Passing data to view from controller using templates

Controller:

public function home(){
$data['page_title'] = 'Home';
$data['navbar_content'] = $this->model->get($var);
$data['page_content'] = $this->model->get($var1);

$this->load->view('template/header');
$this->load->view('template/navbar');
$this->load->view('pages/home');
$this->load->view('template/footer');
}

Using the sample code above, Since codeigniter only allows the passing of variables/data through an array or object from controller to the view then what is the 'right' way to pass my data?

I could simply pass the data when loading the header and things will still work out fine. 

$this->load->view('template/header', $data);
$this->load->view('template/navbar');
$this->load->view('pages/home');
$this->load->view('template/footer');

But that doesn't seem 'right' to me, i guess i wanted things to be clear in my code for example:

$this->load->view('template/header', $title);
$this->load->view('template/navbar', $navbar_content);
$this->load->view('pages/home', $page_content);
$this->load->view('template/footer');

The above is clear cut and there is a distinction to the data that are being passed.

But since i can't do that, is there a 'correct' way of doing this? or am i thinking too much on it?

I neglected to mention, I could simply make 2 arrays to pass to the view. I thought this is wrong in the first place since i'm going out of my way to make 2 arrays to pass just so i can pass a single string variable to my header page.

Ofcourse when i pass more data to my navbar then it would make sense to me.

This is the correct way according to the documentation: https://codeigniter.com/userguide3/general/views.html

Data is passed from the controller to the view by way of an array or an object in the second parameter of the view loading method.

You should also look on: Codeigniter: Best way to structure partial views

You should structure you views hierarchically. 

$this->load->view('template/header', ["title" => $title]);
$this->load->view('template/navbar', ["navbar_content" => $navbar_content]);
$this->load->view('pages/home', ["page_content" => $page_content]);
$this->load->view('template/footer');

CodeIgniter passes data from controllers to views.

You need to pass $data to views.

You will pass an array with its keys be strings or even arrays (multi-dimensional arrays also).

So, you need to pass it to every view you are using $data.

$this->load->view('template/header', $data);
$this->load->view('template/navbar', $data);
$this->load->view('pages/home', $data);
$this->load->view('template/footer', $data);

And in your view, you can access $data with keys.

For example:

if your data is 

$data['header_banner'] = 'Header Banner';

In your view, you can access this value by:

echo $header_banner;

Observe that to the key in $data, you just need to add a $ and you can access that variable.

Its something line PHP's in built function extract()
