Global data storage in Zend Framework 2

Question

I would like to store data, eg. user name and surname to display them in many layouts. I want to set some variable in one controller and use it in layout.

Any solutions?

I created some similar layouts where i put:

<span id="STATUS">LOGGED: <span id="USERNAME"><?php echo $this->name. ' ' . $this->surname; ?></span>

But firstly, in some action of controller I get name and surname from database:

$db = $this->getServiceLocator()->get('MyDatabase'); $sql = 'SELECT * FROM Users'; $statement = $db->query($sql);/ $result = $statement->execute();

Then i set static variables in controller:

self::$name = $result['name']; self::$surname = $result['surname'];

Next in actions i change layout and pass variables to it:

$this->layout('layout/student'); $this->layout()->name = self::$name; $this->layout()->surname = self::$surname;

But I do not want get data from database in every controllers and pass variables in each of actions.

Okay my solution is this.

Inside your module.php

public function onBootstrap(MvcEvent $e)
{

    $sharedEvents = $e->getApplication()->getEventManager()->getSharedManager();
    $sharedEvents->attach(__NAMESPACE__, 'dispatch', function($e) {
    //This event will only be fired when an ActionController under the MyModule namespace is dispatched.
    $controller = $e->getTarget();

    //to be able to view actions and controllers
    $params = $e->getApplication()->getMvcEvent()->getRouteMatch()->getParams();
    $nameSurnameArray = $controller->getServiceLocator()->get('NAMEOFTABLEWITHSQL')->getNameSurname();
        if($params['action'] == 'test'){

        $controller->layout('layout/testlayout');
        $controller->layout()->name = $nameSurnameArray['name'];
        $controller->layout()->surname = $nameSurnameArray['surname']';
        }

    }, 100);

    $eventManager        = $e->getApplication()->getEventManager();
    $serviceManager      = $e->getApplication()->getServiceManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);
    $this->bootstrapSession($e);
}

So if the route is the Action test then testLayout is loaded and i pass to that layout the name and surname i got from database. Similarly you can specify a controller ($params['controller'] == 'testModule\\Controller\\testController') instead of an action if you have the same layout for one controller.

This solution can be improved i guess but hopefully it will point you to the right direction
