sort taxonony links ($terms) by vocabulary ($vid)
[Note: An alternative method using template.php can be found here: http://drupal.org/node/133223 ]
I figured out a way to sort term links by vocab - this actually works (!) in node.tpl.php 465 (that's only for phphtemplate themes). It does look a bit clumsy - If anyone can tidy it up a bit I'd be very grateful. It probably belongs in the template.php really ... but I'm happy to just have it working at all!
What it does is create a new set of links for each vocab group of terms rather than just having all terms in a single row. eg the code below would produce something like:
# Submitted by: JohnG on 08 Mar 2006
# Forums: newbies - hacking - drupal
# Articles: contributed - in good faith - GPL
Please note, that the code below only processes terms for a single vocab each time - in the example (vid) 27 and 28. You need to replace all the occurrances of 27 with the vid of your favourite vocab.
You can copy&paste these code-chunks as often as you like to cover all your vocabs if you like, as long as you remember to edit all the '27's correctly it will work.
One more thing, I put all instances of this vocab filter script between the <?php if ($terms): ?> ... <?php endif; ?> tags and it works happily.
so it goes something like:
<?php if ($terms): ?><?php /* sort taxonomy links by vocabulary 27 */
$terms27 = taxonomy_node_get_terms_by_vocabulary($node->nid, 27);
if ($terms27) {
print '<div class="terms">Forums: ';
foreach ($terms27 as $key => $term27) {
$lterm27 = l($term27->name, 'taxonomy/term/'.$term27->tid);
print $lterm27.' - ';
}
print '</div>';
}
?><?php /* sort taxonomy links by vocabulary 28 */
$terms28 = taxonomy_node_get_terms_by_vocabulary($node->nid, 28);
if ($terms28) {
print '<div class="terms">Articles: ';
foreach ($terms28 as $key => $term28) {
$lterm28 = l($term28->name, 'taxonomy/term/'.$term28->tid);
print $lterm28.' - ';
}
print '</div>';
}
?>repeat for each vocab vid as needed and then close the
<?php
if ($terms):
?><?php endif; ?>enjoy!
Generic version
If you want a more generic version of this the following code will loop through all vocabularies and output the related terms:
<?php if ($terms): ?><?php
$vocabularies = taxonomy_get_vocabularies();
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, $vocabulary->vid);
if ($terms) {
print '<div class="terms"><h1>' . $vocabulary->name . ':</h1> ';
foreach ($terms as $term) {
print l($term->name, 'taxonomy/term/'.$term->tid) . ' ';
}
print '</div>';
}
}
}
?>
<?php endif; ?>

tooltips
Thanks a lot for this code, I was looking exactly for this :-)
I made one single change. Normally categories will add the term description as a tooltip (title attribute), and the code above is not doing this. Just add one more parameter to the function that creates the link:
<?php...
print l($term->name, 'taxonomy/term/'.$term->tid, array('title' => $term->description) ) . ' ';
...
?>
Minor Thing
This is also exactly what I was looking for! Thank you!
Would it be possible to separate the multiple terms under the same vocab with a comma or straight bracket? Can you tweak the snippet? I would greatly appreciate it.
Sorry for the delay...!
If you haven't sorted this yet here is the code to add a comma - for a straight bracket change the comma on line that reads:
print l($term->name, 'taxonomy/term/'.$term->tid) . ', ';<?phpif ($terms):
?>
<?php
$vocabularies = taxonomy_get_vocabularies();
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, $vocabulary->vid);
if ($terms) {
print '<div class="terms"><h1>' . $vocabulary->name . ':</h1> ';
foreach ($terms as $term) {
print l($term->name, 'taxonomy/term/'.$term->tid) . ', ';
}
print '</div>';
}
}
}
?>
<?phpendif;
?>
Trim added
I just added a trim to remove the last separation:
<?php
$vocabularies = taxonomy_get_vocabularies();
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, $vocabulary->vid);
$termslist = '';
if ($terms) {
print '<div class="terms">' . $vocabulary->name . ': ';
foreach ($terms as $term) {
$termslist = $termslist.l($term->name, 'taxonomy/term/'.$term->tid) . ' | ';
}
print trim ($termslist," |").'</div>';
}
}
}
?>
And you can use the code at /node/38768 to get a solution for alpha sorting.
Now I use t() for terms
Now I use t() for terms too:
<?php$vid = 5; /* vocabulaire 5 = Fruits */
$result = db_query("SELECT t.tid, t.name FROM {term_data} t, {term_node} r WHERE r.tid = t.tid AND r.nid = %d AND t.vid = %d ORDER BY weight, name", array($node->nid, $vid));
while ($term = db_fetch_object($result)) {
$tags[] = l(t($term->name), 'taxonomy/term/' . $term->tid);
}
if ($tags) {
print t("Products") . ": " . implode(' | ', $tags);
}
?>
Using taxonomy_term_path
I modified the code to use taxonomy_term_path. This is for vocabularies 1 and 2:
<?php
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, 1);
foreach ($terms as $term) {
$tags[] = l($term->name, taxonomy_term_path($term));
}
print t("Vocab 1 Terms") . ": " . implode(' | ', $tags);
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, 2);
foreach ($terms as $term) {
$tagsTwo[] = l($term->name, taxonomy_term_path($term));
}
print t("Vocab 2 Terms") . ": " . implode(' | ', $tagsTwo);
?>
Sort terms when t() is used
To sort alphabetically terms for i18n sites, I just tried to apply asort to the $tags array. I then needn't anymore of my previous use of db_query(). It works but not when l() is used. The following code then doesn't display hyperlinks of terms, it just displays the terms as text.
The following sample if for the vocabulary 5.
<?php$vid = 5; /* vocabulaire 5 = Fruits */
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, $vid);
foreach ($terms as $term) {
$tags[] = t($term->name) ;
}
if ($tags) {
asort($tags);
print t("Products") . ": " . implode(' | ', $tags);
}
?>
I don't know how to sort $tag if
$tags[] = l(t($term->name), taxonomy_term_path($term));

