Get parent name of current category on category list pages in Magento 2

Question

I have found several methods of obtaining the product id of a category while on a category list page, but none covering the best way to obtain the parent name of the category while on a category page. Any help is appreciated.

Answer 1

I found this to be the quicker solution to retrieving the parent of the category.

<?php 
   $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
   $category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');//get current category
   echo $category->getParentCategory()->getName();
?>

In Magento2,if you have an instance of category object then you can get its parent category name by calling $categoryObject->getParentCategory->getName().

If you want to show the parent category name on the phtml template of the category page then, in the Block class assigned to the phtml template,you need to inject dependency to initialize magento registry class \Magento\Framework\Registry in the Block class' __construct() and from current_category get the current category object

    protected $_registry;

     /**
      * @param \Magento\Framework\Registry $registry,
     */

        public function __construct(
            ...,
            ...,
            \Magento\Framework\Registry $registry,
            ...
        ) {
            $this->_registry = $registry;
            ...
            ...
        }

/**
 * Return catalog current category object
 * @return \Magento\Catalog\Model\Category
 */

public function getCurrentCategoryOb()
{
    return $this->_registry->registry('current_category');
}

Now at phtml file call this code for getting parent category name:

if($this->getCurrentCategoryOb()):
if($this->getCurrentCategoryOb()->getParentCategory()):
echo  $this->getCurrentCategoryOb()->getParentCategory())->getName();
endif
endif;

Use the following code to resolve your query:

<?php $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
      $current_category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');
      $parent_category = $current_category->getParentCategory();
      echo $current_category->getName();
      echo $parent_category->getName(); ?>
