Create a new application/controllers/Demo.php file and following the code.


defined('BASEPATH') OR exit('No direct script access allowed');

class Demo extends CI_Controller {

    function __construct() {
        $this->now_time = date('Y-m-d H:i:s');
    function update_demo(){
        $post_data['name'] = "Demo";
        $post_data['email'] = "";
        $post_data['updated_at'] = $this->now_time;

        $result = $this->demo_model->update('demo',$post_data, array("id" => 1));
            echo "Demo updated";
            echo "Demo not updated";

Step 2 : Create Model

Create a new application/models/Demo_model.php file and following the code. $this->db->update() function to update data in codeigniter.


class Demo_model extends CI_Model
    function __construct()
     * @param $table_name
     * @param $data_array
     * @param $where_array
     * @return mixed
    function update($table_name,$data_array,$where_array){
        $rs = $this->db->update($table_name, $data_array);
        return $rs;
