[SOLVED] Get correct delivery state

[d.iandoli75]

Hi to all,

in this row I get the iso code of Billing Address Country:

$fattura_invoice->appendChild($domtree->createElement('CustomerProvince', $state->iso_code));

I need to do the same thing but with Shipping Address Country

I tried to add code like this: 

$fattura_invoice->appendChild($domtree->createElement('DeliveryProvince', $delivery_address->state->iso_code));

Whats wrong?

Thanks to all

I found a mistake in the lines and I Solved.

here below the code BEFORE the solution:

if (!empty($delivery_address->id_state)){
                $state = new State($ga->id_state); // deve cercare l'indirizzo nel delivery_address
                $fattura_invoice->appendChild($domtree->createElement('DeliveryProvince', $state->iso_code));

here the code AFTER the solution:

if (!empty($delivery_address->id_state)){
                $state = new State($delivery_address->id_state); // deve cercare l'indirizzo nel delivery_address
                $fattura_invoice->appendChild($domtree->createElement('DeliveryProvince', $state->iso_code));

My snippet was checking the Object State in the wrong instance.

hope this helps someone
