I'm trying to show every terms of 2 vocabularies from a node, but I have this situation.
I have 2 vocabularies, somethings like "brands" and "cars".
My node has to be even in BMW and even in "Light Blue."
In my template.tpl i have this function:
function theme479_print_terms($node, $vid = NULL, $ordered_list = TRUE) {
$vocabularies = taxonomy_get_vocabularies();
if ($ordered_list) $output .= '<ul>'; //checks to see if you want an ordered list
if ($vid) { //checks to see if you've passed a number with vid, prints just that vid
$output = '<div class="tags-'. $vid . '">';
foreach($vocabularies as $vocabulary) {
if ($vocabulary->vid == $vid) {
$terms = taxonomy_node_get_terms_by_vocabulary($node, $vocabulary->vid);
if ($terms) {
$links = array();
$output .= '<span class="only-vocabulary-'. $vocabulary->vid . '">';
if ($ordered_list) $output .= '<li class="vocabulary-'. $vocabulary->vid . '">' . $vocabulary->name . ': ';
foreach ($terms as $term) {
$links[] = '<span class="term-' . $term->tid . '">' . l($term->name, taxonomy_term_path($term), array('rel' => 'tag', 'title' => strip_tags($term->description))) .'</span>';
}
$output .= implode(', ', $links);
if ($ordered_list) $output .= '</li>';
$output .= '</span>';
}
}
}
}
else {
$output = '<div class="tags">';
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node, $vocabulary->vid);
if ($terms) {
$links = array();
$output .= '<ul class="vocabulary-'. $vocabulary->vid . '">';
if ($ordered_list) $output .= '<li class="vocabulary-'. $vocabulary->vid . '">' . $vocabulary->name . ': ';
foreach ($terms as $term) {
$links[] = '<span class="term-' . $term->tid . '">' . l($term->name, taxonomy_term_path($term), array('rel' => 'tag', 'title' => strip_tags($term->description))) .'</span>';
}
$output .= implode(', ', $links);
if ($ordered_list) $output .= '</li>';
$output .= '</ul>';
}
}
}
}
if ($ordered_list) $output .= '</ul>';
$output .= '</div>';
return $output;
}
In my node.tpl, I have this:
print theme_print_terms($node, $unordered_list = TRUE);
The result is the following:
Brands: BMW
Colors: Light Blue
How can I get something like the following?
Brands: BMW
Colors: Blue/Light Blue
So with every parent categories. May you help me?
EDIT:
it's possible to show all hierarchy of a vocabulary? for example i have a vocabulary with this structure (Foods>Fruits>Fruit_with_seeds ->apple) but this function only show Fruits>Fruit_with_seeds)
You simply need to check each term for parent terms. If a parent term is found place it in a variable and then prepend it to your link text. A way to check for a term parent:
if ($get_parents = taxonomy_get_parents($term->tid, 'tid')) {
foreach ($get_parents as $parents) {
$parent = $parents->name . '/';
}
}
To add to your link text:
$links[] = '<span class="term-' . $term->tid . '">' . l($parent . $term->name, taxonomy_term_path($term), array('rel' => 'tag', 'title' => strip_tags($term->description))) .'</span>';
All put together: (note: This is a pretty nasty looking function, the HTML should really be separated from the retrieval of term parents to format output in another function).
function theme479_print_terms($node, $vid = NULL, $ordered_list = TRUE) {
$vocabularies = taxonomy_get_vocabularies();
if ($ordered_list) $output .= '<ul>'; //checks to see if you want an ordered list
if ($vid) { //checks to see if you've passed a number with vid, prints just that vid
$output = '<div class="tags-'. $vid . '">';
foreach($vocabularies as $vocabulary) {
if ($vocabulary->vid == $vid) {
$terms = taxonomy_node_get_terms_by_vocabulary($node, $vocabulary->vid);
if ($terms) {
$links = array();
$output .= '<span class="only-vocabulary-'. $vocabulary->vid . '">';
if ($ordered_list) $output .= '<li class="vocabulary-'. $vocabulary->vid . '">' . $vocabulary->name . ': ';
foreach ($terms as $term) {
// Check for terms parent, if found assign to $parent variable
if ($get_parents = taxonomy_get_parents($term->tid, 'tid')) {
foreach ($get_parents as $parents) {
$parent = $parents->name . '/';
}
}
$links[] = '<span class="term-' . $term->tid . '">' . l($parent . $term->name, taxonomy_term_path($term), array('rel' => 'tag', 'title' => strip_tags($term->description))) .'</span>';
}
$output .= implode(', ', $links);
if ($ordered_list) $output .= '</li>';
$output .= '</span>';
}
}
}
}
else {
$output = '<div class="tags">';
foreach($vocabularies as $vocabulary) {
if ($vocabularies) {
$terms = taxonomy_node_get_terms_by_vocabulary($node, $vocabulary->vid);
if ($terms) {
$links = array();
$output .= '<ul class="vocabulary-'. $vocabulary->vid . '">';
if ($ordered_list) $output .= '<li class="vocabulary-'. $vocabulary->vid . '">' . $vocabulary->name . ': ';
foreach ($terms as $term) {
// Check for terms parent, if found assign to $parent variable
if ($get_parents = taxonomy_get_parents($term->tid, 'tid')) {
foreach ($get_parents as $parents) {
$parent = $parents->name . '/';
}
}
$links[] = '<span class="term-' . $term->tid . '">' . l($parent . $term->name, taxonomy_term_path($term), array('rel' => 'tag', 'title' => strip_tags($term->description))) .'</span>';
}
$output .= implode(', ', $links);
if ($ordered_list) $output .= '</li>';
$output .= '</ul>';
}
}
}
}
if ($ordered_list) $output .= '</ul>';
$output .= '</div>';
return $output;
