Use data from page 1 field on page 2

I've got a 2 page form in which I would like to display some of the data from page 1 on page 2. I understand how to hook into the form to customise the display on the second page but I don't know how to get at the values of the fields from the first page.

gform_post_paging only gives me the form array which doesn't seem to contain the values. Do any of the other form submission hooks/filters fire between pages? If not, is there a function or global I can access to get at the field values? Or, as a last resort, do I have to dip into the $_POST array?

Any pointers appreciated.

Hi, tamlyn,

You can use the gform_pre_render hook (http://www.gravityhelp.com/documentation/page/Gform_pre_render) along with pulling the information out of $_POST.

Below is an example:

add_filter("gform_pre_render", "populate_welcome");
function populate_welcome($form)
{
	//only get data form form id 31
	if ($form["id"] == 31)
	{
		//check what page you are on
		$current_page = GFFormDisplay::get_current_page($form["id"]);
		if ($current_page == 2)
		{
			//set the field on page 2 to the first/last name from page 1
			//get the name
			$first = rgpost("input_1_3"); //first name field when using the normal name format broken into two fields
			$last = rgpost("input_1_6"); //last name field when using the normal name format broken into two fields
			foreach($form["fields"] as &$field)
			{
				//html field (id 3) on second page which will display name from first page
				if ($field["id"] == 3)
				{
					$field["content"] = "Welcome, " . $first . " " . $last;
				}
			}
		}
	}
	//return altered form so changes are displayed
	return $form;
}

Let me know if you have questions.
