PHP框架中集成Smarty3模板引擎(二) ------ CakePHP 2.0

CakePHP 2.0 已经发布，我们尝试一下让他集成smarty 3.0模板引擎。

cakephp版本：2.0.6

smarty版本：3.1.7

步骤如下：

1. 在vendors(和app同级)下新建smarty文件夹，然后把下载下来的smarty包的libs下的文件拷贝进去。

2. 在app/View下新建SmartyView.php，代码如下

App::import('Vendor', 'Smarty', array('file' => 'smarty'.DS.'Smarty.class.php'));

class SmartyView extends View {
	
	function __construct (&$controller) {
	    parent::__construct($controller);
	    if (is_object($controller)) {
	        $count = count($this->__passedVars);
	        for ($j = 0; $j < $count; $j++) {
	            $var = $this->__passedVars[$j];
	            $this->{$var} = $controller->{$var};
	        }
	    }
	    $this->Smarty = new Smarty();
		//$this->ext= '.ctp';
	 	$this->Smarty->compile_dir = TMP.'smarty'.DS.'compile'.DS;
	 	$this->Smarty->cache_dir = TMP.'smarty'.DS.'cache'.DS;
		$this->Helpers = new HelperCollection($this);
	}

	protected function _render($___viewFn, $___dataForView = array()) {
		if (empty($___dataForView)) {
	        $___dataForView = $this->viewVars;
	    }
	    extract($___dataForView, EXTR_SKIP);
	    foreach($___dataForView as $data => $value) {
	        if(!is_object($data)) {
	            $this->Smarty->assign($data, $value);
	        }
	    }
	    //$this->Smarty->display($___viewFn);
	    $this->Smarty->assignByRef('this', $this);
	    return $this->Smarty->fetch($___viewFn);
	}
}

3. 在app/View/Layouts下新建default.tpl文件，代码如下：

Layout:




{$content_for_layout}

接下来我们可以使用smarty来编写测试代码：

在app/Controller下新建tests_controller.php，代码如下：

class TestsController extends AppController {

	var $viewClass = 'Smarty';
	//var $autoLayout = false;
	
	function index() {
		
		$name = 'Shen Bin';
		$date = date("Y-m-d H:i", time());
		
		$this->set(compact('date', 'name'));
	}
}

在app/View/tests下新建index.ctp，代码如下：

{$date}

Hello, {$name}!
