Add custom product attributes for different product types in Magento2

In this blog, we are going to learn how we can add custom product attributes for different product types.

Example:- Custom Attribute 1 for Simple Product, Custom Attribute 2 for Configurable Product, Custom Attribute 3 for Bundle Product, and so on for other Products.

Here, in the following example, I have added some custom attributes for different product types.

Please follow the below steps to achieve the desired result.

Step 1: Create CustomProductAttributes.php file inside the app/code/Vendor/Module/Setup/ Patch/Data/ directory.

namespace Webkul\CustomProductAttributes\Setup\Patch\Data;

use Magento\Framework\Setup\Patch\DataPatchInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Eav\Model\Config as EavConfig;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Eav\Model\Entity\Attribute\SetFactory;
use Magento\Catalog\Model\Product;
use Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface;

class CustomProductAttributes implements DataPatchInterface
{
    /**

    private $moduleDataSetup;

    private $eavConfig;

    /**

    private $eavSetupFactory;
    
    /**

    private $attributeSetFactory;

    /**

    public function __construct(
        ModuleDataSetupInterface $moduleDataSetup,
        EavConfig $eavConfig,
        EavSetupFactory $eavSetupFactory,
        SetFactory $attributeSetFactory
    ) {
        $this->moduleDataSetup = $moduleDataSetup;
        $this->eavConfig = $eavConfig;
        $this->eavSetupFactory = $eavSetupFactory;
        $this->attributeSetFactory = $attributeSetFactory;
    }

    /**

        $this->moduleDataSetup->getConnection()->startSetup();

        $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);
        /** creating attribute for simple products  */
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'custom_attr_simple',
            [
                'type' => 'text',
                'backend' => '',
                'frontend' => '',
                'label' => 'Custom Attribute 1',

                'apply_to' => 'simple'
            ]
        );

        /** creating attribute for configurable products */
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'custom_attr_configurable',
            [

                'visible' => true,
                'required' => false,
                'user_defined' => false,
                'default' => '',
                'searchable' => false,

                'used_in_product_listing' => true,
                'unique' => false,
                'apply_to' => 'configurable'
            ]
        );

        /** creating attribute for bundle products */
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'custom_attr_bundle',
            [
                'type' => 'text',
                'backend' => '',
                'frontend' => '',
                'label' => 'Custom Attribute 3',
                'input' => 'text',

                'source' => '',
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                'visible' => true,
                'required' => false,
                'user_defined' => false,
                'default' => '',
                'searchable' => false,
                'filterable' => false,
                'comparable' => false,
                'visible_on_front' => false,
                'used_in_product_listing' => true,
                'unique' => false,
                'apply_to' => 'bundle'
            ]
        );
    }

    /**
     * @inheritdoc
     */
    public function getAliases()
    {
        return [];
    }

    /**
     * @inheritdoc
     */
    public static function getDependencies()
    {
        return [];
    }
}

Step 2: Now, just run the below upgrade command.

php bin/magento setup:upgrade

Now, look into the first image in which Custom Attribute 1 is being displayed for Simple Products Only.

Look into the second image in which Custom Attribute 2 is being displayed for Configurable Products only.

And in the last image in which Custom Attribute 3 is being displayed for Bundle Products only.

Hope this will be helpful.

Thanks 🙂
