Yaf整合Smarty模板引擎

引用：http://blog.csdn.net/xinxintai/article/details/9076363

1.下载好Smarty

目录结构如下：

（里面本来是没有Adapter.php文件的）

2.将Smarty文件夹放在library目录下面

3.在Smarty目录下面添加Adapter.php，代码如下：

<?php
Yaf_Loader::import( "Smarty/Smarty.class.php");
Yaf_Loader::import( "Smarty/sysplugins/smarty_internal_templatecompilerbase.php");
Yaf_Loader::import( "Smarty/sysplugins/smarty_internal_templatelexer.php");
Yaf_Loader::import( "Smarty/sysplugins/smarty_internal_templateparser.php");
Yaf_Loader::import( "Smarty/sysplugins/smarty_internal_compilebase.php");
Yaf_Loader::import( "Smarty/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);
        }       
        // var_dump($extraParams);
        foreach ($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);
    }

}
           

4.在application.ini中添加配置。如下：

smarty.left_delimiter   = "<{"  
smarty.right_delimiter  = "}>"  
smarty.template_dir     = APP_PATH "/application/views/"
smarty.compile_dir      = APP_PATH "/application/cache/compile"
smarty.cache_dir        = APP_PATH "/application/cache/"
           

5.使用Bootstrap.php文件

 在入口文件中：

$app->bootstrap()->run();
           

然后编辑Bootstrap.php文件。如下：

<?php

/**
 * 所有在Bootstrap类中, 以_init开头的方法, 都会被Yaf调用,
 * 这些方法, 都接受一个参数:Yaf_Dispatcher $dispatcher
 * 调用的次序, 和申明的次序相同
 */
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);
        }
}
