View script integration

Zend_Controller_Action_Helper_ViewRenderer provides transparent view integration for action controllers. It allows you to create a view object once, and populate it throughout all actions. Several global options may be set: - noController: if set true, render() will not look for view scripts in subdirectories named after the controller - viewSuffix: what view script filename suffix to use The helper autoinitializes the action controller view preDispatch(). It determines the path to the class file, and then determines the view base directory from there. It also uses the module name as a class prefix for helpers and views such that if your module name is 'Search', it will set the helper class prefix to 'Search_View_Helper' and the filter class prefix to ; 'Search_View_Filter'. Usage:


// In your bootstrap:
Zend_Controller_Action_HelperBroker::addHelper(new Zend_Controller_Action_Helper_ViewRenderer());

// In your action controller methods:
$viewHelper = $this->_helper->getHelper('view');

// Don't use controller subdirectories
$viewHelper->setNoController(true);

// Specify a different script to render:
$this->_helper->viewRenderer('form');
