How to get the current user? External App

majoh · February 23, 2021, 9:02am

Hi there,

some time ago we wrote a little helping app, which worked fine.

After upgrading from NC 18 > 19, we got an issue with the current logged in user.

Working solution:

including the base.php (require_once(’…/lib/base.php’);).
getting the current user with admin privileges ($getusername = OCP\User::getUser();).
checked the user/group db and allowed the access.

Problem now:

including the base.php now crashes the app (unlimited loading)

Question:

What’s the easiest way to simple get the current user name (display name) in PHP?

Sry for the (simple) question, but we stuck at the moment.

Thx, with best regards

Maybe
<?php echo get_current_user(); ?>

Thx for the reply.
This is the server/php user.
We need the current nextcloud user, which we formaly got with: OCP\User::getUser();.

You can use the userSession from dependency Injection.
This gives you an Instance of IUser, of which you can use getDisplayName()
$userSession->getUser()->getDisplayName()

See e.g.

		$this->questionMapper = $questionMapper;
		$this->optionMapper = $optionMapper;
		$this->logger = $logger;
		$this->l10n = $l10n;
		$this->formsService = $formsService;
		$this->secureRandom = $secureRandom;
		$this->dateTimeFormatter = $dateTimeFormatter;
		$this->config = $config;
		$this->currentUser = $userSession->getUser();
	}
	/**

	 * Read Form-List only with necessary information for Listing.

	 */
	public function getForms(): DataResponse {
		$forms = $this->formMapper->findAllByOwnerId($this->currentUser->getUID());
