Routing zend request through a default controller when controller not found.

Question

Below is a function defined in my Bootstrap class. I must be missing something fundamental in the way Zend does routing and dispatching. What I am trying to accomplish is simple: For any request /foo/bar/* that is not dispatchable for any reason try /index/foo/bar/. The problem I'm having is when the FooController exists I get Action "foo" does not exist. Basically, the isDispatchable is always false.

public function run() {
        $front = Zend_Controller_Front::getInstance();
        $request = $front->getRequest();
        $dispatcher = $front->getDispatcher();
        //$controller = $dispatcher->getControllerClass($request);
        if (!$dispatcher->isDispatchable($request)) {
            $route = new Zend_Controller_Router_Route(
                ':action/*',
                array('controller' => 'index')
            );
            $router = $front->getRouter();
            $router->addRoute('FallBack', $route);
        }
        $front->dispatch();
    }

Hi , if i understand your idea right would you try to use __call magic method ?? then use $this->_redirect(); to your default action for example

more info are here http://php.net/manual/en/language.oop5.overloading.php

UPDATE

if you opened Zend/Controller/Action.php on line 480

public function __call($methodName, $args)
    {
        require_once 'Zend/Controller/Action/Exception.php';
        if ('Action' == substr($methodName, -6)) {
            $action = substr($methodName, 0, strlen($methodName) - 6);
            throw new Zend_Controller_Action_Exception(sprintf('Action "%s" does not exist and was not trapped in __call()', $action), 404);
        }

        throw new Zend_Controller_Action_Exception(sprintf('Method "%s" does not exist and was not trapped in __call()', $methodName), 500);
    }

what i meant to do is to extend this class and override __call function exactly to be

classs My_Controller_Action extends Zend_Controller_Action{
   public function __call($methodName, $args)
        {
            ///// do your magic here ......redirection or logging the request or what ever 
        }
}

and make sure your controller extend your newly created class

class FooController extends My_Controller_Action
{
   public function indexAction()
    {
        // action body
    }
}

so if some how you called inexistent action __call will run this idea was about inexistent action only it won't work if the controller doesn't exist

So this seems to work, but is not the best answer as it simply drops all the params. I might try shortly doing a forward to /index/[original uri] within the plugin:

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap {
  protected function _initRoute() {
    $front = Zend_Controller_Front::getInstance();
    $routes = array(
      'FallBack' => new Zend_Controller_Router_Route(
        ':controller/:action/*',
        array('controller' => 'index', 'action' => 'index')
      )
    );
    $router = $front->getRouter();
    $router->removeDefaultRoutes();
    $router->addRoutes($routes);
    $front->setRouter($router);
    return $router;
  }

  protected function _initPlugin() {
    $front = Zend_Controller_Front::getInstance();
    $front->registerPlugin(new My_Controller_Plugin_FallBack());
  }
    }

class My_Controller_Plugin_FallBack extends Zend_Controller_Plugin_Abstract {
  public function preDispatch(Zend_Controller_Request_Abstract $request) {
    $front = Zend_Controller_Front::getInstance();
    $dispatcher = $front->getDispatcher();
    $router = $front->getRouter();
    if (($router->getCurrentRouteName() == 'FallBack') &&
        !$dispatcher->isDispatchable($request)) {
      $request->setActionName($request->getControllerName());
      $request->setControllerName('index');
    }
  }
}
