本文實例講述了yii,CI,yaf框架+smarty模板使用方法。分享給大家供大家參考,具體如下:
最近折騰了框架的性能測試,其中需要測試各個模板跟smarty配合的性能,所以折騰了一桶,現總結一下。之前已經寫過kohana框架+smarty模板,這裡不再重復了。
一、yii框架+smarty模板
yii是覆蓋了viewRenderer組件。
1.1,下載yii框架並解壓,下載smarty框架並解壓,將smarty/libs文件夾拷到yii框架application/protected/vendors下面,並重命名smarty。
1.2,yii配置文件main.php
'components'=>array( 'viewRenderer' => array( 'class'=>'batman.protected.extensions.SmartyViewRender', // 這裡為Smarty支持的屬性 '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是我已經在index.php定義好的別名。
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,驗證
新建一個HelloController.php
<?php class HelloController extends Controller { public function actionWorld() { $this->render('world', array('content'=>'hello world')); } }
新建一個word.html
<body> {#$content#} </body>
二、CI框架+smarty模板
網上很多方法,將smarty作為一個普通的library,在使用的時候,controller代碼類似於下面:
public function index() { $this->load->library('smarty/Ci_smarty', '', 'smarty'); $this->smarty->assign("title","恭喜你smarty安裝成功!"); $this->smarty->assign("body","歡迎使用smarty模板引擎"); $arr = array(1=>'zhang',2=>'xing',3=>'wang'); $this->smarty->assign("myarray",$arr); $this->smarty->display('index_2.html'); }
這種方法跟CI自帶的使用模板的方法
復制代碼 代碼如下:$this->load->view();
不和諧,而且要一系列的
復制代碼 代碼如下:$this->smarty->assign();
語句,麻煩不說,還破壞了原本CI的簡潔美,所以果斷唾棄之。
那怎麼保持CI加載view時的簡潔美呢,答案就是覆蓋Loader類的view()方法。好吧,let's begin。
2.1,條件:
到官網上現在CI框架和smarty模板。
2.2,確保CI已經能跑起來
將CI框架解壓到網站跟目錄下,先寫一個不帶smarty模板的controller輸出“hello world”。
2.3,引入smarty
將smarty解壓,將libs文件夾考到application/third_paty下面,並將libs重命名smarty,重命名取什麼都ok了,這裡就叫smarty吧。
2.4,覆蓋loader類的view()方法
因為view()方法在Loader類裡,所以我要覆蓋Loader的view()方法。
先看看$this->load->view()是怎麼工作的?CI_Controller類的構造函數裡有這麼一行
復制代碼 代碼如下:$this->load =& load_class('Loader', 'core');
load_class函數會先在application/core下面找config_item('subclass_prefix').Loader.php文件,找不到再到system/core下面找Loader.php。config_item('subclass_prefix')就是在配置文件裡寫的你要繼承CI核心類的子類的前綴。我使用的是默認值'MY_'。找到文件後,require該文件,然後new MY_Loader(如果application/core/MY_Loader.php存在),或者是new Loader,賦值給$this->load。
在application/core下面新建一個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文件夾 $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",這樣就ok了。我們來驗證一下吧。
2.5,驗證
在controller下面建一個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安裝成功!"; $data['body'] = "歡迎使用smarty模板引"; $arr = array(1=>'zhang',2=>'xing',3=>'wang'); $data['myarray'] = $arr; $this->load->view('index_2', $data); } }
在views下面建一個index_2.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script src='<!--{$base_url}-->js/jquery.min.js' type='text/javascript' ></script> <link href="<!--{$base_url}-->css/login.css" rel="stylesheet" type="text/css" /> <title>smarty安裝測試</title> </head> <body> <h1>{#$title#}</h1> <p>{#$body#}</p> <ul> {#foreach from=$myarray item=v#} <li>{#$v#}</li> {#/foreach#} </ul> </body> </html>
好了,可以試試你的成果了。
三、yaf框架+smarty模板
yaf是利用引導文件Bootstrap.php來加載smarty。
3.1,使用Bootstrap
在index.php中用
復制代碼 代碼如下:$app->bootstrap()->run();
引入Bootstrap.php文件
3.2,在application/Bootstrap.php文件中導入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類
將smarty解壓後放到application/library文件夾下,重命名為Smarty。在Smarty下新建Adapter.php,確保Smarty.class.php在Smarty/libs/下。Adapter.php內容:
<?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。
再來看看我們的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,驗證
新建一個controller,添加方法:
public function twoAction() { $this->getView()->assign('content', 'hello World'); }
新建一個模板two.tpl
<html> <head> <title>A Smarty Adapter Example</title> </head> <body> {#$content#} </body> </html>
希望本文所述對大家PHP程序設計有所幫助。
