问题

Woocommerce v2.6 stores the following meta_key values in the wp_postmeta table:

_sku

_price

_regular_price

_sale_price

_manage_stock

_stock_status

_featured

Does Woocommerce v3.x, still store are all of the above in an identical manner as v2.6 or have any of the above been relocated to another table and/or modified in any way?

In WooCommerce 3+ everything listed is the same, except for _featured that doesn't work any more.

The "feature" product functionality in WooCommerce 3+:

Since version 3, WooCommerce generates a featured term (name and slug) located in wp_terms table, which custom taxonomy is product_visibility in wp_term_taxonomy table.

The wp_term_relationships table make the link between:

• the "featured" products IDs through the object_id key
• the ID for product_visibility taxonomy through term_taxonomy_id key

The wp_term_taxonomy table make the link with the term featured through its term_id key.

It works jut like a post term.

Update: regarding other changes not listed in your question.

The product_visibility taxonomy also handle those terms (functionalities):

• exclude-from-search (product visibility option)
• exclude-from-catalog (product visibility option)
• outofstock (stock status)
• rated-1 to rated-5 (product rating)
