Magento2 How to get customer group name by using group id?

Question

How can I get customer group name by using group id in a template (phtml file) ?

Answer 1

If you have group id then add below code at your block class

protected $groupRepository;
public function __construct(
    ...
    \Magento\Customer\Api\GroupRepositoryInterface $groupRepository,
    ...
) {
    $this->groupRepository = $groupRepository;
}

public function getGroupName($groupId){
    $group = $this->groupRepository->getById($groupId);
    echo $group->getCode();
}

At last in phtml file you will get group name by:

$block->getGroupName($groupId)

If you want to get group name by group id at phtml using Object manager and donot want edit block class then you can use below code at phtml

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$groupRepository  = $objectManager->create('\Magento\Customer\Api\GroupRepositoryInterface');
$group = $groupRepository->getById([GroupId]);
var_dump($group->getData());
echo $group->getCode();

But direct use of Object manager is not good idea,So best idea to add code at block class.

Answer 2

Update your block:

/**
 * @var \Magento\Customer\Api\GroupRepositoryInterface
 */
protected $groupRepository;

/**
 * @param \Magento\Framework\View\Element\Template\Context $context
 * @param \Magento\Customer\Api\GroupRepositoryInterface $groupRepository
 * @param array $data
 */
public function __construct(
    \Magento\Framework\View\Element\Template\Context $context,
    \Magento\Customer\Api\GroupRepositoryInterface $groupRepository,
    array $data = []
) {
    parent::__construct($context, $data);
    $this->groupRepository = $groupRepository;
}

/**
 * @param $id
 * @return string
 */
public function getGroupNameById($id)
{
    $groupEntity = $this->groupRepository->getById($id);

    return $groupEntity->getCode();
}

use next code in the template:

<?php echo $block->getGroupNameById(1)?>

where the 1 is desired group id.

Answer 3

You should not make such requests in template files. Use blocks for it.

Add \Magento\Customer\Api\GroupRepositoryInterface $groupRepository to the block.

And get group object like

/**
 * Customer group repository
 *
 * @var \Magento\Customer\Api\GroupRepositoryInterface
 */
protected $groupRepository;

public function __construct(
    // …
    \Magento\Customer\Api\GroupRepositoryInterface $groupRepository,
    // …
) {
    // …
    $this->groupRepository = $groupRepository;
    // …
}

public function getGroupCode($groupId) 
{
    $group = $this->groupRepository->getById($groupId);
    return $group->getCode();
}
