Proper way to override registration behavior

[gl2007]

I wanted to customize registration behavior, so extended RegisterController and tried to use getValidationRules. I wanted to reuse the built-in validation logic and some other pieces.

I got "Error: Typed property CodeIgniter\Shield\Controllers\RegisterController::$tables must not be accessed before initialization".

Note that I am doing "new MyRegisterController()) and then calling ->method().

Assuming that initController has to be mandatorily overridden, I wrote this:

public function initController(
        RequestInterface $request,
        ResponseInterface $response,
        LoggerInterface $logger
    ): void {
        parent::initController(
            $request,
            $response,
            $logger
        );
}

but that one gave me Fatal error about some compatibility which I did not capture.

Can you help?

Can you try the following change?

I was thinking about making that protected. However, it didn't work and still gave the same error. Note that I have removed the "initController" method now.

This is the way to customize the controller and I have no problem with it. Or at least I didn't get it right.

My Routes.php :

service('auth')->routes($routes, ['except' => ['register']]);

$routes->get('register', '\App\Controllers\RegisterController::registerView');
$routes->post('register', '\App\Controllers\RegisterController::registerAction');

my App\Controllers\RegisterController.php:

<?php

namespace App\Controllers;

use CodeIgniter\Shield\Controllers\RegisterController as ShieldRegisterController;

class RegisterController extends ShieldRegisterController
{
     /**
     * Displays the registration form.
     *
     * @return RedirectResponse|string
     */
    public function registerView(){
        return 'override';
    }

    public function myMethod(){
        return 'My Method!!';
    }
}

Not sure if I want to go that route as I am not changing the default registration but only providing another registration route to be done by an admin or someone with permissions.

Thanks for your answers. Here is how I solved it:
First made the "$tables" protected as @kenjis suggested.

Next, I added the code below to my registration method at the top.
$authConfig = config('Auth'); $this->tables = $authConfig->tables;

Then I removed all "user" registration based actions/redirections etc. and kept the validations/events/group registration in place. It all worked smoothly.

Thanks!
