Product Categories Archives

In this post I am going to explain how to get all categories of specific product in magento 2. 1. Using Dependency Injection Add below code snippet in Block class.

protected $_categoryCollectionFactory;
protected $_productRepository;

public function __construct(
	\Magento\Catalog\Block\Product\Context $context, 
	\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $categoryCollectionFactory,
	\Magento\Catalog\Model\ProductRepository $productRepository,
	array $data = []
) {
	$this->_categoryCollectionFactory = $categoryCollectionFactory;
	$this->_productRepository = $productRepository;
	parent::__construct($context, $data);
}

public function getProductCategoryIds($productId) {
	$product = $this->_productRepository->getById($productId);
	$productCategoryIds = $product->getCategoryIds();
	return $productCategoryIds;
}

public function getProductCategoriesCollection($categoryIds) {
	$categoryCollection = $this->_categoryCollectionFactory->create();
	$categoryCollection->addAttributeToSelect('*');
	$categoryCollection->addIsActiveFilter();
	$categoryCollection->addAttributeToFilter('entity_id', $categoryIds);
	return $categoryCollection;
}

protected $_categoryCollectionFactory;

protected $_productRepository;

public function __construct(

\Magento\Catalog\Block\Product\Context $context,

\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $categoryCollectionFactory,

\Magento\Catalog\Model\ProductRepository $productRepository,

array $data = []

) {

$this->_categoryCollectionFactory = $categoryCollectionFactory;

$this->_productRepository = $productRepository;

parent::__construct($context, $data);

}

public function getProductCategoryIds($productId) {

$product = $this->_productRepository->getById($productId);

$productCategoryIds = $product->getCategoryIds();

return $productCategoryIds;

}

public function getProductCategoriesCollection($categoryIds) {

$categoryCollection = $this->_categoryCollectionFactory->create();

$categoryCollection->addAttributeToSelect('*');

$categoryCollection->addIsActiveFilter();

$categoryCollection->addAttributeToFilter('entity_id', $categoryIds);

return $categoryCollection;

}

Add below code snippet in template file.

$productId = 1;

// get product categorory ids
$productCategoryIds = $block->getProductCategoryIds($productId);

echo "<pre>";
print_r($productCategoryIds);
echo "</pre>";


// get product category collection
$categoryCollection = $block->getProductCategoriesCollection($productCategoryIds);

if ($categoryCollection && count($categoryCollection) > 0) {
    foreach ($categoryCollection as $category) {
        echo $category->getId() . '<br>';
        echo $category->getName() . '<br>';
        echo $category->getUrl() . '<br>';
    }
}

$productId = 1;

// get product categorory ids

$productCategoryIds = $block->getProductCategoryIds($productId);

echo "<pre>";

print_r($productCategoryIds);

echo "</pre>";

// get product category collection

$categoryCollection = $block->getProductCategoriesCollection($productCategoryIds);

if ($categoryCollection && count($categoryCollection) > 0) {

foreach ($categoryCollection as $category) {

echo $category->getId() . ' ';

echo $category->getName() . ' ';

echo $category->getUrl() . ' ';

}

2. Using Object Manager

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

$productRepository = $objectManager->get('\Magento\Catalog\Model\ProductRepository');
$categoryCollection = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');

$productId = 1;

$product = $productRepository->getById($productId);

// get product categorory ids
$productCategoryIds = $product->getCategoryIds();

echo "<pre>";
print_r($productCategoryIds);
echo "</pre>";


// get product category collection
$categoryCollection = $categoryCollection->create();
$categoryCollection->addAttributeToSelect('*');
$categoryCollection->addAttributeToFilter('entity_id', $productCategoryIds);

if ($categoryCollection && count($categoryCollection) > 0) {
    foreach ($categoryCollection as $category) {
        echo $category->getId() . '<br>';
        echo $category->getName() . '<br>';
        echo $category->getUrl() . '<br>';
    }
}

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

$productRepository = $objectManager->get('\Magento\Catalog\Model\ProductRepository');

$categoryCollection = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');

$productId = 1;

$product = $productRepository->getById($productId);

// get product categorory ids

$productCategoryIds = $product->getCategoryIds();

echo "<pre>";

print_r($productCategoryIds);

echo "</pre>";

// get product category collection

$categoryCollection = $categoryCollection->create();

$categoryCollection->addAttributeToSelect('*');

$categoryCollection->addAttributeToFilter('entity_id', $productCategoryIds);

if ($categoryCollection && count($categoryCollection) > 0) {

foreach ($categoryCollection as $category) {

echo $category->getId() . ' ';

echo $category->getName() . ' ';

echo $category->getUrl() . ' ';

}
