Can I have an action that doesn't load a template? - php

Question

I got an answer to this question here, but now I have another concern\problem.
I have a subnav bar in my module created from a view partial via a helper.
Here is the config in module.config.php:
'navigation' => array(
'default' => array(
array(
'label' => 'Search',
'route' => 'mymodule\search',
),
array(
'label' => 'Log Off',
'route' => 'logout',
),
),
),
I have a LoginController with 2 actions: login and logout. After logging in I want the user to click the logout button, be redirected to the login page and have their session cleared.
Now if I have a login and logout action I need a template for each. This seems unnecessary for the logout action- I don't want another template to load for this action.
Here's my routing config:
'login' => array(
'type' => 'Zend\Mvc\Router\Http\Literal',
'options' => array(
'route' => '/login',
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Application\Controller\Login',
'action' => 'login',
),
),
),
'logout' => array(
'type' => 'Zend\Mvc\Router\Http\Literal',
'options' => array(
'route' => '/login',
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Application\Controller\Login',
'action' => 'logout',
),
),
),
Is there a correct way to have an action get called without loading a corresponding template?

Answer 1

You can return a response object instead:
public function logoutAction()
{
// do stuff
return $this->redirect()->toRoute('login');
}
then you don't need a template.

Answer 2

On zf2
public function Action(){
$vm = new ViewModel();
$vm->setTerminal(true);
return $vm;
}
EDIT:::
In case that you want to return a custom response you can do:
public function Action(){
return $this->getResponse()->setContent("Hello world!");
}
