imam dropdown list i kad stavim u mysql query insert into, nema u bazi podataka niceg, prazno je, dok za username, password, email bude ono sta upisem tijekom registracije ? jednom sam uspio al sad ne znam vise :sa:

pod maincategories i subcategories je to, i to mi nece uci u bazu iako iz dropdown lista odaberem ono sta zelim :S

if(isset($_POST[“reggumb”]))
{
$check = mysqli_query($conn,“SELECT * FROM korisnici WHERE username =’”.$username."’");
$numrows = mysqli_num_rows($check);
if($numrows == 0)
{
$password=($password);
$ins = mysqli_query($conn, “INSERT INTO korisnici (id, username, password, email, date, maincategories, subcategories) VALUES (’’, '”.$username."’ , ‘".$password."’ , ‘".$email."’, ‘".$date."’,’".$maincategories."’,’".$subcategories."’ ) ;");
if($ins)
echo “eeeeee”;
}

}

Sta ti ovo znači?

Prva stvar; ispiši ove varijable $maincategories i $subcategories
Druga stvar; daj html
Treća stvar; di definiraš sve ove varijable za kategorije username i pwd?
