Your code isn't working because you have bypassed the "middleware", which is what sets the current user from the session data.
Summary: webtrees is built around request handlers and middleware.
A request handler takes an HTTP request, and generates an HTTP response.
Middleware are wrappers around this process. They are called before an after. Thus they can modify the request, modify the response, etc.
To create a new page, you need to create a module.
There are lots of example modules here:
github.com/webtrees/
Your module needs the following
1) register a route (i.e. a URL), and set itself as the request handler for that route. Use the following function in your module
public function boot(): void
{
Registry::routeFactory()->routeMap()
->get(static::class, '/foo/bar/whatever', $this);
}
You'd create URLs to this page using
route(YourModule::class, )
Your module would need to implement RequestHanderInterface and have a function handle()
Now, requests to this URL will be passed to your module.
You can use Auth::user(), etc. here
To send output back to the browser, don't use echo.
Instead
return response($your_html);
To send output with webtrees headers/footers, you'd use the ViewResponseTrait and this:
return $this->viewResponse(...)
