check om alle felter i en form er udfyldt..
Hejsa,Jeg er ved at lave en signup side til squirrelmail, og har klippet klistret i diverse script. Alt virker nu, det eneste jeg mangler er at chekke om der er indtastet i alle 3 felter (navn, brugernavn, password)
Jeg har søgt på nettet og fundet masser af måder at gøre det på, men aner ikke hvor jeg skal sætte det ind i koden. Kan nogen hjælpe mig ?!
Koden her:
