How to Add Product Attribute Programmatically in Magento 2 • Devhooks

As we all know Magento use the EAV model structure for product attributes. And in this article I am going to explain how to create product attribute programmatically in Magento 2.

First of all you need to create one module. If you already have a module then go with that but don't forget to change the setup version and if you are new in Magento then check our another article How To Create a Magento 2 Module.

Let's get started!!

Now I assume you already have magento module.

To create the product attribute programmatically in module we need to create InstallData class in our Magento 2 Extension

Let's Create InstallData.php file at app/code/Devhooks/HelloWorld/Setup/InstallData.php and paste the below code.

saveCopyzoom_out_map<?php
namespace Devhooks\HelloWorld\Setup;

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'custom_attribute',
            [
                'type' => 'text',
                'backend' => '',
                'frontend' => '',
                'label' => 'Custom Atrribute',
                'input' => 'text',
                'class' => '',
                'source' => '',
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                'visible' => true,
                'required' => true,
                'user_defined' => false,
                'default' => '',
                'searchable' => false,
                'filterable' => false,
                'comparable' => false,
                'visible_on_front' => false,
                'used_in_product_listing' => true,
                'unique' => false,
                'apply_to' => ''
            ]
        );
    }
}

In above code we have create a text type attribute. Replace, custom_attribute with your attribute code and change the lable and other attribute setting as per your need.

Now, open Command line in folder root of magento and run both commands for create new product attribute programmatically.

saveCopyzoom_out_mapphp bin/magento setup:upgrade

php bin/magento cache:flush

php bin/magento indexer:reindex

Bingo!! we are done, now go to the Admin > Store > Attributes > Product and find your attribute.

That's it!!
