Location fields

I'm having issue with this combination, but I am successful toward generating a title from locative fields. The following code snippet does work, but the node title is incomplete until I submit the node a second time. I only have "$zip :" as title on the first pass. I have only locations in the US, so the "us-" component of province is not used; only the two-letters state code is relevant.

The gmap API seems to require prior submission. We could peruse there for refinement of procedure and PHP code.

<?php
  global $form_values;
  $node = (array)$form_values;
  $loci = $node['locations'][0];
  $zip = $loci['postal_code'];
  $street = $loci['street'];
  $city = $loci['city'];
  $state = substr($loci['province'], -2);
  if($street) {
    $output = "$zip : $street";
  } else {
    $output = "$zip : $city $state";
  }
  print $output;
?>

I actually found my solution in the location API. The function is slted for deprecation, and seems off-topic here, but I'll post my finding.

After copying my loci array from $node['locations'][0], I defined one array element to reflect my site configuration, and made one location API call.

  $loci['country'] = 'us';
  $loci = location_get_postalcode_data($loci);

My automatic nodetitles implementation is happy.

You can use:
$node->field_lonlat[0][city]

It is working without problem
