如何通过 Forms API 将节点内容提交到节点

Question

我正在尝试存储自定义内容类型 - 节点 在使用drupal 6.26 的drupal 数据库中。 我已经创建了模式表， 但是当我执行表单的提交按钮时 我收到以下错误：

用户警告：键“PRIMARY”查询的重复条目“0-0”： service_form_submit /* 管理员 : service_form_submit */ INSERT INTO 服务（nid、vid、uid、fallbackservice_ids、类别、biblebasic、 阻塞，reason_blocked，创建，开始，停止）值（0、0、0， '', '', '', 0, '', 0, 0, 0 ) 在 /var/www/drupal/modules/service/service.module 在第 261 行。

并且至少没有条目存储在db中，我输入的nid、vid、uid和其他值似乎都不可用。

我如何传递 $node 是否正确？

function service_form(&$node) {
function service_form_submit($node) {

这里是我如何使用 $node 的完整代码？

<?php
/**
* Implementation of hook_node_info().
*/
function service_node_info() {
  // We return an array since a module can define multiple node types.
  return array(
    'service' => array(
      'name' => t('Service'), // Required.
      'module' => 'service',  // Required. Prefix of the callback functions to look for: service_validate(), service_insert(), service_delete()
      'description' => t('Offer your service to the church.'), // Required.
      'has_title' => TRUE,
      'title_label' => t('Please enter your Service Name'),

  );

您使用自定义模块执行此操作有什么特别的原因吗？为什么不直接创建一个新的内容类型？

如果你真的想用你自己的模块来做，你看过examples module吗？ 你真正想看的代码是here
