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;
}
}
public function getEngine()
{
return $this->_smarty;
}
public function setscriptPath($path)
{
if (is_readable($path)) {
$this->_smarty->template_dir = $path;
return;
}
throw new Exception('Invalid path provided');
}
public function setCompilePath($path){
if (is_readable($path)) {
$this->_smarty->compile_dir = $path;
return;
}
throw new Exception('Invalid path provided');
}
public function setCachePath($path){
if (is_readable($path)) {
$this->_smarty->cache_dir = $path;
return;
}
throw new Exception('Invalid path provided');
}
public function getscriptPaths()
{
return array($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, $value = null)
{
if (is_array($spec)) {
$this->_smarty->assign($spec);
return;
}
$this->_smarty->assign($spec, $value);
}
public function clearVars()
{
$this->_smarty->clear_all_assign();
}
public function render($name)
{
return $this->_smarty->fetch($name);
}
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/compile dir.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
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 = "<{"; //定义标示符
$smarty->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
