I have a custom phtml file that contains a copy of the customer registration form in my Magento 2.1 site. Now in this form I have

<input type="hidden" name="group_id" id="group_id" value="3" />

I also created a file located in app/code/Magento/Customer/Model called CustomerExtractor.php and the contents of the file is below but now when I creat a test customer using the new registration for the user is not assigned to the group_id that is set in the form?

  • Hey, is issue fixed? – Konrad Siamro Oct 12 '17 at 13:07
  • No I am still not able to figure out how to get this issue resolved. I even set a bounty to try to get more people into this thread but that did not work. – Jayreis Oct 12 '17 at 14:31
  • @user1739740 Do you want to have all registered customers in customer_group_id=3? if so, this can be easily accomplished by an observer.' – Yogesh Agarwal Oct 13 '17 at 8:03

This is not the only issue in Magento Custom registration form , also the issue exists in Default registration form.If we passing any group_id from default registration form then that customer group does not set for that customer it always takes store default group_id For in case of default registration form Issue in [Magento\Customer\Model\CustomerExtractor] c(https://github.com/magento/magento2/blob/develop/app/code/Magento/Customer/Model/CustomerExtractor.php#L92) class. Even , i enabled attribute group_id in customer registration form using

INSERT INTOcustomer_form_attribute(form_code,attribute_id) VALUES ('customer_account_creat', '10');

But still is does not work bcoz...

Logic issue in if ($isGroupIdEmpty) {

Means, instead of enabling group_id for customer registration form and sending this field value from , Magento forcefully set Customer group as the default group .

That is the problem.


Solution is that, we need to modify condition

  1. don't execute $customerDataObject->setGroupId( when _group_id_ is enable for registration form

  2. execute $customerDataObject->setGroupId( when _group_id_ is not enable for registration form

  3. execute $customerDataObject->setGroupId( when _group_id_ is enable for registration form * but group id **does not selected from form

So. my suggestion change if ($isGroupIdEmpty) {


if (!$isGroupIdAllow || ($isGroupIdAllow &&(is_null($customerDataObject->getGroupId()))) ) { $customerDataObject->setGroupId( $this->customerGroupManagement->getDefaultGroup($store->getId())->getId() ); }

Also for use developer perspective change variable name $isGroupIdEmpty



  • thanks for the comments. So in which file and what path to the file and I changing the if ($isGroupIdEmpty) { line in? – Jayreis Sep 28 '17 at 17:57
  • So I created a the directrory /Magento/Customer/Model in the app/code directory. Now I created the file CustomerExtractor.php and put the contents in there from the github. and changed by !$isGroupIdAllow section but when I create a customer from my custom for where I have a hidden field setting the group_id it still does not work the customer is created by assigned to the default group ? – Jayreis Sep 28 '17 at 19:05
  • I am still looking for guidance on this. – Jayreis Oct 5 '17 at 20:44

Im not sure exactly that you need.
This solution will add customer group select to registration form.
1. In template form/register.phtml in fieldset add :

    <div class="field customer-groups required">
        <label for="customer-group" class="label"><span><?php echo __('Customer Group') ?></span></label>
        <select name="customer_group" id="customer-group" data-validate="{required:true}">
            <option value=""><?php echo __('Customer Group') ?></option>
            <?php foreach ($block->getCustomerGroups() as $customerGroup) : ?>
                    value="<?php echo $customerGroup->getId(); ?>"
                    <?php echo ($customerGroup->getId()==$block->getFormData()->getCustomerGroup())? 'selected' : ""; ?>><?php echo $customerGroup->getCode(); ?></option>
            <?php endforeach ?>

In block add function getCustomerGroups :

public function __construct(
    \Magento\Framework\View\Element\Template\Context $context,
    \Magento\Directory\Helper\Data $directoryHelper,
    \Magento\Framework\Json\EncoderInterface $jsonEncoder,
    \Magento\Framework\App\Cache\Type\Config $configCacheType,
    \Magento\Directory\Model\ResourceModel\Region\CollectionFactory $regionCollectionFactory,
    \Magento\Directory\Model\ResourceModel\Country\CollectionFactory $countryCollectionFactory,
    \Magento\Framework\Module\Manager $moduleManager,
    \Magento\Customer\Model\Session $customerSession,
    \Magento\Customer\Model\Url $customerUrl,
    \Magento\Customer\Model\ResourceModel\Group\Collection $customerGroupCollection,
    $data = []
    $this->customerGroupCollection = $customerGroupCollection;
    parent::__construct($context, $directoryHelper, $jsonEncoder, $configCacheType, $regionCollectionFactory,
        $countryCollectionFactory, $moduleManager, $customerSession, $customerUrl, $data);

 * @return array
public function getCustomerGroups()
    $result = [];
    $array = $this->customerGroupCollection->toOptionArray();
    foreach ($array as $item) {
        if($item['value'] == 0) {
        $result[] = $this->createGroupObject($item);

    return $result;

 * @param array $item
 * @return \Magento\Framework\DataObject
private function createGroupObject(array $item)
    $object = new \Magento\Framework\DataObject();
    $object->setData('id', $item['value']);
    $object->setData('code', $item['label']);

    return $object;
  • Konrad what is the file path and name of file I would add the "In block function getCustomerGroups ?? – Jayreis Oct 13 '17 at 13:22
  • Konrad what is the file path and name of file I would add the "In block function getCustomerGroups ?? If I add the code to the CustomerData.php file located in /vendor/magento/module-customer/Block I get a 500 error – Jayreis Oct 13 '17 at 13:31
  • It should be done in block used by template form/register.phtml. The best way - create new module and rewrite form/register.phtml and block Magento\Customer\Block\Form\Register - here you should add function getCustomerGroups. – Konrad Siamro Oct 18 '17 at 10:33
