WC_Data_Store_WP::update_or_delete_post_meta( WC_Data $object, string $meta_key, mixed $meta_value )
Update meta data in, or delete it from, the database.
Description Description
Avoids storing meta when it’s either an empty string or empty array. Other empty values such as numeric 0 and null should still be stored. Data-stores can force meta to exist using must_exist_meta_keys.
Note: WordPress get_metadata function returns an empty string when meta data does not exist.
Parameters Parameters

-
(Required) The WP_Data object (WC_Coupon for coupons, etc).
- $meta_key
-
(Required) Meta key to update.
- $meta_value
-
(Required) Value to save.
Return Return
(bool) True if updated/deleted.
