Hello!!! =D How can I get the specific value of an attribute to create a conditional later in the checkout page, what I want is that depending on the value it shows me some data or others

Thank you very much

Haave a look at

 wc_get_product_terms( $product->id, 'pa_size', array( 'fields' => 'names' ) )

global $product;
$koostis = $product->get_attribute( 'pa_koostis' );
