shortcode help require

我有一个wordpress功能来显示用户最近的5条推文，这些推文可以通过两种方式显示，一种是通过在我创建的管理菜单中直接输入用户ID，另一种是通过自定义字段，

在这里，我想避免自定义字段，并想从短代码开始，我知道我在短代码方面很弱，因为这是我的第二个与之相关的问题，但这个函数需要短代码

这是密码

function tweet_fetcher(){
global $post;
$doc = new DOMDocument();
if((get_option(\'tweetID\'))!=null){
$meta=get_option(\'tweetID\');
$feed = "http://twitter.com/statuses/user_timeline/$meta.rss"; 
$doc->load($feed); 

}
elseif((get_option(\'tweetID\'))==null){
if ( $meta =get_post_meta($post->ID, \'username:\', true) ) { 
$feed = "http://twitter.com/statuses/user_timeline/$meta.rss"; 
$doc->load($feed); 
}

  $outer = "<ul>";
  $max_tweets = 5;   
  $i = 1;
  foreach ($doc->getElementsByTagName(\'item\') as $node) {
    $tweet = $node->getElementsByTagName(\'title\')->item(0)->nodeValue;
    //if you want to remove the userid before the tweets then uncomment the next line.
