Question: "Please help, I'd like dynamic field names, how can I do this?!"
<HTML>
<BODY>
<?
if (isset($username)):
echo "Username is <B>" . $$username . "</B><BR>\n";
echo "Password is <B>" . $$password . "</B><BR><BR>\n";
echo "<A HREF=$PHP_SELF>Back</A>\n";
else:
$time = date("U");
echo "<FORM ACTION=\"$PHP_SELF\" METHOD=\"POST\">\n";
echo "Username: <INPUT
TYPE=\"TEXT\" NAME=\"$time" . "_u\" AUTOCOMPLETE=\"OFF\"><BR>\n";
echo "Password: <INPUT TYPE=\"PASSWORD\" NAME=\"$time" . "_p\"><BR>\n";
echo "<INPUT TYPE=\"HIDDEN\" NAME=\"username\" VALUE=\"$time" . "_u\">\n";
echo "<INPUT TYPE=\"HIDDEN\" NAME=\"password\" VALUE=\"$time" . "_p\">\n";
echo "<INPUT TYPE=\"SUBMIT\" NAME=\"Submit\" VALUE=\"Submit\">\n";
endif;
?>
</FORM>
