Javascript in form & security stopped working

Hi ShadowWizard,

First off, thanks very much for posting the above bits has really helped me

The only thing that is happening I have some simple javascript form clears on each form item that do not work anymore, and also some captcha code which stopped working.

The word document is being picked up to the server, attached and sent to email, however because i have everything in the same page I'm guessing this has something to do with the javascript and captcha not working.

Wonder if you might be able to shed any light on the prob or suggest asny solutions, i think it could be something to do with

Code:

  <form action="<%=Request.ServerVariables( "Script_Name" )%>?action=1" enctype="multipart/form-data" method="POST">

which is forcing the javascript not to work

Thanks

most JavaScript form related code is triggered in the onsumit event of the form.

to make it work again, add the code in bold to the form tag:

Code:

 <form action="<%=Request.ServerVariables( "Script_Name" )%>?action=1" enctype="multipart/form-data" method="POST" onsubmit="return ValidateForm(this);">

replace "ValidateForm" with the real function that used to work, if you don't know
its name post your "old" code that used to work and I'll try to see for myself.

Hi m8,

Thanks for the reply,

I have the validation working, the problem is the ASP captcha

there is a part at the top of the page:

Code:

<script language=vbscript runat=server>
Sub HDWCaptchaValidation
If (Request.QueryString("hdwtest") = "captchainstalled") Then 
  Response.Write "Captcha verification code installed." 
  Response.End 
End If
If (UCase(Request.ServerVariables("REQUEST_METHOD")) = "POST") OR (Request.QueryString.Count >= 4) Then
    Dim SessionCAPTCHA, CheckCAPTCHA, HDWCaptchaBack, HDWname
	SessionCAPTCHA = Trim(CStr(Session("HDWCAPTCHA")))
	Session("CAPTCHA") = ""
	HDWCaptchaBack = Request.Form("hdwfail")	
	If (HDWCaptchaBack = "") Then HDWCaptchaBack = Request.QueryString("hdwfail")
    For Each HDWname in Request.QueryString
        Response.Cookies("hdw" & HDWname) = Request.QueryString(HDWname)
    Next
    For Each HDWname in Request.Form
        Response.Cookies("hdw" & HDWname) = Request.Form(HDWname)
    Next
    For Each HDWname in Request.Cookies
        On Error Resume Next
        If (Left(HDWname,3) = "hdw") AND (Request.QueryString(Right(HDWname,Len(HDWname)-3)) = "") AND (Request.Form(Right(HDWname,Len(HDWname)-3)) = "") Then
             If (Err.Description = "") Then Response.Cookies(HDWname) = ""
        End If   
    Next	
	If (Len(SessionCAPTCHA) < 1) OR ((Request.Form("hdcaptcha") = "") AND (Request.QueryString("hdcaptcha") = "")) OR ((SessionCAPTCHA <> CStr(Request.Form("hdcaptcha"))) AND (SessionCAPTCHA <> CStr(Request.QueryString("hdcaptcha")))) Then 
     Response.Redirect HDWCaptchaBack
     Response.End
 End If
 For Each HDWname in Request.Cookies
     If (Left(HDWname,3) = "hdw") Then
         Response.Cookies(HDWname) = ""
     End If
 Next
End If
End Sub
</script>
<% HDWCaptchaValidation %>

and a hidden value for when it fails:

Code:

<input type="hidden" name="hdwfail" id="hdwfail" value="contact_us.asp?hdwmsg=invalid" />

I Have tried using objUpload("") and the relevant variable where ever there is a request.form however there is one place and one only by the looks of it where it won't handle it.

(taken from above)

Code:

 For Each HDWname in Request.Form
        Response.Cookies("hdw" & HDWname) = Request.Form(HDWname)
    Next

(and changed with objUpload in BOLD is where the problem lies)

Code:

 For Each HDWname in objUpload()
        Response.Cookies("hdw" & HDWname) = objUpload(HDWname)
   Next

I'm unsure whether this is the solution or not it just seemed the most obvious?

The Captcha is a DW extension, when added to the page the page closes now the upload code is included. i'm thinking theres a conflict somewhere but again unsure

never seen such complicated code for such simple task as writing
bunch of cookies.... as far as I could see it's pretty meaningless.

you can achieve what you need without such code, post your
CAPTCHA code itself and I'll try to fix it so it will work with the upload.

Hi Shadowizard,

Hows it going?

Did you managed to intergrate the captcha into your code at all?
