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.Since version 3, WooCommerce generates a
featured
term (name and slug) located inwp_terms
table, which custom taxonomy isproduct_visibility
inwp_term_taxonomy
table.The
wp_term_relationships
table make the link between:object_id
keyproduct_visibility
taxonomy throughterm_taxonomy_id
keyThe
wp_term_taxonomy
table make the link with the termfeatured
through itsterm_id
key.It works jut like a post term.
