How to display the username in a template

Question

How can I display the logged in user name in a template?

Example:

$this->output('<div>Welcome USERNAME you are logged in!</div>');

Answer 1

Search all the code for "handle" instead of "username" and you find your desired functions. E.g.:

$username = qa_get_logged_in_handle();

if(isset($username)) {

   $this->output('<div>Welcome '.$username.' you are logged in!</div>');

}
