本文实例讲述了yii，CI，yaf框架+smarty模板使用方法。分享给大家供大家参考，具体如下：
最近折腾了框架的性能测试，其中需要测试各个模板跟smarty配合的性能，所以折腾了一桶，现总结一下。之前已经写过kohana框架+smarty模板，这里不再重复了。
一、yii框架+smarty模板
yii是覆盖了viewRenderer组件。
1.1，下载yii框架并解压，下载smarty框架并解压，将smarty/libs文件夹拷到yii框架application/protected/vendors下面，并重命名smarty。
1.2，yii配置文件main.php

'components'=>array( 'viewRenderer' => array( 'class'=>'batman.protected.extensions.SmartyViewRender', // 这里为Smarty支持的属性 'config' => array ( 'left_delimiter' => "{#", 'right_delimiter' => "#}", 'template_dir' => APP_DIR . "/views/", 'config_dir' => APP_DIR . "/views/conf/", 'debugging' => false, 'compile_dir' => 'D:/temp/runtime', )) |
其中batman是我已经在index.php定义好的别名。
|

|
Yii::setPathOfAlias('batman', dirname(__FILE__));Yii::import("batman.protected.vendors.*");define('APP_DIR', dirname(__FILE__).'/protected/'); |
1.3，在protected/extensions/下面新建SmartyViewRender.php

<?phpclass SmartyViewRender extends CApplicationComponent implements IViewRenderer { public $fileExtension = '.html'; private $_smarty = null; public $config = array(); public function init() { $smartyPath = Yii::getPathOfAlias('batman.protected.vendors.smarty'); Yii::$classMap['Smarty'] = $smartyPath . '/Smarty.class.php'; Yii::$classMap['Smarty_Internal_Data'] = $smartyPath . '/sysplugins/smarty_internal_data.php'; $this->_smarty = new Smarty(); // configure smarty if (is_array ( $this->config )) { foreach ( $this->config as $key => $value ) { if ($key {0} != '_') { // not setting semi-private properties $this->_smarty->$key = $value; } } } Yii::registerAutoloader('smartyAutoload'); } public function renderFile($context, $file, $data, $return) { foreach ($data as $key => $value) $this->_smarty->assign($key, $value); $return = $this->_smarty->fetch($file); if ($return) return $return; else echo $return; }} |
1.4，验证
新建一个HelloController.php

|
|

<?phpclass HelloController extends Controller { public function actionWorld() { $this->render('world', array('content'=>'hello world')); }} |
新建一个word.html
|

|
|

3
|
<body>{#$content#}</body> |
二、CI框架+smarty模板
网上很多方法，将smarty作为一个普通的library，在使用的时候，controller代码类似于下面：
|
1
|
|
2
3
4
5
6
7
8
9
|
public function index(){ $this->load->library('smarty/Ci_smarty', '', 'smarty'); $this->smarty->assign("title","恭喜你smarty安装成功！"); $this->smarty->assign("body","欢迎使用smarty模板引擎"); $arr = array(1=>'zhang',2=>'xing',3=>'wang'); $this->smarty->assign("myarray",$arr); $this->smarty->display('index_2.html');} |
这种方法跟CI自带的使用模板的方法
复制代码 代码如下:
$this->load->view();
不和谐，而且要一系列的
复制代码 代码如下:
$this->smarty->assign();
语句，麻烦不说，还破坏了原本CI的简洁美，所以果断唾弃之。
那怎么保持CI加载view时的简洁美呢，答案就是覆盖Loader类的view()方法。好吧，let's begin。
2.1，条件：
到官网上现在CI框架和smarty模板。
2.2，确保CI已经能跑起来
将CI框架解压到网站跟目录下，先写一个不带smarty模板的controller输出“hello world”。
2.3，引入smarty
将smarty解压，将libs文件夹考到application/third_paty下面，并将libs重命名smarty，重命名取什么都ok了，这里就叫smarty吧。
2.4，覆盖loader类的view()方法
因为view()方法在Loader类里，所以我要覆盖Loader的view()方法。
先看看$this->load->view()是怎么工作的？CI_Controller类的构造函数里有这么一行
复制代码 代码如下:
$this->load =& load_class('Loader', 'core');
load_class函数会先在application/core下面找config_item('subclass_prefix').Loader.php文件，找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在配置文件里写的你要继承CI核心类的子类的前缀。我使用的是默认值'MY_'。找到文件后，require该文件，然后new MY_Loader（如果application/core/MY_Loader.php存在），或者是new Loader，赋值给$this->load。
在application/core下面新建一个MY_Loader.php文件

<?phpdefine('DS', DIRECTORY_SEPARATOR);class MY_Loader extends CI_Loader { public $smarty; public function __construct() { parent::__construct(); require APPPATH.'third_party'.DS.'smarty'.DS.'smarty.class.php'; $this->smarty = new Smarty (); // smarty 配置 $this->smarty->template_dir= APPPATH.'views'.DS;//smarty模板文件指向ci的views文件夹 $this->smarty->compile_dir = 'd:/temp/tpl_c/'; $this->smarty->config_dir = APPPATH.'libraries/smarty/configs/'; $this->smarty->cache_dir = 'd:/temp/cache'; $this->smarty->left_delimiter = '{#'; $this->smarty->right_delimiter = '#}'; } public function view($view, $vars = array(), $return = FALSE) { // check if view file exists $view .= config_item('templates_ext'); $file = APPPATH.'views'.DS.$view; if (! file_exists ( $file ) || realpath ( $file ) === false) { exit( __FILE__.' '.__LINE__."<br/>View file {$file} does not exist, <br/>{$file} => {$view}"); } // changed by simeng in order to use smarty debug foreach ( $vars as $key => $value ) { $this->smarty->assign ( $key, $value ); } // render or return if ($return) { ob_start (); } $this->smarty->display ( $view ); if ($return) { $res = ob_get_contents (); ob_end_clean (); return $res; } }} |
我把template_ext配置成了".html"，这样就ok了。我们来验证一下吧。
2.5，验证
在controller下面建一个home.php

好了，可以试试你的成果了。
三、yaf框架+smarty模板
yaf是利用引导文件Bootstrap.php来加载smarty。
3.1，使用Bootstrap
在index.php中用
复制代码 代码如下:
$app->bootstrap()->run();
引入Bootstrap.php文件
3.2，在application/Bootstrap.php文件中导入smarty。
|

<?phpclass Bootstrap extends Yaf_Bootstrap_Abstract { public function _initSmarty(Yaf_Dispatcher $dispatcher) { $smarty = new Smarty_Adapter(null, Yaf_Application::app()->getConfig()->smarty); Yaf_Dispatcher::getInstance()->setView($smarty); }} |
3.3,添加Smarty_Adapter类
将smarty解压后放到application/library文件夹下，重命名为Smarty。在Smarty下新建Adapter.php，确保Smarty.class.php在Smarty/libs/下。Adapter.php内容：
