tid-bit of information :

> This question is so basic, but I have no idea where to look for an

> ANyway, I need to change the code so that, when there are no row returned

> Now, the way I would have done this before using smarty would be to check
> the number of records, and if there were none, I would display the
> message, otherwise, I would loop through and display the results,
>
> However, I know one of the points of smarty is to keep code out of the

> Any help directing me to an example or whatever would be helpful.

> Here is what is going on right now in the code:

> (in the PHP page)
> $events = $db->getAll($sql_events, DB_FETCHMODE_ASSOC);
> $tpl->assign("events",$events);
>
> (in the template page)
> {section name=id loop=$events}

According to this page
http://smarty.php.net/manual/en/language.function.if.php you should be able
to do something like.....
{ if is_array ( $events ) }
do smarty stuff
{ /if }
