Script per verificare eta

**Hedo** · 06-07-2006, 12:36

MI servirebbe uno script che verificala maggiore eta della persona; avete presente quei form che si mettono davanti a siti di alcolici oppure porno?

Qualcuno sa aiutarmi?

In ASP non ho mai provato (ma non deve essere difficile, penso all'utilizzo di datediff ad esempio)... ma ho sempre usato javascript:

codice:

<HEAD>
<TITLE>agecheck.htm</TITLE>
<SCRIPT LANGUAGE=JAVASCRIPT>
<!--
var pos = document.cookie.indexOf("UnderAge=");
if (pos == false)


    {
    location = "ageok.htm";
}
function y2k(number) { return (number < 1000) ? number + 1900 : number; }


    function isDate(day,month,year) {
    var today = new Date();
    year = ((!year) ? y2k(today.getYear()):year);
    month = ((!month) ? today.getMonth():month-1);
    if (!day) return false
    var test = new Date(year,month,day);
    if ( (y2k(test.getYear()) == year) &&
    (month == test.getMonth()) &&
    (day == test.getDate()) )
    return true;
    else
    return false
}
function getMonthLength(month,year,julianFlag)


    {
    var ml;
    if(month==1 || month==3 || month==5 || month==7 || month==8 || month==10||month==12)


        {ml = 31;}


            else {


                if(month==2) {
                ml = 28;
                if(!(year%4) && (julianFlag==1 || year%100 || !(year%400)))
                ml++;
            }
            else


                {ml = 30;}
            }
            return ml; 
        }
        function CheckAge(form)

oddio che select

VVoVe:

cmq, per controllarlo anche in asp... :master: ... vediamo di scrivere qualcosa:

diciamo che nel form seleziona la data di nascita completa (gg/mm/aaaa)

codice:

<%
dim gg,mm,aaaa,data_tizio
gg=request.form("gg")
mm=request.form("mm")
aaaa=request.form("aaaa")

data_tizio=gg & "/" & mm & "/" aaaa

if not isDate(data_tizio) then response.write "errore nella data":response.end()

data_oggi=now()

if DateDiff("yyyy", data_oggi, data_tizio)>= 18 then
response.write "bravo sei un uomo maturo"
else
response.write "vade retro pischello"
end if
