FormToEmail is not validating the fields

Question

Hi all
iam newto contact form n php downloaded FormToEmail.php from dreamweaverspot.
The issue is email is working even if i submit blank form.
my page link http://fagencomputers.com/contact.html.
Can anyone help me how to validate the form using php?
thanks in advance,
naveen
here is the php script
<?php
$my_email = "[email protected]";
Enter the continue link to offer the user after the form is sent.  If you do not change this, your visitor will be given a continue link to your homepage.
If you do change it, remove the "/" symbol below and replace with the name of the page to link to, eg: "mypage.htm" or "http://www.elsewhere.com/page.htm"
$continue = "/";
Step 3:
Save this file (FormToEmail.php) and upload it together with your webpage containing the form to your webspace.  IMPORTANT - The file name is case sensitive!  You must save it exactly as it is named above!  Do not put this script in your cgi-bin directory (folder) it may not work from there.
THAT'S IT, FINISHED!
You do not need to make any changes below this line.
$errors = array();
// Remove $_COOKIE elements from $_REQUEST.
if(count($_COOKIE)){foreach(array_keys($_COOKIE) as $value){unset($_REQUEST[$value]);}}
// Check all fields for an email header.
function recursive_array_check_header($element_value)
global $set;
if(!is_array($element_value)){if(preg_match("/(%0A|%0D|\n+|\r+)(content-type:|to:|cc:|bcc: )/i",$element_value)){$set = 1;}}
else
foreach($element_value as $value){if($set){break;} recursive_array_check_header($value);}
recursive_array_check_header($_REQUEST);
if($set){$errors[] = "You cannot send an email header";}
unset($set);
// Validate email field.
if(isset($_REQUEST['email']) && !empty($_REQUEST['email']))
if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or a colon";}
$_REQUEST['email'] = trim($_REQUEST['email']);
if(substr_count($_REQUEST['email'],"@") != 1 || stristr($_REQUEST['email']," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST['email']);if(empty($exploded_email[0]) || strlen($exploded_email[0]) > 64 || empty($exploded_email[1])){$errors[] = "Email address is invalid";}else{if(substr_count($exploded_email[1],".") == 0){$errors[] = "Email address is invalid";}else{$exploded_domain = explode(".",$exploded_email[1]);if(in_array("",$exploded_domain)){$errors[] = "Email address is invalid";}else{foreach($exploded_domain as $value){if(strlen($value) > 63 || !preg_match('/^[a-z0-9-]+$/i',$value)){$errors[] = "Email address is invalid"; break;}}}}}}
// Check referrer is from same site.
if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$errors[] = "You must enable referrer logging to use the form";}
// Check for a blank form.

global $set;
if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}}
else
foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value);}
recursive_array_check_blank($_REQUEST);
if(!$set){$errors[] = "You cannot send a blank form";}
unset($set);
// Display any errors and exit if errors exist.
if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;}
if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");}
// Build message.
function build_message($request_input){if(!isset($message_output)){$message_output ="";}if(!is_array($request_input)){$message_output = $request_input;}else{foreach($request_input as $key => $value){if(!empty($value)){if(!is_numeric($key)){$message_output .= str_replace("_"," ",ucfirst($key)).": ".build_message($value).PHP_EOL.PHP_EOL;}else{$message_output .= build_message($value).", ";}}}}return rtrim($message_output,", ");}
