any messages. I use it on wordpress on local host.

what should I change in order to get the messages?? any help please

<?php
if(isset($_POST['submitted'])) {
    if(trim($_POST['contactName']) === '') {
        $nameError = 'Please enter your name.';
        $hasError = true;
    } else {
        $name = trim($_POST['contactName']);
    }


    if(trim($_POST['email']) === '')  {
        $emailError = 'Please enter your email address.';
        $hasError = true;
    } else if (!preg_match("/^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+.[a-z]{2,4}$/i", trim($_POST['email']))) {
        $emailError = 'You entered an invalid email address.';
        $hasError = true;
    } else {
        $email = trim($_POST['email']);
    }


    if(trim($_POST['subject']) === '') {
        $subjectError = 'Please enter a subject.';
        $hasError = true;
    } else {
        $subject = trim($_POST['subject']);
    }


    if(trim($_POST['comments']) === '') {
        $commentError = 'Please enter a message.';
        $hasError = true;
    } else {
        if(function_exists('stripslashes')) {
            $comments = stripslashes(trim($_POST['comments']));
        } else {
            $comments = trim($_POST['comments']);
        }
    }

    if(!isset($hasError)) {
        $emailTo = get_option('tz_email');
        if (!isset($emailTo) || ($emailTo == '') ){
            $emailTo = get_option('admin_email');
        }
        $subject = '[PHP Snippets] From '.$name;
        $body = "Name: $name nnEmail: $email nnComments: $comments";
        $headers = 'From: '.$name.' <'.$emailTo.'>' . "rn" . 'Reply-To: ' . $email;

        wp_mail($emailTo, $subject, $body, $headers);
        $emailSent = true;
    }

} ?>
