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

$this->load->view();
不和谐,而且要一系列的
$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

$this->load =& load_class('Loader', 'core');
load_class函数会先在application/core下面找config_item('subclass_prefix').Loader.php文件,找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在配置文件里写的你要继承CI核心类的子类的前缀。我使用的是默认值'MY_'。找到文件后,require该文件,然后new MY_Loader(如果application/core/MY_Loader.php存在),或者是new Loader,赋值给$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

$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。
