Drupal Taxonomy

在Wordpress中，标签会按照类别显示。不过Wordpress就两种标签：文章分类和标签。

在Drupal中，你可以创建不同类型的标签，如：文章分类，文章地点，涉及人物，天气等等类型(Vocabulary)。但是默认时会将这些标签(Taxonomy Terms)显示在一起，我们可以用下面的代码将这些标签按类别分开显示：

<?php
function yourthemename_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;
}
?>

<?php
if ($terms && !$teaser) { print yourthemename_print_terms($node, $vid = NULL, $unordered_list = TRUE);}
?>
 
<?php
if ($terms && $teaser) { print yourthemename_print_terms($node, $vid = NULL, $unordered_list = FALSE);}
?>
