Cookies & Forms

[The Wizzard]

Hi, what i need to do is create a form for users to send information to me, but once they have submitted this form, they cannot submit the form again.

Thanks!

I dont think you need to use a cookie, javascript should be able to handle it

<script language='javascript'>
var submitted=0;
function validateForm()
{
if (submitted==0)
{
document.testForm.submit();
submitted=1;
}
}
</script>

Ya, but i dont want them to be able to re-submit EVER again... What this is, is an enlistment form for a game, and people will be able to send in there info and hope to be recruited, but i dont want someone spamming there info, or just crap info.

Thanks

If you are wanting to set a cookie than if they delete cookies than they can submit the form. You can set a field into your db by capturing their IP or email. On your form page do something like:

for cookie:
whatever page the form action is sent to on the bottom put:

Response.Cookie("frmSubmitted") = "True"

on the top of your form page:

If Response.Cookie("frmSubmitted") = "True" Then
Response.Redirect "default.asp"
End If

Doing it like this they will always be redirected if their cookie is set. Using a db would be the same concept.

Either of those ideas have pros and cons:

Cookies:
Pros-

• Fast
• Efficent

Cons-

• If cookies are disabled, doesn't work.
• IE6 have issues taking unsigned cookies
• They can just be deleted

Database:
Pros-

• Solves the problems cookies have
• Much harder for people to resubmit

Cons-

• Uses up server bandwidth and resources
• If the person is on dial-up they're IP address resets when they re-connect.

I just thought I'd point that out. Perhaps some combination of the two?
