html post form different destinations
You can't. There is no way to send a form to two ressources.
What you CAN do is send a HTTP request in your register script to the newsletter script, e.g. using urllib2.
I am developing a django web app in which I would like to have a registration process. In this  registration process I have of course a form asking for name, email and password. What I would like to do is, send the form via post to 2 different places. One of which is of course the registration database which saves the password and the like, and the other being the Emencia newsletter app. In the case it helps, Emencia only needs email and a name (optional).
So how can I do this with only one form, 2 places to send it to and, taking just some of the data of the form and not all?
Thank you!
