README

The package provides object-oriented menus for projects based on the Spiral Framework.

Requirements

Make sure that your server is configured with following PHP version and extensions:

• PHP 8.1+
• Spiral framework 3.5+

Installation

You can install the package via composer:

composer require zentlix/knp-menu

To enable the package, you just need to add Spiral\KnpMenu\Bootloader\KnpMenuBootloader to the bootloaders list, which is located in the class of your application.

protected const LOAD = [
    // ...
    \Spiral\KnpMenu\Bootloader\KnpMenuBootloader::class,
];

Note If you are using spiral-packages/discoverer, you don't need to register bootloader by yourself.

Configuration

The configuration file for this package should be located at app/config/knp-menu.php. Within this file, you may configure default template and template_options for all menus. Also, you can register menus.

For example, the configuration file might look like this.

use App\Menu\Sidebar;
use App\Menu\TopBar;
use App\Menu\OtherMenu;
use Spiral\Core\Container\Autowire;

return [
    /**
     * -------------------------------------------------------------------------
     *  Default template for all menus
     * -------------------------------------------------------------------------
     */
    'template' => 'menu.twig',

    /**
     * -------------------------------------------------------------------------
     *  Template options for all menus
     * -------------------------------------------------------------------------
     */
    'template_options' => [
        'foo' => 'bar'
    ],

    /**
     * -------------------------------------------------------------------------
     *  Application menus list
     * -------------------------------------------------------------------------
     *
     *  As a key, you can specify the name of the menu, using this key you can get the menu.
     *  If the key is not specified, the fully qualified name of the class will be used as the key.
     */
    'menus' => [
        'sidebar' => Sidebar::class,
        'top-bar' => new Autowire(TopBar::class),
        'other' => new OtherMenu()
    ]
];

Creating a menu

To create a menu, create a class and implement interface Spiral\KnpMenu\MenuInterface.

namespace App\Menu;

use Knp\Menu\FactoryInterface;
use Knp\Menu\ItemInterface;
use Spiral\KnpMenu\MenuInterface;

final class Sidebar implements MenuInterface
{
    public function __construct(
        private readonly FactoryInterface $factory
    ) {
    }

    public function create(array $options = []): ItemInterface
    {
        $menu = $this->factory->createItem('root');

        $menu->addChild('Home', ['route' => 'homepage']);
        $menu->addChild('Blog', ['uri' => '/posts']);
        $menu->addChild('Comments', ['uri' => '#comments']);
        $menu->addChild('Full URL', ['uri' => 'https://site.com/']);

        return $menu;
    }
}

After that, you can register the menu in the config file as shown above, or register it using Spiral\KnpMenu\MenuRegistry.

namespace App\Bootloader;

use App\Menu\Sidebar;
use Spiral\Boot\Bootloader\Bootloader;
use Spiral\KnpMenu\Bootloader\KnpMenuBootloader;
use Spiral\KnpMenu\MenuRegistry;

final class MenuBootloader extends Bootloader
{
    protected const DEPENDENCIES = [
        KnpMenuBootloader::class
    ];

    public function boot(MenuRegistry $registry, Sidebar $menu): void
    {
        $registry->add('sidebar', $menu);
    }
}

Using

If you are using Twig, you can use the knp_menu_render extension to render the menu.

{{ knp_menu_render('sidebar') }}

With custom template or other options.

{{ knp_menu_render('sidebar', {'template': 'custom.twig'}) }}

Warning To use other templating engines, need to implement the menu display mechanism yourself.
