==代码说明==
*$name = iconv('UTF-8', 'GBK', $name); //将UTF-8编码转换成GBK编码。
*$_PAGE['thisTag'] = $tag->getByName($name); //根据TAG名称获取当前TAG的相关信息。
*$tag->clickUp($_PAGE['thisTag']['tagid']); //根据TAGID更新TAG点击数。
*$tagContentIds = $tag->getContentIdsByName($name); //获取当前TAG名称下所有内容ID。
*$content_array = $content->getById($tagIdArray[0]); //根据第一个内容ID获取内容的详细信息。
*$url = ContentFunction::getContentUrl($content_array); //根据内容详细信息获取[[URL]]地址。

==代码修改==
$type为'pinyin'，tag列表将按照拼音进行TAG分组。 如果您不需要按拼音进行TAG分组，下面的代码可以去掉。
<pre>
01	if($type == 'pinyin'){
02	    $name = iconv('UTF-8', 'GBK', $name);
03	}
04	 
05	if($type == 'pinyin'){
06	    $tagContentIds = $tag->getContentIdsByName($name);
07	    $tagIdArray = explode(',',$tagContentIds);
08	    if(count($tagIdArray)<6){
09	        rsort($tagIdArray);
10	        excms_import('EXCMS.content.Content');
11	        $content = new Content();
12	        excms_import('EXCMS.update.ContentFunction');
13	        $content_array = $content->getById($tagIdArray[0]);
14	        $url = ContentFunction::getContentUrl($content_array);
15	         
16	        header("HTTP/1.1 301 Moved Permanently");
17	        header("Location:".$url);
18	        exit();
19	  }

页面参数$_PAGE可以自由修改，根据模板的需要来增加和修改页面参数。模板中可自由调用页面的参数，例如：{$_PAGE.title}显示页面标题。
