обновления и удаление таблицы данных с PHP

Моей проблема: Когда я нажимаю кнопку Удалить или обновить их удалить информацию о текстовых полях, и не делать ничего другого, они не показывают какой-либо error.I я новичок в программировании, если кто-то может мне помочь, я был бы благодарен.

P.S: Извините за мой плохой английский.

Смешивание MySQLi с MySQL !!! – Saty

Вы никогда не проверяете наличие ошибок, поэтому вы не видите ни одного – Jens

вашего выполнения одного и того же запроса несколько раз. – JYoThI

Вы перепутали все, как mysql, mysqli, Несколько соединений. Пожалуйста, используйте mysql или mysqli для всего скрипта. Нет необходимости выбирать db столько времени.

Ваш код нуждается в некоторой модификации, например $ retval = mysqli_query ($ sql, $ conn); Неверно $ retval = mysqli_query ($ conn, $ sql); Право
