Get Attribute model by attribute_code in Magento

How could I get Attribute model (from: eav_attribute table) by attribute_co开发者_如何学Cde in Magento?

Notice:

- I don't care what is entity_type.

Thank you so much.

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

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

$attribute_code = "flat_printing_quantity"; 
$attribute_details =
Mage::getSingleton("eav/config")->getAttribute(Mage_Catalog_Model_Product::ENTITY, $attribute_code);
$attribute = $attribute_details->getData();
echo $attribute['attribute_id'];

$attributeModel = Mage::getModel('eav/entity_attribute')->loadByCode(1, 'is_approved'); echo $attributeModel->getAttributeId();
