Answer 1

set the action in the HTML form to:

contact-form-handler.php

like:

<form method="POST" name="contactform" action="contact-form-handler.php"> 

UPDATE 1: And check this:

Change

$email_subject = "Contact form submission: $name";

to

$email_subject = "Contact form submission:" . $name;

UPDATE 2: And this also:

$headers = "From: $myemail\n"; 
$headers .= "Reply-To: $email_address";

to:

$headers = "From: " . $myemail . "\n"; 
$headers .= "Reply-To:" . $email_address;

UPDATE 3:

You validate the E-mail address $email_address but never use it.

Answer 2

一定要检查动作中的文件名！！
