Codeigniter 2.1 - Combining $data from the __construct and called function

Question

I have several $data which are called in almost all functions in controller. Is there a way to create this $data in __construct function and combine them with $data in called function? Example:

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

        $this->load->model('ad_model', 'mgl');
        $this->load->model('global_info_model', 'gi');
        $this->load->model('user_model', 'um');        
        $this->load->library('global_functions');
        $this->css = "<link rel=\"stylesheet\" href=\" " . CSS . "mali_oglasi.css\">";
        $this->gi_cat = $this->gi->gi_get_category();
        $this->gi_loc = $this->gi->gi_get_location();        
        $this->gi_type = $this->gi->gi_get_type();       
        }

    function index() {     
        $count = $this->db->count_all('ad');        
        $data['pagination_links'] = $this->global_functions->global_pagination('mali_oglasi', $count, 2);

        $data['title'] = "Mali Oglasi | 010";
        $data['oglasi'] =  $this->mgl->mgl_get_all_home(10);
        $data['loc'] = $this->gi_loc;
        $data['cat'] = $this->gi_cat;
        $data['stylesheet'] = $this->css;
        $data['main_content'] = 'mali_oglasi';

    $this->load->view('template',$data);
    }

If I want to put $data['loc'], $data['cat'] and $data['stylesheet'] in __construct I will have to call $this->data in $this->load->view('template',$data);

Is there a way to combine this two?

Add a private member to your controller and set it in the constructor as you need it:

private $data;

function __construct() {
    ...
    $this->data = array(...);
    ...
}

Then you can access this private member in all of your controllers actions inside the same controller class.

You can merge two arrays using the array union operator (+)^Docs:

$data = $this->data + $data;

This is basic PHP, you can use it for all your classes, be them controllers or something else. There is much use in learning the basics ;)

Well I am a self learned programmer, so I maybe skipped a few basic lessons :D

That has nothing to do with being self-learned or not. It's merely where to look :)

Sure, you could do it like this,

class ControllerName extends CI_Controller {

    private $_data = array();

    function __construct()
    {
        $this->_data['loc'] = this->gi_loc;
        $this->_data['cat'] = this->gi_cat;
        $this->_data['stylesheet'] = this->css;
    }

    function index()
    {
        // Your data

        // Merge them before the $this->load->view();
        $data = array_merge($this->_data, $data);
    }
}