print the term description
Hi there,
If you're using "t" for terms how then do you also print out the term description as above?
I'm trying to print out the term used within a vocabulary on a cck node , but also include the term description.
Thanks for any help (i'm a tragic php dunce)

semantic markup
Thanks all, this is a very useful snippet. I made a small change, for those who care about the semantic web: I put the results in a definition list. My code:
<dl class="taxonomy">
<?php
$vocabularies = taxonomy_get_vocabularies();
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, $vocabulary->vid);
$termslist = '';
if ($terms) {
print '<dt class="vocabulary-name">' . $vocabulary->name . ':</dt><div class="vocabulary-terms">';
foreach ($terms as $term) {
print '<dd class="term-name">'.l($term->name, 'taxonomy/term/'.$term->tid) . '</dd>';
}
print '</div>';
}
}
}
?>
</dl>
adding class to taxonomies for styling purposes
Hi All, i've been based on this code to add the vocabulary name as a class to an unordered list of taxonomy items. This way you can later customize with CSS the style each taxonomy item will have depending on the vocabulary they belong.
- I've deleted the separator
- the unordered list tags (ul and li) add semantics to the code.
- I think it's easy to do (i'm not a php or drupal expert) and it should be in core, adding extra class to all elements will help a lot Drupal to be more popular for web designers!.
-I've put this in the taxonomy section of node.tpl.php from the Zen theme, not sure if this is the best way to do it.
<?php if (count($taxonomy)):$vocabularies = taxonomy_get_vocabularies();
print '<ul class="taxonomy-section">';
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node->nid, $vocabulary->vid);
if ($terms) {
print '<li class="taxonomy ' . $vocabulary->name . '">';
foreach ($terms as $term) {
print l($term->name, 'taxonomy/term/'.$term->tid);
}
print '</li>';
}
}
}
print '</ul> <!-- /taxonomy-section -->';
endif; ?>
Here you have an screenshot of what you can do with this and a little of CSS
And here is the CSS beyond it (not yet ready for IE):
.taxonomy-section{padding:0;
font-size:9pt;
list-style-type:none;
clear:both;}
.taxonomy-section li{
float:left;
margin:0;}
.taxonomy a{
padding:5px;
padding-left:20px;
margin-bottom:30px;
margin-right:3px;
border: solid 1px #85be94;
border-left-width:5px;
color:#333333;
text-decoration:none;
background: url(images/tag_green.png) #a5deb4 2px 6px no-repeat;}
.node-type-product .taxonomy a:hover{

.node-type-product .linea a{
background: url(images/tag_yellow.png) #f9f7e6 2px 6px no-repeat;

