I am trying to submit a form form from an ascx control which is the user control of a module I have created in my dnn 6.1.3 web site on my local machine. The module compiles ok and the form appears just fine when i add the module to any page in my dnn site.

The form works fine stand alone and is just a submit to an external .asp page.

Can anyone tell me how to achieve this form submission. I also have some javascript validation to run before the actual submission.

Please help, I've been on this for over 5 days and maybe i'm blind to the answer. Have searched high and low......

You cant put forms inside a dnn module - the asp.net page cycle contains a single master form which prevents any other forms from being added directly to a page.

You have three options:

1. Place the form on is own HTML page and load that page using an IFRAME module --  QUICK and easy

2. Use Javascript to make the physical POST to the remote web site on the client side - most elegant option if you are up to the javascript code.

3. Use the HttpWebRequest asp.net object on the server side to make the physical POST call to the remote web site.

This page here should get you started on the 2 and 3

The javascript option is ok.

I managed to embed the javascript and can get the post action to work ok. Now I have to add the multiple elements to myForm from my form, pardon the pun.

function postdata()
{
   var fieldValue = document.getElementById("field1").value;
   postwith("http://someothersite.com",{field1:fieldValue});
}

function postwith (to,p) {
  var myForm = document.createElement("form");
  myForm.method="post" ;
  myForm.action = to ;
  for (var k in p) {
    var myInput = document.createElement("input") ;
    myInput.setAttribute("name", k) ;
    myInput.setAttribute("value", p[k]);
    myForm.appendChild(myInput) ;
  }
  document.body.appendChild(myForm) ;
  myForm.submit() ;
  document.body.removeChild(myForm) ;
}

I understand most of this except a few items:

In the call to postwith
postwith("http://someothersite.com",{field1:fieldValue})
How would i include multiple field:value pairs?

and lastly for now....how would i get the value of a select element?

getting there......
