Closing the window in an onsubmit() handler seems untidy.
For example this precludes the script which receives the
form from returning an error message.

What I do is have the server-side script write a block of
JavaScript which in turn closes the window.  Here's a PHP
snippet that may offer some ideas:

<script LANGUAGE="JavaScript">
<?php
  if ($errmsg) {
    echo "window.alert('$errmsg')\n";
    echo "window.back()\n"; // redisplay the form
  } else {
    echo "opener.document.forms[0].submit()\n";
    echo "window.close()\n";
  }
?>
</script>
