Custom resources

Hi, hoping someone can help me with this. I am working on a
custom resource
handler must be missing something obvious...? Why is this
giving me this
error: "Warning: Smarty error: unable to read
resource: "db:blah" in
C:\htdocs\cms\libs\Smarty.class.php on line 1095"?
 

<?php
 
require_once('libs/Smarty.class.php');
 
$smarty = new Smarty;
 
function db_source($tpl_name, &$tpl_source,
&$smarty_obj) {
     $tpl_source = "You asked for $tpl_name.";
     return true;
}
 
function db_timestamp($tpl_name, &$tpl_timestamp,
&$smarty_obj) {
     return false;          // it's always new
}
 
function db_secure($tpl_name, &$smarty_obj) {
    // assume all templates are secure
    return true;
}
 
function db_trusted($tpl_name, &$smarty_obj) {
    // not used for templates
    return true;
}
 

// register the resource name "db"
$smarty->register_resource("db", array(
"db_source",
                                  
"db_timestamp",
                                   "db_secure",
                                   "db_trusted"
) );
 
$smarty->display('db:blah');
 
?>

Hi.

You return false only on failure -- ie: you can't determine
the timestamp at
all. The implied condition is then that you can't locate
the requested resource
item. Otherwise, you should return true and populate
$tpl_timestamp with the
proper timestamp. If you want non-expiring templates and
don't intend to
look-up the proper timestamp, set the timestamp for
$tpl_timestamp to now
(perhaps with time()).
