Drupal taxonomy term list
Here’s a useful script for anyone who wants to display a list of terms for any given vocabulary. It seems that many people are asking this question and I’ve seen some very complicated solutions to the problem. However there was one that came very close from tela-web.com
I adapted the script very slightly as I wanted to be able to display a list of terms for a particular vocabulary, but only if a published node had been associated with it. So I added the taxonomy_term_count_nodes() function to check for that.
<?php
$vid = 2; /* <—- put correct vocabulary ID here */
$terms = taxonomy_get_tree($vid);
print "<ul>";
foreach ( $terms as $term ) {
if (taxonomy_term_count_nodes($term->tid) > 0) {
print "<li>".
l($term->name,’taxonomy/term/’.$term->tid, array(’title’ => $term->name)).
"</li>";
}
} /* end foreach */
print "</ul>";
?>
Simply go and create a new block and add this code (make sure you turn on PHP code for the input format!) and plug in the relevant $vid (vocabulary ID). Hope this helps.
