How to assign a group to a user based on their email domain in Magento 2.3

[SoulMan77]

I need during registration process to assign a different group to users that has a specific domain e-mail:

So user with: abc@domain.com, 123@domain.com, …@domain.com will be assigned to a specific group all others will be assigned to default group.

I searched a lot, but I found only solutions for Magento 1.

Thank you

Hello @SoulMan77 

Did you ask to amasty guys? In their extension, they have email in their rule which you can use. I think that's for the same purpose you are looking for.

Ask them once and then purchase.

We also have that extension but don't have the functionality you are looking for.

So if you don't get anywhere, you can ask us for the customization.

You can create a before plugin for "CreateAccount()".

I have also somewhat same requirement and in that before creating account i was checking the registered information and assigned the group accordingly.

You can take help from the below code.

class CreateAccount
{
protected $request;

public function __construct(
RequestInterface $request,
Data $helper
) {
$this->request = $request;
$this->helper = $helper;
}

public function beforeCreateAccount(
AccountManagement $subject,
CustomerInterface $customer,
$password = null,
$redirectUrl = ''
) {
$storeOwner = $this->request->getParam('store_owner');
$customerGroupId = $this->helper->getGroupId();
if (isset($storeOwner) && $storeOwner!='') {
$customer->setGroupId($customerGroupId);
}
return [$customer, $password, $redirectUrl];
}
}

In this function you can check the email and accordingly assign the group there.

Thanks

You can do this using the Magento event observer as well.

1. Create events.xml file at the following location.
app\code\Vendor\Extension\etc\events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="customer_register_success">
        <observer name="vendor_extension_customer_register_success" instance="Vendor\Extension\Observer\Customer\RegisterSuccessObserver" />
    </event>
</config>

2. Now create the Observer File RegisterSuccessObserver.php at the following location.
app\code\Vendor\Extension\Observer\Customer\RegisterSuccessObserver.php

<?php
namespace Vendor\Extension\Observer\Customer;

use Magento\Framework\Event\ObserverInterface;

class RegisterSuccessObserver implements ObserverInterface
{
    public function __construct(.......) { }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $customer = $observer->getEvent()->getCustomer();
        // DO YOUR LOGIC HERE 
       // GET CUSTOMER EMAIL and do your logic
    }
}

So you think that my logic could be like this?

        $DiscountGroup=5;
        $GuestGroupId=2;
        list($user, $domain) = explode('@',$customer->getEmail());

        if ($domain == 'mydomain.com'):
            /* set Customer group as DiscountedGroup*/
            $customer->setData('group_id',$DiscountGroup);   
        else:
            $customer->setData('group_id',$GuestGroupId);   
        endif;

Yes, you need to change group based on your conditions and save the customer.

Hi Dhiren,

could you explain how to save user?

I integrated all your script, but doesn't work.

Here my complete RegisterSuccessObserver.php:

<?php
namespace Sieu\Extension\Observer\Customer;

use Magento\Framework\Event\ObserverInterface;

class RegisterSuccessObserver implements ObserverInterface
{
    public function __construct() { }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $customer = $observer->getEvent()->getCustomer();
        $DiscountGroup=4;
        $GuestGroupId=1;
        list($user, $domain) = explode('@',$customer->getEmail());

        if ($domain == 'mydomain.com'):
            /* set Customer group as DiscountedGroup*/
            $customer->setData('group_id',$DiscountGroup);   
        else:
            $customer->setData('group_id',$GuestGroupId);   
        endif;
    }
}
