<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\EventListener;

use Freshworkx\BmImageGallery\Event\AfterCollectionInfoResolvedEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-ext/add-metadata',
    event: AfterCollectionInfoResolvedEvent::class
)]
final readonly class AddMetadataListener
{
    public function __invoke(AfterCollectionInfoResolvedEvent $event): void
    {
        $info = $event->getCollectionInfo();

        // Add formatted date
        if ($info['date']) {
            $info['formattedDate'] = date('d.m.Y', $info['date']);
        }

        // Add SEO data
        $info['metaDescription'] = sprintf(
            'Gallery "%s" with %d images',
            $info['title'],
            $info['itemCount']
        );

        $event->setCollectionInfo($info);
    }
}

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\EventListener;

use Freshworkx\BmImageGallery\Event\AfterCollectionInfoResolvedEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-ext/add-custom-fields',
    event: AfterCollectionInfoResolvedEvent::class
)]
final readonly class AddCustomFieldsListener
{
    public function __invoke(AfterCollectionInfoResolvedEvent $event): void
    {
        $info = $event->getCollectionInfo();

        // Add custom fields
        $info['formattedDate'] = date('d.m.Y', $info['date']);
        $info['hasMultipleImages'] = $info['itemCount'] > 1;

        $event->setCollectionInfo($info);
    }
}

Modify Existing Fields

This example shows how to modify existing collection fields.

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\EventListener;

use Freshworkx\BmImageGallery\Event\AfterCollectionInfoResolvedEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-ext/modify-title',
    event: AfterCollectionInfoResolvedEvent::class
)]
final readonly class ModifyTitleListener
{
    public function __invoke(AfterCollectionInfoResolvedEvent $event): void
    {
        $info = $event->getCollectionInfo();

        // Modify title
        $info['title'] = '[Gallery] ' . $info['title'];

        $event->setCollectionInfo($info);
    }
}

Add External Data

This example demonstrates enriching collections with external data.

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\EventListener;

use Freshworkx\BmImageGallery\Event\AfterCollectionInfoResolvedEvent;
use MyVendor\MyExtension\Service\StatisticsService;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-ext/add-statistics',
    event: AfterCollectionInfoResolvedEvent::class
)]
final readonly class AddStatisticsListener
{
    public function __construct(
        private StatisticsService $statisticsService
    ) {}

    public function __invoke(AfterCollectionInfoResolvedEvent $event): void
    {
        $info = $event->getCollectionInfo();

        // Add external data
        $info['downloadCount'] = $this->statisticsService
            ->getDownloadCount($info['identifier']);
        $info['viewCount'] = $this->statisticsService
            ->getViewCount($info['identifier']);

        $event->setCollectionInfo($info);
    }
}
