taxonomy_node_get_terms_by_vocabulary returns empty array

Hi Caroline,

This is a fantastic turorial!

I just have one issue: Even after breaking out vocabularies, the the order of the vocabs themselves are still in alphabetically sorted by the terms within them (so if Vocab 1 has term 'Saturn' and Vocab 2 has term 'Apple', then group 2 will display first.

This is a problem for me for two reasons:
* I want the vocabularies to show in the same order for visual consistency
* Also because I'm using pathauto to generate the node's path according to a token for the top-level term. Ideally there could be some way to be sure that the first term within the Vocab sorted at the top of the taxonomy sort order (in admin/content/taxonomy) will always be the first term.

Do you have any advice for modifying the code to account for this?

Here's the code I'm using from your tutorial BTW (slightly adapted to Zen theme's _preprocess_node function):

/**
 * Override or insert variables into the node templates.
 *
 * @param $vars
 *   An array of variables to pass to the theme template.
 * @param $hook
 *   The name of the template being rendered ("node" in this case.)
 */
function dlc1_preprocess_node(&$vars, $hook) {
  //$vars['sample_variable'] = t('Lorem ipsum.'); KEEP COMMENTED OUT FOR NOW
  // BELOW IS FROM 11heavens.com/putting-some-order-in-your-terms FOR BREAKING OUT TERMS BY VOCAB
  // If we have any terms...
  if ($vars['node']->taxonomy) {
    // Let's iterate through each term
    foreach ($vars['node']->taxonomy as $term) {
      // We will build a new array where there will be as many
      // nested arrays as there are vocabularies
      // The key for each nested array is the vocabulary ID     
      $vocabulary[$term->vid]['taxonomy_term_'. $term->tid]  = array(
        'title' => $term->name,
        'href' => taxonomy_term_path($term),
        'attributes' => array(
          'rel' => 'tag', 
          'title' => strip_tags($term->description)),
        );       
    }
    // We will get rid of the old $terms variable
    unset($vars['terms']);
    // And build a new $terms
    foreach ($vocabulary as $vid => $terms) {
      // Getting the name of the vocabulary
      $name = taxonomy_vocabulary_load($vid)->name;
      // Using the theme('links', ...) function to theme terms list
      $terms = theme('links', $terms, array('class' => 'links inline'));
      // Wrapping the terms list
      $vars['terms'] .= '<div class="vocabulary taxonomy_vid_';
      $vars['terms'] .= $vid;
      $vars['terms'] .= '">';
      $vars['terms'] .= $name;
      $vars['terms'] .= ':&nbsp;';
      $vars['terms'] .= $terms;
      $vars['terms'] .= '</div>';
    }
  }   
}

Thanks in advance for any thoughts on how to deal with this :)

Hi heather, do you have a moment?

I used your preprocess method (which is great by the way), on my localhost it works fine, but on my live testing server I get the error unexpected T_OBJECT_OPERATOR in line XXX

Which is...

  $name = taxonomy_vocabulary_load($vid)->name;

Main difference between the two servers is that my localhost runs PHP5 (where it works) and the testing server is PHP4 (no worky).

Any advice?
