I'm using sumfony 3.3.10, I have installed a fresh project of symfony and I added knpMenuBundle using this command,
composer require knplabs/knp-menu-bundle "^2.0"
Now I followed everything exactly as mentioned here http://symfony.com/doc/master/bundles/KnpMenuBundle/menu_builder_service.html
and added this line {{ knp_menu_render('main') }} in default/index.html.twig file.
Now when I execute the project, its showing me this error,
[InvalidArgumentException]
Menu builder services must be public but "app.menu_builder" is a private service.
config.yml
knp_menu:
# use "twig: false" to disable the Twig extension and the TwigRenderer
twig:
template: KnpMenuBundle::menu.html.twig
# if true, enables the helper for PHP templates
templating: false
# the renderer to use, list is also available by default
default_renderer: twig
MenuBuilder.php
<?php
namespace AppBundle\Menu;
use Knp\Menu\FactoryInterface;
class MenuBuilder
{
private $factory;
/**
* @param FactoryInterface $factory
*
* Add any other dependency you need
*/
public function __construct(FactoryInterface $factory)
{
$this->factory = $factory;
}
public function createMainMenu(array $options)
{
$menu = $this->factory->createItem('root');
$menu->addChild('Home', array('route' => 'homepage'));
// ... add more children
return $menu;
}
}
services.yml
app.menu_builder:
class: AppBundle\Menu\MenuBuilder
arguments: ["@knp_menu.factory"]
tags:
- { name: knp_menu.menu_builder, method: createMainMenu, alias: main } # The alias is what is used to retrieve the menu
How can I resolve it. Any help is much appreciated. Thanks
I added public: true to the app.menu_builder service in services.php,
app.menu_builder:
class: AppBundle\Menu\MenuBuilder
public: true
arguments: ["@knp_menu.factory"]
tags:
- { name: knp_menu.menu_builder, method: createMainMenu, alias: main } # The alias is what is used to retrieve the menu
And everything is working fine now.
