Yaf 结合用户自定义的视图（模板）引擎Smarty（Yaf + Smarty）
分类：php开发
yafsmarty
（1）入口文件：/public/index.php:
<?phpdefine("DS", '/');define('APPLICATION_PATH', dirname(__FILE__).DS.'..'.DS);//指向public上一级的目录 ../$application = new Yaf_Application( APPLICATION_PATH . "/conf/application.ini");$application->bootstrap()->run();?>
（2）在引导程序
class Bootstrap extends Yaf_Bootstrap_Abstract{public function _initConfig() {//把配置保存起来$arrConfig = Yaf_Application::app()->getConfig();Yaf_Registry::set('config', $arrConfig);}//其他定义忽略……public function _initSmarty(Yaf_Dispatcher $dispatcher) {//init smarty view engine$smarty = new Smarty_Adapter(null, Yaf_Registry::get("config")->get("smarty"));$dispatcher->setView($smarty);}}
（3）添加类，使Smarty_Adapter
首先下载
vim Adapter.php <?php/*确保Smarty.class.php在Smarty/libs/下*/Yaf_Loader::import( "Smarty/libs/Smarty.class.php"); /*基类目录为library*/class Smarty_Adapter implements Yaf_View_Interface /*Smarty_Adapter类为yaf与smarty之间的适配器*/{/*** Smarty object* @var Smarty*/public $_smarty;/*** Constructor** @param string $tmplPath* @param array $extraParams* @return void*/public function __construct($tmplPath = null, $extraParams = array()) {$this->_smarty = new Smarty;if (null !== $tmplPath) {$this->setScriptPath($tmplPath);}foreach ($extraParams as $key => $value) {$this->_smarty->$key = $value;}}/*** Return the template engine object** @return Smarty*/public function getEngine() {return $this->_smarty;}/*** Set the path to the templates** @param string $path The directory to set as the path.* @return void*/public function setScriptPath($path){if (is_readable($path)) {$this->_smarty->template_dir = $path;return;}throw new Exception('Invalid path provided');} /*** Retrieve the current template directory** @return string*/public function getScriptPath(){return $this->_smarty->template_dir;}/*** Alias for setScriptPath** @param string $path* @param string $prefix Unused* @return void*/public function setBasePath($path, $prefix = 'Zend_View'){return $this->setScriptPath($path);}/*** Alias for setScriptPath** @param string $path* @param string $prefix Unused* @return void*/public function addBasePath($path, $prefix = 'Zend_View'){return $this->setScriptPath($path);}/*** Assign a variable to the template** @param string $key The variable name.* @param mixed $val The variable value.* @return void*/public function __set($key, $val){$this->_smarty->assign($key, $val);}/*** Allows testing with empty() and isset() to work** @param string $key* @return boolean*/public function __isset($key){return (null !== $this->_smarty->get_template_vars($key));}/*** Allows unset() on object properties to work** @param string $key* @return void*/public function __unset($key){$this->_smarty->clear_assign($key);}/*** Assign variables to the template** Allows setting a specific key to the specified value, OR passing* an array of key => value pairs to set en masse.** @see __set()* @param string|array $spec The assignment strategy to use (key or* array of key => value pairs)* @param mixed $value (Optional) If assigning a named variable,* use this as the value.* @return void*/public function assign($spec, $value = null) {if (is_array($spec)) {$this->_smarty->assign($spec);return;}$this->_smarty->assign($spec, $value);}/*** Clear all assigned variables** Clears all variables assigned to Zend_View either via* {@link assign()} or property overloading* ({@link __get()}/{@link __set()}).** @return void*/public function clearVars() {$this->_smarty->clear_all_assign();}/*** Processes a template and returns the output.** @param string $name The template to process.* @return string The output.*/public function render($name, $value = NULL) {return $this->_smarty->fetch($name);}public function display($name, $value = NULL) {echo $this->_smarty->fetch($name);}}?>
（4）修改

（5）基于Yaf+Smarty
快忘了那些不高兴的事吧!你看就连今天的阳光都如此明媚灿烂，
