Magento 2 Add Customer Attribute Programmatically

As we all know Magento uses the EAV model structure for the customer attributes. So, in this article, I am going to explain to you how to create customer attributes programmatically in Magento 2.

First of all, you need to create one module. If you already have a module then go with that. If you are new to Magento then check our another article How To Create a Magento 2 Module.

Let's get started!!

Now I assume you already have a Magento 2 Module.

As we all know, now Magento 2 introduce a new way to modify data using Data Patches in Magento2. So, in this article, we'll create customer attributes using Data Patch in our Magento 2 Extension

Step 1: Create AddCustomerCustomAttribute.php file at app/code/Vendor/CustomerAttribute/Setup/Patch/Data and paste the below code.

saveCopyzoom_out_map
<?php
namespace Vendor\CustomerAttribute\Setup\Patch\Data;

use Magento\Customer\Model\Customer;
use Magento\Customer\Setup\CustomerSetup;
use Magento\Customer\Setup\CustomerSetupFactory;
use Magento\Eav\Model\Entity\Attribute\Set;
use Magento\Eav\Model\Entity\Attribute\SetFactory;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\Patch\DataPatchInterface;
use Magento\Framework\Setup\Patch\PatchRevertableInterface;

class AddCustomerCustomAttribute implements DataPatchInterface, PatchRevertableInterface
{

    /**
     * @var ModuleDataSetupInterface
     */
    private $moduleDataSetup;
    /**
     * @var CustomerSetup
     */
    private $customerSetupFactory;
    /**
     * @var SetFactory
     */
    private $attributeSetFactory;

    /**
     * Constructor
     *
     * @param ModuleDataSetupInterface $moduleDataSetup
     * @param CustomerSetupFactory $customerSetupFactory
     * @param SetFactory $attributeSetFactory
     */
    public function __construct(
        ModuleDataSetupInterface $moduleDataSetup,
        CustomerSetupFactory     $customerSetupFactory,
        SetFactory               $attributeSetFactory
    )
    {
        $this->moduleDataSetup = $moduleDataSetup;
        $this->customerSetupFactory = $customerSetupFactory;
        $this->attributeSetFactory = $attributeSetFactory;
    }

    /**
     * {@inheritdoc}
     */
    public function apply()
    {
        $this->moduleDataSetup->getConnection()->startSetup();
        /** @var CustomerSetup $customerSetup */
        $customerSetup = $this->customerSetupFactory->create(['setup' => $this->moduleDataSetup]);
        $customerEntity = $customerSetup->getEavConfig()->getEntityType(Customer::ENTITY);
        $attributeSetId = $customerEntity->getDefaultAttributeSetId();

        /** @var $attributeSet Set */
        $attributeSet = $this->attributeSetFactory->create();
        $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);

        $customerSetup->addAttribute(
            Customer::ENTITY,
            'custom_new_attribute',
            [
                'label' => 'Custom New Attribute',
                'input' => 'text',
                'type' => 'varchar',
                'source' => '',
                'required' => false,
                'position' => 40,
                'visible' => true,
                'system' => false,
                'is_used_in_grid' => true,
                'is_visible_in_grid' => true,
                'is_filterable_in_grid' => true,
                'is_searchable_in_grid' => false,
                'backend' => ''
            ]
        );

        $attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'custom_new_attribute');
        $attribute->addData([
            'used_in_forms' => [
                'adminhtml_customer',
                'customer_account_create',
                'customer_account_edit'
            ]
        ]);
        $attribute->addData([
            'attribute_set_id' => $attributeSetId,
            'attribute_group_id' => $attributeGroupId

        ]);
        $attribute->save();

        $this->moduleDataSetup->getConnection()->endSetup();
    }

    public function revert()
    {
        $this->moduleDataSetup->getConnection()->startSetup();
        /** @var CustomerSetup $customerSetup */
        $customerSetup = $this->customerSetupFactory->create(['setup' => $this->moduleDataSetup]);
        $customerSetup->removeAttribute(\Magento\Customer\Model\Customer::ENTITY, 'custom_new_attribute');

        $this->moduleDataSetup->getConnection()->endSetup();
    }

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

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

In the above code, we have created a text type attribute. Replace, custom_new_attribute with your attribute code and change the label and another attribute settings as per your need.

Step 2: Open Command line in folder root of magento and run commands for create new customer attribute programmatically.

saveCopyzoom_out_map
php bin/magento setup:upgrade

php bin/magento cache:flush

php bin/magento indexer:reindex

Bingo!! we are done, now go to the Admin > Customer > Edit Customer > Account Information > And find your attribute in our case it's Custom New Attribute. Newly created attribute will display like the below screenshot.

That's it!!
