Magento 2使用类别标题获取类别ID

我想通过使用这种功能仅通过使用类别标题来获取类别ID。

->load($categoryTitle, 'title')
->getId();

用例：按标题获取类别ID，并将ID数据放入迁移脚本中的数组。

您可以通过集合来做到这一点：

首先，您需要CategoryFactory在类构造函数中注入a 。

Magento 2.0和2.1：

public function __construct(
    ...
    \Magento\Catalog\Model\CategoryFactory $categoryFactory
) {
    $this->_categoryFactory = $categoryFactory;
    parent::__construct(...);
}

然后，您可以在课程中的其他任何地方执行以下操作：

$collection = $this->_categoryFactory->create()->getCollection()->addAttributeToFilter('name',$categoryTitle)->setPageSize(1);

if ($collection->getSize()) {
    $categoryId = $collection->getFirstItem()->getId();
}

Magento 2.2：

public function __construct(
    ...
    \Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $collecionFactory
) {
    $this->_collectionFactory = $collecionFactory;
    parent::__construct(...);
}

然后，您可以在课程中的其他任何地方执行以下操作：

$collection = $this->collecionFactory
                ->create()
                ->addAttributeToFilter('name',$categoryTitle)
                ->setPageSize(1);

if ($collection->getSize()) {
    $categoryId = $collection->getFirstItem()->getId();
}

可以使用被认为是最佳实践的服务合同来完成。

protected $categoryList;

    /**
     * @var SearchCriteriaBuilder
     */
    protected $searchCriteriaBuilder;

    /**
     * @var FilterBuilder
     */
    protected $filterBuilder;

public function __construct(
        ------------
        CategoryListInterface $categoryList,
        SearchCriteriaBuilder $searchCriteriaBuilder,
        FilterBuilder $filterBuilder,
        -----------------
    )
    {
        $this->categoryList = $categoryList;
        $this->searchCriteriaBuilder = $searchCriteriaBuilder;
        $this->filterBuilder         = $filterBuilder;
        parent::__construct(----------);
    }

public function getNameCategory()
    {
        $enableFilter[] = $this->filterBuilder
            ->setField(\Magento\Catalog\Model\Category::KEY_NAME)
            ->setConditionType('like')
            ->setValue(self::CATEGORY_NAME_HELP) // name of the categroy on const
            ->create();


        $searchCriteria = $this->searchCriteriaBuilder
            ->addFilters($enableFilter)
            ->create();

        $items = $this->categoryList->getList($searchCriteria)->getItems();

        if(count($items) == 0)
        {
            return FALSE;
        }

        foreach ($items as $helpCategory)
        {
            $CategoryId = $helpCategory->getId()
        }
return $CategoryId;
    }

您可以使用完成此操作name，

$title = 'womens';
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$collection = $_categoryFactory->create()->getCollection()->addFieldToFilter('name',$title);
echo "<pre>";
print_r($collection->getData());
exit;

尝试下面的Phtml文件代码：

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$_categoryFactory = $objectManager->get('Magento\Catalog\Model\CategoryFactory');

$categoryTitle = 'Outdoor'; // Category Name

$collection = $_categoryFactory->create()->getCollection()->addFieldToFilter('name', ['in' => $categoryTitle]);

if ($collection->getSize()) {
    $categoryId = $collection->getFirstItem()->getId();
}

我在拼贴画的帮助下得到了它

$this->_objectManager->get('Magento\Catalog\Model\CategoryFactory')->create()->getCollection()
        ->addFieldToSelect('name')
        ->addFieldToFilter('name', ['in' => $categoryTitle]);

:)因为集合只会返回您想要的记录，所以您可以->getFirstItem()在上面的代码中获取唯一的结果

为了在正常运行的脚本中重构它，我建议使用以下命令

$obj = $bootstrap->getObjectManager();
$_categoryFactory = $obj->get('Magento\Catalog\Model\CategoryFactory');
$collection = $_categoryFactory->create()->getCollection()->addAttributeToFilter('title',$categoryTitle)->setPageSize(1);

if ($collection->getSize()) {
    $categoryId = $collection->getFirstItem()->getCategoryId();
}

编辑： 我制作并测试了一个脚本。我在/scripts/file.php中创建了一个文件

<?php
use Magento\Framework\App\Bootstrap;
require __DIR__ . '/../app/bootstrap.php';

$bootstrap = Bootstrap::create(BP, $_SERVER);

$obj = $bootstrap->getObjectManager();

// Set the state (not sure if this is neccessary)
$obj = $bootstrap->getObjectManager();
$_categoryFactory = $obj->get('Magento\Catalog\Model\CategoryFactory');
$categoryTitle = 'Test';
$collection = $_categoryFactory->create()->getCollection()->addAttributeToFilter('name',$categoryTitle)->setPageSize(1);
if ($collection->getSize()) {
    $categoryId = $collection->getFirstItem()->getId();
    echo $categoryId; 
}

我设法编写了自己的（更有效的）方法：

$entityTypeId = \Magento\Catalog\Setup\CategorySetup::CATEGORY_ENTITY_TYPE_ID;
$row = $this->queryF("SELECT * FROM `eav_attribute` WHERE `entity_type_id` = $entityTypeId AND `attribute_code` = 'name'", 1);
$nameAttributeId = $row['attribute_id'];
$categoryNames = $this->queryF("SELECT * FROM `catalog_category_entity_varchar` WHERE `attribute_id` = '$nameAttributeId'");
$this->categoryNameIdMap = [];
foreach ($categoryNames as $item) {
    $id = $item['entity_id'];
    $title = $item['value'];
    $this->categoryNameIdMap[$title] = $id;
}

此代码将所有title：ids缓存到一个数组中，并且仅查询2次。

为我工作。更容易使用！

首先，您需要注入收集工厂类

public function __construct(
    ...
    \Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $collecionFactory ) {
    $this->_collectionFactory = $collecionFactory;
    parent::__construct(...); }

之后，您可以在方法中执行此操作，

$categoryTitle = 'Men';
$collection = $this->_categoryCollectionFactory->create()->addAttributeToFilter('name',$categoryTitle)->setPageSize(1);

if ($collection->getSize()) {
    $categoryId = $collection->getFirstItem()->getId();
}
