Hi,
Thanks for your reply. Yes, I realized then, was already very late in the evening.
Maybe you could implement in some release this function as {user id displayed}:
I solved this with:
require_once (JPATH_SITE . '/components/com_jsn/helpers/helper.php');
$username = '{user username displayed}';
$userId = JUserHelper::getUserId($username);
I need this to create a profile url in the table list. Because only the "Formatname, Username etc. is linked to the profile in the table list. But with this Joomla Core Function it works, but I had to use php..
