У меня есть эта форма, которая позволяет мне добавлять пользователей в мою базу данных.Поля базы данных по умолчанию для определенного значения
Когда я добавить новую запись и введите каждое поле с данными и представить, он успешно добавляет данные в базу данных
Однако при попытке обновить конкретную запись и нажмите отправить мою MemberID поле автоматически устанавливается значение и я не уверен, откуда это может быть (см. здесь http://imgur.com/MK07epA)
Я просмотрел весь свой код и не могу найти, что его вызывает.
При попытке обновить или удалить записи после первого обновления, я получаю следующие сообщения об ошибках: (http://imgur.com/Qs0IQKi)

Ну, вы делаете это сами, смотрите здесь опечатка: '$ запрос =«Члены обновления установите MemberID = „#memberID“, ' –
