s php som amater a mam jeden problem. Mam takyto formular:
Spravnost udajov kontrolujem javascriptom. Ale ak sa chce zaregistrovat niekto a zada uz existujuce meno tak to kontrolujem cez php + mysql. Ak zadane meno uz existuje vypise echo nejake hlasenie.
Ako dosiahnem aby sa to hlasenie vypisalo takto?
Predpokladam ze to bude len nejaka podmienka pre DIV-om ktory chcem vypisat ale zatial mi nic nefungovalo. Za ochotu a pomoc vopred velmi pekne dakujem.
Pripajam aj zdrojovy kod:
