isset

Hi I am a building a guestbook as a course of my learning of PHP. I have a page, on wich theree are some input boxes, on th enext page the data typet in those boxes is putet in to a database. I would like to check if there are nay empty input boxes, and if there are the user would get the sam form back and on the top it would say : Please fill the empty text boxes, and in the boxes would be the data that he has puet in. And I dount know how to include that in to this code : <? include ("../head.php"); MYSQL_CONNECT("localhost", "user", "password" ) or

              die(MYSQL_ERROR() . "napaka1");

MYSQL_SELECT_DB("knjiga") or

               die(MYSQL_ERROR() . "napaka2");

$ime = strip_tags($_POST[ime]); $naslov = strip_tags($_POST[naslov]); $email = strip_tags($_POST[email]); $url = strip_tags($_POST[url]); $kom = strip_tags($_POST[kom]); if ($_POST["submit"]) {

    $query = "insert into knjiga
    (ime, naslov, email, url, komentarji) values

('$ime','$naslov','$email','$url','$kom')"

          ;

          MYSQL_QUERY($query) or
          die(MYSQL_ERROR() . "napaka3");

?> <h2>Thanx</h2> <h2><a href="poglej.php">Poglej knjigo gostov!</a> <? } else {

    include("index.php");
