Zend Framework实现Zend_View集成Smarty模板系统的方法

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:

集成Smarty的基本实现如下：

_smarty = new Smarty ();
    if (null !== $tmplPath) {
      $this->setscriptPath ( $tmplPath );
    }
    foreach ( $extraParams as $key => $value ) {
      $this->_smarty->$key = $value;
    }

[production]
includePaths.library = APPLICATION_PATH "/../library"

bootstrap.class = "Bootstrap"
appnamespace = "Application"
autoloadernamespaces.lq = "Lq_"

/zf_demo1/application/Bootstrap.php

setscriptPath('/www/zf_demo1/application/views/scripts');
    return $smarty;
  }
}



/zf_demo1/application/controllers/IndexController.php

_helper->getHelper('viewRenderer')->setNoRender();
    $this->view = $this->getInvokeArg ( 'bootstrap' )->getResource ( 'smarty' );
    $this->view->book = 'Hello World! ';
    $this->view->author = 'by smarty';
    $this->view->render('index/index.tpl');
  }
}



/zf_demo1/application/views/scripts/index/index.tpl








{$book}
{$author}





如果需要配置smarty可以打开/zf_demo1/library/smartylib/Smarty.class.php文件进行相应配置例如


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']);
    }
}
