* @param string $key
* @return boolean
*/

public function render($name, $value = NULL) {
return $this->_smarty->fetch($name);
}
public function display($name, $value = NULL) {
echo $this->_smarty->fetch($name);
}
}

Example #2 Yaf_Dispatcher::setView()example
<?php
class Bootstrap extends Yaf_Bootstrap_Abstract {
/**
* there are some config for smarty in the config:
*
* smarty.left_delimiter = "{{"
* smarty.right_delimiter = "}}"
* smarty.template_dir = APPLICATION_PATH "/views/scripts/"
* smarty.compile_dir = APPLICATION_PATH "/views/templates_c/"
* smarty.cache_dir = APPLICATION_PATH "/views/templates_d/"
*
*/
public function _initConfig() {
$config = Yaf_Application::app()->getConfig();
Yaf_Registry::set("config", $config);
}
public function _initLocalName() {
/** we put class Smarty_Adapter under the local library directory */
Yaf_Loader::getInstance()->registerLocalNamespace('Smarty');
}
public function _initSmarty(Yaf_Dispatcher $dispatcher) {
$smarty = new Smarty_Adapter(null, Yaf_Registry::get("config")->get("smarty"));
$dispatcher->setView($smarty);
/* now the Smarty view engine become the default view engine of Yaf */
}
