在 Shopware 中加载产品的所有变体 (PHP)

Question

我正在尝试加载产品的所有变体。

在使用 google 时，我发现了这个代码片段：

class ProductViewSubscriber implements EventSubscriberInterface
{
    private EntityRepositoryInterface $productRepository;

    public function __construct(EntityRepositoryInterface $productRepository)
    {
        $this->productRepository = $productRepository;
    }

    public function getVariantsOfProduct(SalesChannelProductEntity $product, Context $context): EntitySearchResult
    {
        $parentProduct = $product->getParent();
        if ($parentProduct != null) {
            // We need the parent product to find all variants
            $product = $parentProduct;
        }

        $criteria = new Criteria();
        $criteria->addFilter(new EqualsFilter('product.parentId',
            $product->getUniqueIdentifier()));

        return $this->productRepository->search($criteria, $context);
    }

    public static function getSubscribedEvents(): array
    {
        return [
            ProductPageLoadedEvent::class => ['addVariants'],
        ];
    }

    public function addVariants(ProductPageLoadedEvent $pEvent)
    {
        $products = $this->getVariantsOfProduct($product = $pEvent->getPage()->getProduct(), $pEvent->getContext());
        $matchingVariants = $products->getElements();
    }
}

但是使用代码片段只返回一个空列表，尽管该产品肯定有变体。我该如何修复此代码？

Answer 1

我认为下面一行是错误的：
$criteria->addFilter(new EqualsFilter('product.parentId', $product->getUniqueIdentifier()));

应该是：
$criteria->addFilter(new EqualsFilter('parentId', $product->getId()));
因为您已经使用 productRepository 进行搜索，所以属性只是 parentId.

Answer 2

它应该像这样工作。

<?php

namespace TestPlugin\Subscriber;

use Shopware\Core\Framework\Context;
use Shopware\Core\Framework\DataAbstractionLayer\EntityRepositoryInterface;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Criteria;
use Shopware\Core\Framework\DataAbstractionLayer\Search\EntitySearchResult;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Filter\EqualsFilter;
use Shopware\Storefront\Page\Product\ProductPageLoadedEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class ProductPageLoadedSubscriber implements EventSubscriberInterface
{
    private EntityRepositoryInterface $productRepository;

    public function __construct(EntityRepositoryInterface $productRepository)
    {
        $this->productRepository = $productRepository;
    }

    public static function getSubscribedEvents(): array
    {
        return [
            ProductPageLoadedEvent::class => 'addVariants'
        ];
    }

    public function addVariants(ProductPageLoadedEvent $pEvent)
    {
        $product = $pEvent->getPage()->getProduct();

        if (empty($productParentId = $product->getParentId())) { // Main product or has no variants
            return;
        }

        $products = $this->getVariantsOfProduct($productParentId, $pEvent->getContext());
        $matchingVariants = $products->getElements();

        var_dump($matchingVariants);
    }

    public function getVariantsOfProduct(string $productParentId, Context $context): EntitySearchResult
    {
        $criteria = new Criteria();
        $criteria->addFilter(new EqualsFilter('parentId', $productParentId));

        return $this->productRepository->search($criteria, $context);
    }
}

据我所知，Shopware 总是加载一个变体，因此检查 ParentId 很重要，它提供了主要产品 ID，您可以使用此 ID 找出所有变体。
