drupal 自定义上传 使用upload模块的功能

1)给某种类型的节点 定义一个表单 
function upload_jiangyi_form(&$form_state, $node) {
  global $user;
  $node = (object)$node;
  $form['nid'] = array(
    '#type' => 'hidden',
    '#default_value' => $node->nid,
  );
  // Set the id of the top-level form tag
  $form['#id'] = 'node-form';

  // Basic node information.
  // These elements are just values so they are not even sent to the client.
 
  // Changed must be sent to the client, for later overwrite error checking.
  $form['changed'] = array(
    '#type' => 'hidden',
    '#default_value' => isset($node->changed) ? $node->changed : NULL,
  );
  // Get the node-specific bits.
 
  if (!isset($form['title']['#weight'])) {
    $form['title']['#weight'] = -5;
  }

  $form['#node'] = $node;

  // Add a log field if the "Create new revision" option is checked, or if the
 


  // These values are used when the user has no administrator access.
  foreach (array('uid', 'created') as $key) {
    $form[$key] = array(
      '#type' => 'value',
      '#value' => $node->$key,
    );
  }

  // Add the buttons.
  $form['buttons'] = array();
  $form['buttons']['submit'] = array(
    '#type' => 'submit',
    '#access' => !variable_get('node_preview', 0) || (!form_get_errors() && isset($form_state['node_preview'])),
    '#value' => t('Save'),
    '#weight' => 5,
    //'#submit' => array('node_form_submit'),
  );
   
  //$form['#validate'][] = 'node_form_validate';    //它使用的是原来的验证 
  $form['#theme'] = array($node->type .'_node_form', 'node_form');
 
  return $form;
}

    2)表单提交函数
//表单函数_submit 提交函数
function upload_jiangyi_form_submit(&$form, &$form_state)
{
    /**
       * 用户提交的所有数据在 $form_state['values'] 之中，相当于 $_POST
       */
       global $user;
       $node->files=array();
       $fileObjs = array();
   
       foreach($form_state['values']['files'] as $key=>$value){
           $file = (object)$file;
           $file->list = $value['list'];
           $file->description = $value['description'];
           $file->weight = $value['weight'];
           $file->new = !empty($form['#node']->files[$fid]->new);
           $form['#node']->files[$key] = (array)$file;
           
       }
       //var_dump($form['#node']->files);
       node_save($form['#node']);
       $node=node_load($form_state['values']['nid']);
       // dsm($node); dpm($node);
    drupal_set_message('上传讲义成功!');
}

3)最后好像有个tabledrag.js 使 weight隐藏了,我们把这个js移掉
