In this post I am going to explain how to get sub categories of specific 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\n        \r\npublic function __construct(\r\n\t\\Magento\\Backend\\Block\\Template\\Context $context,        \r\n\t\\Magento\\Catalog\\Model\\CategoryFactory $categoryFactory,\r\n\tarray $data = []\r\n)\r\n{\r\n\t$this->_categoryFactory = $categoryFactory;        \r\n\tparent::__construct($context, $data);\r\n}\r\n\r\n\/* Get category object *\/\r\npublic function getCategory($categoryId)\r\n{\r\n\t$category = $this->_categoryFactory->create()->load($categoryId);\r\n\treturn $category;\r\n}\r\n\r\n\/* Get all children categories IDs *\/\r\npublic function getAllChildren($asArray = false, $categoryId)\r\n{\r\n\treturn $this->getCategory($categoryId)->getAllChildren($asArray);\r\n}\r\n\r\n\/* Get children ids comma separated *\/\r\npublic function getChildren($categoryId)\r\n{\r\n\treturn $this->getCategory($categoryId)->getChildren();\r\n}<\/pre>\n
Add below code snippet in template file.<\/p>\n
$categoryId = 10;\r\n \r\n\/\/ Load category by category ID\r\n$category = $block->getCategory($categoryId);\r\n\r\necho \"<pre>\";\r\nprint_r($category->getData());\r\necho \"<\/pre>\";\r\n\r\n\/\/ Get comma-separated children category ids\r\n$childrenCategoryIds = $block->getChildren($categoryId);\r\n\r\necho $childrenCategoryIds;\r\n\r\n\/\/Get all children category ids as an array\r\n$allChildrenCategoryIdsArr = $block->getAllChildren(true, $categoryId);\r\n\r\necho \"<pre>\";\r\nprint_r($allChildrenCategoryIdsArr);\r\necho \"<\/pre>\";\r\n\r\n\/\/Get all children category ids ids comma-separated\r\n$allChildrenCategoryIds = $block->getAllChildren(false, $categoryId);\r\n\r\necho $allChildrenCategoryIds;<\/pre>\n
 <\/p>\n
2. Using Object Manager<\/strong><\/p>\n
$objectManager =  \\Magento\\Framework\\App\\ObjectManager::getInstance();        \r\n\r\n$categoryFactory = $objectManager->get('\\Magento\\Catalog\\Model\\CategoryFactory');\r\n \r\n$categoryId = 10;\r\n\r\n\/\/ Load category by category ID\r\n$category = $categoryFactory->create()->load($categoryId);\r\n\r\necho \"<pre>\";\r\nprint_r($category->getData());\r\necho \"<\/pre>\";\r\n\r\n\/\/ Get comma-separated children category ids\r\n$childrenCategoryIds = $category->getChildren($categoryId);\r\n\r\necho $childrenCategoryIds;\r\n\r\n\/\/Get all children category ids as an array\r\n$allChildrenCategoryIdsArr = $category->getAllChildren(true);\r\n\r\necho \"<pre>\";\r\nprint_r($allChildrenCategoryIdsArr);\r\necho \"<\/pre>\";\r\n\r\n\/\/Get all children category ids ids comma-separated\r\n$allChildrenCategoryIds = $category->getAllChildren(false);\r\n\r\necho $allChildrenCategoryIds;<\/pre>\n
