Zend Framework 整合 Smarty 模板引擎實作指南

實作原理

Zend_View 抽象出 Zend_View_Interface，實作該介面即可整合第三方模板引擎（如 Smarty）。核心方法包括：getEngine()、setScriptPath()、assign()、render() 等。

└── public/index.php

關鍵程式碼

1. Smarty 介面實作 (Lq/View/Smarty.php)

require_once 'smartylib/Smarty.class.php';
class Lq_View_Smarty implements Zend_View_Interface {
    protected $_smarty;
    public function __construct($tmplPath = null, $extraParams = []) {
        $this->_smarty = new Smarty();
        if ($tmplPath) $this->setScriptPath($tmplPath);
        foreach ($extraParams as $k => $v) $this->_smarty->$k = $v;
    }
    public function getEngine() { return $this->_smarty; }
    public function setScriptPath($path) {
        if (is_readable($path)) { $this->_smarty->template_dir = $path; return; }
        throw new Exception('Invalid path');
    }
    public function getScriptPaths() { return [$this->_smarty->template_dir]; }
    public function setBasePath($path, $prefix = 'Zend_View') { return $this->setScriptPath($path); }
    public function addBasePath($path, $prefix = 'Zend_View') { return $this->setScriptPath($path); }
    public function __set($key, $val) { $this->_smarty->assign($key, $val); }
    public function __get($key) { return $this->_smarty->get_template_vars($key); }
    public function __isset($key) { return null !== $this->_smarty->get_template_vars($key); }
    public function __unset($key) { $this->_smarty->clear_assign($key); }
    public function assign($spec, $val = null) {
        is_array($spec) ? $this->_smarty->assign($spec) : $this->_smarty->assign($spec, $val);
    }
    public function clearVars() { $this->_smarty->clear_all_assign(); }
    public function render($name) {
        ob_start();
        echo $this->_smarty->fetch($name);
        return ob_get_clean();
    }
}

2. 應用配置 (application.ini)

[production]
autoloadernamespaces.lq = "Lq_"
pluginpaths.Lq_View_Smarty = "Lq/View/Smarty"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.params.displayExceptions = 1

3. Bootstrap 初始化

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap {
    protected function _initSmarty() {
        $smarty = new Lq_View_Smarty();
        $smarty->setScriptPath(APPLICATION_PATH . '/views/scripts');
        return $smarty;
    }
}

4. 控制器使用

class IndexController extends Zend_Controller_Action {
    public function indexAction() {
        $this->_helper->getHelper('viewRenderer')->setNoRender();
        $this->view = $this->getInvokeArg('bootstrap')->getResource('smarty');
        $this->view->book = 'Hello World!';
        $this->view->author = 'by smarty';
        $this->view->render('index/index.tpl');
    }
}

5. Smarty 模板 (index.tpl)

{$book} {$author}

Smarty 進階配置

可修改 smartylib/Smarty.class.php 建構子設定編譯、快取、配置目錄等：

$this->setTemplateDir('/www/zf_demo1/temp/smarty/templates/')
     ->setCompileDir('/www/zf_demo1/temp/smarty/templates_c/')
     ->setCacheDir('/www/zf_demo1/temp/smarty/cache/')
     ->setConfigDir('/www/zf_demo1/temp/smarty/configs/');
