Question

我使用codeigniter3.0.0版本，当我运行项目时，我收到此错误，请告诉我如何修复此错误。

错误号码：1048

列'no_of_people'不能为空

INSERT INTO reservation（no_of_people）VALUES（NULL）

文件名：C：/xampp/htdocs/book/application/models/Books_model.php

行号：26

我的型号代码是

class Books_model extends CI_Model{



public function __construct(){

    $this->load->database();


}

public function get_restaurants()
{
    $sql = "SELECT restaurant_id, names FROM restaurants ";
    $query = $this->db->query( $sql );
    return $query->result();

}

public function insert_into_db()
{
   $people =$this->input->post('no_of_people');
   return $this->db->insert('reservation', array('no_of_people'=>$people));

}

}

控制器

<?php error_reporting(E_ALL); ini_set('display_errors', 1);

类Booking_Controller扩展了CI_Controller {

    public function __construct(){


        parent::__construct();
        $this->load->model('Books_model');

    }


public function view()
{





    $data['result']=$this->Books_model->get_restaurants();

    $this->load->helper(array('form','url'));
    $this->load->view('restaurants/booking',$data);

    $this->Books_model->insert_into_db();

}

}

查看代码

 <form action="<?php echo base_url();?>booking_controller/view" method="POST">

                    <table>
                        <tr>
                            <td>number of people</td>
                    <td>number of people = <input type = 'text' name='no_of_people'></td>
                        </tr>
                    <tr>
                        <td><input type='submit' value="Submit"></td>

                    </tr>
                </table>
                </form>

当我在no_of_people列上应用空约束时，仅在数据库中应用空值存储 Plz指导我错误的地方...... thanx
