Need help to make it validateable

Hello guys,

I've generated form from phpform generator.

Here is my process file:

<?php
include("global.inc.php");
$errors=0;
$error="The following errors occured while processing your form input.<ul>";
pt_register('POST','name');
pt_register('POST','email');
pt_register('POST','title');
pt_register('POST','keywords');
pt_register('POST','description');
$description=preg_replace("/(\015\012)|(\015)|(\012)/","&nbsp;<br />", $description);pt_register('POST','reciprocal');



if($name=="" || $email=="" || $title=="" || $keywords=="" || $description=="" || $reciprocal==""){
$errors=1;
$error.="<li>You did not enter one or more of the required fields. Please go back and try again.";
}

if(!eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*" ."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email)){
$error.="<li>Invalid email address entered";
$errors=1;
}
if($errors==1) echo $error;
else{
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));
$message="name: ".$name."
email: ".$email."
title: ".$title."
keywords: ".$keywords."
description: ".$description."
reciprocal: ".$reciprocal."
";
$message = stripslashes($message);
mail("rak2006@gmail.com","New directory submitted",$message,"From: myRank");

?>


<table width="70%" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#006600">
  <tr>
    <td bgcolor="#eeffee"><h2 align="center">Thank you <?php echo $name; ?>!</h2>
    <p align="center">We've received your directory submission... <br />
    Please be patient, we might contact you within 24-72 hours of submission.<br />
      <br />
      <br />
    </p>
    <div align="left"><br />
    </div>
    &nbsp;<a href="http://<?=$_SERVER['HTTP_HOST'];?>/"><font color="#006600">&laquo; Back to homepage </font></a></td>
  </tr>
</table>
<?php 
}
?>

PHP:

Here is a reciprocal link checker:

	$siteurl = "http://fonebuzz.net/"; // this is the webpage the backlink should be found on
	
	if (backlinkCheck($siteurl, $reciprocal)) {
		$abcc="";
	} else {
		$corr="Reciprocal is wrong";
	}
	
	function backlinkCheck($siteurl, $reciprocal) {
	$arrText = file($siteurl);
	for ($i=0; $i<count($arrText); $i++) {
		$text = $text . $arrText[$i];
	}
	if (eregi($reciprocal, $text)) {
		return true; // set true if there is a backlink
	} else {
		echo $abcc; // set false if backlink is missing
	}
}

PHP:

i want to connect that reciprocal variable with above form, so it could pass the url first before sending the form at my email.


any help?
