Controller/Action.php

Default behavior is to throw an exception on undefined methods, however this function can be overridden to implement magic (dynamic) actions, or provide run-time dispatching.

The request and response objects should be registered with the controller, as should be any additional optional arguments; these will be available via getRequest(), getResponse(), and getInvokeArgs(), respectively.

When overriding the constructor, please consider this usage as a best practice and ensure that each is registered appropriately; the easiest way to do so is to simply call parent::__construct($request, $response, $invokeArgs).

After the request, response, and invokeArgs are set, the helper broker is initialized.

Finally, init() is called as the final action of instantiation, and may be safely overridden to perform initialization tasks; as a general rule, override init() instead of the constructor to customize an action controller's instantiation.

It is important to supply the unformatted names, i.e. "article" rather than "ArticleController". The dispatcher will do the appropriate formatting when the request is received.

If only an action name is provided, forwards to that action in this controller.

If an action and controller are specified, forwards to that action and controller in this module.

Specifying an action, controller, and module is the most specific way to forward.

A fourth argument, $params, will be used to set the request parameters. If either the controller or module are unnecessary for forwarding, simply pass null values for them before specifying the parameters.

If the parameter does not exist, NULL will be returned.

If the parameter does not exist and $default is set, then $default will be returned instead of NULL.

Used by render() to determine the path to the view script.

Called from __construct() as final step of object instantiation.

Initializes $view if not otherwise a Zend_View_Interface.

If $view is not otherwise set, instantiates a new Zend_View object, using the 'views' subdirectory at the same level as the controller directory for the current module as the base directory. It uses this to set the following: - script path = views/scripts/ - helper path = views/helpers/ - filter path = views/filters/

Called after action method execution. If using class with Zend_Controller_Front, it may modify the Request object and reset its dispatched flag in order to process an additional action.

Common usages for postDispatch() include rendering content in a sitewide template, link url correction, setting headers, etc.

Called before action method. If using class with Zend_Controller_Front, it may modify the Request object and reset its dispatched flag in order to skip processing the current action.

Proxies to Zend_Controller_Action_Helper_Redirector::gotoUrl().

Renders a view. By default, views are found in the view script path as /.phtml. You may change the script suffix by resetting $viewSuffix. You may omit the controller directory prefix by specifying boolean true for $noController.

By default, the rendered contents are appended to the response. You may specify the named body content segment to set by specifying a $name.

Similar to render(), this method renders a view script. Unlike render(), however, it does not autodetermine the view script via getViewScript(), but instead renders the script passed to it. Use this if you know the exact view script name and path you wish to use, or if using paths that do not conform to the spec defined with getViewScript().

By default, the rendered contents are appended to the response. You may specify the named body content segment to set by specifying a $name.

Not used in the Action Controller implementation, but left for usage in Page Controller implementations. Dispatches a method based on the request.

Returns a Zend_Controller_Response_Abstract object, instantiating one prior to execution if none exists in the controller.

preDispatch() is called prior to the action, postDispatch() is called following it.
