# Adding a Gravity Form form submission page
# Author: Hans Swolfs
# Website: https://hansswolfs.be
# Version: 1.0
# Let's rock & roll

# add the filter to create the review page.
# the default filter is gform_review_page. 
# You can specify the form you want to apply this filter for by adding the ID of the form in the end; e.g. gform_review_page_2
# Mostly you want to do this or else you'll get a review page for every form on the site.
# The code used in this tutorial is the actual code used on the link provided in the blog post on https://hansswolfs.be/hoe-maak-je-een-samenvattingspagina-in-gravity-forms

add_filter( 'gform_review_page_2', 'hs_add_review_page', 10, 5 );

# A filter is followed by the function that needs to be executed

function hs_add_review_page( $review_page, $form, $entry ) {

	# Enable the review page

	$review_page['is_enabled'] = true;

  # First thing to do is put the form's fields in variables for easier handling afterwards
  # So far I haven't found a loop to handle this but my PHP skills don't go that far
  # Tip also is to give the variables a clear name. I chose for this set up:
  # f = field, cp/d1/d2 the different sections on the form and then the field identifier
  # the :1.3, :3, ... are the field shortcodes. You can get them by entering the needed fields on a GF form's confirmation page.
	# On the first page of the form, general data is collected about the person filling in the application.
	# Depending on how many persons they choose, the next page is formed and there the application's names and other details are filled in.
