在theme里区别显示一般分类与freetag标签-优快云博客

本文介绍了一个用于改进Drupal站点中节点模板的PHP函数。该函数通过遍历节点的分类术语并重新组织它们来增强显示效果，确保词汇表按ID排序，并使用主题函数呈现术语链接列表。此外，还介绍了如何移除旧的术语变量并创建新的格式化后的术语变量以提高用户体验。

add this function to template.php

function phptemplate_preprocess_node(&$vars) {
  // If we have any terms...
  if ($vars['node']->taxonomy) {
    // Let's iterate through each term.
    foreach ($vars['node']->taxonomy as $term) {
      // We will build a new array where there will be as many
      // nested arrays as there are vocabularies
      // The key for each nested array is the vocabulary ID.     
      $vocabulary[$term->vid]['taxonomy_term_'. $term->tid]  = array(
        'title' => $term->name,
        'href' => taxonomy_term_path($term),
        'attributes' => array(
          'rel' => 'tag', 
          'title' => strip_tags($term->description),
        ),
      );       
    }
    // Making sure vocabularies appear in the same order.
    ksort($vocabulary, SORT_NUMERIC);
    // We will get rid of the old $terms variable.
    unset($vars['terms']);
    // And build a new $terms.
    foreach ($vocabulary as $vid => $terms) {
      // Getting the name of the vocabulary.
      $name = taxonomy_vocabulary_load($vid)->name;
      // Using the theme('links', ...) function to theme terms list.
      $terms = theme('links', $terms, array('class' => 'links inline'));
      // Wrapping the terms list.
