Webform not passing address values to Ubercart

I thought I had figured this out, when I inadvertently broke my working uc_cart_add_item() functions by moving some things into fieldsets. Once I figured out that I needed to add ["fieldset_key"] in between ["submitted_tree"] and ["field_key"] I thought that was going to fix the address-passing, but that didn't solve the problem.

Any other suggestions for things I can troubleshoot? Here's my code, in case it's something stupid that will be really obvious to someone else:

<?php setcookie("customer[first_name]", $form_state["values"]["submitted_tree"]["attendee_information"]["first_name"], time()+2592000, "/");
setcookie("customer[last_name]", $form_state["values"]["submitted_tree"]["attendee_information"]["last_name"], time()+2592000, "/");
setcookie("customer[company]", $form_state["values"]["submitted_tree"]["attendee_information"]["organization"], time()+2592000, "/");
setcookie("customer[street]", $form_state["values"]["submitted_tree"]["attendee_information"]["street_address"], time()+2592000, "/");
setcookie("customer[street2]", $form_state["values"]["submitted_tree"]["attendee_information"]["address_2"], time()+2592000, "/");
setcookie("customer[city]", $form_state["values"]["submitted_tree"]["attendee_information"]["city"], time()+2592000, "/");
setcookie("customer[country]", $form_state["values"]["submitted_tree"]["attendee_information"]["country"], time()+2592000, "/");
setcookie("customer[zipcode]", $form_state["values"]["submitted_tree"]["attendee_information"]["zip_code"], time()+2592000, "/");
setcookie("customer[email]", $form_state["values"]["submitted_tree"]["attendee_information"]["e_mail"], time()+2592000, "/");
setcookie("customer[phone]", $form_state["values"]["submitted_tree"]["attendee_information"]["phone"], time()+259200, "/");
if ($form_state["values"]["submitted_tree"]["attendee_information"]["state"]) {
   setcookie("customer[state]", $form_state["values"]["submitted_tree"]["attendee_information"]["state"], time()+2592000, "/");
}
else if ($form_state["values"]["submitted_tree"]["attendee_information"]["province"]) {
    setcookie("customer[state]", $form_state["values"]["submitted_tree"]["attendee_information"]["province"], time()+2592000, "/");
}
if ($form_state["values"]["submitted_tree"]["conference_fee"]["fee_category"] == "m1") {
    uc_cart_add_item(389, 1);
}
elseif ($form_state["values"]["submitted_tree"]["conference_fee"]["fee_category"] == "m4") {
    uc_cart_add_item(387, 1);
}
elseif ($form_state["values"]["submitted_tree"]["conference_fee"]["fee_category"] == "n4") {
    uc_cart_add_item(386, 1);
}
else {
    uc_cart_add_item(388, 1);
}
if ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "100K") {
    uc_cart_add_item(390, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "250K") {
    uc_cart_add_item(391, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "500K") {
    uc_cart_add_item(392, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "750K") {
    uc_cart_add_item(393, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "1M") {
    uc_cart_add_item(394, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "2M") {
    uc_cart_add_item(395, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "5M") {
    uc_cart_add_item(386, 1);
}
elseif ($form_state["values"]["submitted_tree"]["membership_costs"]["org_budget_size"] == "10M") {
    uc_cart_add_item(397, 1);
} ?>

The bottom two IF statements that add items to the cart are working; it's the top part that's not.

I also tried: removing the country cookie (since I'm not using a country field), and putting an IF statement around address line 2, since it's not a required field. I was thinking that maybe having some cookies in there with no data was causing the whole cookie piece to fail.

Still no love. Any suggestions as to what else I could try? I am really stumped and desperate to get this working.

Thanks for this great module! The uc_cart_add_item piece has been a lifesaver!

Got this working, and I feel very dumb! My problem really was that I didn't have the fieldsets in the submitted tree. But in between the time I originally posted and the time I figured out about the fieldsets, I disabled the ECO customer pane and billing pane options (since there wasn't any billing address filled in, it was inconvenient for people to have to click Edit to enter the info.) Apparently I immediately forgot unchecking those settings as soon as I'd done it, and thus adding the fieldset had no effect. Only just now did I realize what I'd done. D'oh!

Ugh. A year later I'm updating the webform (it's registration for an annual conference, which is why I haven't looked at it in a year) and the address is no longer being passed. The site is running the same version of ECO as last year (although I tested on my dev site with the latest ECO dev, and still no luck) and Webform 6.x-3.11 — I don't know what version of Webform I would have had a year ago, but from the release dates it looks like 6.x-3.2 is a possibility.

So I'm wondering if something changed in Webform during that time that would have affected the way the form_state syntax works for a multi-page form with fieldsets? Or if anyone has other ideas about what could have made this stop working?

Update: It appears that it works fine if you don't proceed to the second page of the form (which only appears conditionally). If you go straight from page 1 (where the address fields are) to checkout, then the values are passed. But if you answer the questions in such a way that you proceed to page 2 of the form before checkout, then Ubercart doesn't get the values. (This makes me think that nothing actually changed; this part probably didn't work last year either.)

Is it possible to resolve this? Thanks for any help anyone can provide!

As a workaround (in case anyone else is experiencing this problem) I installed the Webform Conditional module so I could use same page conditionals, and thus eliminated the second page of the form. Once everything was on one page, the values pass correctly.

Also see related issue #943838: Billing pane showing cached data with multi-page webform (I guess that's the one I should have updated with my commend in #6, rather than reopening this, but I didn't originally realize it was a multi-page problem.)
