Element Children is a great way to dig into arrays with multiple keys
This might appear under a pre-process node
/**
* Override or insert vars into the node template.
*/
function nrdc_preprocess_node(&$vars) {
// Define the node.
$node = $vars['node'];
$nodetype = $node->type;
// Retrive terms on node and loop through each term
// using a $key in place of the array number.
// so that it does not get reset with every pass.
// The array might look something like this in Xdebug
// $vars['field_issue_term']['0']['taxonomy_term']
// $vars['field_issue_term']['1']['taxonomy_term']
// etc...
// Set the linked_terms variable to false before the loop.
$vars['linked_terms'] = FALSE;
// Loop using a key value via element_children.
foreach (element_children($vars['field_issue_term']) as $key) {
// Get the term name.
$term_name = $vars['field_issue_term'][$key]['taxonomy_term']->name;
// Get the term TID.
$term_tid = $vars['field_issue_term'][$key]['taxonomy_term']->tid;
// Convert the term path into an alias.
$term_url = drupal_lookup_path('alias', 'taxonomy/term/' . $term_tid);
}
