Select Option in foreach only get value in last select option (Code Igniter)

Question

Why I can't post a select option value in foreach loop? It just save the last select option value.

It's only save the "Rutinitas" value in Printer (which is the last select option), but doesn't save the CPU or Mouse "Rutinitas" option value.

This is the controller

public function tampilkanKomponen2($tgl_cek,$nama_alat) {
    if($this->session->userdata('logged_operator')) {
         $session_data = $this->session->userdata('logged_operator');
         $nip = $session_data['nip'];
         $nama = $session_data['username'];
        $hasil = $this->operator_model->getByAlat($nama_alat)->result();
        $hasil2 = $this->operator_model->showPengecekan()->result();    
        $data =array (
            'nip' => $nip,
            'nama' => $nama,
            'hasil2' => $hasil2,
            'hasil' => $hasil,
            //'hasil2' => $hasil2,
            'tgl_cek' => $tgl_cek,
            'nama_alat' => $nama_alat
            //'id_komponen2' =>$id_komponen
        );
        $this->load->view('tambah_pengecekan3_v',$data);
    }
    else {
        echo "<script> history.go(-1); </script>";
    }
}

public function simpanPengecekan() {
    if($this->operator_model->check_logged()==TRUE) {
        $session_data = $this->session->userdata('logged_operator');
        $nip = $session_data['nip'];
        $id_komponen = $this->input->post('id_komponen');
        $tgl_cek = $this->input->post('tgl_cek');
        $rutinitas = $this->input->post('rutinitas');
        $kriteria = $this->input->post('kriteria');
        $tindakan = $this->input->post('tindakan');
        $nama_alat = $this->input->post('nama_alat');

        $data =array (
            'id_komponen' => $id_komponen,
            'tgl_cek' => $tgl_cek,
            'rutinitas' => $rutinitas,
            'kriteria' => $kriteria,
            'tindakan' => $tindakan,
            'operator' => $nip
        );
        $hasil = $this->operator_model->tambahPengecekan($data);
        //redirect(base_url('operator'));
        $this->tampilkanKomponen2($tgl_cek,$nama_alat);
        //redirect_back();
    }
    else {
        echo "<script> history.go(-1); </script>";
    }
}

This is the view

Answer 1

Change select name to rutinitas[]

<select name="rutinitas[]" class="form-control">
          <option value="Harian"> Harian </option>
          <option value="Mingguan"> Mingguan </option>
          <option value="Bulanan"> Bulanan </option>
          <option value="3 Bulanan"> 3 Bulanan </option>
          <option value="6 Bulanan"> 6 Bulanan </option>
          <option value="Tahunan"> Tahunan </option>
      </select>

if you want to insert all selected value in same column of table then use implode

  $rutinitas = implode(',',$this->input->post('rutinitas'));
