<title>Templates from a function call</title>
<para>
You can get templates from a custom function call, such as
retrieving templates from a database. You do this by first
registering your resource handler function, then creating your
function to get the template. Smarty expects your function to be of
this form: funcname($tpl_name,&amp;$tpl_source, &amp;$tpl_timestamp)
{} $tpl_name is passed into the function, and your function should
populate $tpl_source and $tpl_timestamp with the template source
and the last modified time of the template respectively.

registering your resource handler function, then creating your
function to get the template. Smarty expects your function to be of
this form: funcname($tpl_name,&amp;$tpl_source,
&amp;$tpl_timestamp[, boolean]) {} $tpl_name is passed into the
function, and your function should populate $tpl_source and
$tpl_timestamp with the template source and the last modified time
of the template respectively. The fourth parameter is a boolean
value, used for determining if the source should be returned or
not. Default this value to true in your function. If false gets
passed, you only need to return the timestamp parameter. This was
added to Smarty 1.4.6.
