if id is primarykey, replace NULL with ' ' and try once.

use die(mysql_error()) to see whats wrong into your query.

<?php
if(isset($_POST['submit'])){
$host= "localhost";
$username= "root";
$password= "";
$db_name= "register";
$tbl_name="form";

mysql_connect("$host","$username","$password") or die(mysql_error());;
mysql_select_db("$register") or die(mysql_error());;

$fname= $_POST['fname'];
$lname =$_POST['lname'];
$eid =$_POST['eid'];
$pwd=$_POST['pwd'];
$cpwd=$_POST['cpwd'];

$sql="INSERT INTO $form (id , fname ,lname, eid , pwd,cpwd) VALUES('NULL',' $fname','$lname','$eid','$pwd','$cpwd')";
$result=mysql_query($sql) or die(mysql_error());

// close connection
mysql_close();
}

?>
