How to display error 404 page in multi modules using main error controller?

I can't make not found error page.

router.php

$router = new Phalcon\Mvc\Router();

$router->removeExtraSlashes(true);

// required for modules.
$router->setDefaultModule('core');

$router->add(
    '/{lang:[a-z]{2}}/index/:action/:params',
    array(
        'module' => 'core',
        'controller' => 'index',
        'action' => 2,
        'params' => 3,
    )
);
$router->add(
    '/{lang:[a-z]{2}}', 
    array(
        'module' => 'core',
        'controller' => 'index',
        'action' => 'index',
    )
);

services.php

// set dispatcher
$di->set('dispatcher', function() use ($di) {
    $evManager = $di->getShared('eventsManager');

    $evManager->attach('dispatch:beforeException', function($event, $dispatcher, $exception) {
        switch ($exception->getCode()) {
            case PhDispatcher::EXCEPTION_HANDLER_NOT_FOUND:
            case PhDispatcher::EXCEPTION_ACTION_NOT_FOUND:
                $dispatcher->forward(
                    array(
                        'module' => 'core',
                        'controller' => 'error',
                        'action' => 'e404',
                    )
                );
                return false;
        }
    });

    $dispatcher = new PhDispatcher();
    $dispatcher->setEventsManager($evManager);
    $dispatcher->setDefaultNamespace('Core\\Controllers');
    return $dispatcher;
});

index.php

$application = new \Phalcon\Mvc\Application($di);
    $application->registerModules(
        array(
            'core' => array(
                'className' => 'Core\\Module',
                'path' => APPFULLPATH . '/Module.php',
            ),
            'contact' => array(
                'className' => 'Modules\\Contact\\Module',
                'path' => ROOTFULLPATH . '/modules/contact/Module.php',
            )
        )
    );

Request the page to /index/action-not-exists action-not-exists is not exists in the index controller. but it is not forward to error page.

"Action 'action-not-exists' was not found on handler 'index'"

This is what i got instead of my 404 page.

How to make 404 error page and use in all modules?

--

update: 01

My source code are here https://github.com/OkveeNet/phalcon-begins

Now i can manage to display error 404 page But i have to add this code in every modules. https://github.com/OkveeNet/phalcon-begins/blob/master/core/Module.php

How to make it work in All modules at once? or How to make it use only main settings?

--

Dear Phalcon, please make it easier to manage error pages just like other frameworks.

use this simple solution instead (just add notFound route to your router):

$router = new Phalcon\Mvc\Router();

// add routes .....

$router->notFound(array(
  'module' => 'default',
  "controller" => "error",
  "action" => "notFound"
));

// blah blah blah ....

$di->set('router', $router);

No, it is not working.

What is your phalcon version?!!!

I've used this method in more that 5 production project by Phalcon 2.0!!!

for example check by this App https://beta.abplus.ir and add any path you want like https://beta.abplus.ir/blahblahblah

I'm using Phalcon 1.3.4.

However i'm using dynamic router and multi module and language uri.

Maybe exception code is not the expected, it could also be

Dispatcher::EXCEPTION_NO_DI
Dispatcher::EXCEPTION_CYCLIC_ROUTING
Dispatcher::EXCEPTION_INVALID_HANDLER
Dispatcher::EXCEPTION_INVALID_PARAMS

                return false;
        }
    });

    $dispatcher = new PhDispatcher();
    $dispatcher->setEventsManager($evManager);
    $dispatcher->setDefaultNamespace('Core\\Controllers');
    return $dispatcher;
});

It is not even exit.

This is my 404 handling code that works perfectly before using the method that i mentioned in my previous post. you can try this one too.

        $dispatcher    = new \Phalcon\Mvc\Dispatcher();
        $eventsManager = new \Phalcon\Events\Manager();

        $eventsManager->attach("dispatch", function ($event, $dispatcher, $exception) use ($di) {
                if ($event->getType() == 'beforeNotFoundAction') {
                    $di->get('response')->redirect('site/error/notFound');

                    return false;
                }

            if ($event->getType() == 'beforeException') {
                    switch ($exception->getCode()) {
                        case \Phalcon\Dispatcher::EXCEPTION_HANDLER_NOT_FOUND:
                        case \Phalcon\Dispatcher::EXCEPTION_ACTION_NOT_FOUND:
                            $di->get('response')->redirect('site/error/notFound');
                            return false;
                        default:
                            $di->get('response')->redirect('site/error/internalError');
                            return false;
                    }
                }

            });

        $dispatcher->setEventsManager($eventsManager);
        $di->setShared('dispatcher', $dispatcher);

                  }
              }

          });

      $dispatcher->setEventsManager($eventsManager);
      $di->setShared('dispatcher', $dispatcher);

From my latest source code here https://github.com/OkveeNet/phalcon-begins

I can make it work about...

not found module\controller -> 404 error page.

not found module\controller\action -> 404 error page.

But not found module or [module is not registered] to 404 error page still does not working.

$di->set('dispatcher' is not working for "module is not registered"!



6.2k

For module ... is not registered. I tried to use catch {...} to match error message because there is no support from Phalcon about module not registered error.

try {
    echo $application->handle()->getContent();
} catch (\Exception $e) {
        if (preg_match('/Module (.*) is not registered/ius', $e->getMessage()) == 1) {
        $dispatch = $di->getShared('dispatch');
        $dispatcher->forward(
            array(
                'namespace' => 'Core\\Controllers',
                'module' => 'core',
                'controller' => 'error',
                'action' => 'e404',
            )
        );
        return false;
    }
}

But i'm still cannot send it to use Error controller. Does anyone help?
