Обратите внимание, что PHP скрипт и HTML-форм все в один файл.

Answer 1

Изменить имя переменного в training_index.php

$conn and $connection to $conn 

Поскольку в connection.php файла, который вы упомянули вашу БД соединения имя переменного, как

$con = new mysqli($servername, $username, $password, $dbname);
