Display product groups by color on the Storefront

To enhance the visual shopping experience of your customers, you can use product groups. A product group is a group of products logically united by an attribute. You can create product groups, but there is no way to display them on the Storefront by default. This guide shows how to display a product group on the Storefront using the color attribute as an example. The behavior to be configured is described in Product Groups feature overview.

Prerequisites

Integrate the Product Groups feature into your project.

Extend schema

In the database, add the color_code field to the spy_product_abstract table:

1. Create or extend the schema file as follows:

src/Pyz/Zed/ProductGroup/Persistence/Propel/Schema/spy_product.schema.xml

<?xml version="1.0"?>
<database xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="zed" xsi:noNamespaceSchemaLocation="http://xsd.propelorm.org/1.6/database.xsd" namespace="Orm\Zed\Product\Persistence" package="src.Orm.Zed.Product.Persistence">

    <table name="spy_product_abstract" idMethod="native" allowPkInsert="true" phpName="SpyProductAbstract">
        <column name="color_code" required="false" type="VARCHAR" default="NULL" size="8"/>
    </table>

</database>

2. Apply database changes and generate entity and transfer changes:

console transfer:generate
console propel:install
console transfer:generate

Extend transfer object

Extend the existing transfer objects to support the newly introduced colorCode field:

1. Create or extend the transfer object definition file as follows.

src/Pyz/Shared/ProductGroup/Transfer/product.transfer.xml

<?xml version="1.0"?>
<transfers xmlns="spryker:transfer-01"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="spryker:transfer-01 https://static.spryker.com/transfer-01.xsd">

    <transfer name="ProductAbstractStorage">
        <property name="colorCode" type="string"/>
    </transfer>

    <transfer name="ProductConcreteStorage">
        <property name="colorCode" type="string"/>
    </transfer>

    <transfer name="ProductView">
        <property name="colorCode" type="string"/>
    </transfer>
</transfers>

2. Generate transfer objects:

console transfer:generate

Extend product abstract data import

Extend the product abstract writer with the color code data in the data import module. In src/Pyz/Zed/DataImport/Business/Model/ProductAbstract/ProductAbstractWriterStep.php, edit ProductAbstractWriterStep as follows:

1. Introduce the KEY_COLOR_CODE constant.
2. Extend the importProductAbstract() method with the color code for the product abstract entity:

<?php

namespace Pyz\Zed\DataImport\Business\Model\ProductAbstract;

use Orm\Zed\Product\Persistence\SpyProductAbstract;
use Spryker\Zed\DataImport\Business\Model\DataImportStep\DataImportStepInterface;
use Spryker\Zed\DataImport\Business\Model\DataImportStep\PublishAwareStep;
use Spryker\Zed\DataImport\Business\Model\DataSet\DataSetInterface;

class ProductAbstractWriterStep extends PublishAwareStep implements DataImportStepInterface
{
    public const KEY_COLOR_CODE = 'color_code';

    /**
     * @param \Spryker\Zed\DataImport\Business\Model\DataSet\DataSetInterface $dataSet
     *
     * @return \Orm\Zed\Product\Persistence\SpyProductAbstract
     */
    protected function importProductAbstract(DataSetInterface $dataSet)
    {
        $productAbstractEntity = SpyProductAbstractQuery::create()
            ->filterBySku($dataSet[static::KEY_ABSTRACT_SKU])
            ->findOneOrCreate();

        $productAbstractEntity
            ->setColorCode($dataSet[static::KEY_COLOR_CODE])
            ->setFkTaxSet($dataSet[static::KEY_ID_TAX_SET])
            ->setAttributes(json_encode($dataSet[static::KEY_ATTRIBUTES]))
            ->setNewFrom($dataSet[static::KEY_NEW_FROM])
            ->setNewTo($dataSet[static::KEY_NEW_TO]);

        if ($productAbstractEntity->isNew() || $productAbstractEntity->isModified()) {
            $productAbstractEntity->save();
        }

        return $productAbstractEntity;
    }
}

Prepare demo data

Prepare the demo data for the color code field:

1. Add the color_code field to the product abstract data import. The following provided data can be used as an example:

data/import/icecat_biz_data/product_abstract.csv

>category_key,category_product_order,abstract_sku,name.en_US,name.de_DE,url.en_US,url.de_DE,is_featured,attribute_key_1,value_1,attribute_key_1.en_US,value_1.en_US,attribute_key_1.de_DE,value_1.de_DE,attribute_key_2,value_2,attribute_key_2.en_US,value_2.en_US,attribute_key_2.de_DE,value_2.de_DE,attribute_key_3,value_3,attribute_key_3.en_US,value_3.en_US,attribute_key_3.de_DE,value_3.de_DE,attribute_key_4,value_4,attribute_key_4.en_US,value_4.en_US,attribute_key_4.de_DE,value_4.de_DE,attribute_key_5,value_5,attribute_key_6,value_6,attribute_key_6.en_US,value_6.en_US,attribute_key_6.de_DE,value_6.de_DE,color_code,description.en_US,description.de_DE,icecat_pdp_url,tax_set_name,meta_title.en_US,meta_title.de_DE,meta_keywords.en_US,meta_keywords.de_DE,meta_description.en_US,meta_description.de_DE,icecat_license,new_from,new_to

2. Import abstract products with the newly introduced color_code field.

console data:import:product-abstract

Configure frontend

To change the product attribute used for grouping, in the src/Pyz/Yves/ProductGroupWidget/Theme/default/components/molecules/color-selector/color-selector.twig Twig template, redefine colorAttributeName.
