Magento: fetching manufacturer/brand from database - magento

Question

I have this code from Mukesh Chapagain: link here
$_product = Mage::getModel('catalog/product')->load(PRODUCT_ID);
$manufacturerName = $_product->getAttributeText('manufacturer');
$manufacturerId = $_product->getManufacturer();
This seems not to pick up the manufacturers even though I have them as attributes. Is it due to the fact that the manufacturer field is a drop-down?
any help in getting manufacturer attribute will be appreciated

Answer 1

To retrieve all Manufactures
$attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'manufacturer');
foreach ( $attribute->getSource()->getAllOptions(true, true) as $option){
$attributeArray[$option['value']] = $option['label'];
}
foreach($attributeArray as $key=>$val){
echo $val;
}
Get products from Manufactures
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('manufacturer');
$collection->addFieldToFilter(array(
array('attribute' => 'manufacturer', 'eq' =>$designer_id),
));
Get selected manufacturer to products
$_productCollection=$this->getLoadedProductCollection();
foreach ($_productCollection as $_product):
echo $_product->getAttributeText('manufacturer');
endforeach;

Answer 2

Honestly, I cannot tell what is wrong with the code in question.
However I have recently been working on something related - if you're trying to use a collection of products. Rather than trying to fix something which probably isn't broken, think of this as an alternative suggestion.
To start with you would need to download my library of query patterns. It contains a class for drop-down attributes. The following adds a manufacturer_text column to the collection.
$products = Mage::getResourceModel('catalog/product_collection');
Knectar_Select_Product_Values::enhanceProducts($products, 'manufacturer');
foreach ($products as $product) {
echo $product->getManufacturerText(), '<br>';
}

This work for me:
SELECT
CPEI.entity_id,
CPE.sku,
CPEI.attribute_id,
EA.attribute_code,
CPEI.value AS value_id,
EAOV.value
FROM
catalog_product_entity_int AS CPEI
INNER JOIN eav_attribute_option_value AS EAOV ON (EAOV.option_id = CPEI.value AND EAOV.store_id = CPEI.store_id)
INNER JOIN catalog_product_entity AS CPE USING(entity_id)
INNER JOIN eav_attribute_option AS EAO USING(option_id)
INNER JOIN eav_attribute AS EA ON(CPEI.attribute_id = EA.attribute_id)
WHERE
(
CPEI.value IS NOT NULL AND
EA.attribute_code = 'manufacturer' AND
CPEI.store_id = 0
);
