Я новичок в CodeIgniter и нуждаюсь в некоторой помощи :). Мне удалось создать функции CRUD с помощью ajax над некоторыми учебниками, и я могу редактировать, добавлять новые, удалять всех пользователей, указанных на моей странице. То, что я хочу сейчас, это когда я вхожу в систему с пользователем, я просто хочу, чтобы зарегистрированный профиль был отредактирован, а не другие. Пожалуйста, если кто-то может мне помочь, как я могу это сделать. Заранее спасибо.Редактировать профиль пользователя Ajax

Простое наблюдение, но в верхней части вашей модели и контроллера вы неправильно произвели «скрипт». – Brad
