Zend Framework框架Smarty扩展实现方法,zendsmarty_PHP教程

zend framework框架smarty扩展实现方法,zendsmarty本文实例讲述了zend framework框架smarty扩展实现方法。分享给大家供大家参考,具体如下:
今天总结一下zf框架中扩展smarty模板的方法,在zf帮助文档中已经有比较详细的介绍,在这我稍微多说一些。
一.将smarty的核心文件包放在lib文件夹下,文件包中要包括(internals/,plugins/,config_file.class.php,smarty.class.php,smarty_compiler.class.php,debug.tpl).
二.在zend/view下添加文件:smarty.php ,文件的内容如下:
_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 string $path the directory to set as the path. * @return void */ public function setscriptpath($path) { if (is_readable($path)) { $this->_smarty->template_dir = $path; return; } throw new exception('invalid path provided'); } /** * set smarty缓存 * @author lengfeng */ public function setcompilepath($path){ if (is_readable($path)) { $this->_smarty->compile_dir = $path; return; } throw new exception('invalid path provided'); } /** * set smarty 编译后文档 * @author lengfeng */ public function setcachepath($path){ if (is_readable($path)) { $this->_smarty->cache_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 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); } /** * retrieve an assigned variable * * @param string $key the variable name. * @return mixed the variable value. */ public function __get($key) { return $this->_smarty->get_template_vars($key); } /** * allows testing with empty() and isset() to work * * @param 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) { return $this->_smarty->fetch($name); } /** * 设置是否生成缓存 * 如果没有参数,默认为true */ public function setcache($bool){ if (isset($bool)) { $this->_smarty->caching = $bool; return; } }}
三.在app文件夹下创建cache ,compile 文件夹
四.在config.ini 配置文件中加入
dir.compile = ../app/compiledir.cache = ../app/cache
三,四两步可以参见前面关于zendfreamwork框架搭建网站相关教程
五.在application.php 文件中添加
/*** 初始化smarty视图**/private function _initsmartyview(){ $view = new zend_view_smarty(); $view->setbasepath($this->_pathconfig->dir->viewbase); $view->setscriptpath($this->_pathconfig->dir->viewbase./scripts); $view->setcompilepath($this->_pathconfig->dir->compile); $view->setcachepath($this->_pathconfig->dir->cache); $smarty=$view->getengine(); $smarty->caching=false; $smarty->debugging = true; $smarty->compile_check = true; $smarty->left_delimiter = right_delimiter = }>; $registry = zend_registry::getinstance(); $registry->set('smartyview',$smarty); //smarty对象 $registry->set('sview',$view); }
并在 函数 init()中加入
$this->_initsmartyview();
六.在controller中调用
因为已经将对象注册,所以可以如下调用:
$view = zend_registry::getinstance()->get(smartyview);//注意这是smarty对象,使用smarty的那些语法,比如 $view->assign(user,root);$view = zend_registry::getinstance()->get(sview); //这是zf的view对象,按zf中的那些方法用,不用改变。//按这样,你如果要将以前写的代码改为用smaty,后台不用变了,只需要将视图文件改变就行了
