Обновить запрос, записывающий нулевые значения в базу данных

77
6

Я пытаюсь обновить некоторые поля формы, которые не заполнены, но когда я нажимаю кнопку обновления, более ранние сохраненные значения устанавливаются в 0, а новые вставленные значения остаются неизменными. Это продолжается, если я попытаюсь отредактировать запись снова. ранее сохраненные значения становятся равными 0. Если кто-то мог бы взглянуть на это и помочь мне, было бы здорово

Вот код для страницы редактирования.

Это может быть вызвано использованием disabled = true.

<INPUT TYPE=text name='schulungen_id1' value=$x7 disabled = true>

Из qaru.site/questions/523408/... -

Так работает атрибут disabled. Когда элемент управления формы отключен, значение будет проигнорировано при отправке формы, и ключ не будет присутствовать в $ _POST (или $ _GET).

Если вы хотите, чтобы значение присутствовало в представленных данных, но вы не хотите, чтобы пользователь мог изменять значение на странице (что, я думаю, это то, что вы пытаетесь добиться), используйте readonly = "readonly" вместо disabled = "disabled".
