How to check if attribute exist in product attribute set?
I need to know if a product has an attribute for its set of attributes.
I get the attribute with:
$attrPricekg = Mage::getModel('catalog/product')->load($_product->getId())->getPricekg();
If attribut exist in product attribute set, $attrPricekg display: set value for the product or 0 if no value set for the product.
If the attribute does not exist in product attribute set, $attrPricekg display 0. This is my problem.. I need to avoid this, I want to check that the attribute does not exist for that product.
Thanks.

now I'll provide an answer which works regardless!
$product = Mage::getModel('catalog/product')->load(16);
$eavConfig = Mage::getModel('eav/config');
/* @var $eavConfig Mage_Eav_Model_Config */
$attributes = $eavConfig->getEntityAttributeCodes(
Mage_Catalog_Model_Product::ENTITY,
$product
);
if (in_array('pricekg',$attributes)) {
// your logic
}
To check if a specific attribute exists in product, it should return true even if the attribute has the value 'null'.
One way that works is:
$attr = Mage::getModel('catalog/resource_eav_attribute')->loadByCode('catalog_product',$code);
if (null!==$attr->getId())
{ //attribute exists code here }
It can also of course be written in one line:
if(null!===Mage::getModel('catalog/resource_eav_attribute')->loadByCode('catalog_product','attributecode_to_look_for')->getId()) {
//'attributecode_to_look_for' exists code here
}
Found it and modified a bit on: https://github.com/astorm/Pulsestorm/issues/3
May be this way is better for you:
$attribute = Mage::getModel('catalog/product')->load($productId)->getResource()->getAttribute($attributeCode);
if ($attribute && $attribute->getId()) { ... }
Also you may try
$attributes = $product->getAttributes();
But you may check all in attribute collection:
$entityTypeId = Mage::getModel('eav/entity')
->setType('catalog_product')
->getTypeId();
$attributeId = 5;
$attributeSetName = 'Default';
$attributeSetId = Mage::getModel('eav/entity_attribute')
->getCollection()
->addFieldToFilter('entity_type_id', $entityTypeId)
->addFieldToFilter('attribute_set_name', $attributeSetName)
->addFieldToFilter('attribute_id', $attributeId)
->getFirstItem();
May be source code need some corrections, but I think you will understand the idea.
