drupal - 将选择/选项列表添加到表格

Question

我有点困惑。我用一个文本框和一个提交按钮创建了一个简单的表单。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'); 

我的问题是如何获得词汇表列表到“Drupal方式”。 Drupal定义窗体的方式看起来很僵硬。还有，如果存在相关的分类术语，我怎么能做出这种情况呢？

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; 

Answer 1

我做一个自定义窗体类似的东西，并发现它更容易使用taxonomy_get_tree，与词汇代码作为函数的参数。请看下图：

//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); 

Answer 2

研究如何做，在分类模块的taxonomy.admin.inc文件

/** 
* 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) { 
    ... 

Answer 3

感谢您的及时回复！我想我是这样做的。

$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; 
     } 
    } 

Answer 4

这是Drupal的方式 - _taxonomy_term_select（）

Answer 5

我想你可以使用的功能：taxonomy_form

在这里，你有doumentation：taxonomy_form

Answer 6

我已经为我的模块写了这个帮助函数（drupal 7）：

/** 
* 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; 
} 

然后你就可以在你的$形式呼吁您#options此功能：

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

Answer 7

这里是如何做到这一点在Drupal 7

// 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;
