    This is usually done via a server-side script. Let's say script.php

    <form action = "script.php"...

    Or make sure that

    <form action = ""...

    Is specified in from on a .PHP page itself.

    When the script refreshes, the values will be available via following array:

        $a = $_POST["getdobcval"];  // Submitted as POST
        $b = $_GET["getdobcval"];    // Submitted as GET

    Or alternatively you can receive it regardless of how it was submitted by:

        $c = $_REQUEST["getdobcval"];
