我已经写了上面的代码来删除我在普通PHP文件中从我的帐户上传youtube视频 . 它工作正常 . 当我在drupal中实现相同时，它给我302找到状态并终止ajax http请求 .

$element['remove_button'] = array(
  '#type' => 'button',
  '#value' => t('Remove Video'),
  '#id' => 'youtube-button-remove',
  '#attributes' => array('class' => array('youtube_video_uploader_option')),
  '#ajax' => array(
    'callback' => 'youtube_video_uploader_ajax_remove',
  ),
);

删除视频按钮我们称之为ajax回调函数 - youtube_video_uploader_ajax_remove

function youtube_video_uploader_ajax_remove($form, $form_state) {
 $node=$form['nid']['#value'];
 // $_SESSION['videoid']=$node;
 $commands[] = ajax_command_invoke("#youtube-story-id", "val", array(''));
 $commands[] = ajax_command_invoke("#youtube_preview_launcher", "html", array(''));
 youtube_video_delete_video($node);
 print ajax_render($commands);
 exit;
 }
 function youtube_video_delete_video($nid)
 {
 global $base_url;

 $video_node=node_load($nid);
 //print_r($video_node);

if($video_node->type=='child_profile_videos')
{
    $videoid=$video_node->field_child_profile_video['und'][0]['Video'];
}
if($video_node->type=='youtube_videos')
{
    $videoid=$video_node->field_video_['und'][0]['Video'];
}

if($video_node->type=='programs_videos')
{
    $videoid=$video_node->field_program_video['und'][0]['Video'];
}
$options = youtube_video_uploader_options();

}

这是ajax回拨功能，依次调用删除视频，以便Youtube API删除视频

你可以帮我解决这个错误吗？
