Problem with View Helpers

Question

I have written several specialized view helpers, but I have a slight problem with using them. If I add an auxiliary path to the controller action as follows:

public function fooAction() { $this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); } 

Then I can use the views from this path without problems. But when I add the path to the bootstrap file as follows:

 protected function _initView() { $this->view = new Zend_View(); $this->view->doctype('XHTML1_STRICT'); $this->view->headScript()->appendFile($this->view->baseUrl() . '/js/jquery-ui/jquery.js'); $this->view->headMeta()->appendHttpEquiv('Content-Type', 'text/html; charset=UTF-8'); $this->view->headMeta()->appendHttpEquiv('Content-Style-Type', 'text/css'); $this->view->headMeta()->appendHttpEquiv('Content-Language', 'sk'); $this->view->headLink()->appendStylesheet($this->view->baseUrl() . '/css/reset.css'); $this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); } 

Then view assistants do not work. Why is this? This is too troublesome to add a path to every controller action. Here is an example of what my view custom helpers look like:

 class My_View_Helper_FooBar { public function fooBar() { return 'hello world'; } } 

I use them like this:

 <?php echo $this->fooBar(); ?> 

Should I publish the entire boot file?

UPDATE:

Added a complete boot file just in case:

 class Bootstrap extends Zend_Application_Bootstrap_Bootstrap { protected function _initFrontController() { $this->frontController = Zend_Controller_Front::getInstance(); $this->frontController->addModuleDirectory(APPLICATION_PATH . '/modules'); Zend_Controller_Action_HelperBroker::addPath( 'My/Controller/Action/Helper', 'My_Controller_Action_Helper' ); $this->frontController->registerPlugin(new My_Controller_Plugin_Auth()); $this->frontController->setBaseUrl('/'); } protected function _initView() { $this->view = new Zend_View(); $this->view->doctype('XHTML1_STRICT'); $this->view->headScript()->appendFile($this->view->baseUrl() . '/js/jquery-ui/jquery.js'); $this->view->headMeta()->appendHttpEquiv('Content-Type', 'text/html; charset=UTF-8'); $this->view->headMeta()->appendHttpEquiv('Content-Style-Type', 'text/css'); $this->view->headMeta()->appendHttpEquiv('Content-Language', 'sk'); $this->view->headLink()->appendStylesheet($this->view->baseUrl() . '/css/reset.css'); $this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); } protected function _initDb() { $this->configuration = new Zend_Config_Ini(APPLICATION_PATH . '/configs/application.ini', APPLICATION_ENVIRONMENT); $this->dbAdapter = Zend_Db::factory($this->configuration->database); Zend_Db_Table_Abstract::setDefaultAdapter($this->dbAdapter); $stmt = new Zend_Db_Statement_Pdo($this->dbAdapter, "SET NAMES 'utf8'"); $stmt->execute(); } protected function _initAuth() { $this->auth = Zend_Auth::getInstance(); } protected function _initCache() { $frontend= array('lifetime' => 7200, 'automatic_serialization' => true); $backend= array('cache_dir' => 'cache'); $this->cache = Zend_Cache::factory('core', 'File', $frontend, $backend); } public function _initTranslate() { $this->translate = new Zend_Translate('Array', BASE_PATH . '/languages/Slovak.php', 'sk_SK'); $this->translate->setLocale('sk_SK'); } protected function _initRegistry() { $this->registry = Zend_Registry::getInstance(); $this->registry->configuration = $this->configuration; $this->registry->dbAdapter = $this->dbAdapter; $this->registry->auth = $this->auth; $this->registry->cache = $this->cache; $this->registry->Zend_Translate = $this->translate; } protected function _initUnset() { unset($this->frontController, $this->view, $this->configuration, $this->dbAdapter, $this->auth, $this->cache, $this->translate, $this->registry); } protected function _initGetRidOfMagicQuotes() { if (get_magic_quotes_gpc()) { function stripslashes_deep($value) { $value = is_array($value) ? array_map('stripslashes_deep', $value) : stripslashes($value); return $value; } $_POST = array_map('stripslashes_deep', $_POST); $_GET = array_map('stripslashes_deep', $_GET); $_COOKIE = array_map('stripslashes_deep', $_COOKIE); $_REQUEST = array_map('stripslashes_deep', $_REQUEST); } } public function run() { $frontController = Zend_Controller_Front::getInstance(); $frontController->dispatch(); } } 

Answer 1

solved. I just needed to add these lines at the end of the _initView () method:

 $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('ViewRenderer'); $viewRenderer->setView($this->view); 

Answer 2

There is something like this in my _initView ():

  protected function _initView() { $view = new Zend_View(); #some view initialization ... $view->addHelperPath(APPLICATION_PATH . '/views/helpers', 'My_View_Helper'); return $view; } 

Then in the view, I can do:

 <?php echo $this->fooBar(); ?> 

Without APPLICATION_PATH this does not work in my case.

Answer 3

Just a thought: are you sure that the view you create in your bootstrap ($ this-> view = new Zend_View ();) is the same as "$ this" in your view file?

I think you will need to change the initView code to the following:

 protected function _initView() { $view = new Zend_View(); $view->doctype('XHTML1_STRICT'); $view->headScript()->appendFile($this->view->baseUrl() . '/js/jquery-ui/jquery.js'); $view->headMeta()->appendHttpEquiv('Content-Type', 'text/html; charset=UTF-8'); $view->headMeta()->appendHttpEquiv('Content-Style-Type', 'text/css'); $view->headMeta()->appendHttpEquiv('Content-Language', 'sk'); $view->headLink()->appendStylesheet($this->view->baseUrl() . '/css/reset.css'); $view->addHelperPath('My/View/Helper', 'My_View_Helper'); return $view; } 

If you have some options related to View in the config.ini file, you can change your code a bit:

 protected function _initMyView() { $view = $this->bootstrap('view')->getResource('view'); ... 

instead:

 protected function _initView() { $view = new Zend_View(); .... 

Answer 4

You might consider adding another init function only to your view helpers:

 protected function _initViewHelpers() { $this->bootstrap('view'); $view = $this->getResource('view'); $view->addHelperPath('My/View/Helper', 'My_View_Helper'); } 

Thus, the built-in viewing function is not overridden.

Answer 5

If you add only $this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); in your bootstrap use this format:

 class Zend_View_Helper_FooBar extends Zend_View_Helper_Abstract { public function fooBar() { return 'hello world'; } }
