Question

I am developing a CRM for our agency in Codeigniter and I have a question that I can’t seem to find a solid answer on. If I have a task that I do on the majority of methods in a controller, is there any way to define that action only once? For instance…

Every view call gets passed the $data variable, like so…

$this->load->view('templates/template.php', $data);

So if I am doing something like getting the admins information in every function of the controller, how can i tell it to do that action ONE time and pass it to all my functions.

Like this…

$data['admin'] = $this->Crm_model->get_admin();

I’ve tried putting that ^ in the constructor and it doesn’t work. Any ideas?

If you do:

$data['admin'] = $this->Crm_model->get_admin();

in the constructor, $data‘s scope is limited to the constructor. You need to create it as a class property so it is scoped to the entire class. Do this instead

$this->data['admin'] = $this->Crm_model->get_admin();

in the constructor, and then in other methods, you can access the array by doing $this->data

Here’s an example:

class Foobar extends CI_Controller {

    public function __construct() {
        $this->data['foo'] = "bar";
    }

    public function index() {
        // use the class property data here to add more info to it
        $this->data['hello'] = "world";

        // now pass this to the view
        $this->load->view('myView', $this->data);
        // myView will receive both $foo and $hello

    }
}
