Get category data by using category id in Magento 2

Create the block file in your module.

<?php
namespace Magemonkey\Category\Block;
 
class Category extends \Magento\Framework\View\Element\Template
{
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Api\CategoryRepositoryInterface $categoryRepository,
        array $data = []
    ) {
        $this->categoryRepository = $categoryRepository;
        parent::__construct($context, $data);
    }
 
    /* $categoryId as category id */
    public function getCategoryById($categoryId){
        try {
            return $category = $this->categoryRepository->get($categoryId);
        } catch (\Magento\Framework\Exception\NoSuchEntityException $e) {
            return ['response' => 'Category Not Found'];
        }
    }
}
?>

<?php

namespace Magemonkey\Category\Block;

class Category extends \Magento\Framework\View\Element\Template

{

public function __construct(

\Magento\Framework\View\Element\Template\Context $context,

\Magento\Catalog\Api\CategoryRepositoryInterface $categoryRepository,

array $data = []

) {

$this->categoryRepository = $categoryRepository;

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

}

/* $categoryId as category id */

public function getCategoryById($categoryId){

try {

return $category = $this->categoryRepository->get($categoryId);

} catch (\Magento\Framework\Exception\NoSuchEntityException $e) {

return ['response' => 'Category Not Found'];

}

Put this code in your template file and pass the category id in getCategoryById function.

<?php  
$categoryId = 10; // category id
$getCategory = $block->getCategoryById($categoryId);
echo $getCategory->getName();echo "<br>";
echo $getCategory->getUrlKey();echo "<br>";
echo $getCategory->getIsActive();echo "<br>";
echo "<pre>";print_r($getCategory->getData()); ?>

<?php

$categoryId = 10; // category id

$getCategory = $block->getCategoryById($categoryId);

echo $getCategory->getName();echo "<br>";

echo $getCategory->getUrlKey();echo "<br>";

echo $getCategory->getIsActive();echo "<br>";

echo "<pre>";print_r($getCategory->getData()); ?>
