Zend Framework实现Zend_View集成Smarty模板系统的方法

框架(架构)  /  管理员 发布于 7年前   157

本文实例讲述了Zend Framework实现Zend_View集成Smarty模板系统的方法。分享给大家供大家参考，具体如下：

Zend_View抽象出了Zend_View_Interface，可以让我们集成不同的视图解决方案，例如可以集成smarty。要在zend中使用其他视图系统作为视图，只要实现Zend_View_Interface接口即可。

Zend_View_Interface的接口定义:

 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);  /**   * 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();  /**   * Processes a view script and returns the output.   *   * @param string $name The script name to process.   * @return string The script output.   */  public function render($name);}

集成Smarty的基本实现如下：

_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 $path string   *      The directory to set as the path.   * @return void   */  public function setScriptPath($path) {    if (is_readable ( $path )) {      $this->_smarty->template_dir = $path;      return;    }    throw new Exception ( 'Invalid path provided' );  }  /**   * Retrieve the current template directory   *   * @return string   */  public function getScriptPaths() {    return array ($this->_smarty->template_dir );  }  /**   * Alias for setScriptPath   *   * @param $path string   * @param $prefix string   *      Unused   * @return void   */  public function setBasePath($path, $prefix = 'Zend_View') {    return $this->setScriptPath ( $path );  }  /**   * Alias for setScriptPath   *   * @param $path string   * @param $prefix string   *      Unused   * @return void   */  public function addBasePath($path, $prefix = 'Zend_View') {    return $this->setScriptPath ( $path );  }  /**   * Assign a variable to the template   *   * @param $key string   *      The variable name.   * @param $val mixed   *      The variable value.   * @return void   */  public function __set($key, $val) {    $this->_smarty->assign ( $key, $val );  }  /**   * Retrieve an assigned variable   *   * @param $key string   *      The variable name.   * @return mixed The variable value.   */  public function __get($key) {    return $this->_smarty->get_template_vars ( $key );  }  /**   * Allows testing with empty() and isset() to work   *   * @param $key string   * @return boolean   */  public function __isset($key) {    return (null !== $this->_smarty->get_template_vars ( $key ));  }  /**   * Allows unset() on object properties to work   *   * @param $key string   * @return void   */  public function __unset($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 $spec string|array   *      The assignment strategy to use (key or array of key   *      => value pairs)   * @param $value mixed   *      (Optional) If assigning a named variable, use this   *      as the value.   * @return void   */  public function assign($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 $name string   *      The template to process.   * @return string The output.   */  public function render($name) {    ob_start();    echo $this->_smarty->fetch ( $name );    unset($name);  }}

setScriptPath('/www/zf_demo1/application/views/scripts');    return $smarty;  }}

/zf_demo1/application/controllers/IndexController.php

_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');  }}

{$book}{$author}

如果需要配置smarty可以打开/zf_demo1/library/smartylib/Smarty.class.php文件进行相应配置例如

/*** Initialize new Smarty object**/public function __construct(){    // selfpointer needed by some other class methods    $this->smarty = $this;    if (is_callable('mb_internal_encoding')) {      mb_internal_encoding(Smarty::$_CHARSET);    }    $this->start_time = microtime(true);    // set default dirs    $this->setTemplateDir('/www/zf_demo1/temp/smarty' . DS . 'templates' . DS)      ->setCompileDir('/www/zf_demo1/temp/smarty' . DS . 'templates_c' . DS)      ->setPluginsDir(SMARTY_PLUGINS_DIR)      ->setCacheDir('/www/zf_demo1/temp/smarty' . DS . 'cache' . DS)      ->setConfigDir('/www/zf_demo1/temp/smarty' . DS . 'configs' . DS);    $this->debug_tpl = 'file:' . dirname(__FILE__) . '/debug.tpl';    if (isset($_SERVER['SCRIPT_NAME'])) {      $this->assignGlobal('SCRIPT_NAME', $_SERVER['SCRIPT_NAME']);    }}
