How to Create Customer Attribute in Magento 2

In Magento 2 Customer Attributes are used for adding extra attribute fields to collect valuable customer information on registration or account page. MageAnts have developed via module Magento 2 Customer Attributes so you don't need any programming with our programming.

Magento 2 create/add customer attribute

Step 1

: Firstly, we will create the InstallData.php file at below path :

Mageants > Blog > Setup > InstallData.php

<?php

namespace Mageants\Blog\Setup;

use Magento\Eav\Model\Config;

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,

  Config $eavConfig

 ) {

  $this->eavSetupFactory = $eavSetupFactory;

  $this->eavConfig = $eavConfig;

 }

 public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)

 {

  $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

  $eavSetup->addAttribute(

   \Magento\Catalog\Model\Customer::ENTITY,

   'my_custom_attribute',

   [

    'label' => 'My Custom Atrribute',

    'system' => 0,

    'position' => 700,

    'sort_order' => 700,

    'visible' => true,

    'note' => '',

    'type' => 'varchar',

    'input' => 'text',

   ]);

   $this->getEavConfig()->getAttribute('customer', 'my_custom_attribute')->setData('is_user_defined', 1)->setData('is_required', 0)->setData('default_value', '')->setData('used_in_forms', ['adminhtml_customer', 'checkout_register', 'customer_account_create', 'customer_account_edit', 'adminhtml_checkout'])->save();

 }

 public function getEavConfig() {

  return $this->eavConfig;

 }

}

 

Step 2

: After Creating InstallData.php You have to run php magento setup:upgrade and php bin/magento setup:static-content:deploy Then check the result at admin side customer details page as below :

 

Magento 2 set customer custom attribute value

To set Custom Customer Attribute value you have to use below block of code in your controller file : Here, we have used Magento\Customer\Model\Customer instance and created it’s object($customer) and used Magento\Customer\Model\ResourceModel\CustomerFactory instance and created it’s object($customerFactory).

<?php

namespace Mageants\Blog\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action

{

 public function __construct(

  \Magento\Customer\Model\Customer $customer,

  \Magento\Customer\Model\ResourceModel\CustomerFactory $customerFactory,

  \Magento\Framework\App\Action\Context $context

 ) {

  $this->customer = $customer;

  $this->customerFactory = $customerFactory;

  return parent::__construct($context);

 }

 public function execute()

 {

  $customerId = "1"; // set any cusromer id

  $customer = $this->customer->load($customerId);

  $data = "new customer value"; // set any value

  $customerData = $customer->getDataModel();

  $customerData->setCustomAttribute('my_custom_attribute',$data);

  $customer->updateData($customerData);

  $customerResource = $this->customerFactory->create();

  $customerResource->saveAttribute($customer, 'my_custom_attribute');

 }

}

Magento 2 get customer custom attribute value

To set Custom Customer Attribute value you have to use below block of code in your controller file : Here, we have used Magento\Customer\Api\CustomerRepositoryInterface instance and created it’s object($customerRepositoryInterface).

<?php

namespace Mageants\Blog\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action

{

 public function __construct(

  \Magento\Customer\Api\CustomerRepositoryInterface $customerRepositoryInterface,

  \Magento\Framework\App\Action\Context $context

 ) {

  $this->customerRepositoryInterface = $customerRepositoryInterface;

  return parent::__construct($context);

 }

 public function execute()

 {

  $customer =$this->customerRepositoryInterface->getById(1); // Pass any Customer Id whose custom customer atribute value you want to fetch

  print_r($customer->getCustomAttribute('my_custom_attribute')->getValue());

 }

}
