wpdb delete query count
The $wpdb->query(...) function returns an integer value corresponding to the number of rows affected. So, if you delete 10 rows then it'll return 10, use it like:
$count = $wpdb->query('delete query');Also you may use:
$count = $wpdb->delete( $table, $where, $where_format = null );Returns the same affected rows on successful operation and false on failure. Read more on Codex.
