php – CodeIgniter批量插入特定列

Table shortlisted_candidates
id int PRIMARY KEY AUTO INCREMENT,candidate_no int NOT NULL,written_marks int,viva_marks int

我想在这个表中执行insert_batch,但是数据只会插入id和candidate_no列中.

我知道Codeigniter Active Records Class为批量插入提供了$this-> db-> insert_batch()函数,但它实际上是在整个表中插入数据,而我希望数据只插入到特定的列中.我怎样才能在CodeIgniter中实现这一目标？

请注意,id是AUTO INCREMENT,PRIMARY KEY列.

我的控制器代码：

class Shortlisted_candidates extends MY_Controller
{

    function __construct()
    {
        parent::__construct();
        $this->load->database();
        $this->load->model('Shortlisted_candidate');
        $this->load->helper('url');
        $this->load->helper('html');
        $this->load->helper('form');
        $this->output->enable_profiler(false);
    }
    function add(){
        $data = array();
        if ($_POST) {

            $data['candidate_no'] = $this->input->post('candidate_no');
            $this->Shortlisted_candidate->add_candidate_to_shortlist($data);
            $this->session->set_flashdata('message','Data Successfully Added');
            redirect('shortlisted_candidates/add');
        }
    }
}

我的型号代码：

class Shortlisted_candidate extends CI_Model
{

    function __construct()
    {
        // Call the Model constructor
        parent::__construct();
    }

    function add_candidate_to_shortlist($data){
        //Following code inserts data in ALL COLUMNS
        $this->db->insert_batch('shortlisted_candidates',$data);
        //How to write active record batch insert query for inserting data in only `id` and `candidate_no` column?
    }
}
