yii，CI，yaf框架+smarty模板使用方法

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

<?php
class 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

<?php
class HelloController extends Controller {
 public function actionWorld() {
  $this->render('world', array('content'=>'hello world'));
 }
}

新建一个word.html

<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：

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

代码如下:

$this->load->view();

不和谐，而且要一系列的

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

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

<?php
define('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

class Home extends CI_Controller {
 public function index() {
  $data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
  $data['title'] = "恭喜你smarty安装成功！";
  $data['body'] = "欢迎使用smarty模板引";
  $arr = array(1=>'zhang',2=>'xing',3=>'wang');
  $data['myarray'] = $arr;
  $this->load->view('index_2', $data);
 }
}

在views下面建一个index_2.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 <script src='<!--{$base_url}-->js/jquery.min.js' type='text/javascript' ></script>
 <link href="<!--{$base_url}-->css/login.css" rel="stylesheet" type="text/css" />
 <title>smarty安装测试</title>
</head>
<body>
<h1>{#$title#}</h1>
<p>{#$body#}</p>
<ul>
  {#foreach from=$myarray item=v#}
  <li>{#$v#}</li>
  {#/foreach#}
</ul>
</body>
</html>

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

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。

<?php
class 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：

<?php
Yaf_Loader::import( "Smarty/libs/Smarty.class.php");
Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_templatecompilerbase.php");
Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_templatelexer.php");
Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_templateparser.php");
Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_compilebase.php");
Yaf_Loader::import( "Smarty/libs/sysplugins/smarty_internal_write_file.php");
class Smarty_Adapter implements Yaf_View_Interface
{
 /**
  * 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);
 }
}

3.4，smarty配置文件。

再来看看我们的conf/application.ini文件

[common]
application.directory = APP_PATH "/application"
application.dispatcher.catchException = TRUE
application.view.ext="tpl"
[smarty : common]
;configures for smarty
smarty.left_delimiter = "{#"
smarty.right_delimiter = "#}"
smarty.template_dir  = APP_PATH "/application/views/"
smarty.compile_dir  = '/data1/www/cache/'
smarty.cache_dir  = '/data1/www/cache/'
[product : smarty]

3.5，验证

新建一个controller，添加方法：

public function twoAction() {
  $this->getView()->assign('content', 'hello World');
}

新建一个模板two.tpl

<html>
<head>
<title>A Smarty Adapter Example</title>
</head>
<body>
{#$content#}
</body>
</html>

希望本文所述对大家PHP程序设计有所帮助。
