Hi all , could you help me to create update function from these code:
Controller:

<?php


class BooksController extends CI_Controller{


    public function __construct() {
        parent::__construct();

       // $this->load->helper('url');
      //  $this->load->helper('form');
       // $this->load->library('form_validation');
       // $this->load->helper('html');
      //  $this->load->model("BooksModel");
    }
    function getAuthors(){
        $config['base_url']=site_url("/BooksController/getAuthors/");
        $config['total_rows']=$this->BooksModel->record_count();
        $config['per_page']=3;
        $this->pagination->initialize($config);

        $data['Authors'] = $this->BooksModel->getAuthors(3,$this->uri->segment(3));
        foreach ($data['Authors'] as &$row) {
           $id=$row['AuthorID']; 
         $img = $row['Image'];
         $row['Image'] = img("assets/images/thumbs/".$img);
         $row['actions']='<a href="'. site_url("BooksController/deleteAuthor/".$id).'"onclick="return checkDelete();">Delete</a>';
         $row['actionsOnUpdate']='<a href="'. site_url("BooksController/updateAuthor/".$id).'"onclick="return checkUpdate();">Update</a>';
        }

        $this->load->library('table');
        $this->load->view('viewAllAuthors',$data);
    }
    function deleteAuthor($authorToDelete){
      $deleteRows = $this->BooksModel->deleteAuthor($authorToDelete);
       $data['title']="Delition attempt" ; 
       if($deleteRows >0){
          $data['msg']=$deleteRows."author(s) has been deleted";
          $this->load->view('messagePage',$data);
       }
 else {
         $data['img'] ="There was an error deliting the author with an id of".$authorToDelete;
         $this->load->view('messagePage',$data);
       }
    }
       function updateAuthor($authorToUpdate){
      $updateRows = $this->BooksModel->updateAuthor($authorToUpdate);
       $data['title']="Update attempt" ; 
       if($updateRows >0){
          $data['msg']=$updateRows."author(s) has been updated";
          $this->load->view('messagePage',$data);
       }
 else {
         $data['img'] ="There was an error updating the author with an id of".$authorToUpdate;
         $this->load->view('messagePage',$data);
       }
    }

    function getAuthorByID(){

        $this->load->helper('form');


        if($this->input->post('submitAuthorID')){
            //echo "form submitted";

              $data =$this->BooksModel->getAuthorByID();
           // $this->load->helper('form');

            if($data == null)
            {
                $data['msg']=" The author ".$this->input->post('AuthorID'). "could not be found";
                $this->load->view('error',$data);
            return;
            }




            $this->load->view('showAuthorDetails',$data);
            return;


        }
        $this->load->view('getAuthorByID');
    }
    function handleInsert(){
        if($this->input->post('submitInsert'))
        {
        ($this->form_validation->set_rules('AuthorID','Author ID','required'));
        ($this->form_validation->set_rules('firstName','First Name','required'));
        ($this->form_validation->set_rules('lastName','Last Name','required'));
        ($this->form_validation->set_rules('yearBorn','Year Born','required'));

        $data['AuthorID']=$this->input->post('AuthorID');
        $data['firstName']=$this->input->post('firstName');
        $data['lastName']=$this->input->post('lastName');
        $data['yearBorn']=$this->input->post('yearBorn');

        if($this->form_validation->run()==FALSE){
            $this->load->view('insertAuthor',$data);
            return;
        }
        if ($this->BooksModel->insertAuthor()) {
                $data['message'] = "The insert has been successful";
            } else {
                $data['message'] = "Error on insert";
            }
            $this->load->view('displayMessage',$data);
        return;
        }

    $data['AuthorID'] = "";
    $data['firstName'] = "";
    $data['lastName'] = "";
    $data['yearBorn'] = "";
    $this->load->view('insertAuthor',$data);

}
}

Model:

<?php

class BooksModel extends CI_Model{
    public function __construct() {


        $this->load->database();
    }

    public function getAuthors($limit,$offset){
        $this->db->limit($limit,$offset);
        $resultSet = $this->db->get("authors");
        return $resultSet->result_array();
    }

    function getAuthorByID(){
        $id =$this->input->post('authorID');

        $resultSet = $this->db->get_where('authors',array('authorID'=>$id));

        return $resultSet->row_array();
    }
    public function insertAuthor(){
        $recordToInsert = array(
            'authorID'=>$this->input->post('authorID'),
            'firstName'=>$this->input->post('firstName'),

        );

        $affectedRows = $this->db->affected_rows();
        if ($affectedRows == 0) {

I don't understand why you have duplicate code in two different files. From CI documentation, the model will have the methods like insert, update etc. The controller shuld then load the model and call the relevant method. The controller shouldn't duplicate the methods.
