Magento2: How to add a new product type

Question

This new product type will contain parent informations of other products. These products are only for internal use, so I only need to add attributes and a new type of relation to other products, like Up-Sells, Cross-Sells. All other default informations like prices, description, etc. are not needed.

What is the best way to create this product type.

Answer 1

Step 1: Generate the app\code\Vendor\Module\registration.php file

Setup the app\code\Vendor\Module\registration.php file

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Vendor_Module',
    __DIR__
);

Generate the app\code\Vendor\Module\etc\module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Vendor_Module" setup_version="1.0.0">

    </module>
</config>

Next, the creation of the etc/product_types.xml file is necessary to determine the model of the new product type.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/product_types.xsd">
    <type name="new_product_type" label="New Product Type" modelInstance="Vendor\Module\Model\Product\Type\NewProductType" indexPriority="60" sortOrder="80" isQty="true">
        <priceModel instance="Vendor\Module\Model\Product\Price" />
    </type>
</config>

Step 2: Enter the code : Vendor\Module\Model\Product\Type\NewProductType model

Enter the code below: Vendor\Module\Model\Product\Type\NewProductType model, that should be based on Magento\Catalog\Model\Product\Type\AbstractType.

<?php

namespace Vendor\Module\Model\Product\Type;

class NewProductType extends \Magento\Catalog\Model\Product\Type\AbstractType 
{

}

After that, it is possible to rewrite some functions and implement some changes you want there.

Step 3: Enter the Vendor\Module\Model\Product\Price model

Enter Vendor\Module\Model\Product\Price model, which should be based on the Magento\Catalog\Model\Product\Type\Price.

<?php
 namespace Vendor\Module\Model\Product;
 class Price extends \Magento\Catalog\Model\Product\Type\Price
 {

 }

Besides, you can also set the new product type as versatile type with some custom functions after extending the Magento\Catalog\Model\Product\Type\Price class

Step 4: Public the new Magento 2 Product type

This is the step allowing you to check the result in the Magento 2 Administrator when completing the above steps. The New Product type will display as the old types (Simple or Configurable Product).

I hope this will help
