Catalog Models

This reference documents all Twig-accessible properties and methods for catalog organization models: categories, manufacturers, and custom groups. These models are typically accessed via the Catalog component.

`fullslug`	`string`	Full URL path including parents (e.g., `electronics/phones`)
`baseid`	`string`	Base identifier
`code`	`string`	Category code for programmatic reference
`title`	`string`	SEO/page title (falls back to `name`)
`description`	`string`	Full description (HTML)
`short_description`	`string`	Brief summary
`is_hidden`	`bool`	Whether hidden from frontend
`sort_order`	`int`	Display order
`parent_id`	`int\|null`	Parent category ID

`priceRange()`	`array`	`{min, max}` base values (cents) for products in this category
`getBreadcrumbPath()`	`array\|null`	Parent chain for breadcrumbs
`getParents()`	`array`	All ancestor categories

Scopes

Scope	Description
`applyVisible`	Filters out hidden categories

listProducts Options

The listProducts() method returns a paginated collection with these options:

Option	Type	Default	Description
`page`	`int`	`1`	Page number
`perPage`	`int`	`30`	Products per page
`sorting`	`string`	`created_at`	Sort field: `created_at`, `price`, `name`, `random`

Accessing Manufacturers

The catalog component supports manufacturer lookup:

ini

[catalog]
lookup = "manufacturer"
identifier = "slug"

This sets the manufacturer page variable, giving you access to all manufacturer properties and its products.

Complete Examples

Manufacturer Page

twig

title = "Manufacturer"
url = "/shop/manufacturer/:slug"

[catalog]
lookup = "manufacturer"
identifier = "slug"
==
{% if not manufacturer %}
    {% do abort(404) %}
{% endif %}

<div class="manufacturer-detail">
    {% if manufacturer.logo %}
        <img src="{{ manufacturer.logo.path|resize(300, 200) }}"
             alt="{{ manufacturer.name }}" />
    {% endif %}

    <h1>{{ manufacturer.name }}</h1>

    {% if manufacturer.description %}
        <div>{{ manufacturer.description|raw }}</div>
    {% endif %}

    {% if manufacturer.website_url %}
        <a href="{{ manufacturer.website_url }}" target="_blank">
            Visit Website
        </a>
    {% endif %}

    <h2>Products by {{ manufacturer.name }}</h2>
    <div class="product-grid">
        {% for product in manufacturer.products %}
            {% partial 'shop/product-card' product=product %}
        {% endfor %}
    </div>
</div>

Manufacturer Info on Product Page

twig

{% if product.manufacturer %}
    <div class="manufacturer-info">
        {% if product.manufacturer.logo %}
            <img src="{{ product.manufacturer.logo.path|resize(100, 60) }}"
                 alt="{{ product.manufacturer.name }}" />
        {% endif %}
        <a href="{{ 'shop/manufacturer'|page({ slug: product.manufacturer.slug }) }}">
            {{ product.manufacturer.name }}
        </a>
    </div>
{% endif %}

Manufacturer List

twig

[catalog]
==
{% set manufacturers = catalog.customGroupQuery() %}
{# Or query directly: #}

<h1>Our Brands</h1>
<div class="brand-grid">
    {% for manufacturer in manufacturers %}
        <a href="{{ 'shop/manufacturer'|page({ slug: manufacturer.slug }) }}">
            {% if manufacturer.logo %}
                <img src="{{ manufacturer.logo.path|resize(200, 120) }}"
                     alt="{{ manufacturer.name }}" />
            {% endif %}
            <span>{{ manufacturer.name }}</span>
        </a>
    {% endfor %}
</div>

CustomGroup

Custom groups are curated, flat collections of products used for specific sections of your site — featured products, new arrivals, best sellers, etc. Products within a group can be manually sorted.

Core Properties

Property	Type	Description
`id`	`int`	Primary key
`name`	`string`	Group name
`code`	`string`	Unique code for template lookup
`created_at`	`Carbon`	Creation date
`updated_at`	`Carbon`	Last update date

Relationships

Property	Type	Description
`products`	`Collection<Product>`	Products in this group (sorted by `sort_order`)

Accessing Custom Groups

Use the catalog component's findCustomGroup() method to look up a group by its code:

twig

{% set group = catalog.findCustomGroup('featured-products') %}

Or use customGroupQuery() to query all groups:

twig

{% set groups = catalog.customGroupQuery().get() %}

Complete Examples

Featured Products Section

twig

{% set featured = catalog.findCustomGroup('featured-products') %}
{% if featured and featured.products is not empty %}
    <section class="featured-products">
        <h2>Featured Products</h2>
        <div class="product-grid">
            {% for product in featured.products %}
                {% partial 'shop/product-card' product=product %}
            {% endfor %}
        </div>
    </section>
{% endif %}

Multiple Groups on Homepage

twig

{% set featured = catalog.findCustomGroup('featured') %}
{% set newArrivals = catalog.findCustomGroup('new-arrivals') %}
{% set bestSellers = catalog.findCustomGroup('best-sellers') %}

{% for group in [featured, newArrivals, bestSellers] %}
    {% if group and group.products is not empty %}
        <section>
            <h2>{{ group.name }}</h2>
            <div class="product-grid">
                {% for product in group.products %}
                    {% partial 'shop/product-card' product=product %}
                {% endfor %}
            </div>
        </section>
    {% endif %}
{% endfor %}

Commerce Theme Custom Group Partial

The commerce theme includes a reusable shop/custom-group partial:

twig

{% partial 'shop/custom-group' groupCode='featured-products' %}

This partial looks up the group by code and renders a product grid. If the group doesn't exist, it displays a message prompting you to create it in the backend.

Querying Products

Both categories and custom groups give you access to product collections, but for more advanced queries, use the catalog component's query builders.

Product Query Builder

twig

{# Custom product query #}
{% set products = catalog.productQuery()
    .applyVisible()
    .where('is_on_sale', true)
    .orderBy('price', 'asc')
    .limit(8)
    .get() %}

{% for product in products %}
    {% partial 'shop/product-card' product=product %}
{% endfor %}

Category Query Builder

twig

{# All top-level categories #}
{% set topLevel = catalog.categoryQuery()
    .applyVisible()
    .whereNull('parent_id')
    .orderBy('sort_order')
    .get() %}

Custom Group Query Builder

twig

{# All custom groups #}
{% set groups = catalog.customGroupQuery().get() %}
{% for group in groups %}
    <h3>{{ group.name }} ({{ group.products.count() }} products)</h3>
{% endfor %}
