Preselect a dropdown with the logged in user_name

In the setup I placed Custom Code in the load Event to get user name who logged in at Joomla with following code

<?php 
$user = JFactory::getUser();
echo $user;
?>

I see on the form when executed that $user is known by testing with the echo command.

In the form I have a dropdown that is filled with data from a database. In the field Option I filled in

{var:read_data4}

. This is the name from the Read Data action in the load event. When executing the form I see al the names coming from the database. So far so good.

I like now to preselect the name from the user that is logged in, and known by $user->name.
There for I'm looking for a few days but can't find the solution for this.

Can anyone help me with this ?

Hi Verreyt,

In v6 you can do this by adding the following code to the "Selected values" box in the dropdown settings:

{user:name}

No php is needed.
