Magento: How to upload file


Attribute in Magento is like a property. All Products, Categories, Orders, Customers, etc. have attributes. For example, the attribute of a product is its name, sku, description, image, etc.

This article will show you how to get attribute name and value for any product.


The following code is about getting attribute collection and then fetching that attribute’s name, value, type, and other parameters.

Note: The attribute code in the case below 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:-

Note: I suppose the attribute code to be ‘my_attribute‘

$attributeValue = Mage::getModel('catalog/product')
                            ->load($_product->getId())
                            ->getAttributeText('my_attribute');
Load any particular attribute by attribute code

Here is the code to get data of any particular attribute by the attribute code.

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

// echo "<pre>"; print_r($attributeInfo->getData()); echo "</pre>";
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 = $attributeInfo->getSource()->getAllOptions(false);
// echo "<pre>"; print_r($attributeOptions); echo "</pre>";
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 "<pre>"; print_r($attributeOptionSingle); echo "</pre>";
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);
Hope this helps. Thanks.
