In this blog, we are going to talk about how to get a current customer group id in Magento 2.

The current customer group ID has several developer requirements. If a customer is logged in then how to know which group he belongs to we have created this blog.

see this code:

public function __construct(
  \Magento\Customer\Model\Session $customer,
  \Magento\Framework\App\Http\Context $_httpContext
)
{
   $this->customer = $customer;
   $this->httpContext = $_httpContext;
}

public function  getCurrentCustomerGroupId() {

$isLoggedIn = $this->  ->getValue(\Magento\Customer\Model\Context::CONTEXT_AUTH);

        if ($isLogin) {
             $currentGroupId = $this->customer->getCustomer()->getGroupId(); 
        } else {
            $currentGroupId = 0;
        }
return $currentGroupId;
}

⇒ Call phtml file:

$_customerGroupsCollection = $block-> getCurrentCustomerGroupId();
 $_customerGroupsCollection->getData();

⇒ Using Object Manager :

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$_customerSession = $objectManager->create('Magento\Customer\Model\Session');

if ($_customerSession ->isLoggedIn()) {

//Get current group ID:-

     $_customerGroupId = $_customerSession->getCustomer()->getGroupId();
     $_groupCollection = $objectManager->create('\Magento\Customer\Model\Group')->load($_customerGroupId);
				
   $_groupCollection->getData();
}
