Integrating with WordPress: Registering a new user from form submission on Unbounce

Hi,

I was hoping you might have a clever idea of how to do the following:

I want to use Unbounce landing pages to offer a free trial to a WordPress membership site. The ideal funnel would be:

1. Land on landing page
2. Click button to open lightbox
3. Submit email address
4. email address gets passed to wordpress
5. wordpress registers a new user using email address as username and automatically generates a password
6. wordpress sends email to user

So steps 1, 2 and 3 are pretty simple (thanks to Unbouce and this thread https://getsatisfaction.com/unbounce/…).

Step 6 WordPress will do.

Any idea how to do steps 4 and 5? I know I can use query strings to pass the user email address…

This article lays out some php code to register the user:

But bringing it all together… ?

I realize this may not be strictly an Unbouce question. But it is kind of an Unbounce / WordPress integration question… 🙂

Thanks for the help!!
