Zend 2错误：未捕获的异常'Zend \ Stdlib \ Exception \ InvalidArgumentException'

Question

I retrieve data from Zend 2 session container on layout via bootstarp method.

public function onBootstrap(MvcEvent $e)
{
    $eventManager        = $e->getApplication()->getEventManager();
    $sm = $e->getApplication()->getServiceManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);

    $user = $this->getUser($sm);
    $viewModel = $e->getApplication()->getMvcEvent()->getViewModel();
    $viewModel->user = ($user) ? $user: false;
}

public function getUser($sm)
{
    $user= false;
    $userTable= $sm->get('User\Model\UserTable');
    $userSession = new Container('userSession');

    //RETRIEVE USER FROM DB

    return $user;
}

Now i'm getting following error sometimes (not always)

Fatal error: Uncaught exception 'Zend\Stdlib\Exception\InvalidArgumentException' with message 'Passed variable is not an array or object, using empty array instead' in /var/www/T2oRecruitment/app/vendor/zendframework/zendframework/library/Zend/Stdlib/ArrayObject.php:184 Stack trace: #0

What is the issue ?

Answer 1

Please try with this:

In Module.php file --->

use Zend\Session\Config\SessionConfig, Zend\Session\SessionManager,
    Zend\Session\Container, Zend\Mvc\MvcEvent;
// other libraries

public function onBootstrap(MvcEvent $e)
{
    $eventManager        = $e->getApplication()->getEventManager();
    $sm = $e->getApplication()->getServiceManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);

    $config = $sm->get('Config');

    $sessionConfig = new SessionConfig();
    $sessionConfig->setOptions($config['session']);
    $sessionManager = new SessionManager($sessionConfig);
    $sessionManager->start();

    $user = $this->userSession($sm);
    $viewModel = $e->getApplication()->getMvcEvent()->getViewModel();
    $viewModel->user = ($user) ? $user: false;
}

In module.config.php file --->

return array(
    'session' => array(
        'remember_me_seconds' => 2419200,
        'use_cookies' => true,
        'cookie_httponly' => true
    ),
);

Hope, this will give some idea to you, for fixing your issue. Thanks :)
