我有点困惑。我创建了一个带有一个文本框和一个提交按钮的简单表单。现在我想使用 taxonomy_get_vocabularies() 函数添加分类术语的选择/选项下拉框。

 $vocabularies = taxonomy_get_vocabularies('my_type');

我的问题是如何将词汇表转换为“Drupal 方式”。Drupal 定义形式的方式似乎相当僵化。另外，如果存在相关分类术语，我怎么能做出这个条件。

function my_form_name($form_state) {

// A Short question.
  $form['title'] = array(
    '#type' => 'textfield',
    '#title' => t('Question'),
    '#default_value' => $node->title,
    '#required' => TRUE,
    '#weight' => 1,
    '#description' => t('A text box goes here '),   
  );

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('submit'),
    '#weight' => 7,
  );

  return $form;

我在自定义表单中做类似的事情，发现使用 taxonomy_get_tree 更容易，将词汇代码作为函数的参数。见下文：

//get the list of locations from taxonomy to use in the dropdown
$dropdown_source = taxonomy_get_tree(2);
$dropdown_array = array('0' => '--none--');
foreach ($dropdown_source as $item) {
$key = $item->tid;
$value = $item->name;
$dropdown_array[$key] = $value;
}

//location filter dropdown
$form['filterset']['locationfilter'] = array(
  '#weight' => '1',
  '#key_type' => 'associative',
  '#multiple_toggle' => '1',
  '#type' => 'select',
  '#options' => $dropdown_array,
  '#title' => 'Filter by location',
);

unset($dropdown_array);

我已经为我的模块（drupal 7）编写了这个辅助函数：

/**
 * helper function to get taxonomy term options for select widget
 * @arguments string $machine_name: taxonomy machine name
 * @return array of select options for form
 */
function MYMODULE_get_tax_term_options($machine_name){
    $options = array( '0' => '');

    $vid = taxonomy_vocabulary_machine_name_load($machine_name)->vid;

    $options_source = taxonomy_get_tree($vid);

    foreach($options_source as $item ) {
        $key = $item->tid;
        $value = $item->name;
        $options[$key] = $value;
    }

    return $options;
}

然后，您可以在 $form 中的 #options 上调用此函数：

$form['field_name'] = array(    
  '#options' => MYMODULE_get_tax_term_options('taxonomy_machine_name'),
);

感谢你的及时回复！我想我是这样解决的。

$form['limiter'] = array(
    '#type' => 'select',
    '#title' => t('Choose a value'),
    '#id' => 'limiter', 
    '#options' => get_faq_terms(),
  );  

function get_faq_terms() {  
    // get the vid value from vocabulary_node_types file
    $result = db_query("SELECT * FROM vocabulary_node_types WHERE type = 'my_type' ");  
    $node = db_fetch_object($result) ;
    $vid = $node->vid ; 

    // get corresponding term names from term_data file
    $items = array();
    $terms = taxonomy_get_tree($vid);
    foreach ( $terms as $term ) {
        $count = taxonomy_term_count_nodes($term->tid);
        if ($count) {       
            $items[$term->tid] = $term->name;
        }
    }

这是drupal方式 - _taxonomy_term_select()

我认为您可以使用该功能：taxonomy_form

在这里你有文献：taxonomy_form

这是在 Drupal 7 中的操作方法

// Populate FAPI select box from vocabulary term values.
// In this case term_reference field is field_category
$form = array();
$form['category_default'] = array(
  '#type' => 'select',
  '#title' => t('Default category'),
  '#options' => taxonomy_allowed_values(field_info_field('field_category')),
  '#description' => t('The selected category will be shown by default on listing pages.')
);
return $form;

在分类模块的 taxonomy.admin.inc 文件中研究如何做到这一点

/**
 * Form builder to list and manage vocabularies.
 *
 * @ingroup forms
 * @see taxonomy_overview_vocabularies_submit()
 * @see theme_taxonomy_overview_vocabularies()
 */
function taxonomy_overview_vocabularies() {
  $vocabularies = taxonomy_get_vocabularies();
  $form = array('#tree' => TRUE);
  foreach ($vocabularies as $vocabulary) {
