Hi, hoping someone can 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()).
