Вопрос:
У меня действительно странная проблема с моей страницей редактирования:
Если у меня более одной продажи:
Если у меня есть одна продажа и я загружаю новое изображение -> это сохраняет имя файла и имя большого пальца, но изображения на сервере нет.
Если я не загружаю изображение -> оно перезаписывает содержимое всех других продаж с последней отредактированной продажей, но сохраняет правильные изображения.
Если я загружаю изображение, оно удаляет оба изображения и все еще перезаписывает содержимое последней отредактированной продажи
Я пробовал это на локальном сервере MAMP и сервере cPanel

Ответ №1:
Вам нужен второй вызов $this->db->where('id', $id) перед вашим $this->db->update('sales', $content) вызовом в function updateSale() , первый используется в $this->db->get('sales') запросе, но вам нужно сделать это снова для вашего обновления.
Используйте $this->db->where('id', $id)->update('sales', $content)
