How I can get the value of multi select attribute. I tried with below code but all return null

$pro->getCustomAttribute('offer')
$pro->getAttributes('offer');
$pro->getAttributeText('offer')

Answer 1

$pro->getAttributeText(‘offer’)

is the correct method to call. However, you need to make sure that the attribute is joined to your collection.

$collection->addAttributeToSelect(‘offer’)
