query update database bermasalah pada codeignitor

Assalamualaikum sudah 2x saya submit pertanyaan 505 terus..... haduh...

ok gini kak pertama2 saya mau tanya kenapa pada codingan aplikasi query update ke tabel database saya ini ga berjalan? padahal statusnya sukses.... berikut codingnya.

Controller:

public function reviewfile($id)
    {
        $data['judul'] = 'Review laporan';
        $data['verifikasi'] = $this->Verifikasi_model->getUploadById($id);
        $data['status'] = ['pending', 'revisi', 'sukses'];

        $this->form_validation->set_rules('status', 'Status', 'required');
        $this->form_validation->set_rules('keterangan', 'Status', 'required');
        if ($this->form_validation->run() == FALSE) {
            $this->load->view('templates/header', $data);
            $this->load->view('verifikasi/reviewfile');
            $this->load->view('templates/footer');
        } else {
            $this->Verifikasi_model->reviewDataVerifikasi();
            $this->session->set_flashdata('flash', 'diupload');
            redirect('verifikasi');
        }
        if ($_POST) {
            $centang = $this->input->post('keterangan');
            $object = implode(",", $centang);
            $this->Verifikasi_model->reviewDataVerifikasi(array('option' => $object));
        }
    }

Model:

public function reviewDataVerifikasi()
    {
        $data = [
            "catatan" => $this->input->post('catatan', true),
            "keterangan" => $this->input->post('keterangan', true),
            "status" => $this->input->post('status', true)
        ];
        $this->db->where('file_id', $this->input->post('id'));
        $this->db->update('banyumas_kober', $data);
    }

detail pertanyaan:

1. Apa yang salah dari codingan tersebut, kenapa saya tanya karena tidak muncul tulisan error sama sekali (malahan tulisannya sukses) akan tetapi data yang saya input tidak masuk ke tabel database saya??

2. Sepertinya permasalahan utama ada di page view pada bagian pengkondisian atribut name 'keterangan', 'status', atau 'catatan' saya bingung??

Mohon bimbingannya para guru... saya sangat apresiasi dengan bantuan kalian
