Help! My form which requires email and zip code is arriving without data. How is that possible?

Question

An HTML form design with Dreamweaver CS5 requires the zip code and email to be entered prior to Submitting the form. We tested the form prior to going live and it worked great. The Zip Code and Email are required entries. Today, we received our first completed form from a customer and it worked and looked great. The problem is ... we have also received two forms that are blank. No data results at all; no email or zip code either. I don't know how this can be. The form cannot Submit unless the email and zip code are present.
Suggestions?
This is the webpage that has the form (scroll toward the bottom to view it).

The PHP code is:
<?php
//--------------------------Set these paramaters--------------------------
// Subject of email sent to you.
$subject = 'Trigger Prop Contact Form';
// Your email address. This is where the form information will be sent.
$emailadd = '[email protected]';
// Where to redirect after form is processed.
$url = 'http://www.catchaghostparanormalequipment.com/confirmation.html';
// Makes all fields required. If set to '1' no field can not be empty. If set to '0' any or all fields can be empty.
$req = '0';
// --------------------------Do not edit below this line--------------------------
$text = "Results from form:\n\n";
$space = ' ';
$line = '';
foreach ($_POST as $key => $value)
if ($req == '1')
if ($value == '')
{echo "$key is empty";die;}
$j = strlen($key);
if ($j >= 40)
{echo "Name of form element $key cannot be longer than 40 characters";die;}
$j = 40 - $j;
for ($i = 1; $i <= $j; $i++)
{$space .= ' ';}
$value = str_replace('\n', "$line", $value);
$conc = "{$key}:$space{$value}$line";
$text .= $conc;
$space = ' ';
mail($emailadd, $subject, $text, 'From: '.$emailadd.'');
echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';
?>