.node-type-product .linea a:before{

.node-type-product .General a:before{

$vocabularies = taxonomy_get_vocabularies();[...]
$terms = taxonomy_node_get_terms_by_vocabulary(...);
Just to let you know: these add extra SQL queries to your page (they are not cached).
And instead of:
l($term->name, 'taxonomy/term/'.$term->tid, ...)Better use:
l($term->name, taxonomy_term_path($term->tid), ...)(So that 'forum.module' and 'image_gallery.module' and lots other can specialize the link.)
D6 for all Vocabularies-and add Vocab to class div
HI all,
I need to add a specific div class to each vocabulary, so I came up with this variation (see the print statements):
<?php
if (count($taxonomy)):
$vocabularies = taxonomy_get_vocabularies();
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node, $vocabulary->vid);
$vocab = $vocabulary->name;
$termlist = '';
if ($terms) {
print '<div class= "';
print $vocab;
print '">' . $vocabulary->name . ': ';
foreach ($terms as $term) {
$termlist = $termlist.l($term->name, taxonomy_term_path($term->tid) . ', ');
print trim($termlist, ", ").'</div>';
}
}
}
}
print '<!-- /end of terms -->';
endif;
?>
So now my prints out with the actual vocabulary term; which means that each vocabulary can be styled differently. Yea!
ie
I have three vocabularies: oranges, pears and apples.
Splitting up the print functions lets me print out this:
Oranges:
Pears:
Apples:
With my small php skills, this took me a while to figure out, so I'm posting to save someone else some time.

works for 6
Thanks ConnieC, this worked great to display vocabularies on separate lines. One question, how can you separate the terms with a comma or other symbol using this code?
actually comment http://drupal.org/node/53089#comment-1493216 worked this all out.
Drupal6?
Is there anyway do update this to work with drupal6 too?
Thx
Drupal 6
Works for me in D6...
<?phpif ($terms):
// replace '4' with your vocabulary ID
$terms = taxonomy_node_get_terms_by_vocabulary($node, 4);
if ($terms) {
foreach ($terms as $key => $term) {
$items[] = l($term->name, taxonomy_term_path($term), array('attributes' => array('rel' => 'tag', 'title' => $term->description)));
}
print '<p>' . t("Filed in: ") . implode(', ', $items) . '</p>';
// alternativle comment out the above and uncomment the following to theme as an item list.
//print theme('item_list', $items);
}
endif;
?>
Problem
I got a problem with this snippet:
I got 2 taxonomy term, with this snippet when I print the first one (number 1) everything is ok; but in the second call (taxomony term nr2) I have all the terms (taxonomy 1+2) and not the taxonomy 2 alone.
Any suggestion?
Arr, I see, yes me so lazy,
Arr, I see, yes me so lazy, sorry... wipped that out a bit too fast by the l@@ks..
See the "$items" bit, add the vocab id to it and it should solve your problem... i.e...
<?phpif (count($taxonomy)):
// replace '4' with your vocabulary ID
$terms = taxonomy_node_get_terms_by_vocabulary($node, 4);
if ($terms) {
foreach ($terms as $key => $term) {
$items4[] = l($term->name, taxonomy_term_path($term), array('attributes' => array('rel' => 'tag', 'title' => $term->description)));
}
print '<p>' . t("Filed in: ") . implode(', ', $items4) . '</p>';
// alternatively theme as an item list.
//print theme('item_list', $items4);
}
endif;
?>
Subscribing, any solution
Subscribing,
any solution for not doing a database-query on D5?
$vocabularies = taxonomy_get_vocabularies();[...]
$terms = taxonomy_node_get_terms_by_vocabulary(...);

Sorting Taxonomy on Node.tpl.php in Drupal 5
I have tried many examples to sort my terms alphabetically from one vocabulary and print them on my node.
Below is the solution that worked for me.
http://drupal.org/node/133223#comment-634019
I believe the difference is that this version is calling the node's taxonomy which is already sorted alphabetically rather than calling all the terms that are associated with the node which seems to default to sorting by the term id (tid) or weight rather than the term name.
taxonomy_node_get_terms_by_vocabulary — gets the terms but orders them by weight then tid.
where as
$node->taxonomy gets the terms from the node without ordering by weight or tid
Please let me know if my assumptions are wrong.
Hopefully this will help others.
I'd like to print out terms
I'd like to print out terms from one vocabulary in an orderly manner which this snippet more than does, however if I add a php print $terms anywhere after (and only after, if I use the standard php print $terms beforehand everything works alright) this snippet the output is "array". Do you or does anyone know why this is? I would like to have terms from other vocabularies printed underneath the vocabulary that comes out orderly.
better approach...
All round this is a better method:

A very odd issue
I've put this snippet into my node.tpl.php, and oddly enough it works for one term and its subterms, but for other terms and its subterms they are displayed backwards (subterm 3 << subterm 2 << subterm 1 << term). The hierarchy is still accurate (ie if I were to click on subterm 1 it would be recognized as subterm 1 and not subterm 3) so I know it is not an error on the part of the taxonomy module.
