扩展Scheduler模块形式

Question

嗨，我正在尝试扩展调度器模块表单。我需要的字段作为字段集包含在节点中，作为额外字段引用图像。

/**
 *  Implements hook_form_node_type_form_alter(). 
 */

 function nodequeue_scheduler_form_node_type_form_alter(&$form, $form_state) {

    //This  node type configuration form with schedule options

    $form['scheduler']['nodequeue_sheduler'] = array(
      '#type' => 'fieldset',
      '#title' => t('Nodequeue Scheduler Settings'),
      '#collapsible' => FALSE,
      '#group' => 'scheduler',
      '#weight' => 10,
    );

   }

/**
 * Implements hook_form_FORM_ID_alter().
 */
function nodequeue_scheduler_form_scheduler_node_form_alter(&$form, $form_state) {

   //feldset or vertical tab for scheduler to ammend
$options = array (1,2,3);
// Adding few custom fields
$form['scheduler_settings']['publish_nodequeue'] = array(
 '#type' => 'fieldset',
 '#title' => t('Nodequeue Scheduling settings'),

);
$form['scheduler_settings'] ['publish_nodequeue']['schedule_nodequeue'] = array(
 '#type' => 'checkbox',
 '#default_value' => 1,
 '#title' => t('Add to nodequeue when published')
);

$form['scheduler_settings']['publish_nodequeue']['nodequeue_position'] = array(
 '#type' => 'select',
 '#options' => $options,
 '#title' => t('Position')

);
$form['scheduler_settings']['publish_nodequeue']['publish_on'] = array(
 '#type' => 'textfield',
 '#title' => t('Publish on'),
 '#maxlength' => 30,

);
// function scheduler_mail_form_scheduler_node_form_alter(&$form, $form_state) {
//    $email_enabled = variable_get('scheduler_mail_enable_' . $form['type']['#value'], 0);
//    if (!$email_enabled) {
//      return;
//    }

//    $node = $form['#node'];
//    $settings = _scheduler_mail_load($node);

//    $form['scheduler_settings']['scheduler_mail'] = array(
//      '#type' => 'fieldset',
//      '#title' => t('Email settings'),
//    );
//    $form['scheduler_settings']['scheduler_mail']['scheduler_mail_send'] = array(
//      '#type' => 'checkbox',
//      '#title' => t('Send an email notification when this node is (un)published'),
//      '#default_value' => $settings->send,
//    );
//    $form['scheduler_settings']['scheduler_mail']['scheduler_mail_address'] = array(
//      '#type' => 'textfield',
//      '#title' => t('Use this email address'),
//      '#description' => t('If left blank, email will go to the original author of this node'),
//      '#default_value' => $settings->address,
//      '#maxlength' => 255,
//      '#states' => array(
//        'visible' => array(
//          "input[name='scheduler_mail_send']" => array("checked" => true)
//        ),
//      ),
//    );
//    $form['#validate'][] = '_scheduler_mail_validate';
//    $form['#submit'][] = '_scheduler_mail_submit';
  }

我发现模块调度器邮件，它更改节点类型表单，并添加一些配置字段作为复选框，但没有得到的形式，是在节点编辑形式。在drupal 7我该怎么做？

如果调度程序在窗体上使用hook_form_alter()，而您的模块也在同一表单上使用hook_form_alter()，那么这两个hook_form_alter()函数的执行顺序很重要。显然，在调度程序添加要修改的新表单元素之前，正在调用模块的hook_form_alter()。

Drupal按模块权重顺序执行这些钩子。如果您不设置模块权重，那么我相信它们都默认为相同的值，具有相同权重的钩子将按字母顺序调用(但这不是保证的)。

为了确保在调度器之后调用模块，需要将模块的权重设置为大于调度程序的模块权重。在模块的安装文件中是这样做的：

/**
 * Implements hook_install().
 */
function my_module_install() {
  // Because we need to alter a form that is also altered by the scheduler
  // module, we need to ensure this module gets loaded AFTER the scheduler.
  $weight = db_query('SELECT weight FROM {system} WHERE name = :name', array(':name' => 'scheduler'))->fetchField();
  db_update('system')
    ->fields(array(
      'weight' => $weight + 1
    ))
    ->condition('name', 'my_module')
    ->execute();
}
