我正在尝试将参数传递给由“durpal_get_form”调用的表单，该函数是从 JS 脚本在 AJAX 中调用的 PHP 函数。

所以我做了这样的事情：

// Load form
$form = drupal_get_form("_bto_ajax_submenu_organize_form", array(
    'territories' => $territories, 
    'accommodations' => $accommodations, 
    'activities' => $activities,
    'language' => $language,
));

事实是我的表单被构建了两次。第一次我有我的参数值，但第二次它们都等于“NULL”......所以在我的表单提交函数中，我无法取回它们。我试图将它们放在 $form_storage 中的隐藏字段中……没有任何效果。

有任何想法吗 ？

编辑：这是我的代码。有些部分你可能不明白，但至少你会对问题有一个全局的认识。

表格和提交：

/**
 * Organize form 
 */
function _bto_ajax_submenu_organize_form($form, &$form_state, $args)
{
  $form['place'] = array(
    '#prefix' => '<div class="left">',
    '#title' => t('Where do you want to go ?', array(), array('langcode' => $args['language'])),
    '#type' => 'select',
    '#options' => _bto_ajax_submenu_organize_form_get_territories($args['territories'], $args['language']),
  );

  $form['activity'] = array(
    '#title' => t('What do you want to do ?', array(), array('langcode' => $args['language'])),
    '#type' => 'select',
    '#options' => _bto_ajax_submenu_organize_form_get_activities($args['activities'], $args['language']),
    '#suffix' => '</div>'
  );

  $form['accommodation'] = array(
    '#prefix' => '<div class="right">',
    '#title' => t('Where do you want to lodge ?', array(), array('langcode' => $args['language'])),
    '#type' => 'select',
    '#options' => _bto_ajax_submenu_organize_form_get_accommodations($args['accommodations'], $args['language']),
    '#suffix' => '</div>'
  );

  if ($form_state['build_info']['args'][0]['language'] != NULL) {
    switch ($args['language']) {
      case 'fr':
        $form['test'] = array(
          '#type' => 'hidden',
          '#value' => 'fr',
        );
        break;

      case 'en':
        $form['test'] = array(
          '#type' => 'hidden',
          '#value' => 'en',
        );
        break;

      case 'de':
        $form['test'] = array(
          '#type' => 'hidden',
          '#value' => 'de',
        );
        break;

      default:
        $form['test'] = array(
          '#type' => 'hidden',
          '#value' => 'fr',
        );
        break;
    }
  }

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t("Let's go !", array(), array('langcode' => $args['language'])),
  );

  return $form;
}


/**
 * Organize form submit
 */
function _bto_ajax_submenu_organize_form_submit($form, &$form_state)
{
  dsm($form_state['build_info']['args']);
  $values = $form_state['values'];
  $storage = $form_state['storage'];
  $query = array();
  dsm($values);

  // Territory
  if ($values['place'] != 0)
    $query['place'] = $values['place'];

  // Activity
  if ($values['activity'] != 0)
    $query['filter'] = $values['activity'];

  // Hébergements
  if ($values['accommodation'] != 0)
    $query['filter2'] = $values['accommodation'];

  $url = get_node_path('109', $storage['lang']);
  $url = str_replace('fr/', '', $url);
  $url = str_replace('en/', '', $url);
  $url = str_replace('de/', '', $url);
  drupal_goto($url, array('query' => $query));
}

挂钩菜单：

/**
 * Hook menu
 * @return array $items     Contient les items du menu
 */
function bto_menu()
{
    $items = array();
    $items['ajax/%'] = array(
        'access callback' => true,
        'page arguments' => array(1),
        'page callback' => '_bto_ajax',
        'type' => MENU_CALLBACK,
    );
    //...
    return $items;
}

以及形式的调用：

/**
 * Callback ajax route
 * @param  $request 
 */
function _bto_ajax($request) 
{
    extract($_POST);
    switch ($request) {
        // ...             
        case 'menu-principal-organiser':
            $output = _bto_ajax_submenu_load_organize($vars);
            break;        
    }

    print  $output;
}


/**
 * Organize your trip
 */
function _bto_ajax_submenu_load_organize($vars) 
{
    $vars = json_decode($vars);
    $territories = $vars->territories;
    $accommodations = $vars->accommodations;
    $activities = $vars->activities;
    $language = $vars->language;

    // Load form
    $form = drupal_get_form("_bto_ajax_submenu_organize_form", array(
        'territories' => $territories, 
        'accommodations' => $accommodations, 
        'activities' => $activities,
        'language' => $language,
    ));

    // Load packaged offers
    // ...

    // Load template
    $output = theme('submenu-organize', array(
        'form' => drupal_render($form),
        'packaged_offers' => $packaged_offers,
        'language' => $language,
    ));

    return $output;
}

确保Drupal.attachBehaviors()从您的 AJAX 回调中调用它。有关更多详细信息，请参阅Drupal 7 JavaScript API。
