Get Attribute model by attribute_code in Magento

Question

How could I get Attribute model (from: eav_attribute table) by attribute_code in Magento?
Notice:
- I don't care what is entity_type.
Thank you so much.

Answer 1

You have to know entity_type because you can have the same attribute_code for different entities. So to get attribute model:

$attributeModel = Mage::getModel('eav/entity_attribute')->loadByCode($entity_type, $attributeCode);

$entity_type parameter can be numeric (id directly), string (for example 'catalog_product' or Mage_Catalog_Model_Product::ENTITY) or it can be instance of model Mage_Eav_Model_Entity_Type

Answer 2

Perhaps you can read the attributes by filter the collection

   Mage::getModel('eav/entity_attribute')->getCollection()->addFieldToFilter('attribute_code', array('in' => $codes) )

Since I need the attributes from the Product by code, I do it like this:

    $codes = (array) $codes; 
    $res = array_intersect_key($this->getAttributes(), array_flip($codes));

$codes is an attribute_code-array Scope: extended Mage_Catalog_Model_Product
