如何使用codeigniter编辑两个标签

我想询问我的程序。我想编辑，但无法在jurnal表中编辑，而在bahan_baku表中成功编辑。请救救我。我有两张桌子。

bahan_baku表id_bahanbakuketerangan_bbtanggal_bbjumlah_bbharga_bb

表陪审员id_jurnalid_coa唐格尔debetkredit

这是我的型号->m_bahanbaku.php

function m_edit($data_bb){
    $this->db->where($data_bb);
    $edit_bb = $this->db->get('bahan_baku');
return $edit_bb->result();
    $this->db->where($data_jurnal);
    $edit_jurnal = $this->db->get('jurnal');
return $edit_jurnal->result();
}
function m_update($data_bb, $id_bahanbaku,$data_jurnal, $id_coa){
    $this->db->where('id_bahanbaku', $id_bahanbaku); //untuk tabel bahan_baku
    $this->db->update('bahan_baku', $data_bb);
    $this->db->where('id_jurnal', $id_jurnal); //dari tabel jurnal
    $this->db->update('jurnal', $data_jurnal);

}}

这是我的控制器->bahanbaku.php

 function edit($id_bahanbaku){
    $data_bb=array(
        'id_bahanbaku'=>$id_bahanbaku
        );
    $data_jurnal=array(
        'id_jurnal'=>$id_bahanbaku
        );  
    $data_bb['data_edit']=$this->m_bahanbaku->m_edit($data_bb, $data_jurnal);
    $this->load->view('keuangan/v_edit_bb',$data_bb, $data_jurnal);
 }
 function update(){
    $id_bahanbaku = $this->input->post('id_bahanbaku');
        $data_bb=array(
        'keterangan_bb' => $this->input->post('keterangan_bb'),
        'tanggal_bb' => $this->input->post('tanggal_bb'),
        'jumlah_bb' => $this->input->post('jumlah_bb'),
        'harga_bb' => $this->input->post('harga_bb')
        );
    $id_jurnal = $this->input->post('id_jurnal');
         $data_jurnal=array(
         'tanggal' => $this->input->post('tanggal_bb'),
         'debet'=>$this->input->post('harga_bb'),
         'kredit'=>$this->input->post('harga_bb')
         );
        $this->m_bahanbaku->m_update($data_bb, $id_bahanbaku, $data_jurnal, $id_jurnal);
        redirect(base_url().'keuangan/bahanbaku/lihat');
 }
}

> $this->db->where('id_jurnal', $id_jurnal);

function m_update($data_bb, $id_bahanbaku,$data_jurnal, `$id_coa`)

function m_update($data_bb, $id_bahanbaku,$data_jurnal, $id_coa){
    $this->db->where('id_bahanbaku', $id_bahanbaku); //untuk tabel bahan_baku
    $this->db->update('bahan_baku', $data_bb);
    $this->db->where('id_jurnal', $id_coa); //dari tabel jurnal
    $this->db->update('jurnal', $data_jurnal);
   }
