集成Zend框架和Smarty模板

類定義和構造函數

1.Smarty作為MVC架構中的試圖部分在Zend框架中要實現 Zend_VIEw_Abstract類

class Travello_View_Smarty extends Zend_VIEw_Abstract  {      private $_smarty = false;            public function __construct($data = array())      {          parent::__construct($data);

// 從對象倉庫中獲取配置對象          $config = Zend::registry('config');                    $this->_smarty = new Smarty();                    $this->_smarty->caching = $config->getSetting('smarty', 'caching');          $this->_smarty->cache_lifetime = $config->getSetting('smarty', 'cache_lifetime');          $this->_smarty->template_dir = $config->getSetting('smarty', 'template_dir');          $this->_smarty->compile_dir = $config->getSetting('smarty', 'compile_dir');          $this->_smarty->config_dir = $config->getSetting('smarty', 'config_dir');          $this->_smarty->cache_dir = $config->getSetting('smarty', 'cache_dir');      }

 2.實現 _run() 方法

_run()是唯一的要在Zend_VIEw_Abstract子類中實現的方法.他在render()方法中自動調用.我的實現僅使用display()方法生成和輸出模板

protected function _run($template)

{

$this->_smarty->display($template);

}

3.重寫assign()方法

public function assign($var) {

   if (is_string($var)) {
    $value = func_get_arg(1);
    $this->_smarty->assign($var, $value);    elseif (is_array($var)) {
    foreach ($var as $key => $value) {
     $this->_smarty->assign($key, $value);    } else {
    throw new Zend_VIEw_Exception('assign() expects a string or array, got ' . gettype($var));
   }

}

4.重寫 escape()方法

public function escape($var) {
   if (is_string($var)) {
    return parent :: escape($var);    elseif (is_array($var)) {
    foreach ($var as $key => $value) {
     $var[$key] = $this->escape($value);    } else {
    return $var; }
