MySQL join - bestilling af resultater via en anden tabel PHP

Du skal bruge en simpel JOIN

SELECT a.item_name, a.dish_id, b.sort
    FROM item_names AS a 
    JOIN link_extras AS b 
      ON a.dish_id = b.dish_id
   WHERE menu_id = 1
    AND section_id = 2
       GROUP BY b.dish_id
ORDER BY b.sort
