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(apizl_file));
Yii::import("batman.protected.vendors.*");
define('APP_DIR', dirname(apizl_file).'/protected/');

1.3,在protected/extensions/下面新建SmartyViewRender.php

_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

render('world', array('content'=>'hello world'));
 }
}

新建一个word.html


{#$content#}


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

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 ( $file ) === false) {
   exit( apizl_file.' '.apizl_line."
View file {$file} does not exist,
{$file} => {$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




 
 
 
 smarty安装测试


{#$title#}

{#$body#}

    {#foreach from=$myarray item=v#}
  • {#$v#}
  • {#/foreach#}

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。

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:

_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
