Re: [PHP] flushing formdata / flushing the client to prevent resubmitting formdata ? From: dgw <email protected>
Date: 07/12/00

Its easy, take this as an example (its called index.php):

<HTML>
<BODY>

<?
if ($newrecord) {
    mysql_query( "......" );
    Header( "index.php" );
}
?>

<FORM>
<INPUT NAME=newrecord>
<INPUT TYPE=submit>
</FORM>

</BODY>
</HTML>

The header line in the middle makes the page load again without the
$newrecord variable. That way, if the user refreshes, it'll simply load
index.php again.

Hope im right :-)

Regards,

David Garcia Watkins
