I need help with my form checking

[unregistered]

Ok. I'm really bad with asp, and i'm wondering if someone could help me make a script that will put a cookie into a person's computer that expires in say, a minute. Now this cookie is planted when he/she submits my form, and the form wont let them submit again until the cookie has expired (1 minute). Its on an emailing form, and i don't want humungo spam from people who just click submit, go back and hit submit again.

Any help would be greatlky appreciated.

Oh! just so you know the page is at http://clix.to/bg2 its also under construction.

why not use clientside javascript to disable the submit button once the form has been sent in ? If you do this along with validation making them fill out the form each time no one will bother trying to reclick. Here is a link for such
http://javascript.internet.com/forms/disable-submit.html

if you want to set a cookie in asp to expire in two seconds then do so like this. (Written in VBScript)
<%
Response.Cookies("foobar").Expires = dateadd("s",2,now)
%>

If you can use asp.net read this

Or a pretty simple solution, just set a session variable once the form is submitted...

Session("submitted") = "1"

Then check to make sure Session("submitted") <> "1" before processing the email... i.e.:

If Session("submitted") <> "1" Then
'Process your email here
Else
'It was already submitted
End If

If you want to do it with a cookie, it's just as easy, too:

Response.Cookies("submitted") = "1"
Response.Cookies("submitted").Expires = DateAdd("s", 60, Now())

Then check to make sure Request.Cookies("submitted") <> "1" before processing the email... i.e.:

If Request.Cookies("submitted") <> "1" Then
'Process your email here
Else
'The cookie was set less than a minute ago
End If

:)

P.S. Oops! Didn't notice you already gave him the DateAdd() solution, Miranda. ;)

P.P.S. I had read some posts about the DateAdd() function not working with cookie expirations, so just to be sure I tested the code above and it works perfectly. Re-reading the posts in question, it's obvious the user was using a variable for one of the DateAdd() parameters which apparently didn't have a value. Go figure. :D
