Please help me.

Answer 1

I think you should get data like this,

$category->getData('attribute_code');

 OR

$category->getAttributeCode();

Answer 2

As this attribute are not magento default attribute and there are not setter and getter method are not defined at the data interface Magento\Catalog\Api\Data\CategoryInterface So, $category->getData('attribute-code'); you cannot get this attribute value.

If you want then you have to use $category->getCustomAttribute($attributeCode)

Like:

    $category = $this->categoryFactory->create();
    $category->load(12);
    $customAttributeValue = $category->getCustomAttribute($attributeCode);
   if(null !== $customAttributeValue){
       $myAttributeValue = $customAttributeValue->getValue();
   }

I do not support or use this type of work.If will be better to use Extension attribute using Service contact class Magento\Catalog\Api\CategoryRepositoryInterface

BUT, Extension attribute is not working for Category entity for the blog https://github.com/magento/magento2/issues/10847,So you can get getCustomAttribute or getCustomAttributes()

Forgetting the data, you can use service contact interface

$storeId = 1;
try{
    /// $this->categoryRepository is instean of Magento\Catalog\Api\CategoryRepositoryInterface
   $category = $this->categoryRepository->get(12, $storeId);
   $customAttributeValue = $category->getCustomAttribute($attributeCode);
   if (null !== $customAttributeValue) {
       $myAttributeValue = $customAttributeValue->getValue();
   }           
} catch (\Magento\Framework\Exception\NoSuchEntityException $ex) {

}

Answer 3

In front, You can get the value of Category attribute by load category object and call the function like below.

$getCategory = CATEGORY_OBJECT;
echo $getCategory->getCustomCategoryField();

Take reference from below link.
