Hi Alex,
In a multiple select those values are stored in array. That array is you
pers[].
In $HTTP_POST_VARS this will appear as this array, i.e. pers()
To list the values in the multiple select do this:
while(list($key,$value) = each(pers)) {
echo("$key -> $value");
}
or instead of echo you can assign those values newly or store them in a
database for example.
all the values look something like this in the array
pers[0] = 1. multiple select
pers[1] = 2. multiple select
pers[2] = 3. multiple select
pers[3] = 4. multiple select
regards, Jens
