}

all things you will use to retrieve value product custom option cart order in Magento 2: https://www.mageplaza.com/how-get-value-product-custom-option-cart-order-magento-2.html

You can get attribute value by following way

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

First we must ensure that the desired attribute is loaded, and then output it. Use this:

$product = Mage::getModel('catalog/product')->load('<product_id>', array('<attribute_code>'));
$attributeValue = $product->getResource()->getAttribute('<attribute_code>')->getFrontend()->getValue($product);

A way that I know of:

$product->getResource()->getAttribute($attribute_code)
        ->getFrontend()->getValue($product)

This one works-

echo $_product->getData('ATTRIBUTE_NAME_HERE');

Try this

 $attribute = $_product->getResource()->getAttribute('custom_attribute_code');
    if ($attribute)
    {
        echo $attribute_value = $attribute ->getFrontend()->getValue($_product);
    }

Please see Daniel Kocherga's answer, as it'll work for you in most cases.

In addition to that method to get the attribute's value, you may sometimes want to get the label of a select or multiselect. In that case, I have created this method which I store in a helper class:

/**
 * @param int $entityId
 * @param int|string|array $attribute atrribute's ids or codes
 * @param null|int|Mage_Core_Model_Store $store
 *
 * @return bool|null|string
 * @throws Mage_Core_Exception
 */
public function getAttributeRawLabel($entityId, $attribute, $store=null) {
    if (!$store) {
        $store = Mage::app()->getStore();
    }

    $value = (string)Mage::getResourceModel('catalog/product')->getAttributeRawValue($entityId, $attribute, $store);
    if (!empty($value)) {
        return Mage::getModel('catalog/product')->getResource()->getAttribute($attribute)->getSource()->getOptionText($value);
    }

    return null;
}

It seems impossible to get value without loading product model. If you take a look at file app/code/core/Mage/Eav/Model/Entity/Attribute/Frontend/Abstract.php you'll see the method

public function getValue(Varien_Object $object)
{
    $value = $object->getData($this->getAttribute()->getAttributeCode());
    if (in_array($this->getConfigField('input'), array('select','boolean'))) {
        $valueOption = $this->getOption($value);
        if (!$valueOption) {
            $opt = new Mage_Eav_Model_Entity_Attribute_Source_Boolean();
            if ($options = $opt->getAllOptions()) {
                foreach ($options as $option) {
                    if ($option['value'] == $value) {
                        $valueOption = $option['label'];
                    }
                }
            }
        }
        $value = $valueOption;
    }
    elseif ($this->getConfigField('input')=='multiselect') {
        $value = $this->getOption($value);
        if (is_array($value)) {
            $value = implode(', ', $value);
        }
    }
    return $value;
}

As you can see this method requires loaded object to get data from it (3rd line).

If you have an text/textarea attribute named my_attr you can get it by: product->getMyAttr();

You don't have to load the whole product. Magentos collections are very powerful and smart.

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('entity_id', $product->getId());
$collection->addAttributeToSelect('manufacturer');
$product = $collection->getFirstItem();
$manufacturer = $product->getAttributeText('manufacturer');

At the moment you call getFirstItem() the query will be executed and the result product is very minimal:

[status] => 1
[entity_id] => 38901
[type_id] => configurable
[attribute_set_id] => 9
[manufacturer] => 492
[manufacturer_value] => JETTE
[is_salable] => 1
[stock_item (Varien_Object)] => Array
    (
        [is_in_stock] => 1
    )

You could write a method that would do it directly via sql I suppose.

Would look something like this:

Variables:

$store_id = 1;
$product_id = 1234;
$attribute_code = 'manufacturer';

Query:

SELECT value FROM eav_attribute_option_value WHERE option_id IN (
    SELECT option_id FROM eav_attribute_option WHERE FIND_IN_SET(
        option_id, 
        (SELECT value FROM catalog_product_entity_varchar WHERE
            entity_id = '$product_id' AND 
            attribute_id = (SELECT attribute_id FROM eav_attribute WHERE
                attribute_code='$attribute_code')
        )
    ) > 0) AND
    store_id='$store_id';

You would have to get the value from the correct table based on the attribute's backend_type (field in eav_attribute) though so it takes at least 1 additional query.

you can use

<?php echo $product->getAttributeText('attr_id')  ?>
