How to get manufacturer name for each product

Question

I have to get some attributes for each product I've gotten most of them but I don't know how to get manufacturer name and the upc or ean barcode value in adminhtml.

I've tried with this code

         $name = 'Manufacturer';
         $attributeInfo = Mage::getResourceModel('eav/entity_attribute_collection')->setCodeFilter($name)->getFirstItem();
         $attributeId = $attributeInfo->getAttributeId(81);
         $attribute = Mage::getModel('catalog/resource_eav_attribute')->load($attributeId);
         $attributeOptions = $attribute ->getSource()->getAllOptions(false);
         var_dump($attribute);

But I can Just print (like in the image) $attribute level and then the $attributeOptions goes empty.

Answer 1

$productId='your_product_id';
$product=Mage::getModel('catalog/product')->load($productId);

$manufaturer=$product->getAttributeText('manufacturer');

Answer 2

$name = 'manufacturer';

    $attributeInfo = Mage::getResourceModel('eav/entity_attribute_collection')->setCodeFilter($name)->getFirstItem();
    $attributeId = $attributeInfo->getAttributeId();
    $attribute = Mage::getModel('catalog/resource_eav_attribute')->load($attributeId);
    $attributeOptions = $attribute ->getSource()->getAllOptions(false);

    foreach ($attributeOptions as $_option){
        echo $_option['label'];

        $productcollection = Mage::getModel('catalog/product')->getCollection()
            ->addAttributeToSelect('*')
            ->addAttributeToFilter($name, $_option['value']);

        foreach ($productcollection as $_product){
            echo $_product->getName();
        }
    }

Answer 3

Try:

<?php $attributes = $_product->getAttributes(); $Manufacturer = $attributes['manufacturer']->getFrontend()->getValue($_product); echo $Manufacturer; ?>
