thinkphp 地区管理功能，因为最近有些系统有这方面的需求行业不一样用到区域也不一样，完成70%， ajax 双击修改地区部分没实现，有时间弄下。本来打算移植ecshop 的不过有点麻烦。还是自己写把。数据库部分来自ecshop region表。至于前端部分，参考任何一个城市级联即可实现，高端上档次！
实现效果：
前台代码：<form>
<br>
<table>
<br>
<tr>
<br>
<th>
<br>
{if $region_type=3}{$regionts}：<br>
<input><br>
<input><br>
<input><br>
<input><br>
{/if}<br>
<a>$region_typeyuanshi,'parentid'=>$fuID))}">返回上一级</a><br>
</th>
<br>
</tr>
<br>
</table>
<br>
</form>
<br>
<div>
<br>
<table>
<br>
<tr><td>{$region_type}</td></tr>
<br>
<tr>
<br>

<br>

) ENGINE=MYISAM AUTO_INCREMENT=3417 DEFAULT CHARSET=utf8 COLLATE=utf8_bin数据的话，ecshop 里面region 表和其一样。
