在 Shopware 6 中使用 ListingResult getCurrentFilter('properties') 筛选 ListingCriteria
Filter ListingCriteria using ListingResult getCurrentFilter('properties') in Shopware 6
问:
如何让它工作,以便我可以根据 getCurrentFilter('properties') 结果过滤条件?
以便所选属性可以包含在条件中。现在,由于事件序列,它不起作用。
我可以告诉 Symfony 重新加载页面来获取它吗?
有谁知道另一个事件来实现这一点?
<?php // declare(strict_types=1);
namespace CustomFilterBasedOnSelectedOptions\Subscriber;
class Subscriber implements EventSubscriberInterface
{
private ?array $currentPropertyOptions = null;
public static function getSubscribedEvents(): array
{
return [
ProductListingCriteriaEvent::class => 'ListingCriteria',
ProductListingResultEvent::class => 'ListingResult'
];
}
public function ListingResult(ProductListingResultEvent $event)
{
$properties = $event->getResult();
$this->currentPropertyOptions = $properties->getCurrentFilter('properties');
}
public function ListingCriteria(ProductListingCriteriaEvent $event): void
{
$event->getCriteria()->addAssociation('properties');
$event->getCriteria()->addAssociation('properties.group');
$currentPropertyOptions = $this->currentPropertyOptions;
/*
if (in_array('c0d02d1738fd4293a489695787e06b5c', $currentPropertyOptions)) {
$criteria = $event->getCriteria();
$criteria->addFilter(new MultiFilter(
MultiFilter::CONNECTION_OR,
[
new ContainsFilter('product.properties.name', 'Option1'),
new ContainsFilter('product.properties.name', 'Option2')
]
)
);
}
*/
}
}

如果我对你尝试执行的操作的假设是正确的,那么你不需要一个属性来记忆两个事件之间的筛选器值。构造筛选器时,它们将存储为 的扩展名。您只需要以足够低的优先级订阅,因此在调用侦听器时已经设置了分机。通过设置优先级,它应该足够低。Criteria
ProductListingCriteriaEvent
-200
然后只需检查是否设置了带有 的扩展名并包含 with the key ,以提取过滤器值。FilterCollection
Filter
properties
use Shopware\Core\Content\Product\Events\ProductListingCriteriaEvent;
use Shopware\Core\Content\Product\SalesChannel\Listing\Filter;
use Shopware\Core\Content\Product\SalesChannel\Listing\FilterCollection;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
class Subscriber implements EventSubscriberInterface
{
public static function getSubscribedEvents(): array
{
return [
ProductListingCriteriaEvent::class => [
['onListingCriteria', -200],
],
];
}
public function onListingCriteria(ProductListingCriteriaEvent $event): void
{
$criteria = $event->getCriteria();
$filters = $criteria->getExtension('filters');
if (!$filters instanceof FilterCollection) {
return;
}
$propertyFilter = $filters->get('properties');
if (!$propertyFilter instanceof Filter || !\is_array($propertyFilter->getValues())) {
return;
}
$currentPropertyOptions = $propertyFilter->getValues();
// ...
}
}

您是否知道一些 Shopware 6.5 更新可能会破坏这一点?更新到 6.5 后,我需要手动重新加载页面,无论哪种方式,下拉列表(带有勾选框)都会变得“粘性”。
