What is KnpMenu?

The KnpMenu library provides object oriented menus for PHP 5.3. With following API.

<?php

use Knp\Menu\MenuFactory;
use Knp\Menu\Renderer\ListRenderer;

$factory = new MenuFactory();
$menu = $factory->createItem('My menu');
$menu->addChild('Home', array('uri' => '/'));
$menu->addChild('Comments', array('uri' => '#comments'));
$menu->addChild('Symfony2', array('uri' => 'http://symfony-reloaded.org/'));
$menu->addChild('Coming soon');

$renderer = new ListRenderer();
echo $renderer->render($menu);

The above menu would render the following HTML:

<ul>
  <li class="first">
    <a href="/">Home</a>
  </li>
  <li class="current">
    <a href="#comments">Comments</a>
  </li>
  <li>
    <a href="http://symfony-reloaded.org/">Symfony2</a>
  </li>
  <li class="last">
    <span>Coming soon</span>
  </li>
</ul>

This way you can finally avoid writing an ugly template to show the selected item, the first and last items, submenus, ...

Usage

Extension adds factory for the menu control, so in presenter is usable like this:

abstract class BasePresenter extends Presenter
{
    /** @var Menu\Control\Factory */
    private $menuFactory;

    public function injectMenuFactory(Menu\Control\Factory $factory)
    {
        $this->menuFactory = $factory;
    }

    protected function createComponentMenu()
    {
        $menu = $this->menuFactory->createControl();
        $root = $menu->getRoot();

        $root->addChild('catalog', array(
           'label' => 'Katalog',
           'icon'  => 'book'
        ));

        $root['catalog']->addChild('categories', array(
            'label' => 'Categories',
            'link'  => 'Category:list',
            'icon'  => 'table',
        ));

        $root['catalog']->addChild('new', array(
            'label' => 'Product',
            'link'  => 'Product:list',
            'icon'  => 'gift',
        ));
         
        // ....

        return $menu;
    }
    // ...
}

and then in your template you can use obligate control macro:

{control menu}

Renderers

You can register as many renderers as you want. Some default renderers are registered by defaul:

list          => Smf\Menu\Renderer\ListRenderer
bootstrapNav  => Smf\Menu\Renderer\BootstrapNavRenderer

You can use them in template

{control menu:list}
{control menu:bootstrapNav}

Registration of new renderer is as easy as adding new service to your config with tag menuRenderer:

services:
    myRenderer: 
         class: My\Super\Renderer
         tags: 
             menuRenderer: mySuperRenderer

And then you can use it:

{control menu:mySuperRenderer}
