How to add new layout for admin dashboard - php

Question

In Zend Expressive, the layout is "default" into "templates" folder.
I would like to add "admin" folder into "templates" folder like that:
Templates
admin
app
admin-page.phtml
error
404.phtml
error.phtml
layout
default.phtml
default
app
home-page.phtml
error
404.phtml
error.phtml
layout
default.phtml
I've tried with the tutorials of Zend expressive to add new layout but no success for me...
class AdminPageHandler implements RequestHandlerInterface
{
private $template;
public function __construct(TemplateRendererInterface $template)
{
$this->template = $template;
}
public function handle(ServerRequestInterface $request) : ResponseInterface
{
$data = [
'admin' => 'layout::admin',
// or 'layout::admin',
// or 'layout::alternative',
];
$content = $this->template->render('pages::admin-page', $data);
return new HtmlResponse($content);
}
}
How can I add a new layout for my admin dashboard?
I would like to add new layout for my admin dashboard because the HTML script is different of my Home Application.

The template paths can be found in ConfigProvider class => __invoke method, under 'templates' => 'paths' or in getTemplates() method. There you should add a new path:
/**
* Returns the templates configuration
*/
public function getTemplates(): array
{
return [
'paths' => [
'app' => [__DIR__ . '/../templates/app'],
'error' => [__DIR__ . '/../templates/error'],
'layout' => [__DIR__ . '/../templates/layout'],
'admin' => [__DIR__ . '/../templates/admin'],
],
];
}
then your handler should look something like this
public function handle(ServerRequestInterface $request) : ResponseInterface
{
$data = [
'admin' => 'layout::admin',
// or 'layout::admin',
// or 'layout::alternative',
];
$content = $this->template->render('admin::app/admin-page', $data);
return new HtmlResponse($content);
}
