Answer 1

The way you've written it, your Get_notes Model is only available within your index() function.
To make your Get_notes Model available to all functions within a single Controller, load it within that Controller's constructor function...
class Notes extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('get_notes'); // available to all functions within Notes
}
....
To make your Get_notes Model available globally to all functions in any CI Controller, put it in your $autoload['model'] array within the autoload.php file located at application/config/autoload.php...
$autoload['model'] = array('get_notes'); // available to all functions in your CI application
→ Note that it's supposed to be written in all lower-case no matter how you reference it later.
$this->load->model('get_notes');
$this->get_notes->add_notes($data);
See:
Class Constructors
If you intend to use a constructor in any of your Controllers, you MUST place the following line of code in it:
parent::__construct(); // Notice there is no dollar sign
Anatomy of a Model:
Where Model_name is the name of your class. Class names must have the first letter capitalized with the rest of the name lowercase. Make sure your class extends the base Model class.
Loading a Model:
Your models will typically be loaded and called from within your controller methods. To load a model you will use the following method:
$this->load->model('model_name');
Once loaded, you will access your model methods using an object with the same name as your class:
$this->model_name->method();
Auto-loading Resources
To autoload resources, open the application/config/autoload.php file and add the item you want loaded to the autoload array. You’ll find instructions in that file corresponding to each type of item.

An codeigniter model call is case sensitive therefore to get an model you should use
$this->get_notes->a_function_inside_the_model ();
Also note that the name inside the model folder should always start with a uppercase.
Whenever we run codeigniter on localhost servers like wamp server these problems dont exist but on a live server they will.
Hope this was helpful

Answer 3

Put $this->load->model('Get_notes'); in the insert() function.
If you want to use it globally, put it in a constructor.

Answer 4

Your get_notes model is only loaded in the index function. You cannot load the model in the index function and use it in any other function without having to load it again.
I'm thinking you're trying to load the model once and use it throughout your controller. To do this, you have to load it in the __construct method instead. Your code should be similar to this:
<?php
class Notes extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('Get_notes');
}
public function index()
{
$data['notes'] = $this->Get_notes->get_mm();
$this->load->view('show', $data);
}
public function insert()
{
$title = 'Something';
$text = 'Something else';
$data = [
'title' => $title,
'text' => $text
];
$this->Get_notes->add_notes($data);
}
}
