Answer 1

you should extend model like this in codeIgniter

class Modelname extends CI_Model
  {
   function __construct()
    {
          parent::__construct();
    }
  }

Answer 2

Well actually the study guide is of old version of CI, where you used to extend your models from Model class as show in the guide. But now it has been changed. Now you have to extend it from CI_Model, same goes for Controller.

For controllers

class Employee_controller extends CI_Controller
{
  //load the constructor
  function __construct()
  {
    //inherit the parent constructor
    parent::__construct();
  }
}

and for models:

class Employee_model extends CI_Model
{
  //load the constructor
  function __construct()
  {
    //inherit the parent constructor
    parent::__construct();
  }
}

Answer 3

You must create a model in the model folder like my_model.php

And create the class like

class My_model extends CI_Model
{
   function __construct()
   {
      parent::__construct();
   }
}

Remember the class and the file should be same.

Answer 4

Use like this

<?php

class Employee_model extends CI_Model
{
     //load the constructor
     function __construct()
     {
          //inherit the parent constructor
          parent::__construct();
     }
}
