NextGEN Gallery是Wordpress中著名的相册插件,遗憾的是不支持中文等unicode字符，本文将介绍如何将目录转换为拼音（添加图集时）。

以NextGEN 1.6.2为例：

“新增图集/图片”的路径是：admin.php?page=nggallery-add-gallery，我们在nextgen-gallery/admin/admin.php中查找“nggallery-add-gallery”，
复制代码 代码如下:
switch (

GET[''page'']){
case "nggallery-add-gallery" :
include_once ( dirname (__FILE__) . ''/functions.php'' ); // admin functions
include_once ( dirname (__FILE__) . ''/addgallery.php'' ); // nggallery_admin_add_gallery
$ngg->addgallery_page = new nggAddGallery ();
$ngg->addgallery_page->controller();
break;

类nggAddGallery在addgallery.php中，鼠标悬停在”新增图集“Tab上时从浏览器的状态栏可以看到URL是 admin.php?page=nggallery-add-gallery#addgallery , 在addgallery.php中查找"addgallery"看到其调用了：
nggAdmin::create_gallery($newgallery, $defaultpath);
nggAdmin类位于functions.php中，create_gallery函数修改如下：(红色粗体是新增加的行)
复制代码 代码如下:
require_once(''cn2pinyin.php'');
/**
* nggAdmin - Class for admin operation
*
* @package NextGEN Gallery
* @author Alex Rabe
* @copyright 2007-2010
* @access public
*/
class nggAdmin{
/**
* create a new gallery & folder
*
* 添加中文支持 by:Elf Sundae
*
* @class nggAdmin
* @param string $gallerytitle
* @param string $defaultpath
* @param bool $output if the function should show an error messsage or not
* @return
*/
function create_gallery($gallerytitle, $defaultpath, $output = true) {
global $wpdb, $user_ID;
// get the current user ID
get_currentuserinfo();
//cleanup pathname
$galleryname = sanitize_file_name( $gallerytitle );
// 中文转换为拼音
$galleryname = cn2pinyin($galleryname,1);
$galleryname = apply_filters(''ngg_gallery_name'', $galleryname);
$nggpath = $defaultpath . $galleryname;
$nggRoot = WINABSPATH . $defaultpath;
$txt = '''';

其中cn2pinyin是汉字转换为拼音的函数，位于cn2pinyin.php（新建此文件）中。
cn2pinyin.php
复制代码 代码如下:
<?php
/**
*
* 中文转换为拼音
*
*/
function cn2pinyin( String, Code=''gb2312'') {
DataKey = "a|ai|an|ang|ao|ba|bai|ban|bang|bao|bei|ben|beng|bi|bian|biao|bie|bin|bing|bo|bu|ca|cai|can|cang|cao|ce|ceng|cha" .
"|chai|chan|chang|chao|che|chen|cheng|chi|chong|chou|chu|chuai|chuan|chuang|chui|chun|chuo|ci|cong|cou|cu|" .
"cuan|cui|cun|cuo|da|dai|dan|dang|dao|de|deng|di|dian|diao|die|ding|diu|dong|dou|du|duan|dui|dun|duo|e|en|er" .
