I've created a new product attribute 'brand'. This attribute is within my default attribute set. Now I'm trying to get all brands from a product collection within a category.

I'm fetching the product collection:

$products = $this->_productCollectionFactory

But the brand is not displayed? The attribute brand is just a simpel text attribute. How can I fetch all brands from this collection?


  • did you rebuild the indexes? If you have flat catalog enabled, did you mark the attribute as "used in product listing"? – Marius Feb 29 '16 at 15:58
  • Marius, thanks a lot. The option 'Used in product listing' was the fix! – Silvan Feb 29 '16 at 17:10

Based on the comments...
when using an attribute in a product collection, if the flat catalog is enabled, the attribute must be marked as Used in product listing in order to be picked up by the collection.

  • What if flat catalog isn't enabled? – Steve Robbins May 17 '17 at 21:27
  • @SteveRobbins with flat catalog disabled it should work with out any additional actions. – Marius May 18 '17 at 6:01
  • Update for 2019: Flat Catalog is considered a performance drag. It should be disabled. – seanbreeden Dec 11 '19 at 17:35
  • Hello @Marius, I have disabled Flat Catalog, And in my custom collection I want few attributes like: $collection->addAttributeToSelect(['special_discount', 'special_discount_value', 'special_offer']);. But this is not working. Once I enabled Flat Catalog it's working. How can I achieve this with Flat Catalog disabled value. Can you please suggest. – Ravi Soni Feb 25 '20 at 10:01
  • with flat catalog disabled it should work as you do it. I have no idea why it doesn't – Marius Feb 25 '20 at 11:11
