我如何通过node_type获取分类词汇

Question

我的节点类型很少，其中一些有一个与分类词汇相关的额外字段。如果我知道该字段存在的字段名称和节点类型，如何获取分类词汇 ID 或名称？

Answer 1

在 Drupal 7 中，字段可以添加到任何实体/包中，并且对于术语参考字段，使用的词汇表是在字段级别设置的，而不是在实体/包级别上设置的。

因此，您不需要查询特定内容类型的字段设置，而只需查询字段本身的设置。词汇机名称存储在从 field_info_field()：

$field_name = 'field_name_of_field';
$info = field_info_field($field_name);

$vocab_keys = array();
foreach ($info['settings']['allowed_values'] as $item) {
  $vocab_keys[] = $item['vocabulary'];
}

// $vocab_keys now contains an array of all vocabulary machine names allowed on this field

希望有帮助

如果您在额外字段中保留术语，则此代码非常有用。

/**
 * Get vocabulary ID by term name applied to node
 */
$tid = $node->your_field[$node->language][0]['tid'];
$term = taxonomy_term_load($tid);

/* $term now is the following object
stdClass Object(
    [tid] => 1
    [vid] => 1
    [name] => Name of term
    [description] => Description of term
    [format] => full_html
    [weight] => 0
    [vocabulary_machine_name] => vocabulary
) */

/**
 * Loading vocabularies
 */
$vocabularies = taxonomy_get_vocabularies();

/* $vocabularies now is the following array
Array(
    [1] => stdClass Object(
        [vid] => 1
        [name] => Forums
        [machine_name] => forums
        [description] => Forum navigation vocabulary
        [hierarchy] => 1
        [module] => forum
        [weight] => -10
    )
    [2] => stdClass Object(
        [vid] => 2
        [name] => Category
        [machine_name] => category
        [description] => 
        [hierarchy] => 1
        [module] => taxonomy
        [weight] => -9

    )
) */

/**
 * Vocabulary searched by you
 */
$vocabulary = $vocabularies[$term->vid];

/* $vocabulary now is the following object
Array(
    [1] => stdClass Object(
        [vid] => 1
        [name] => Forums
        [machine_name] => forums
        [description] => Forum navigation vocabulary
        [hierarchy] => 1
        [module] => forum
        [weight] => -10
    )
) */
