What I'd like to do is provide "edit" links alongside the various sections of the form data so the user can jump to the page containing those fields.
Does anyone know how I can do this or, failing that, can anyone at least throw me a bone and tell me how Webform decides which page to display after a "next/previous" button is pressed on a multipage form?
click() on the Previous button, but to no avail; it still goes back to the previous (second to last) page. There is a
$_POST['details']['page_num'] containing the current page number, but it's apparently not used to determine where the Next and Previous buttons take the form.
