Can't Initialize Parent Controller from Subfolder in CodeIgniter 4-CodePudding

I have the following structure in CI4 project:

app
  pages
    Front.php
    Member.php
  manage
    Courses.php

Here are the routing rules:

$routes->group('pages', ['namespace' => 'App\Pages'], function ($routes) {
    $routes->resource('member', ['only' => ['index', 'show']]);

    $routes->group('manage', ['namespace' => 'App\Pages\Manage'], function ($routes) {
        $routes->resource('courses', ['only' => ['index', 'update']]);
    });
});

Front.php is the main controller.

namespace App\Pages;

use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;

class Front extends \CodeIgniter\Controller
{
    protected $me;

    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger) {
        parent::initController($request, $response, $logger);
        
        $this->me = $this->run();
        log_message('info', 'My id: ' . $this->me);
        
    }

    private function run() {
        return 10;
    }

    protected function showVal($val) {
        log_message('info', 'Value is: ' . $val);
    }
}

Member.php extends Front.php.

namespace App\Pages;

class Member extends Front
{
    protected $model;
    public function __construct()
    {
        log_message('info', 'My id in Member: ' . $this->me);
        helper('utils');
        $this->model = model('App\Models\MemberModel');
    }

    public function index() {}
    public function show($mid) {}
}

Accessing the URL website.com/pages/member produces the following log message:

My id: 10

My id in Member: 10

It means the front controller is properly initialized.

However, I'm failing to initialize the front controller from the subfolder controller.

namespace App\Pages\Manage;

use App\Pages\Front;

class Courses extends Front
{
    public function __construct()
    {
        log_message('info', 'My id in Courses: ' . ($this->me ?? 'Not available'));
    }

    public function index() {}
    
    public function update($cid) {
        $this->showVal(100);
    }
}

Accessing website.com/pages/manage/courses gives the following log:

My id in Courses is: not available

However, performing a PUT request on courses gives the log:

My id in Courses is: not available

Value is: 100

So the Courses controller is able to include the Front controller but can't get it initialized.

What am I missing?

I'm supposed to let it get initialized in the same manner as the Member controller gets.

Do I need to manually initialize it by calling parent::initController(...) in the courses class constructor?

Thanks for the help.

CodePudding user response：

In php __construct() doesn't call parent::__construct() automatically. initController() is also not called by any extending class automatically.

However calling (almost) any function from current instance will call initController(). You do instantiate a model in Member.php's constructor, which forced the shared instance.

A way to secure the initialization is just call initController() in extended constructors.
