标题: Zend Framework实现Zend_View集成Smarty模板系统的方法 [打印本页]

作者: yj1281 时间: 2018-2-14 05:38

         本文实例讲述了Zend Framework实现Zend_View集成Smarty模板系统的方法。分享给大家供大家参考，具体如下：
Zend_View抽象出了Zend_View_Interface，可以让我们集成不同的视图解决方案，例如可以集成smarty。要在zend中使用其他视图系统作为视图，只要实现Zend_View_Interface接口即可。
Zend_View_Interface的接口定义:
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);
  /**
* 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();
  /**
* Processes a view script and returns the output.
*
* @param string $name The script name to process.
* @return string The script output.
*/
  public function render($name);
}
集成Smarty的基本实现如下：

*/
public function __construct()
{
// selfpointer needed by some other class methods
$this->smarty = $this;
if (is_callable('mb_internal_encoding')) {
   mb_internal_encoding(Smarty:

_CHARSET);
}
$this->start_time = microtime(true);
// set default dirs
$this->setTemplateDir('/www/zf_demo1/temp/smarty' . DS . 'templates' . DS)
   ->setCompileDir('/www/zf_demo1/temp/smarty' . DS . 'templates_c' . DS)
   ->setPluginsDir(SMARTY_PLUGINS_DIR)
   ->setCacheDir('/www/zf_demo1/temp/smarty' . DS . 'cache' . DS)
   ->setConfigDir('/www/zf_demo1/temp/smarty' . DS . 'configs' . DS);
$this->debug_tpl = 'file:' . dirname(__FILE__) . '/debug.tpl';
if (isset($_SERVER['SCRIPT_NAME'])) {
   $this->assignGlobal('SCRIPT_NAME', $_SERVER['SCRIPT_NAME']);
}
