Build your own product relation type

This tutorial shows how to build your own product relation type.

Modify Zed

1. Create a new relation type in \Spryker\Shared\ProductRelation\ProductRelationTypes as a new constant type—for example, TYPE_RELATION_NEW.
2. Include this relation type to getAvailableRelationTypes returned array.
3. Select a new relation type when building a relation. For example, for Yves, you need to create a custom data provider:

<?php

class RelationNewDataProvider implements ProductRelationDataProviderInterface
{
    /**
     * @param array $parameters
     *
     * @return array|\Generated\Shared\Transfer\StorageProductAbstractRelationTransfer[]
     */
    public function buildTemplateData(array $parameters)
    {
       //read data from Yves data store, return data for the view to render.
    }      

    /**
    * @return string
    */
   public function getAcceptedType()
   {
     return ProductRelationTypes::TYPE_RELATION_NEW; //this is the type which is mapped when rendering twig function, first argument.
   }  
}

Modify Yves

By default, the demoshop provides a carousel-type JavaScript component which renders related products. This component can be added with a twig product_relation (type, parameters, title, templatePath) function.

The type is a string that maps to a specific data provider and provides custom data when used, like a related product or upselling.

It accepts the following arguments:

Each type has a data provider. This data provider reads data from Redis and sends it to the template.
