Form shows success message but no email is received - php

Question

I have a Bootstrap 3 form that displays the success message: "Your message has been sent" but I don't receive any emails. Not even in my spam/junk folder. It validates properly but no email is sent. Here's the PHP code. Please help!
PHP
<?php
// check if fields passed are empty
if(empty($_POST['firstname']) ||
empty($_POST['lastname']) ||
empty($_POST['address']) ||
empty($_POST['address2']) ||
empty($_POST['city']) ||
empty($_POST['state_province']) ||
empty($_POST['country']) ||
empty($_POST['zip']) ||
empty($_POST['phone']) ||
empty($_POST['email']) ||
empty($_POST['checkbox']) ||
empty($_POST['comment']) ||
{
echo "No arguments Provided!";
return false;
}
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$address = $_POST['address'];
$address2 = $_POST['address2'];
$city = $_POST['city'];
$state_province = $_POST['state_province'];
$country = $_POST['country'];
$zip = $_POST['zip'];
$phone = $_POST['phone'];
$email_address = $_POST['email'];
$checkbox = $_POST['checkbox'];
$message = $_POST['comment'];
// create email body and send it
$to = 'email#example.com'; // put your email
$email_subject = "Contact form submitted by: $firstname";
$email_body = "You have received a new message. \n\n".
"Here are the details:\n \nFirst Name: $firstname \n Last Name: $lastname\n Address: $address\n Address2: $address2\n City: $city\n State/Province: $state_province\n Country: $country\n zip: $zip\n Phone: $phone\n Email: $email_address\n Checkbox: $checkbox\n Message: \n $message";
$headers = "From: $email_address\n";
$headers = "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
return true;
?>

UPDATE 8:50PM 03/09
I uploaded this to a different host and now, when I submit the form I'm getting an error :"Message cannot be sent!"

Answer 1

you are sending the email to "email#example.com"
Probably try sending it to your email address, by changing the $to variable.
Also change the headers. From This
$headers = "From: $email_address\n";
$headers = "Reply-To: $email_address";
To:
$headers = "From: $email_address\n";
$headers .= "Reply-To: $email_address";
note the .= on the second line, this means add the string onto headers vs replacing the content of the variable.
And maybe change this:
mail($to,$email_subject,$email_body,$headers);
return true;
to
return mail($to,$email_subject,$email_body,$headers); // will return true on success send, or false if it failed to send.
