Automatically Submit Form to Post Author

Just in case anyone's interested in this, I've figured out how to have a form automatically submit to the author of the post the page appears on.

<?php
 $author_email_addy = get_the_author_meta( 'user_email' );
 gravity_form(
3,
$display_title=false,
$display_description=true,
$display_inactive=false,
$field_values = array(
'author_email'=> $author_email_addy
),
$ajax=true
 ); ?>

The3 is the ID of the form, FYI, and I'm doing this all via a function call, not using the shortcode / WP Post Editor.

Note the 'author_email'=> $author_email_addy, this is the important part.

1. Add an Email field (from the Advanced Fields in the Form Editor) to your form.
2. Editing that field, click the Advanced tab
3. Click Allow Field to be Populated Dynamically, and enter author_email as the value.
4. Save the form and go to Notifications
5. Scroll down and tick the box Notification to Users
6. In the Send To: field, choose the Email field from step 1 above

That's it!
