yii,CI,yaf框架+smarty模板使用方法

編輯:PHP綜合

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>
