在模型目录下创建 Person_model.php
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Person_model extends CI_Model {
var $table = 'persons';
var $column = array('firstname','lastname','gender','address','dob');
var $order = array('id' => 'desc');
public function __construct()
{
parent::__construct();
$this->load->database();
}
private function _get_datatables_query()
{
$this->db->from($this->table);
$i = 0;
foreach ($this->column as $item)
{
if($_POST['search']['value'])
($i===0) ? $this->db->like($item, $_POST['search']['value']) : $this->db->or_like($item, $_POST['search']['value']);
$column[$i] = $item;
$i++;
}
if(isset($_POST['order']))
{
$this->db->order_by($column[$_POST['order']['0']['column']], $_POST['order']['0']['dir']);
}
else if(isset($this->order))
{
$order = $this->order;
$this->db->order_by(key($order), $order[key($order)]);
}
}
function get_datatables()
{
$this->_get_datatables_query();
if($_POST['length'] != -1)
$this->db->limit($_POST['length'], $_POST['start']);
$query = $this->db->get();
return $query->result();
}
function count_filtered()
{
$this->_get_datatables_query();
$query = $this->db->get();
return $query->num_rows();
}
public function count_all()
{
$this->db->from($this->table);
return $this->db->count_all_results();
}
创建控制器文件 Person.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Person extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('person_model','person');
}
public function index()
{
$this->load->helper('url');
$this->load->view('person_view');
}
public function ajax_list()
{
$list = $this->person->get_datatables();
$data = array();
$no = $_POST['start'];
foreach ($list as $person) {
$no++;
$row = array();
$row[] = $person->firstName;
$row[] = $person->lastName;
$row[] = $person->gender;
$row[] = $person->address;
$row[] = $person->dob;
$data[] = $row;
}
$output = array(
"draw" => $_POST['draw'],
"recordsTotal" => $this->person->count_all(),
"recordsFiltered" => $this->person->count_filtered(),
"data" => $data,
);
//output to json format
echo json_encode($output);
}
以及最后一次创建以供查看。视图目录下的 person_view.php

创建表的 SQL ：
创建数据库crud；
使用杂物；
创建表persons (
id int(11) 无符号非空 AUTO_INCREMENT，
firstName varchar(100) 默认为空，
lastName varchar(100) 默认为空，
gender enum('male','female') 默认为空，
address varchar(200) 默认为空，
dob 日期默认为空，
主键 (id)
) ENGINE=InnoDB 默认字符集=utf8;
