How to Create Product Attribute Programmatically in Magento 2

In this tutorial, Today I will explain to how to create product attribute programmatically in Magento 2. To create product attribute, we need to create InstallData.php file in your custom module. Magento 2 Product Structure follows EAV structure. So, we can not create new attribute from database table.

When, you will setup your module at that time, InstallData file will execute and create new product attribute. After that, To see that attribute in product edit form you need to set that attribute in appropriate attribute set and save that attribute set.

First of all, you should have your own Magento 2 Extension. See how to create your module here.

Let’s follow the below steps to Create Product Attribute Programmatically in Magento 2.

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
{
    /**
     * @var EavSetupFactory
     */
    private $eavSetupFactory;

    /**
     * @param EavSetupFactory $eavSetupFactory
     */
    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }
    
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(
            Product::ENTITY,
            'product_temp_attribute',
            [
                'type' => 'text',
                'backend' => '',
                'frontend' => '',
                'label' => 'Product Temp Atrribute',
                'input' => 'text',
                'class' => '',
                'source' => '',
                'global' => 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' => ''
            ]
        );
    }
}

2) After that, you need to upgrade your module using below command :

Copy Code


php bin/magento s:up
php bin/magento s:s:d -f
php bin/magento c:c

That’s it !!!

You can check this custom attribute in eav_attribute table that attribute creates successfully or not.
