How to get attribute name and value in Magento

Here is the code to get attribute code and value for any product
Let as assume the attribute code is "my_attribute"

/**
 * get attribute collection
 */
$attribute = $_product->getResource()->getAttribute('my_attribute');
/**
 * get attribute type
 */
$attribute->getAttributeType();
/**
 * get attribute Label
 */
$attribute->getFrontendLabel();
/**
 * get attribute default value
 */
$attribute->getDefaultValue();
/**
 * check if the attribute is visible
 */
$attribute->getIsVisible();
/**
 * check if the attribute is required
 */
$attribute->getIsRequired();
/**
 * get attribute value
 */
$attributeValue = Mage::getModel('catalog/product')->load($_product->getId())->getMyAttribute();

Here is the code to fetch value from a select box attribute

$attributeValue = Mage::getModel('catalog/product')
                            ->load($_product->getId())
                            ->getAttributeText('my_attribute');

Load any particular attribute by attribute code

$attributeInfo = Mage::getResourceModel('eav/entity_attribute_collection')
                        ->setCodeFilter(YOUR_ATTRIBUTE_CODE)
                        ->getFirstItem();
 
// echo "
"; print_r($attributeInfo->getData()); echo "
";

Get all option value list for the particular attribute

You can see above that I got attribute information by attribute code. My attribute information is stored as $attributeInfo.

Here is the code to get all option values for my attribute $attributeInfo.

$attributeOptions = $attributeInfo->getSource()->getAllOptions(false);
// echo "
"; print_r($attributeOptions); echo "
";

Get attribute’s option information by option id

I have my attribute as $attributeInfo.
I have my attribute’s option value array as $attributeOptions.

Suppose, I want to get detail information of any option listed in $attributeOptions array. Here is the code to do so

$attributeId = $attributeInfo->getAttributeId();
$optionId = YOUR_ATTRIBUTE_OPTION_ID;
 
$attributeOptionSingle = Mage::getResourceModel('eav/entity_attribute_option_collection')
                                    ->setPositionOrder('asc')
                                    ->setAttributeFilter($attributeId)
                                    ->setIdFilter($optionId)
                                    ->setStoreFilter()
                                    ->load()
                                    ->getFirstItem();
 
// echo "
"; print_r($attributeOptionSingle); echo "
";

Get attribute of particular entity type

Here, I am going to get information about ‘order_id’ attribute of ‘invoice’ entity type.

$entityType = Mage::getModel('eav/config')->getEntityType('invoice');
$entityTypeId = $entityType->getEntityTypeId();
 
$attribute = Mage::getResourceModel('eav/entity_attribute_collection')
                ->setCodeFilter('order_id')
                ->setEntityTypeFilter($entityTypeId)
                ->getFirstItem();

Get attribute options of Configurable product

$confAttributes = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray($_product);
