I want to add a custom attribute in customer registration form. I write a module with the following InstallData.php


namespace vendor\TestModule\Setup;

use Magento\Customer\Model\Customer;
use Magento\Customer\Setup\CustomerSetup;
use Magento\Customer\Setup\CustomerSetupFactory;
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;

    public function __construct(CustomerSetupFactory $customerSetupFactory) {
        $this->customerSetupFactory = $customerSetupFactory;

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) {
        /** @var CustomerSetup $customerSetup */
        $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

        $customerSetup->addAttribute(Customer::ENTITY, 'client_idn', [
            'label' => 'Client IDN',
            'input' => 'text',
            'required' => false,
            'sort_order' => 40,
            'visible' => true,
            'system' => false,
            'is_used_in_grid' => true,
            'is_visible_in_grid' => true,
            'is_filterable_in_grid' => true,
            'is_searchable_in_grid' => true]

        // add attribute to form
        /** @var  $attribute */
        $attribute = $customerSetup->getEavConfig()->getAttribute('customer', 'client_idn');
        $attribute->setData('used_in_forms', ['adminhtml_customer', 'customer_account_create']);



In database, the records are successfully inserted. enter image description here enter image description here

However, the custom attribute does not show up in the registration form. enter image description here

Is there anything wrong?


If your install data script successfully installed your custom attribute, now you just need to override addition information phtml file and set your custom attribute in that.

Create Vendor/TestModule/view/layout/customer_account_create.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <referenceContainer name="form.additional.info">
        <block class="Magento\Framework\View\Element\Template" name="additional_info_customer_client_idn" template="Vendor_TestModule::additionalinfocustomer.phtml"/>

Create Vendor/TestModule/view/frontend/templates/additionalinfocustomer.phtml

<fieldset class="fieldset create account" data-hasrequired="<?php /* @escapeNotVerified */ echo __('* Required Fields') ?>">
    <legend class="legend"><span><?php /* @escapeNotVerified */ echo __('Additional Information') ?></span></legend>
    <div class="field regulation">
        <label for="regulation" class="label"><span><?php /* @escapeNotVerified */
                echo __('Client IDN') ?></span></label>
        <div class="control">
            <input type="text" name="client_idn" id="client_idn" title="<?php /* @escapeNotVerified */ echo __('Client IDN') ?>" class="input-text" data-validate="{required:false}">

Clear cache and review frontend customer account registration page.

    Vendor/TestModule/view/layout/customer_account_create.xml should be Vendor/TestModule/view/frontend/layout/customer_account_create.xml – William Oakley Oct 18 '16 at 11:28

@Jonak's answer "the most voted" is correct, however you need to create the layout folder inside frontend folder just like that:






It should be added in front-end or html level.

Assume you are using Luma theme

Go to customer registration form root/vendor/magento/module-customer/view/frontend/templates/form/register.phtml add below code

<div class="field required">
    <label for="client_idn" class="label"><span><?php /* @escapeNotVerified */ echo __('Client Idn') ?></span></label>
    <div class="control">
        <input type="client_idn" name="client_idn" id="client_idn" value="<?php echo $block->escapeHtml($block->getFormData()->getClientIdn()) ?>" title="<?php /* @escapeNotVerified */ echo __('client_idn') ?>" class="input-text" data-validate="{required:true}">

Remove the cache and check the visibility in front end.

Check whether the value is passing to customer registration controller or not.

@Aaron Allen said in comment override the file by module. editing code in core files is not recommended.

Hope this helps.

  • Override the file with your module instead. Editing a core file is bad. – Aaron Allen Jul 30 '16 at 19:29
  • @ Aaron Allen Thanks, i forgot to mention, modified the answer. – Krishna ijjada Jul 30 '16 at 20:33
  • @krishnaijjada, but why this? <?php echo $block->escapeHtml($block->getFormData()->getEmail()) ?> – Paul Jul 31 '16 at 7:38
  • it renders data from session if it is already set. $formData = $this->_customerSession->getCustomerFormData(true); – Krishna ijjada Jul 31 '16 at 8:01
  • but data is not saving from frontend – Sarvesh Tiwari Feb 21 '17 at 10:16

you can checkout an excellent tutorial link for creating custom attribute for Customer. This also contains video.
Follow the steps. It works.
Hope this helps.


It happen because your entity in

$customerSetup->getEavConfig()->getAttribute('customer', 'client_idn');



But saving form data exist only in


(have a look at function _afterSave)

This is not best practice, but solution:

        $attribute = $this->attributeFactory->create();
        $attribute->loadByCode($attributeArray['type'], $attributeArray['code']);
        $attribute->setData('used_in_forms', $attributeForms);

where AttributeFactory is: Magento\Customer\Model\AttributeFactory; attribute forms are:

    $attributeForms = [

attribute array:

        'type' => 'customer_address',
        'code' => 'title',
