Login med session virker ikke
Hejsa.Jeg har godt nok lige en masse kode, men håber der er en eller flere som har tid til at kigge det igennem.
Mit problem er at når jeg trykker submit på min login form, så får jeg den samme side igen. Jeg prøvede derfor at tilføje: action="$_SERVER['SCRIPT_NAME']" i min form, men ved ikke om det er rigtigt? Jeg får bare en ny side med at $_SERVER['SCRIPT_NAME'] ikke findes. Men er der nogle som har en ide til hvor jeg skal lede? Jeg har tilføjet en user og kode i min database.
Mvh Mads
