I'm having problems getting something to work that really doesn't appear it should be so hard to do.... it's driving me crazy!

I'm trying to make my site PCI Compliant. Well, that is changing it to connect to a page that is hosted on my gateway that is PCI Compliant for the user to input their credit card information.

The gateway needs for me to send the parameters as "HIDDEN" fields using a "POST".  Here is the sample they provided:

[html]
[head]
[ le]XYZ Corporation -- Sample Checkout Page[/ le]
[/head]
[body]
[form name="Form_01" method="POST" action="https://test1.XYZ.com/main.aspx"]
Transaction Amount:[br]
[input type="TEXT" name="TransactionAmount" value="1.00"]
[input type="HIDDEN" name="ECOMRequestID" value="{00000000-0000-0000-0000-000000000000}"]
[input type="HIDDEN" name="PurchaseIdentifier1" value="ORDER-0001"]
[input type="HIDDEN" name="PurchaseIdentifier2" value="123456789"]
[input type="submit" value="Go to Payment Page"]
[/form]
[/body]
[/html]



I created the following code.... It works but only if the "Supports Partial Rendering" is turned off for the module.


Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSubmit.Click

Dim FormHTML As StringBuilder = New StringBuilder
Dim HTML As StringBuilder = New StringBuilder

HTML.Append("[script type=""text/javascript""]")
HTML.Append("var newWin = window.open("""", ""NewWin"", ""width=675,height=600,scrollbars=1,resizable=1"");")
HTML.Append(ControlChars.CrLf)
HTML.Append("newWin.document.open();")
HTML.Append(ControlChars.CrLf)
HTML.Append("newWin.document.write('")

FormHTML.Append("[html][head][ le]Test[/ le][/head][body]")
FormHTML.Append("[form name=""AutoForm"" method=""post"" action=""https://test1.xxxxx.com/xxxxx/main.aspx""]")
FormHTML.Append("[input type=""hidden"" name=""TransactionAmount"" value=""1.00"" \/]")
FormHTML.Append("[input type=""hidden"" name=""ECOMRequestID"" value=""{xxxxx-xxx-xxxx-xxxx-xxxxxxxxxxxx}"" \/]")
FormHTML.Append("[input type=""hidden"" name=""PurchaseIdentifier1"" value=""ORDER-0006"" \/]")
FormHTML.Append("[input type=""hidden"" name=""PurchaseIdentifier2"" value=""Customer #6"" \/]")

FormHTML.Append("[\/form]")
FormHTML.Append("[SCRIPT type=""text/javascript""]document.AutoForm.submit();[\/SCRIPT]")
FormHTML.Append("[\/body][\/html]")

HTML.Append(FormHTML.ToString)
HTML.Append("');")
HTML.Append(ControlChars.CrLf)
HTML.Append("newWin.document.close();")
HTML.Append(ControlChars.CrLf)
HTML.Append("[/SCRIPT]")

Response.Write(HTML.ToString)

End Sub



I have asked a few others and they have said that "best option for you is to render your script to the client within your module.  Add a click handler in the javascript, that executes the script."  I'm really not sure how to do this.


I found this article on CodeProject (http://www.codeproject.com/KB/aspne...ost.aspx). This appears to be a nice solution, however, when the "page.Controls.Add(new LiteralControl(strForm))" line is run, I get an error: "The Controls collection cannot be modified because the control contains code blocks (i.e. [% ... %])."

I'm guessing that I'm making this harder than it really should be..... Thanks for any help!

I'm really not having much luck getting this to work.

The gateway requires that I "POST" the form to them passing the "HIDDEN" fields. I've done a lot of searching and trying things out, but just can't seem to get it to work. It can't be that hard to do.

Can some one help me ?

I deleted my two replies which, frankly, made no sense.  I'll try to take a better look at this.

Thanks for looking into it for me Joe.

The important thing is that it's got to "POST" a form with hidden fields and redirect to the gateway's page.  The DNN page already has a form and I can't seem to get a second form added outside the page's main form.  I tried replacing the form's action with a new action and it almost works, but because the page also has additional hidden fields the gateway get's an error.

Here's what I've gotten working, but I'm not sure if it's the "best" method to do this.

Private Sub PostToETS()
    Dim FormHTML As StringBuilder = New StringBuilder
    Dim HTML As StringBuilder = New StringBuilder

    FormHTML.Append("[html>< le>Test")
    FormHTML.Append("[form name=""AutoForm"" method=""post"" action=""https://test1.xxxxxxx.com/ecomh/main.aspx"">")
    FormHTML.Append("[input type=""hidden"" name=""TransactionAmount"" value=""1.00"" />")
    FormHTML.Append("[input type=""hidden"" name=""RequestID"" value=""{xxxxxxx-xxxx-xxxx-xxxx-xxxxx}"" />")
    FormHTML.Append("[input type=""hidden"" name=""PurchaseIdentifier1"" value=""ORDER-0006"" />")
    FormHTML.Append("[input type=""hidden"" name=""PurchaseIdentifier2"" value=""Customer #6"" />")

    FormHTML.Append("[/form>")
    FormHTML.Append("[SCRIPT type=""text/javascript"">document.AutoForm.submit();")
    FormHTML.Append("[\/body><\/html>")

    HTML.Append(FormHTML.ToString)

    Response.Write(HTML.ToString)
End Sub

While I haven't had a lot of time to dig into this, the short answer is that you can use some javascript (or jQuery) to do the Post. If you google "javascript post" or something similar, you'll find a lot of helpful information. Basically, you want to use an onclick property to call the javascript to emulate the post.
