居住地、家乡 ★省★市★县三级联动（免费）

做人要厚道，感谢原帖作者，地址是：
★省★市★地区◆三级联动◆（1.5正式版） 可扩展！

经过研究修改现在适用2.0版本。

0.下载js文件上传js
到文件夹
source/js/里
然后升级数据库
增加数据字段：
用phpmyadmin在uhome数据库的“uchome_spacefield”表里面添加两个字段：
birthsubcity和residesubcity，类型：varchar(20)


SQL语句:
  
ALTER TABLE `uchome_spacefield` ADD `birthsubcity` VARCHAR( 20 ) NOT NULL AFTER `birthcity` ;
ALTER TABLE `uchome_spacefield` ADD `residesubcity` VARCHAR( 20 ) NOT NULL AFTER `residecity` ;

修改地方比较多，请认真对照原来的代码修改.

'residecity' => getstr($_POST['residecity'], 20, 1, 1),
