Is it possible to add the following code to multiple functions without retyping the code individually?
$user_id = $this->tank_auth->get_user_id();
$data['row'] = $this->Profile_model->profile_read($user_id);
I tried putting the variables in the constructor but I get undefined variables for both.
you could turn it in to a private function of the controller, i.e.
private function get_user_id()
{
$user_id = $this->tank_auth->get_user_id();
return $this->Profile_model->profile_read($user_id);
}
And then in every function in your controller do:
$data['row'] = $this->get_user_id();
protected and not private ?
protected offers a greater advantage.It only saves you one line but thats a 100% decrease in code lines!
private function rowData(){
$user_id = $this->tank_auth->get_user_id();
return $this->Profile_model->profile_read($user_id);
}
$data['row'] = $this->rowData();
Well if you put it in the constructor you'd need:
$this->user_id = $this->tank_auth->get_user_id();
$this->data['row'] = $this->Profile_model->profile_read($user_id);
Cannot access empty property for bothYou can have this as the controller's constructor:
class Example extends CI_Controller {
protected $user_id;
function __construct()
{
parent::__construct();
$this->load->library('tank_auth');
$this->load->model('Profile_model');
$this->user_id = $this->tank_auth->get_user_id();
$data['row'] = $this->Profile_model->profile_read($this->user_id);
$this->load->vars($data);
}
}
and you will have access to $row in any subsequent views loaded from that constructor, as well as be able to use $this->user_id in any of the functions of that controller.

$user_id wherever I try to use it in controller functions.
Did you load the tank_auth library or set it to autoload?
