title: Passing Params to Wufoo iframe
body: <p>Ok so there are tons of examples on how to pass custom parameters hidden fields in Wufoo forms (in my case the current URL of the form). The problem is these all deal with the javascript embed code. I'm working with a company whos custom backend won't allow the js embed and therefore I must use the iframe embed method. I cannot for the life of me figure out how to do this. There are a couple frustratingly close examples that mention using PHP successfully but never show the actual implementation. Can anyone tell me how to do this or point me in the right direction? <br>Relevant info: </p>
  
  <p>I currenlty have a field that is hidden using css. I want that field to be populated with the url or some part of the url it could be www.host.com/thepage or just /thepage as long as we can see where on the site the user submitted the form
