这篇文章主要介绍了yii,CI,yaf框架+smarty模板使用方法,结合实例形式介绍了yii,CI及yaf框架整合smaryt模板的使用技巧,具有一定参考借鉴价值,需要的朋友可以参考下。
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:
$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。
