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?

Answer 1

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;
