Built-in menus

With the ibexa\storefront package come the following built-in menus:

Item Value Description
Breadcrumbs - Renders breadcrumbs for Content Tree Root, Taxonomy Entry, Product, User settings and User settings group
Taxonomy - It can render a menu for product categories or tags
Currency currency_menu Renders a menu to change the active currency
Language language_menu Renders a menu to change the active language
Region region_menu Renders a menu to change the active region

Usage example:

1
2
3
{% set currency_menu = knp_menu_get('ibexa_storefront.menu.currency') %}

{{ knp_menu_render(currency_menu) }}

To modify the items in the menu, you need to use an event subscriber. This subscriber replaces the URI under the Home link.

Create an event subscriber in src/EventSubscriber/BreadcrumbsMenuSubscriber.php:

 1
 2
 3
 4
 5

 7
 8
 9
10
11

<?php

declare(strict_types=1);

namespace App\EventSubscriber;

use Ibexa\Bundle\Storefront\Menu\Builder\BreadcrumbsMenuBuilder;
use Ibexa\Contracts\Storefront\Menu\Event\ConfigureMenuEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class BreadcrumbsMenuSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents()
    {
        return [
            BreadcrumbsMenuBuilder::PRODUCT_MENU => ['onBreadcrumbsMenuConfigure', 0],
        ];
    }

    public function onBreadcrumbsMenuConfigure(ConfigureMenuEvent $event): void
    {
        $menu = $event->getMenu();

        // Replace link to home with link to product catalog root
        $menu->getChild('location_2')->setUri('/product-catalog');
    }
}

Next, create the templates/themes/storefront/storefront/knp_menu/breadcrumbs.html.twig template:

 1
 2
 3

 5

 7
 8
 9

{% extends 'knp_menu.html.twig' %}

{% block item %}
    {% if item.displayed %}
        {%- set attributes = item.attributes %}
        {% import _self as knp_menu %}
        <li{{ knp_menu.attributes(attributes) }}>
            {%- if item.uri is not empty and (not matcher.isCurrent(item) or options.currentAsLink) %}
                {{ block('linkElement') }}
            {%- else %}
                {{ block('spanElement') }}
            {%- endif %}
        </li>
    {% endif %}
{% endblock %}

{% block linkElement %}
    {%- set classes = ['breadcrumb_link'] -%}

    <a href="{{ item.uri }}" {{ _self.attributes({ class: classes|join(' ') }) }}>
        {{ block('label') }}
    </a>

{% endblock %}

Next, extend the templates/themes/storefront/storefront/product.html.twig template to include the breadcrumbs:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

{% extends no_layout == true ? view_base_layout : page_layout %}

{% trans_default_domain 'storefront' %}

{% block content %}
    {% set breadcrumbs_menu = knp_menu_get('ibexa_storefront.menu.breadcrumbs.product', [], {
        'product': product        
    }) %}

    {{ knp_menu_render(breadcrumbs_menu, {
        template: '@ibexadesign/storefront/knp_menu/breadcrumbs.html.twig',
    }) }}

    {% include '@ibexadesign/storefront/component/product_view.html.twig' %}
{% endblock %}

{% block javascripts %}
    {{ parent() }}
{% endblock %}

Taxonomy menu

You can build a taxonomy menu for, for example, product categories or tags.

See the usage example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
{% set categories_menu = knp_menu_get(
    'ibexa_storefront.menu.taxonomy', 
    [], 
    {
        parent: category,
        depth: 3
    }
) %}

{{ knp_menu_render(categories_menu) }}

It takes the following parameters:

Name Type Default
parent \Ibexa\Contracts\Taxonomy\Value\TaxonomyEntry The root entry of the specified taxonomy.
depth int Default: 1
taxonomy_name string product_categories

Create menu items

\Ibexa\Contracts\Storefront\Menu\ItemFactoryInterface provides convenient methods to build menu item based on repository objects, including:

  • Content
  • Content ID
  • Location
  • Location ID
  • Taxonomy Entry
  • Product

Generate custom product preview path

By default, the ProductRenderController controller passes only the product object for rendering. You can modify the controller file to make it pass parameters to the path Twig helper function, which is used by the product_card.html.twig and product_card.html.twig templates to generate the user path. After you modify the controller, it can also pass the following parameters:

  • route - the route, under which product preview is available.
  • parameters - parameters to be used, for example, to render the view.
  • is_relative - Boolean that decides whether the URL is relative or absolute.

Define your own logic in a custom controller. Refer to the code snippet below and create your own file, for example, CustomProductRenderController.php:

1
2
3
4
5
6
7
8
9
    public function renderAction(ProductInterface $product): Response
    {
        return $this->render('@ibexadesign/storefront/product_card.html.twig', [
            'content' => $product,
            'route' => 'some.path',
            'parameters' => ['some.parameter' => 123],
            'is_relative' => true,
        ]);
    }
