<?php
Ciao Gianni,
sto cercando di utilizzare smarty al posto di Zend_View, per fare ciò ho creato una libreria in libs :
/Libs
/Zend
/Smarty
Smarty.class.php
Smarty_compiler.class.php
debug.tpl
Config_file.class.php
/internals
/plugins
/Mialibreria
/View
Smarty.php
/Controller
Base.phpMialibreria_View_Smarty è contenuta in Smarty.php
non è altro che Zend_View_Interface implementato sui metodi di smarty.
I file di smarty (Smarty/Smarty.class.php) vengono inclusi qui dentro.
il codice è questo :
<?php
include DIR_LIBS . 'Smarty/Smarty.class.php';
class Mialibreria_View_Smarty implements Zend_View_Interface
{
/**
* Smarty object
* @var Smarty
*/
protected $_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);
}
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 getScriptPaths()
{
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);
}
/**
* 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);
}
}Mialibreria_Controller_Base è la classe che utilizzo per la scrittura dei controller, questa estende Zend_Controller_Action
questa contiene metodi comuni a tutti i controller ed in più
<?php
class Mialibreria_Controller_Base extends Zend_Controller_Action
{
public function initView()
{
if (null === $this->view) {
if (Zend_Registry::isRegistered('view')) {
$this->view = Zend_Registry::get('view');
} else {
$this->view = new Mialibreria_View_smarty();
$this->view->setBasePath('var/templates/');
}
}
return $this->view;
}
public function init()
{
$this->_helper->removeHelper('viewRenderer');
}
}Se nel file di bootstrap
// ... ... ...
$frontController = Zend_Controller_Front::getInstance();
$frontController->setControllerDirectory(DIR_CONTROLLERS)
//->setParam('noViewRenderer', true)
->dispatch();
// ... ... ...rimuovo il commento a setparam ottengo una bella pagina bianca.
quando invece commento ottendo la mia pagina di errore gestita con :
<?php
require_once 'Zend/Controller/Action.php';
class ErrorController extends Mialibreria_Controller_Base
{
public function errorAction()
{
$errors = $this->_getParam('error_handler');
switch ($errors->type) {
case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
$this->getResponse()->setRawHeader('HTTP/1.1 404 Not Found');
$errorMessage = '404 Error Page Not found';
break;
default:
$logConfig = Zend_Registry::get('logConfig');
$errorType = 'Application Error';
$errorMessage = 'The system has reported an unknown error. A log file has been created for the event.';
include DIR_VAR . '/errors/startupError.html';
$exception = $errors->exception;
$writer = new Zend_Log_Writer_Stream($logConfig->saveDir . $logConfig->emergFile, 'wb');
$formatter = new Zend_Log_Formatter_Simple('%timestamp% %priorityName% (%priority%): %message%' . PHP_EOL);
$log = new Zend_Log($writer);
$log->log($exception->getMessage() . "\n" . print_r($exception->getTraceAsString(),true), Zend_Log::EMERG);
break;
}
}
}il log dice :
2007-10-21T16:01:50+02:00 EMERG (0): script 'catalog/view.phtml' not found in path (C:\Programmi\Apache Software Foundation\Apache2.2\htdocs\Mialibreria\app\default\views\scripts\)
