For security reasons I’ve added a security input/question into my form.

Something like:

**"Please type the word ‘puppy’ into the space below:  
\_\_\_\_\_\_\_\_\_\_\_\_"**

I was able to get help [validating it in JavaScript](http://www.kirupa.com/forum/showthread.php?t=303793), but I realized I also need it validated with php incase javascript is disabled.

Can someone help me work that into my exhisting php code?

```php

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

    $subject = "Contact Message From XXXXX.com";
    $from = 'From: ' . $_POST["name"] . "
";
    $to = "adam@XXXXX.com";
    
	$message = "CONTACT MESSAGE FROM XXXXX.COM" . "

"; 
    $message .= "Name:
" . $_POST["name"] . "

";
	$message .= "Email:
" . $_POST["email"] ."

";
	$message .= "Comments:
". $_POST["comments"];

    mail($to, $subject, $message, $from);
    
}
?> 

```

Thanks!
