Sometimes, you need to get a precise information about a product, and it’s very boring to load it.

Two methods are possible :

Collection method

$productId = 25; // Your product ID
$model = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect('attribute_code')
->addAttributeToFilter('entity_id',$productId)
->getFirstItem();

$attribute_value = $model->getAttributeCode();

We retrieve one result with the “getFirstItem” method, and get the attribute value thanks to “addAttributeToSelect” method

AttributeRawValue Method

With a single line of code, you can get the attribute value of your product :

$productId = 25;
$attribute_value = Mage::getResourceModel('catalog/product')->getAttributeRawValue($productId, 'attribute_code');

You can add a third parameter which is the storeId or the store object itself.

$productId = 25;
$attribute_value = Mage::getResourceModel('catalog/product')->getAttributeRawValue($productId, 'attribute_code', 1);

If I want many values?

If you want many values, in the collection method, you have to put an array in your addAttributeToSelect :

$model = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect(array('attribute_code','attribute_code_bis'))
->addAttributeToFilter('entity_id',$productId)
->getFirstItem();

$attribute_value = $model->getAttributeCode();
$attribute_value_bis = $model->getAttributeCodeBis();

And with AttributeRawValue method, you need one line per attribute :

$rc = Mage::getResourceModel('catalog/product');
$attribute_value = $rc->getAttributeRawValue($productId, 'attribute_code'); 
$attribute_value_bis = $rc->getAttributeRawValue($productId, 'attribute_code_bis');

Which is the best?

Performances between the two methods are close, and better than a load. If you method will be called many times, “getAttributeRawValue” is better. If it will be called only one time during the page load, prefer “getCollection”.

Retrieve attribute’s label

When my attribute is a select, how to retrieve the real value ?

With the 2 methods above, you will have the “value_id” of the value. But you can need to have the label of this attribute value :

// Not loading the product, just creating one simple instance
$product = Mage::getModel('catalog/product')
->setStoreId($store_id) // Set a store ID to define the language, 0 for Admin
->setAttributeCode($attribute_value); // Respect Camel case for your setter
$attribute_label= $product->getAttributeText('attribute_code');

If you already have a product instance :

// Not loading the product, just creating one simple instance
$attribute_label = $product
->setStoreId($store_id) // Set a store ID to define the language, 0 for Admin
->setAttributeCode($attribute_value) // Respect Camel case for your setter
->getAttributeText('attribute_code');

Retrieve attribute option label in SQL (with store_id)

Here you can find a little function with 2 parameters : the id of the value and the store id (optional).
You can put it on a helper for example.

public function getAttributeOptionValue($optionId, $storeId = 0){
        $db = Mage::getSingleton('core/resource')->getConnection('core_read');
        $query = 'SELECT value FROM eav_attribute_option_value WHERE (store_id = '.$storeId.' OR store_id = 0) AND option_id = '.$optionId.' ORDER BY store_id DESC LIMIT 0,1';
        try{
            $row = $db->fetchRow($query);
        } catch(Exception $e){
            return false;
        }

        if(empty($row)  || !isset($row['value'])){
            return false;
        }

        return $row['value'];
    }
