Jeg har et problem med noget php kode, som jeg simpelthen ikke kan få til at virke...
Koden udtrækker to tilfældige tal mellem 1 & 10 og lægger dem herefter sammen. Brugeren skal så lave det samme regnestykke og hvis resultatet er ens og brugeren trykker på en submit-knap så skal brugeren logges ind på en anden side.
Det er i bund og grund en CAPTCHA jeg forsøger at lave !
Her er koden:
