However, I would also like to pre-populate/autofill some values (the subject and message body, to be specific) in the new post. Here's what's going on. There is a feedback link in a web app that we're using, and I am able to pull certain values from the page (such as the url, page title, etc.). I would like to be able to organize feedback posts in our JForum based on the page title and URL. If nothing else, I would like this information to be in the message body of the post so that it is apparent which page the user is commenting on.
Is there a way to structure the request URL so that fields are pre-populated/autofilled? ...some other way of accomplishing this?
First, if you're allowing anonymous posting in the forum this form is posting to, you probably can create your own custom form who's action is the jForum insert a new topic action. Just look at the source of a new topic form to get the fields needed (especially the hidden fields).
