Question

How can I change the below code to display only the selected terms in the node. right now all terms which are defined in the vocabulary is displayed

<?php 
$items = taxonomy_vocabulary_machine_name_load('test_categories');
$taxonomy = taxonomy_get_tree($items->vid);
foreach($taxonomy as $key => $items):
  print $items->name;
endforeach;
?>

Answer 1

If you want to print a selected taxonomy value in a node, try this way..

$node = node_load($nid);
//If you have multiple values use foreach.
$tid = $node->yourfieldname['und'][0]['tid'];//if you are using term reference.
$term = taxonomy_term_load($tid);
print $term->name;

Answer 2

For specific node you need to use $info = node_load($nid) where you find your field value using $info->field_name. Using that field you can use foreach something like foreach($info->field_name as as $key => $items).
