Plugin classes are registered with
Zend_Controller_Front::registerPlugin(), and may be
registered at any time. The following snippet illustrates how a
plugin may be used in the controller chain:
<?php
class MyPlugin extends Zend_Controller_Plugin_Abstract
{
public function routeStartup(Zend_Controller_Request_Abstract $request)
{
$this->getResponse()
->appendBody("<p>routeStartup() called</p>\n");
}
public function routeShutdown(Zend_Controller_Request_Abstract $request)
{
$this->getResponse()
->appendBody("<p>routeShutdown() called</p>\n");
}
public function dispatchLoopStartup(
Zend_Controller_Request_Abstract $request)
{
$this->getResponse()
->appendBody("<p>dispatchLoopStartup() called</p>\n");
}
public function preDispatch(Zend_Controller_Request_Abstract $request)
{
$this->getResponse()
->appendBody("<p>preDispatch() called</p>\n");
}
public function postDispatch(Zend_Controller_Request_Abstract $request)
{
$this->getResponse()
->appendBody("<p>postDispatch() called</p>\n");
}
public function dispatchLoopShutdown()
{
$this->getResponse()
->appendBody("<p>dispatchLoopShutdown() called</p>\n");
}
}
$front = Zend_Controller_Front::getInstance();
$front->setControllerDirectory('/path/to/controllers')
->setRouter(new Zend_Controller_Router_Rewrite())
->registerPlugin(new MyPlugin());
$front->dispatch();
Assuming that no actions called emit any output, and only one action is called, the functionality of the above plugin would still create the following output:
<?php
<p>routeStartup() called</p>
<p>routeShutdown() called</p>
<p>dispatchLoopStartup() called</p>
<p>preDispatch() called</p>
<p>postDispatch() called</p>
<p>dispatchLoopShutdown() called</p>
Note
Plugins may be registered at any time during the front controller execution. However, if an event has passed for which the plugin has a registered event method, that method will not be triggered.
