prevent merging two module config in Zend Framework 2 - php

Question

I have two module in my ZF2 application, both module have different configuration for themself, and both module have different Module.php with different configruation inside it.
I have a login process for Admin, which is defined in Module.php like below:
in onBootstrap funtion:
public function onBootstrap($e) {
$e->getApplication()->getEventManager()->getSharedManager()->attach('Zend\Mvc\Controller\AbstractActionController', 'dispatch', function($e) {
$controller = $e->getTarget();
$controllerClass = get_class($controller);
$moduleNamespace = substr($controllerClass, 0, strpos($controllerClass, '\\'));
if ('Admin' === $moduleNamespace) {
$controller->layout('layout/admin');
}
}, 100);
$application = $e->getApplication();
$eventManager = $application->getEventManager();
..........
..........
$eventManager->attach(MvcEvent::EVENT_DISPATCH, array($this, 'boforeDispatch'), 100);
}
boforeDispatch function which is called inside the onBootstrap for login process check
function boforeDispatch(MvcEvent $event) {
......
//did something
......
}
Whenever I am going to run Front module, Admin module's function beforeDispatch is running. I also tried to define another function inside Front module with no content inside so that it could not merge it.

I have written different 404 template for both module, but Front's template is running. Here is the code.:
'view_manager' => array(
'display_not_found_reason' => true,
'display_exceptions' => true,
'doctype' => 'HTML5',
'not_found_template' => 'error/404',
'exception_template' => 'error/index',
'template_map' => array(
'layout/front' => __DIR__ . '/../view/layout/layout.phtml',
'front/index/index' => __DIR__ . '/../view/front/index/index.phtml',
'error/404' => __DIR__ . '/../view/error/404.phtml',
'error/index' => __DIR__ . '/../view/error/index.phtml',
),
'template_path_stack' => array(
__DIR__ . '/../view',
),
),
both's files are inside its module folder with same structure.
Q: How to prevent merging one module configuration from another?

Answer 1

You shouldn't prevent merging. There is a similar problem with loading different layout for 2 modules - take a look https://stackoverflow.com/a/11921330/949273
Unfortunately, Your issue is a bit contradictory because if you got a 404 page, there is no way to know what module is that - because of that it's called 404 page not found.
Anyway you can dispatch MvcEvent::EVENT_DISPATCH_ERROR event and check with regular expression URL and set different view file.
Code example
in your admin module config
'template_map' => array(
'error-admin/404' => __DIR__ . '/../view/error/404.phtml',
),
than on EVENT_DISPATCH_ERROR inject your logic
public function onBootstrap(MvcEvent $e)
{
$app = $e->getTarget();
$em = $app->getEventManager();
$em->attach(MvcEvent::EVENT_DISPATCH_ERROR, function (\Zend\Mvc\MvcEvent $e) {
$app = $e->getParam('application');
$uri = $app->getRequest()->getUri()->getPath();
if(strpos($uri, '/admin') === 0){
$view = new \Zend\View\Model\ViewModel();
$view->setTemplate('error-admin/404');
$e->setViewModel($view);
}
});
}

After lots of search I got the solution of my question.
Main problem was getting the Module name. here is my code.
I generated it with the help of MvcEvent::getRouteMatch()->getParam()
function boforeDispatch(MvcEvent $event) {
$controller = $event->getRouteMatch()->getParam('controller');
$request_module = substr($controller, 0, strpos($controller, '\\'));
if ($request_module == __NAMESPACE__) {
//do stuff
}
}
