In this post I am going to explain how to get product collection by category in magento 2.<\/p>\n

1. Using Dependency Injection<\/strong><\/p>\n

Add below code snippet in Block class.<\/p>\n

protected $_categoryFactory;\r\nprotected $_productCollectionFactory;\r\n\t\r\npublic function __construct(\r\n\t\\Magento\\Backend\\Block\\Template\\Context $context,        \r\n\t\\Magento\\Catalog\\Model\\CategoryFactory $categoryFactory,\r\n\t\\Magento\\Catalog\\Model\\ResourceModel\\Product\\CollectionFactory $productCollectionFactory,\r\n\tarray $data = []\r\n)\r\n{    \r\n\t$this->_categoryFactory = $categoryFactory;\r\n\t$this->_productCollectionFactory = $productCollectionFactory;\r\n\tparent::__construct($context, $data);\r\n}\r\n\r\n\/* Get category object *\/\r\npublic function getCategory($categoryId)\r\n{\r\n\t$category = $this->_categoryFactory->create();\r\n\t$category->load($categoryId);\r\n\treturn $category;\r\n}\r\n\r\n\/* Product collection by category id *\/\r\npublic function getCategoryProductCollection($categoryId)\r\n{\r\n\t$productCollection = $this->getCategory($categoryId)->getProductCollection();\r\n\t$productCollection->addAttributeToSelect('*');\r\n\t$productCollection->addAttributeToFilter('visibility', \\Magento\\Catalog\\Model\\Product\\Visibility::VISIBILITY_BOTH);\r\n\t$productCollection->addAttributeToFilter('status',\\Magento\\Catalog\\Model\\Product\\Attribute\\Source\\Status::STATUS_ENABLED);\r\n\treturn $productCollection;\r\n}\r\n\r\n\/* Filtering a product collection by multiple category ids *\/\r\npublic function getProductCollectionByCategories($categoryIds) {\r\n\t$productCollection = array();\r\n\tif ($categoryIds && count($categoryIds) > 0) {\r\n\t\t$productCollection = $this->_productCollectionFactory->create();\r\n\t\t$productCollection->addAttributeToSelect('*');\r\n\t\t$productCollection->addCategoriesFilter(['in' => $categoryIds]);\r\n\t\t$productCollection->addAttributeToFilter('visibility', \\Magento\\Catalog\\Model\\Product\\Visibility::VISIBILITY_BOTH);\r\n\t\t$productCollection->addAttributeToFilter('status', \\Magento\\Catalog\\Model\\Product\\Attribute\\Source\\Status::STATUS_ENABLED);\r\n\t}\r\n\treturn $productCollection;\r\n}<\/pre>\n
 <\/p>\n
Add below code snippet in template file.<\/p>\n
$categoryId = 3;\r\n\r\n$categoryProductCollection = $block->getCategoryProductCollection($categoryId);\r\n\r\necho \"<pre>\";\r\nprint_r($categoryProductCollection->getData());\r\necho \"<\/pre>\";\r\n\r\nif ($categoryProductCollection && count($categoryProductCollection) > 0) {\r\n    foreach ($categoryProductCollection as $product) {\r\n        echo $product->getId() . \"<br \/>\";\r\n        echo $product->getName() . \"<br \/>\";\r\n        echo $product->getProductUrl() . \"<br \/>\";\r\n    }\r\n}\r\n\r\n\/\/Category ids array\r\n$categoryIds = [7, 8, 9];\r\n\r\n$productCollectionByCategories = $block->getProductCollectionByCategories($categoryIds);\r\n\r\necho \"<pre>\";\r\nprint_r($productCollectionByCategories->getData());\r\necho \"<\/pre>\";\r\n\r\nif ($productCollectionByCategories && count($productCollectionByCategories) > 0) {\r\n    foreach ($productCollectionByCategories as $product) {\r\n        echo $product->getId() . \"<br \/>\";\r\n        echo $product->getName() . \"<br \/>\";\r\n        echo $product->getProductUrl() . \"<br \/>\";\r\n    }\r\n}<\/pre>\n
 <\/p>\n
2. Using Object Manager<\/strong><\/p>\n
$objectManager = \\Magento\\Framework\\App\\ObjectManager::getInstance();\r\n\r\n$categoryId = 3;\r\n\r\n$categoryFactory = $objectManager->get('\\Magento\\Catalog\\Model\\CategoryFactory');\r\n\r\n\/\/ Get category object\r\n$category = $categoryFactory->create()->load($categoryId);\r\n\r\n\/\/ Product collection by category id\r\n$categoryProductCollection = $category->getProductCollection();\r\n$categoryProductCollection->addAttributeToSelect('*');\r\n$categoryProductCollection->addAttributeToFilter('visibility', \\Magento\\Catalog\\Model\\Product\\Visibility::VISIBILITY_BOTH);\r\n$categoryProductCollection->addAttributeToFilter('status', \\Magento\\Catalog\\Model\\Product\\Attribute\\Source\\Status::STATUS_ENABLED);\r\n\r\necho \"<pre>\";\r\nprint_r($categoryProductCollection->getData());\r\necho \"<\/pre>\";\r\n\r\nif ($categoryProductCollection && count($categoryProductCollection) > 0) {\r\n    foreach ($categoryProductCollection as $product) {\r\n        echo $product->getId() . \"<br \/>\";\r\n        echo $product->getName() . \"<br \/>\";\r\n        echo $product->getProductUrl() . \"<br \/>\";\r\n    }\r\n}\r\n\r\n\r\n$productCollectionFactory = $objectManager->get('\\Magento\\Catalog\\Model\\ResourceModel\\Product\\CollectionFactory');\r\n\r\n\/\/Category ids array\r\n$categoryIds = [7, 8, 9];\r\n\r\n\/\/ Filtering a product collection by multiple category ids\r\n$productCollectionByCategories = $productCollectionFactory->create();\r\n$productCollectionByCategories->addAttributeToSelect('*');\r\n$productCollectionByCategories->addCategoriesFilter(['in' => $categoryIds]);\r\n$productCollectionByCategories->addAttributeToFilter('visibility', \\Magento\\Catalog\\Model\\Product\\Visibility::VISIBILITY_BOTH);\r\n$productCollectionByCategories->addAttributeToFilter('status', \\Magento\\Catalog\\Model\\Product\\Attribute\\Source\\Status::STATUS_ENABLED);\r\n\r\necho \"<pre>\";\r\nprint_r($productCollectionByCategories->getData());\r\necho \"<\/pre>\";\r\n\r\nif ($productCollectionByCategories && count($productCollectionByCategories) > 0) {\r\n    foreach ($productCollectionByCategories as $product) {\r\n        echo $product->getId() . \"<br \/>\";\r\n        echo $product->getName() . \"<br \/>\";\r\n        echo $product->getProductUrl() . \"<br \/>\";\r\n    }\r\n}<\/pre>\n
