This article will guide you on how to add customer attributes in Magento 2 programmatically. Please follow our previous article to create a simple module that we will use to demo coding for this lesson and how to create the setup script classes.

Overview of Adding Customer Attribute Programmatically

Step 1: Create setup file InstallData.php
Step 2: Define the install() method
Step 3: Create custom attribute

Step 1: Create setup file InstallData.php

Firstly, we will create the InstallData.php file:

File: app/code/Mageplaza/HelloWorld/Setup/InstallData.php

<?php
namespace Mageplaza\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;
	}

}

In this class, we define the EAV setup model which will be used to interact with the Magento 2 attribute.

Step 2: Define the install() method

After that, we have to define the install() method and create eav setup model:

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
	{
		$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
	}
	Next, we will use eavSetup object to add attribute:
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
	{
		$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
		$eavSetup->addAttribute(
			\Magento\Customer\Model\Customer::ENTITY,
			'sample_attribute',
			[
				'type'         => 'varchar',
				'label'        => 'Sample Attribute',
				'input'        => 'text',
				'required'     => false,
				'visible'      => true,
				'user_defined' => true,
				'position'     => 999,
				'system'       => 0,
			]
		);
}

Step 3: Create custom attribute

Finally, we need to set the forms in which the attributes will be used. In this step, we need to define the eavConfig object which allows us to call the attribute back and set the data for it. And the full code to create customer attributes is:

File: app/code/Mageplaza/HelloWorld/Setup/InstallData.php

<?php

namespace Mageplaza\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;
use Magento\Eav\Model\Config;
use Magento\Customer\Model\Customer;

class InstallData implements InstallDataInterface
{
	private $eavSetupFactory;

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

	public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
	{
		$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
		$eavSetup->addAttribute(
			\Magento\Customer\Model\Customer::ENTITY,
			'sample_attribute',
			[
				'type'         => 'varchar',
				'label'        => 'Sample Attribute',
				'input'        => 'text',
				'required'     => false,
				'visible'      => true,
				'user_defined' => true,
				'position'     => 999,
				'system'       => 0,
			]
		);
		$sampleAttribute = $this->eavConfig->getAttribute(Customer::ENTITY, 'sample_attribute');

		// more used_in_forms ['adminhtml_checkout','adminhtml_customer','adminhtml_customer_address','customer_account_edit','customer_address_edit','customer_register_address']
		$sampleAttribute->setData(
			'used_in_forms',
			['adminhtml_customer']

		);
		$sampleAttribute->save();
	}
}

Now, let’s run a command line to install the module: php magento setup:upgrade and php bin/magento setup:static-content:deploy Then check the result. It will show like this:
