# Controller
|
||
|
|
|
||
|
|
The default controller of a node is `App\Core\Controller\Site\PageController::show`.
|
||
|
|
`PageController` extends `Symfony\Bundle\FrameworkBundle\Controller\AbstractController` and implements very basic features: a Response builder which retrieves the good template and injects variables to the view.
|
||
|
|
|
||
|
|
To create a custom controller, do this way:
|
||
|
|
|
||
|
|
```
|
||
|
|
// src/Controller/MyController.php
|
||
|
|
namespace App\Controller;
|
||
|
|
|
||
|
|
use App\Core\Controller\Site\PageController;
|
||
|
|
|
||
|
|
class MyController extends PageController
|
||
|
|
{
|
||
|
|
public function myAction()
|
||
|
|
{
|
||
|
|
if (!$this->siteRequest->getPage()) {
|
||
|
|
throw $this->createNotFoundException();
|
||
|
|
}
|
||
|
|
|
||
|
|
return $this->defaultRender($this->siteRequest->getPage()->getTemplate(), [
|
||
|
|
// view datas
|
||
|
|
]);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Then edit `config/packages/app.yaml` and add your controller:
|
||
|
|
|
||
|
|
```
|
||
|
|
core:
|
||
|
|
site:
|
||
|
|
controllers:
|
||
|
|
- {name: 'My action', action: 'App\Controller\MyController::myAction'}
|
||
|
|
```
|
||
|
|
|
||
|
|
If your controller represents entities and if the associated node is visible in the sitemap, you can use a `App\Core\Annotation\UrlGenerator` in annotations and implement a generator. See the example below.
|
||
|
|
|
||
|
|
```
|
||
|
|
// src/Controller/MyController.php
|
||
|
|
namespace App\Controller;
|
||
|
|
|
||
|
|
use App\Core\Annotation\UrlGenerator;
|
||
|
|
use App\Core\Controller\Site\PageController;
|
||
|
|
use App\UrlGenerator\MyEntityGenerator;
|
||
|
|
|
||
|
|
class MyController extends PageController
|
||
|
|
{
|
||
|
|
/**
|
||
|
|
* @UrlGenerator(service=MyEntityGenerator::class, method="myAction")
|
||
|
|
*/
|
||
|
|
public function myAction(MyEntity $entity)
|
||
|
|
{
|
||
|
|
// do stuff
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
```
|
||
|
|
// src/UrlGenerator/MyEntityGenerator
|
||
|
|
namespace App\UrlGenerator;
|
||
|
|
|
||
|
|
use App\Repository\MyEntityRepositoryQuery;
|
||
|
|
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
|
||
|
|
|
||
|
|
class MyEntityGenerator
|
||
|
|
{
|
||
|
|
protected MyEntityRepositoryQuery $query;
|
||
|
|
protected UrlGeneratorInterface $urlGenerator;
|
||
|
|
|
||
|
|
public function __construct(MyEntityRepositoryQuery $query, UrlGeneratorInterface $urlGenerator)
|
||
|
|
{
|
||
|
|
$this->query = $query;
|
||
|
|
$this->urlGenerator = $urlGenerator;
|
||
|
|
}
|
||
|
|
|
||
|
|
public function myAction(): array
|
||
|
|
{
|
||
|
|
$entities = $this->query->create()->find();
|
||
|
|
|
||
|
|
$urls = [];
|
||
|
|
|
||
|
|
foreach ($entities as $entity) {
|
||
|
|
$urls[] = $this->urlGenerator->generate(
|
||
|
|
'the_route_name',
|
||
|
|
[
|
||
|
|
'entity' => $entity->getId(),
|
||
|
|
],
|
||
|
|
UrlGeneratorInterface::ABSOLUTE_URL
|
||
|
|
);
|
||
|
|
}
|
||
|
|
|
||
|
|
return $urls;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
