ZF2将代码从module.config.php移动到module.php

Question

I've found on the web a way to declare a custom Navigation Menu using the following:

module.config.php in Acl module:

'navigation_helpers' => array(
    'invokables' => array(
        'menu' => 'Acl\View\Helper\Navigation\Menu',
    )
),

Now I'd like to pass a parameter to the custom Menu constructor. I'm quite new in ZF2 world but it seems that I have to create some kind of service in the module.php file. I've tried to put code into getServiceConfig and getViewHelperConfig methods without success (the custom menu is not "used").

Any idea/hint of the array structure and the method I should use?

Thanks a lot,

To do this you should register your menu as a factory and then you can pass parameters to the menu when instantiating the class inside the factory:

Create a MenuFactory class:

<?php

namespace Acl\View\Helper\Navigation\Factory;

/**
 * Factory to create menu
 */
class MenuFactory implements FactoryInterface
{
    /**
     * {@inheritDoc}
     * @return Menu
     */
    public function createService(ServiceLocatorInterface $serviceLocator)
    {
        $param = // get your param from servicelocator or create the parameter
        $menu = new Menu($param);
        return $menu;
    }
}

Now you register your menu as a factory instead of as an invokable:

'navigation_helpers' => array(
    'factories' => array(
        'menu' => 'Acl\View\Helper\Navigation\Factory\MenuFactory',
    )
),
