How to write component in codeigniter - codeigniter

Question

I want to know how can I write a component in codeigniter
I have worked with symfony1.4 and there there is something include_component("name",dataarray()) that we can load a component ( it's actually an action ).
I already know that we have $this->load->view('admin/template/login') for loading a view, But I want to know is there any way to call an action like this?
this->load(news/list,array('date'=>xxx-xx-xx))
thanks anyways

Answer 1

you can this through the use of libraries, helpers or plugins.
an example of using a library class in application/library called LoadNews.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class LoadNews {
public function showList($date_array) {
// do stuff with date array
}
}
/* End of file LoadNews.php */
/* Location: ./application/libraries/LoadNews.php */
then in your controller, you call
$this->load->library('LoadNews');
$this->loadnews->showList(array('date'=>'2014-12-19'));

Answer 2

Yes, you can do this from CI 3.
In your Controller or View just call $this->load->view(view, data);
Example:
<?php
defined('BASEPATH') or die('No direct script allowed');
class PageController extends CI_Controller
{
public function index()
{
$data = [
'names' => ['john', 'doe'],
'ages' => ['24', '30']
];
$this->load->view('index', $data);
}
}
?>
And in your view you can access 'names' and 'ages' as $names and $ages respectively.
You can do this in your view:
<?php
echo '<pre>';
print_r($names);
print_r($ages);
echo '</pre>';
?>
The result:
Array (
[0] => john
[1] => doe
)
Array (
[0] => 24
[1] => 30
)
