I have a form imbedded in my WordPress site using the form plugin CFormsII.
Currently, on submitting the form, the data is emailed to myself via PHP Mail and added to a MySQL db.
I would like a "processing" page to be created in PHP, so that the form can be submitted to the processing page, which will do the following:
Email data to myself
Add an entry into a MySQL db
HTTP Post the data to a third party URL
Redirect the user to a success page
