Attribute values for product variations

Question

I'm facing a big problem with product variations and their attributes in woocommerce. I'm trying to display a table with each attribute for each availabe product variation. But Woocommerce saves the attributes in post meta complete in lowercase, replaces slashes and german special characters like ü,ö,ä etc. I get the attributes with $variation->get_variation_attributes(). I've searched the database for the save values you can see for example in the dropdown in the admin panel, but they are saved like this without a link to the variation they are assigned to:

a:5:{s:10:"bestell-nr";a:6:{s:4:"name";s:11:"Bestell-Nr.";s:5:"value";s:9:"1 | 2 | and so on...

How can i get the attributes in their correct format to display?

Thanks for your help!

Answer 1

Actually product attributes are actually terms in custom taxonomies, so you just need to get the terms in that particular taxonomy. All attribute taxonomies are prefaced with 'pa_'. So a size attribute would be a 'pa_size' taxonomy. And the variation ID is the post ID for a variation.

But depending on how you want to display it, WooCommerce has a built-in function for displaying all a variation's attributes:

The following will display a definition list of all of a variations attributes.

echo wc_get_formatted_variation( $product->get_variation_attributes() );

And passing a second parameter of true will display a flat list:

echo wc_get_formatted_variation( $product->get_variation_attributes(), true );
