Hey Robert, its pretty much the same as everything else, WooCommerce uses custom taxonomies for categories and tags so you just need to use taxonomy fields to display those.

If you have other attributes, then these will be post meta – however these do not work the same as taxonomies or categories for example, they require a bit more setting up.

First you’ll need to find the meta key that is used for the values you want to search, so for example if I wanted to add a field for price, then I would add a post meta field to my search form UI, and then I would choose _price as the meta key. Depending on how you want to display it you might choose a range slider, so I would choose the number type and the range slider.

If you’re not sure what the meta key is for the attribute you want to search, then I think the easiest way of figuring that out is to do a dump of your post meta. You could add the following in your loop in one of your templates to get a list of all meta keys / values for a specific post or a page of posts:

<?php 
$post_meta = get_post_meta( get_the_ID() );
echo '<pre>';
var_dump($post_meta);
echo '</pre>';
?>

Does that make sense?

Hi Ross,

I’m a newbie and trying to use the search-form on adapted woocommerce products. I’ve added about 20 new product attributes but I can’t find their meta-key identifier in the post-meta building block. Their is a huge list of meta-keys but the ones I defined aren’t there. How can I find those new product-attribute meta-keys?

Thx
