Drupal: Get a comma-separated list of categories (taxonomy)
Written by gerard on Saturday 2 May 2009
Drupal's default way of displaying categories really bugs me. They compile all the categories into an unordered list, which adds a lot of pointless complexity to the theme.
Coming from the WordPress school, I'd much prefer to have a comma-separated list of categories. Well, after an epic battle with my node.tpl.php file and much searching on the Interwebs, I've come up with a solution. It's based heavily on a code snippet used in this Lullabot article.
Essentially, what we need to do is parse through all the terms, build a link for each taxonomy term and then use the implode function to build the comma separated list. Here's a sample of the code I'm using:
<?php
<?php
$term_links = array();
// "implode" makes the terms comma-separated
foreach ($node->taxonomy as $term) {
$term_links[] = l($term->name, 'taxonomy/term/' . $term->tid);
}
print implode(', ', $term_links);
?>
?>I'm currently using this directly in the node.tpl.php, but what I'd really like to do is wrap this in a function and place it in the template.php file so that I can redistribute it with my theme when I make it available. And so that I can carry it across to other themes I might design.
Any hints or tips along those lines would be greatly appreciated!

Moving the code to
Moving the code to template.php is easy.
In template.php your (modified) code:
<code>
function phptemplate_preprocess_node(&$vars) {
// Taxonomy hook to show comma separated terms
if (module_exists('taxonomy')) {
$term_links = array();
foreach ($vars['node']->taxonomy as $term) {
$term_links[] = l($term->name, 'taxonomy/term/' . $term->tid);
}
$vars['node_terms'] = implode(', ', $term_links);
}
}
</code>
In the node template (node.tpl.php and what have you):
<code>
[?php if ($terms) { ?]
[div class="tags"]
[span][?php print t('Tags'); ?]:[/span] [?php print $node_terms; ?]
[/div]
[?php } ?]
</code>
(I replaced the angled brackets, not sure if they would display otherwise.)
Another great code snippet I just found here: http://www.kobashicomputing.com/creating-a-comma-delimited-taxonomy-list...

PS: (1) your CAPTCHAs are extermely difficult, and (2) I had difficulty entering this code in your editor.

As a matter of fact, change the code to include a title:
$term_links[] = l($term->name, 'taxonomy/term/' . $term->tid, array(
'attributes' => array(
'title' => $term->description
)
)
);

Hey thanks guys, very helpful
Hey thanks guys, very helpful snippet. Easy to do with views, but not with taxonomy terms it seems.
