Witam jak w temacie
Posiadam 2 tabele, kategorie i ogloszenia

kategorie to:
-id
parent_id
-link

ogloszenia to
-id
-cat
-title
-display

problem jest tego typu że jak wyświetlam ogłoszenia z display = 1 to ok ale jak pojawiają się równirż ogłoszenia z display = 0 ... czy ktoś mógłby mi pomóc żeby nie pojawiało się display = 0 ?
