Get value of selected multiselect attribute

Question

Take the following "car" product: Volkswagen Golf.

It has a multiselect attribute car_options with the following possible options and their ids:

• Airco (id=123) selected
• Radio (id=124) selected
• Bluetooth (id=125)
• Navigation (id=126)

Radio and Airco are selected for this product. How can I get those two values (radio, airco) and display them? $_product is given.

Answer 1

Try this:

echo $_product->getResource()->getAttribute('car_options')->getFrontend()->getValue($_product);

Answer 2

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $product = $objectManager->get('Magento\Catalog\Model\Product')->load($product_id);

$attributevalues= $product->getResource()->getAttributeRawValue($product_id,'my_custom_attribute_code',$storeid);

it works.. Hope it help you..

Answer 3

The following code

1. returns the value ids of the selected options for this product: 123,124
2. turns that into an array: array(123,124)
3. then finds the label of those options: 123=>Airco and 124=>Radio
4. and returns the values in a text string: Airco, Radio

$_attribute_code = 'car_options';
$car_options_csv = Mage::getResourceModel('catalog/product')->getAttributeRawValue($productId, $_attribute_code, $storeId); // returns: 123,124
$car_options = explode(',', $car_options_csv);
$attributeId = Mage::getResourceModel('eav/entity_attribute')->getIdByCode('catalog_product',$_attribute_code);
$attribute = Mage::getModel('catalog/resource_eav_attribute')->load($attributeId);
$attributeOptions = $attribute ->getSource()->getAllOptions();

$res = '';
foreach($attributeOptions as $a)
{
    $l = $a['label'];
    $m = $a['value'];
    if (strlen(trim($l))>0 && in_array($m, $car_options))
    {
        $res .= trim($l) . ', ';
    }
}
echo substr($res, 0, -2);;

Answer 4

Thanks @Mayers, his solution is too good not to override the native getAttributeText:

 public function getAttributeText($attributeCode)  
 {
    return $this->getResource()
        ->getAttribute($attributeCode)
        ->getFrontend()
        ->getValue($this);
 }

and to add to the customer model as well.
