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 smartyif (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;elseecho $return; }}1.4,验证
新建一个HelloController.php
<?phpclass HelloController extends Controller { public function actionWorld() {$this->render("world", array("content"=>"hello world")); }}新建一个word.html
<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
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 debugforeach ( $vars as $key => $value ) { $this->smarty->assign ( $key, $value );}// render or returnif ($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>{#$v#}</li>{#/foreach#}</ul></body></html>好了,可以试试你的成果了。
三、yaf框架+smarty模板yaf是利用引导文件Bootstrap.php来加载smarty。
3.1,使用Bootstrap
在index.php中用
复制代码 代码如下:$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:
<?phpYaf_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 = TRUEapplication.view.ext="tpl"[smarty : common];configures for smartysmarty.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
