Как устранить ошибку в методе?

получаю ошибку при сохранении данных.

Дебажил атрибуты метода,все приходят, но $id=0, может из-за него я  получаю  false на проверке.Хотя это не точно, т.к. я не силен в данном фреймворке и если убрать мой добавленный фукнционал,а именно строку: 'marketing_reason_for_leaving_id' => $this->input->post('marketing_reason_for_leaving_id') ? $this->input->post('marketing_reason_for_leaving_id') : null,

то все работает. Как можно исправить?

Может кто поможет исправить...
