How to make hyperlink from author name in Wordpress? - php

Question

I'm a total newbie to Wordpress and having a hard time figuring things out.
I'm using plugin called "WP-Pro-Quiz", a quiz plugin, and within the plugin there's an option to show "Leaderboard" of all users who completed the quiz. In the leaderboard on the frontend, there's user id, time, points and user's Display Name, etc for each user..
What I want to achieve is to make Display name clickable (and then to go to author's profile once clicked). That is, to connect Display Name with author profile who took the quiz, to create hyperlink from Display Name.
This is from controller WpProQuiz_Controller_Toplist.php :
<?php
class WpProQuiz_Controller_Toplist extends WpProQuiz_Controller_Controller
{
public function route()
{
$quizId = $_GET['id'];
$action = isset($_GET['action']) ? $_GET['action'] : 'show';
switch ($action) {
default:
$this->showAdminToplist($quizId);
break;
}
}
private function showAdminToplist($quizId)
{
if (!current_user_can('wpProQuiz_toplist_edit')) {
wp_die(__('You do not have sufficient permissions to access this page.'));
}
$view = new WpProQuiz_View_AdminToplist();
$quizMapper = new WpProQuiz_Model_QuizMapper();
$quiz = $quizMapper->fetch($quizId);
$view->quiz = $quiz;
$view->show();
}
