Opdatere poster i database
Hej!Jeg er ved at lave et register over videofilm. Jeg er i gang med at opbygge det i Dreamweawer. Alt virker egentlig udemærket. Jeg mangler bare at lave en side, hvor man kan opdatere posterne.
Jeg har lavet en side med et søgefelt, hvor man indtaster den titel man ønsker at finde. Den hopper nu videre til en side, der viser de titler der matcher søgeordet. Man kan så klikke på titlerne og få vist detaljer.
Det jeg mangler er en knap ud for hver, hvor man får mulighed at rette recorden.
Jeg har lavet en side, der skal vise recorden i nogle text-felter. Problemet er bare hvordan jeg får sendt dataene fra siden med visning at titel, og over til den hvor man kan opdatere recorden.
Siden med visning at titler ser således ud:
