Expand menu on node page

Hello Dmitriy.trt, nice work!

This feature has been requested many times :) If you can formulate this as a patch (so others can also test) I think it could make a good addition.

I actually learned a few things from your code. There are a few changes to make this integrate nicely with taxonomy menu. If you place the options in taxonomy_menu_taxonomy_menu_options() then they will automatically show up on the vocab edit page. In your own module you could use hook_taxonomy_menu_options (http://drupal.org/node/380652).

Then you would need to make a few small changes to your hook_init and _taxonomy_menu_trails_set.

How does this work when a node has multiple terms?

Make sure you use taxonomy_menu_create_path to return the path created by taxonomy menu.

/**
 * Create the path for the vid/tid combination.
 *
 * @param $vid
 * @param $tid
 * @return string
 *  path
 */
function taxonomy_menu_create_path($vid, $tid) {
  //get the path function for this vocabulary
  $function = variable_get('taxonomy_menu_path_'. $vid, 'taxonomy_menu_path_default');
  //run the function
  return $function($vid, $tid);
}

Please work on this. I think it would be a great addition!

This would be great, I would love to test it.

oh my $deity!

I've been looking for this feature long time, great addition!

Please implement tax menu trail in tax menu; espacially version 3!

I think feature described by issue author is very important. It can be implemented something like this:

function taxonomy_node_get_terms($node, $key = 'tid') {
  static $terms;
  if (!isset($terms[$node->vid][$key])) {
    $query = db_select('taxonomy_index', 'r');
    $t_alias = $query->join('taxonomy_term_data', 't', 'r.tid = t.tid');
    $v_alias = $query->join('taxonomy_vocabulary', 'v', 't.vid = v.vid');
    $query->fields( $t_alias );
    $query->condition("r.nid", $node->nid);
    $result = $query->execute();
    $terms[$node->vid][$key] = array();
    foreach ($result as $term) {
      $terms[$node->vid][$key][$term->$key] = $term;
    }
  }
  return $terms[$node->vid][$key];
}

function taxonomy_menu_init() {
  $item = menu_get_item();
  if ($item['page_callback'] == 'node_page_view') {
    $node = $item['page_arguments'][0];
    $terms = taxonomy_node_get_terms($node);
    $term = reset($terms);
    $item['href'] = 'taxonomy/term/' . $term->tid;
    menu_set_item(NULL, $item);
  }
}

Is it possible to add this feature to Taxonomy Menu?
