Deleting records
We have similar methods for deleting records in each of the existing tables as we have for updating records. The following list illustrates a few of the built-in delete functions:
| delete_post_meta | This deletes custom fields using the specified key in the wp_postmeta table. Accepts post ID, key, and value as parameters. |
| wp_delete_post | This removes existing posts, pages, or attachments from the wp_posts table. Accepts post ID as parameter. |
| delete_user_meta | This removes the metadata matching criteria from a user from the wp_usermeta table. Accepts user ID, key, and value as parameters. |
