drupal节点类型hook_insert()

Question

我在构建 drupal 自定义节点类型时遇到了一些麻烦。我创建了一个模块 sj_highcharts，它最终将使用 highcharts api 来提供数据图表。该模块的重点是创建一个节点类型，该节点类型将显示一个表单，供人们与图表 API 交互，将数据存储在一些数据库表中，然后最终输出图表。

问题是，提交表单后，我的 hook_insert 函数甚至 hook_validate 函数都没有被调用，并且没有任何内容存储到数据库中。我已经发表了声明，以确保他们不会开火。

代码：

  /*
 * Implementation of hook_node_info().
 */
function sj_highcharts_node_info() {
  //defining one node type: 'sj highchart'.
  return array(
    'sj_highcharts_element' => array(
      'name'  => t('Highchart Element'),
      'module' => 'sj_highcharts',
      'description' => t("An element that creates a dynamic chart from specified data."),
      'has_title' => FALSE,
      'has_body' => FALSE,
      'locked' => TRUE,
    )
  );
  //In order to make this an element type, we will have to check the "is element" field in the content type administration page.
}

/**
 * Implementation of hook_form().
 */
function sj_highcharts_form($node) {

  $type = node_get_types('type', $node);
  $form['delimiter'] = array(
      '#type' => 'radios',
      '#title' => t('Data Delimiter'),
      '#description' => t('The character in which the data is delimited.'),
      '#options' => array(t('Tab'), t('Space'), t('Comma')),
      '#default_value' => '',
    );

  $form['x_label'] = array(
      '#type' => 'textfield',
      '#title' => t('x-axis label'),
      '#description' => t('The label to be set and displayed for the x axis.'),
      '#required' => TRUE,

      '#default_value' => '',
      '#rows' => 10,
      '#required' => TRUE,
    );

  $form['y_label'] = array(
      '#type' => 'textfield',
      '#title' => t('x-axis label'),
      '#description' => t('The label to be set and displayed for the y axis.'),
      '#required' => TRUE,

      '#default_value' => '',
      '#rows' => 10,
      '#required' => TRUE,
    );

  $form['type'] = array(
      '#type' => 'select',
      '#title' => t('Select a chart type'),
      '#default_value' => 'Bar',
      '#description' => t('Select a chart type to display data.'),
      '#options' => array(
      '1' => t('Pie'),
      '2' => t('Line'),
      '3' => t('Area'),
      '4' => t('Scatter'),
      '5' => t('Bar'),
    ),
  );

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

  return $form;

我已经盯着这个花了整整一个工作日，但找不到问题。任何关于这方面的指导都会很棒。谢谢布兰登

查看 examples 模块中的 node_example 子模块。它应该可以帮助您指明正确的方向。

您的帖子不清楚您正在使用哪个版本的 drupal。在 Drupal 6 中，您可以直接向表单或表单项添加额外的验证和提交功能。

前任：

  $form['delimiter'] = array(
      '#type' => 'radios',
      '#title' => t('Data Delimiter'),
      '#description' => t('The character in which the data is delimited.'),
      '#options' => array(t('Tab'), t('Space'), t('Comma')),
      '#default_value' => '',
      '#validate' => array('_name_of_custom_validation_function'),
      '#submit' => array('_name_of_custom_submit_function'),
    );
