Magento 2 Custom User Attributes – Add Personalized Fields to Registration

🧩 Magento 2 Custom User Attributes – Add Personalized Fields to Registration

Want to capture more than just name and email? Magento 2 lets you add custom user attributes (like Date of Birth, Gender, Company ID) to customer registration or account pages with ease.

🎯 Where Are User Attributes Stored?

Customer attributes are part of the EAV (Entity-Attribute-Value) model in Magento. You can create your own attributes using setup scripts or declarative schema.

🛠 Create a Custom Customer Attribute

Here’s how to add a custom customer attribute called company_id.

// Add a custom attribute to the customer entity
$customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
$customerSetup->addAttribute(
    \Magento\Customer\Model\Customer::ENTITY,
    'company_id',
    [
        'type' => 'varchar',
        'label' => 'Company ID',
        'input' => 'text',
        'required' => false,
        'visible' => true,
        'user_defined' => true,
        'position' => 200,
        'system' => 0,
    ]
);

// Add attribute to forms
$attribute = $customerSetup->getEavConfig()->getAttribute('customer', 'company_id');
$attribute->setData('used_in_forms', ['adminhtml_customer', 'customer_account_create', 'customer_account_edit']);
$attribute->save();

🧪 Display Custom Attribute on Frontend

To show your new attribute on the registration or account edit page, ensure it’s added in:

view/frontend/templates/form/register.phtml

Example:

<div class="field">
    <label for="company_id">Company ID</label>
    <input type="text" name="company_id" id="company_id" />
</div>

🔄 Save & Load Attribute Data

Magento will automatically save and load the value once it’s registered in the forms. You can also retrieve it programmatically:

// Get the custom attribute value
$customer = $this->customerRepository->getById(123);
$companyId = $customer->getCustomAttribute('company_id')->getValue();
