Can do something like this (substitute your variables of course)

 

if (isset($_POST['uname']) || isset($_POST['pword']))

{

  //submitted, check values

  if (empty($_POST['uname'])) { die ("Error: Enter a username"); }

  if (empty($_POST['pword'])) { die ("Error: Enter a password"); }

}

My advice then is to learn PHP or hire someone to do it for you.
