HTML markup in attribute values

As I recall, the attributes are saved complete with any html. Check in wp_postmeta to confirm. But later, when you get use WooCommerce functions to fetch the attribute data, it will be filtered, and I couldn’t find a way to prevent that, so what worked was to fetch the attributes directly from the database with get_post_meta().

@lorro no, when you set up a global attribute you cannot use any html in the term value’s name – when you save it, the html gets stripped immediately. And when you try to enter an , nothing is saved at all. As an alternative, is there a way to display the value’s desription instead of the value’s name in my mentioned code? Because allowing html in the value description is easy.

I’ve checked and yes you’re right, global attributes are not saved with any html. The original post was about custom attributes and they can be saved with html.

I don’t think attrubutes have descriptions, but terms do. So your code will need to cycle through the attributes, and foreach attribute, get the terms. Then cycle through the terms and get the description from each term.

Probably best to stay away from WooCommerce functions because they will lead down a route that isn’t right for what you want to do.

Sorry, not tested.

@lorro Attribute VALUES can have descriptions. When you set up an attribute value, for example “green”, there is an optional field for the description. But I don’t know how to change my code to display this description instead of the value’s name. Something like

$attributes_data[] = $attribute_name . ': ' . $term_description;

does not work.

An attribute value is called a term, so you’d use get_the_terms() to get an array of term objects for a given attribute, then cycle through the terms and use
$term->description to get the description.
