I have created a multi select attribute and assigned this to attribute set. Attribute is showing in product search results but I am unable to include this into product collection filtering as well as into addAttributeToSelct Here is the section I am using this attribute to filter the prodcut collection.

$collection = Mage::getModel("catalog/product")
            ->addFieldToFilter('speciality', array('eq' => $speciality));
echo $collection->getSelect();

And in my browser I have the following result for select query

SELECT `e`.`entity_id`, `e`.`type_id`, `e`.`attribute_set_id`, `e`.`sku`, `e`.`name` FROM `catalog_product_flat_3` AS `e` WHERE (e.status = 1)

Here are screen shot for the attribute configuration enter image description here enter image description here

At first look, I see two points that could help you :

1) It seems that you are using the flat_catalog feature. And, as your attribute speciality is set to be Used in product listing, you have to reindex product_flat index before to be able to retrieve it in your collection.

2) I think you should use addAttributeToFilter instead of addFieldToFilter too.

  • Thanks @julien-loizelet, I was using flat_catalog on my store so by re-indexing the problem was solved. Commented Mar 19, 2018 at 16:29
