/**
|
|
* 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:
|
|
* <code>
|
|
* // 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');
|
|
*
|
|
* </code>
