beskytte filer
Jeg har nogle sider der er beskyttede med kodeord, men jeg har også en opload funktion. Er det muligt at beskytte de filer jeg oploader, så man kun kan se dem hvis man er logged ind?
Så vidt jeg kan se, erstatter det mit oprindelige loginsystem. Er det muligt at integrere de to, så man har adgang til filerne, når man har logget ind på mine phpsider? Eller er dette system mere sikkert.
Så lyder det jo lige som noget for mig :) Holder det også spambots ude? Vil det være en god ide at kombinere det med mit gamle php/mysql-system, eller er det ikke nødvendigt?
Du kan eventuelt manipulerer din .htacces fil med en klasse som denne i forbindelse med et brugersystem:
