| You have to write a registered function or function plugin to do this job if you really have to modify the session from within the template. |

do that in PHP (business logic). otherwise write a plugin to assign it, as session vars are read-only in the template. But you really should handle this in PHP and just assign presentational elements in-template. example:
php:
| Code: | if($_SESSION['popup']) {
$smarty->assign('is_popup',true);
$_SESSION['popup'] = false;
} |
template:
| Code: | {if $is_popup}
...
{/if} |
Here you see the template deals with presentation, and not the underlying business logic (ie. reading/writing session vars) |
