How to autoload helper functions in codeigniter 4 - geordy - 01-21-2017
I just downloaded CodeIgniter 4 from their official GitHub. They changed a lot from CodeIgniter 3. I want to use base_url() function in the view and for that, you need to load URL helper and in CodeIgniter 3 i autoloaded it in config/autoload.php file. But now they have entirely changed the structure of config/autoload.php file in CodeIgniter 4 and it is very confusing to me.
You can still use the base_url() function in your views in CodeIgniter 4 by using below code in your constructor of controller
Code:
helper('url');If anybody who used CodeIgnter 4 knows how to autoload helper functions like url by modifying autoload.php file please help me.

From the current CI4 docs it doesn't look like you can autoload helpers like in past versions, though I've not really dug into CI4 yet.

You can if you have a BaseController like the MY_Contoller in CI 3.

In the Controller docs it shows that you can use the helpers class property to have it loaded on a per-controller basis. If you want something loaded on every request, currently your best option is to use a base controller like InsiteFX mentioned. Though, you'd want to be careful you didn't overwrite any per-controller helpers:
Code:
class BaseController extends \CodeIgniter\Controller
{
protected $helpers = [];
public function __construct()
{
$this->helpers = array_merge($this->helpers, ['url', 'form']);
}
}
class UserController extends BaseController
{
protected $helpers = ['filesystem', 'number'];
}Or, even simpler, just load the helper in the BaseController constructor:
Code:
class BaseController extends \CodeIgniter\Controller
{
protected $helpers = [];
public function __construct()
{
helper(['url', 'form']);
}
}
