mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\AppServ\www\wishlist\admlist.php on line 39 & 64 & 89
Jeg har brug for lidt hjælp. Jeg er ved at lave min årsopgave i programmering og jeg laver en hjemmeside. Jeg har noget kode her og den kommer ud med ovenstående fejl men jeg kan ikke finde fejlen, alt ser ud til at være i orden og listen den finder eksisterer. Hvis i kan hjælpe må i gerne skrive det som svar så jeg kan give point bag efter.<html>
