how to create 404 error page for manual bootstrap for example in this app ? http://album-o-rama.phalconphp.com/
i use this 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(

'action' => 'show404',
)
);
return false;
}
}

Answer 1

Try this in your index.php:
$di->set('dispatcher', function() {
$eventsManager = new \Phalcon\Events\Manager();
$eventsManager->attach("dispatch:beforeException", function($event, $dispatcher, $exception) {
//Handle 404 exceptions
if ($exception instanceof \Phalcon\Mvc\Dispatcher\Exception) {
$dispatcher->forward(array(
'controller' => 'index',
'action' => 'show404'
));
return false;
}
//Handle other exceptions
$dispatcher->forward(array(
'controller' => 'index',
'action' => 'show503'
));
return false;
});
$dispatcher = new \Phalcon\Mvc\Dispatcher();
//Bind the EventsManager to the dispatcher
$dispatcher->setEventsManager($eventsManager);
return $dispatcher;
}, true);

The recommended functionality here is:
http://docs.phalconphp.com/en/latest/reference/routing.html#not-found-paths
and maybe
routing.html#dealing-with-extra-trailing-slashes
For manual bootstrap, instead of use dispatcher, you could set a router
/**
* Registering a router
*/
$di->set('router', require __DIR__.'/../common/config/routes.php');
Then add this route rule at 'common/config/routes.php'.
$router->notFound(array(
'module' => 'frontend',
'namespace' => 'AlbumOrama\Frontend\Controllers\\',
'controller' => 'index',
'action' => 'route404'
));
Finally define a controller and a view to capture this action.
And voilà: 404 error page!
Just for comment, I pull request this solution for the app you mentioned:

For new version of Phalcon you can handle error using routes by adding this code to service.php
$di->set('router',function() use($Config){
$router = new \Phalcon\Mvc\Router();
$router->notFound(array(
"controller" => "error",
"action" => "error404"
));
return $router;
});

public function show404Action()
{
$this->response->setStatusCode(404, 'Not Found');
$this->view->pick('error/show404');
}
