Event listener
Introduction
It is possible to use various custom event listener to use custom location loading logic. If you need a modified sorting or locations based on other constraints then the provided, it is possible to override the loading completely.
Adding event listeners
Add the following code to the Configuration/Services.yaml of your sitepackage to use the example listener.
namespace Evoweb\StoreFinder\EventListener;
use Evoweb\StoreFinder\Controller\Event\MapGetLocationsByConstraintsEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;
class MapGetLocationsByConstraintsEventListener
{
#[AsEventListener('storefinder_mapcontroller_locationsfetched', MapGetLocationsByConstraintsEvent::class)]
public function __invoke(MapGetLocationsByConstraintsEvent $event): void
{
}
}More explanation for your custom event listener can be found in the tutorial <_
Additional configuration
Performance improvement
When using event listeners it's advised to set typoscript setup
plugin.
to improve performance. By doing so, all default fetching will be disabled.
plugin.tx_storefinder.settings.disableLocationFetchLogic = 1Listener must follow the symfony/event concept [https://symfony.com/doc/current/event_dispatcher.html]
Radius not automatically detected
If you use a custom location loading mechanism, the location::distance property will be empty. At least if you do not fill them on your own. In case the distance is empty the default zoom level detection has nothing to work with. In this case, you need to set the zoom level in the template OR the radius in TypoScript
plugin.tx_storefinder.settings.defaultConstraint.radius = 20Modify locations in StoreFinderMiddleware
It's possible to change locations records from store finder middleware before sending the json response. Use the ModifyMiddlewareLocationsListener as an example of how to change values.
The registration got simplified in TYPO3 13.x
use Evoweb\StoreFinder\Middleware\Event\ModifyMiddlewareLocationsEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;
class ModifyMiddlewareLocationsEventListener
{
#[AsEventListener('your-extension-identifier', ModifyMiddlewareLocationsEvent::class)]
public function __invoke(ModifyMiddlewareLocationsEvent $event): void
{
}
}
