Assigning the values of superglobals ($_GET, $_POST, $_REQUEST, $_SESSION, $_COOKIE, $_SERVER, $_ENV) is redundant. You can access any of these within a template through the {$smarty} variable, in your case {$smarty.post.do}.

The following is true for Smarty3:

The third argument to assign() is the nocache flag. For more information on this, see cacheability of variables. If this actually solved your problem, your real problem lies with your caching. You likely have $smarty->caching = true; set, in which case the template is not rendered on every invocation, but read from cache if possible.

If you need further assistance, you may want to elaborate on the failing cases.

Aside from that, please have a close look at the other comments suggesting $_POST['do'] over $_POST[do] and the use of isset() or empty() where applicable.

You should check or set a default value:

<?php 
//Check it or set default for $do
$do=(isset($_POST['do']))?$_POST['do']:'';

//Assign the $smarty var with $do
$smarty->assign("akakak", $do);
?>
