Language localization compatibility

[atakanau]

I am working on language localization. I am using "Shield" as "Third Party".

I prepare the global variables in:
\app\Controllers\BaseController.php

public function initController(RequestInterface $request, ...)
{
	// Do Not Edit This Line
	parent::initController($request, $response, $logger);
	// Preload any models, libraries, etc, here.
	// E.g.: $this->session = \Config\Services::session();
	$this->helpers = array_merge($this->helpers, ['setting']);
	
	// localization >>>
	$this->viewData['locale'] = [];
	$this->viewData['locale']['current_code'] = $request->getLocale();
	$this->viewData['locale']['codes'] = $request->config->supportedLocales;
	$this->viewData['locale']['lang_switcher'] = array(
		 'en'=>[ 'html_lang'=>'en-US'
			,'html_dir'=>'ltr'
			,'codename'=>'English'
		]
		,'es'=>[ 'html_lang'=>'es-ES'
			,'html_dir'=>'ltr'
			,'codename'=>'Español'
		]
	);
	foreach($request->config->supportedLocales as $code){
		// Other language variable values ​​etc.

I discovered following setting the for URL routing:
\app\ThirdParty\shield\src\Config\AuthRoutes.php

    public array $routes = [
        'register' => [
            [
                'get',
                '{locale}/register', // <- old value: 'register'

In this situation; [locale]/login, [locale]/login/magic-link and [locale]/register works.

I have activated the E-Mail Activation. I had to make the following new setting for redirect by page (url) language:
\app\ThirdParty\shield\src\Controllers\RegisterController.php

// If an action has been defined for register, start it up.
$hasAction = $authenticator->startUpAction('register', $user);
if ($hasAction) {
    return redirect()->to($this->request->getLocale().'/auth/a/show');
    // return redirect()->to('auth/a/show'); // <- old
}

However, I can't get to my viewData variable before the page at [locale]/auth/a/show is displayed.
\app\ThirdParty\shield\src\Traits\Viewable.php

protected function view(string $view, array $data = [], array $options = []): string
{
    if( isset($this->viewData) ) // [locale]/register ok ; fails on [locale]/auth/a/show
        $data = array_merge($this->viewData, $data);
    return view($view, $data, $options);
}

I need to edit the action address of the form. I need access to current language code (and other variables).
\app\ThirdParty\shield\src\Views\email_activate_show.php

<form action="<?= site_url('auth/a/verify') ?>" method="post">

<form action="<?= site_url($locale['current_code'].'/auth/a/verify') ?>" method="post">

How can I access the viewData variable in all "views"?

How can I access the viewData variable in all "views"?

Pass the variable to views.

view($view, ['viewData' => $this->viewData], $options);

😔 Ok.
As I mentioned earlier,briefly:
I prepare my variable in \app\Controllers\BaseController.php:
protected $viewData = [];
I can access the $this->viewData in APPPATH\ThirdParty\shield-dev\src\Traits\Viewable.php when the url is [locale]/login, [locale]/login/magic-link and [locale]/register. But $this->viewData is undefined when the url is [locale]/auth/a/show.

You cannot access $viewData in a view unless you pass the variable to the view.
CodeIgniter\Shield\Authentication\Actions\EmailActivator is not a Controller.
Read the ActionController code.

I did not edit the CodeIgniter\Shield\Authentication\Actions\EmailActivator file. Please read that error again. As you say:

Pass the variable to views.

view($view, ['viewData' => $this->viewData], $options);

I modified the APPPATH\ThirdParty\shield-dev\src\Traits\Viewable.php; I added the $this->viewData as a parameter to the view method. Controller calls this view method. But $this->viewData is undefined. So, result: ErrorException. ( Again: I can access the $this->viewData in APPPATH\ThirdParty\shield-dev\src\Traits\Viewable.php when the url is [locale]/login, [locale]/login/magic-link or [locale]/register. Same code fails on [locale]/auth/a/show ! )

Anyway,

Read the ActionController code.

I am accessing the $this->viewData inside the show and verify methods in shield-dev\src\Controllers\ActionController.php. How do I pass $this->viewData to view? Sorry, I'm confused.

[kenjis]

This is just an example. Don't see it as a correct answer for your case.

view($view, ['viewData' => $this->viewData], $options);

[kenjis]

It seems you don't understand what is a class in PHP.

$this->viewData is a property in the instance.

Undefined property: CodeIgniter\Shield\Authentication\Actions\EmailActivator::$viewData

You do not define the property $viewData in EmailActivator.
So there is no wonder the error occurs.

[kenjis]

I recommend you set the viewData to the View instance with setVar() in your controller.
See https://codeigniter4.github.io/CodeIgniter4/outgoing/view_renderer.html

Thank you. viewData() is worked. 👌
\app\Controllers\BaseController.php:

  // localization >>>
  $this->viewData['locale'] = [];
  $this->viewData['locale']['current_code'] = $request->getLocale();
  $this->viewData['locale']['codes'] = $request->config->supportedLocales;
  // other custom values...
  $view = \Config\Services::renderer();
  $view->setData($this->viewData);
