Are you finding how to create customer attribute in Magento 2 programmatically? The article is your answer. Follow our guide below, we use a simple module demo coding for this lesson, so for the first, you need to read the tutorial here to create a simple module as BSS_HelloWorld. And now are the instructions to add customer attribute Magento 2 in 2 ways: using code and Magento extensions.

Step-by-Step to Create Customer Attribute in Magento 2 Programmatically

Step 1: Create a setup file InstallData.php

Firstly, we need to create the InstallData.php file located at file: app/code/BSS/HelloWorld/Setup/InstallData.php.

<?php
namespace BSS\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;
       }
}

Step 2: Define the install() Method

After this step, we define the install() method and create eav setup model by using the code below:

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

And now, we use this eav setup model to create customer attribute in Magento 2:

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 set the forms for the attributes that will be used. For that, we need to define the eavConfig object that will allow us to call the attribute back and set the data.

<?php
namespace BSS\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 us run this command line to install the module:

php magento setup:upgrade and php bin/magento 
setup:static-content:deploy

Why Need to Create Customer Attribute in Magento 2?

Magento 2, with its default settings, offers a good foundation for understanding your customers. However, creating custom customer attributes unlocks a new level of personalization and insight, bringing several significant benefits, including:

Gather specific customer data: The default attributes might not capture everything you need to know about your customers. Custom attributes let you collect information tailored to your business, like loyalty program membership numbers, preferred communication methods (email/SMS), or even birthdays for targeted promotions.

Enhanced customer segmentation: With richer customer data, you can segment your audience more effectively. This allows for targeted marketing campaigns, personalized product recommendations, and loyalty programs that truly resonate with different customer groups.

Improved customer experience: By understanding your customers better, you can personalize their shopping journey. Imagine recommending relevant products based on past purchases or offering loyalty points for specific actions. This creates a more engaging and rewarding experience for your customers.

Deeper customer insights: Custom attributes provide valuable data for analyzing customer behavior and preferences. You can identify trends, understand purchase motivations, and optimize your store based on real customer data, leading to better decision-making.

Streamlined checkout process: While custom attributes are powerful, it’s important to use them strategically. Magento 2’s dependent attribute feature allows you to only display relevant fields based on customer selections, preventing lengthy forms that can lead to cart abandonment.
