I am trying to save dates(start and end date) from datepicker and description of the event.

My Controller

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Calendar extends CI_Controller
{

     public function __construct() {
        Parent::__construct();
        $this->load->model("calendar_model");
    }

     public function index()
     {
          $this->load->view("user/calendar.php", array());
     }


     public function add_event() 
{
    /* Our calendar data */
    $sched_desc = $this->input->post("sched_desc", TRUE);
    $start = $this->input->post("start", TRUE);
    $end = $this->input->post("end", TRUE);


    $this->calendar_model->add_event(array(
       "sched_desc" => $sched_desc,
       "start" => $start,
       "end" => $end
       )
    );

    redirect(site_url("calendar"));
}
}


?>

My Model

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

class Calendar_model extends CI_Model {


/*Create new events */

    Public function addEvent()
    {

    $sql = "INSERT INTO events (title,events.start,events.end,description, color) VALUES (?,?,?,?,?)";
    $this->db->query($sql, array($_POST['title'], $_POST['start'],$_POST['end'], $_POST['description'], $_POST['color']));
        return ($this->db->affected_rows()!=1)?false:true;
    }

}

?>

I wanted to create a schedule setter wherein admin can set schedule to a specific event and should have start date and end date and also description of the event.
