Making form fields required

I have a simple form that a user fills out. When they click Submit, aspmailer.asp parses the form and then e-mails the results to my client. I need to make some of the fields on the form, such as name and e-mail, required fields. If they aren't completed, they can't send the form.

I've tried using a javascript solution to pop up an alert if the field is not filled out, but it doesn't work. I'm thinking that ASP and javascript can't coexist peacefully in the same html file?

I have samples of what I'm working on available. Any help you can give me in making the fields required will be greatly appreciated.

BTW, I'm very, very new to programming. I know there is a simple solution to this, but I don't know what it is yet.

it can be done in javascript. i'm not as familiar with that, but it can also be done with asp, by having field validation done before email is sent.

example:
If Request.Form("mandatory_field") = "" Then
sError = "You must fill in this field."
End If
If sError = "" Then
sendEmail
Else
redisplayForm (sError)
End If


And display the error message above the field, or at the top of the form.

Where would I put this? In the html file or the asp file?

'Validate all of the fields
txtValidateError = &quot;&quot;

'check field one - and you can get pretty fancy here!
if request(&quot;fieldone&quot;) = &quot;&quot; then
txtValidateError = &quot;You must fill in Field One<BR>&quot;
end if

'check field two - same goes for this. You can even
'see if the @ sign is in the string. There are some
'routines to check if the e-mail address is valid too!
if instr(request(&quot;fieldtwo&quot;), &quot;@&quot;) <> true then
txtValidateError = txtValidateError & &quot;This e-mail
address appears invalid.<BR>&quot;
end if

'now check to see if error is blank
'if not, set the session(error) and return them to page
'if it is blank, then go ahead and e-mail the info
if txtValidateError <> &quot;&quot; Then
session(&quot;txtValidateError&quot;) = txtValidateError
response.redirect(&quot;formpageaddress&quot;)
'be sure to start your formpageaddress with
'<center><%=session(&quot;txtValidateError&quot;)%></Center>
'and then make the next line clear that error
'session(&quot;txtValidateError&quot;) = &quot;&quot;
else
....complete your code for mailing info
end if
%>

It is a good idea to set each of the values as
session(&quot;variable&quot;)
so you can fill the form back in for your &quot;visitor&quot; when you send them back if there is an error. I'll post more if you don't understand that. =====================

Hey Dennis, thanks for the code! This seems to be what I need. I'm not sure what to put in this code though:

response.redirect(&quot;<center><%=session(&quot;txtValidateError&quot;)%></Center>&quot;)
'be sure to start your formpageaddress with
'<center><%=session(&quot;txtValidateError&quot;)%></Center>
'and then make the next line clear that error
'session(&quot;txtValidateError&quot;) = &quot;&quot;

Also, in the response.redirect, the %> (just before the center tag) is appearing as if it's the end of the script, which is preventing the rest of the script from executing. How can I fix that?

When I try to submit the code, it's telling me that the page cannot be displayed. Here is the entire code. I really think the problem is the <% and %> in the response.redirect code. It renders the rest of the page as text, not code.

'check field two - the address

txtValidateError = &quot;Please type in your address, city, state and ZIP code<BR>&quot;

The javascript validation script that pgferro gave me works and the aspmailer.asp file is doing what it's supposed to. The form is now working just the way I want it to. Thank you for all your help!
