要获取节点编辑表单，您需要包括 node.pages.inc 。

To get a node edit form, you need to include node.pages.inc.

<?php
  // required for Drupal 6
  module_load_include('inc', 'node', 'node.pages'); 
  // which nodeform you want
  $node_type = 'YOURNODETYPE';
  $form_id = $node_type . '_node_form';
  // maybe add current users info
  global $user;
  // create a blank node
  $node = array(
    'uid' => $user->uid,
    'name' => (isset($user->name) ? $user->name : ''),
    'type' => $node_type,
  );
  // Invoke hook_nodapi and hook_node
  node_object_prepare($node);
  // Or you can also use an exiting node, for example
  // $node = node_load(123);
  // and the display the form:
  $output = drupal_get_form($form_id, $node);
?>
