I need to be able to get the Category name and ID from a product and I am able to retrieve the ID doing the following:

$categoryID = $product->getCategoryCollection()->getFirstItem()->getId();

However If I try to get the name, It always returns null.

$categoryName = $product->getCategoryCollection()->getFirstItem()->getName();

How do I get the name?

I have tried loading the Category by ID but that seems to be returning null as well, I have checked in the admin screen the correct ID for the category is returned.

try it like this:

$product->getCategoryCollection()
    ->addAttributeToSelect('name')
    ->getFirstItem()
    ->getName();

Normally, this should work:

$categoryID = $product->getCategoryCollection()->getFirstItem()->getId();
$category = Mage::getModel('catalog/category')->load($categoryID);
$categoryName = $category->getName();

If it doesn't (as you write), I can't imagine why. However, have you tried this?

$categoryName = $product->getCategoryCollection()->addAttributeToSelect('name')->getFirstItem()->getName();

  • Thanks for the reply but still returns null. Seems weird I can get the ID but not the name Commented Apr 13, 2016 at 22:40
  • If the category exists, at least the load()-method should return something. And $product->getCategoryCollection()->count() is > 0? Can you add the output of $product->getCategoryCollection()->addAttributeToSelect()->getFirstItem()->debug() to your question? Commented Apr 14, 2016 at 7:17
