Create the file Test\CustomAttribute\Setup\InstallData.php

<?php namespace test\CustomAttribute\Setup; use Magento\Customer\Setup\CustomerSetupFactory; use Magento\Customer\Model\Customer; use Magento\Eav\Model\Entity\Attribute\Set as AttributeSet; use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory; use Magento\Framework\Setup\InstallDataInterface; use Magento\Framework\Setup\ModuleContextInterface; use Magento\Framework\Setup\ModuleDataSetupInterface; /** * @codeCoverageIgnore */ class InstallData implements InstallDataInterface { /** * @var CustomerSetupFactory */ protected $customerSetupFactory; /** * @var AttributeSetFactory */ private $attributeSetFactory; /** * @param CustomerSetupFactory $customerSetupFactory * @param AttributeSetFactory $attributeSetFactory */ public function __construct( CustomerSetupFactory $customerSetupFactory, AttributeSetFactory $attributeSetFactory ) { $this->customerSetupFactory = $customerSetupFactory; $this->attributeSetFactory = $attributeSetFactory; } public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) { /** @var CustomerSetup $customerSetup */ $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]); $customerEntity = $customerSetup->getEavConfig()->getEntityType('customer'); $attributeSetId = $customerEntity->getDefaultAttributeSetId(); /** @var $attributeSet AttributeSet */ $attributeSet = $this->attributeSetFactory->create(); $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId); $customerSetup->addAttribute(Customer::ENTITY, 'custom_attribute', [ 'type' => 'varchar', 'label' => 'Custom Attribute', 'input' => 'text', 'required' => false, 'visible' => true, 'user_defined' => true, 'position' =>999, 'system' => 0, ]); $attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'custom_attribute') ->addData([ 'attribute_set_id' => $attributeSetId, 'attribute_group_id' => $attributeGroupId, 'used_in_forms' => ['adminhtml_customer'],//you can use other forms also ['adminhtml_customer_address', 'customer_address_edit', 'customer_register_address'] ]); $attribute->save(); } }

Create a custom module and then put the setup file InstallData.php in app\code\YourPackageName\YourModuleName\Setup as shown bellow:

 <?php namespace YourPackageName\YourModuleName\Setup; use Magento\Framework\Module\Setup\Migration; use Magento\Framework\Setup\InstallDataInterface; use Magento\Framework\Setup\ModuleContextInterface; use Magento\Framework\Setup\ModuleDataSetupInterface; class InstallData implements InstallDataInterface { /** * Customer setup factory * * @var \Magento\Customer\Setup\CustomerSetupFactory */ private $customerSetupFactory; /** * Init * * @param \Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory */ public function __construct(\Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory) { $this->customerSetupFactory = $customerSetupFactory; } /** * Installs DB schema for a module * * @param ModuleDataSetupInterface $setup * @param ModuleContextInterface $context * @return void */ public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) { $installer = $setup; $installer->startSetup(); $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]); $entityTypeId = $customerSetup->getEntityTypeId(\Magento\Customer\Model\Customer::ENTITY); $customerSetup->removeAttribute(\Magento\Customer\Model\Customer::ENTITY, "mobile"); $customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, "mobile", array( "type" => "varchar", "backend" => "", "label" => "Mobile No", "input" => "text", "source" => "", "visible" => true, "required" => true, "default" => "", "frontend" => "", "unique" => false, "note" => "" )); $mobile = $customerSetup->getAttribute(\Magento\Customer\Model\Customer::ENTITY, "mobile"); $mobile = $customerSetup->getEavConfig()->getAttribute(\Magento\Customer\Model\Customer::ENTITY, 'mobile'); $used_in_forms[]="adminhtml_customer"; $used_in_forms[]="checkout_register"; $used_in_forms[]="customer_account_create"; $used_in_forms[]="customer_account_edit"; $used_in_forms[]="adminhtml_checkout"; $mobile->setData("used_in_forms", $used_in_forms) ->setData("is_used_for_customer_segment", true) ->setData("is_system", 0) ->setData("is_user_defined", 1) ->setData("is_visible", 1) ->setData("sort_order", 100); $mobile->save(); $installer->endSetup(); } }
