Magento 2 - The right way to get a product attribute value

Question

I'm wondering if there's a right way to get the value of a product attribute, in a generic way.

EDIT: Or whatever I can use to get the info from a dropdown or text field using the same mechanism

I know I can do: $product->getData('attribute_code')

But if the code it's a dropdown select then I'll be getting a value which doesn't represent really what the users selected. For example in a dropdown to select a t-shirt size options would be (s,l,xl) and internal values (1,2,3)

It's a way to know how to get the attribute type to later identify what I should be looking for or the right way to pick the value.

Answer 1

for dropdown use this code

<?php echo $attr = $_product->getResource()->getAttribute('your_attribute_code')->getFrontend()->getValue($_product); // dropdown attribute"?>

the other code only displays the ID from the database tabel when used for dropdown. this is why you get 1,2,3

Answer 2

Actually magento internally use magic method so if your attribute code is tshirt_size then magic method would be getTshirtSize()

if you want to get a text of tshirt_size attribute then you can use the below method which is return selected size (i.e. l)

$product->getAttributeText('tshirt_size');

if you want that value of tshirt_size then you can use the below method.

$product->getTshirtSize();
