UCHome定义了一些全局变量保存常用信息，了解这些变量存放的内容将大大方便我们的二次开发。

以下依次罗列各全局变量所保存的内容：

• $_SC：系统全局配置
• $_SBLOCK：未知
• $_SCONFIG：个人空间配置
• $_SCOOKIE：Cookie信息
• $_SGLOBAL：各类全局信息
• $_SN：昵称信息
• $_TPL：未知
• 举例说明

以上个别全局变量在不同页面的值会有所不同，使用前最好先测试一下值是否存在。

下面是用print_r函数打印出来的各全局变量信息，方便参考（为节省篇幅，删除了部分结构重复的数据）：

举例：

在UCHome上增加一个功能，希望某些群组类别下只允许有群组管理的人才能新建群组，其他人无法新建这些类别的群组。只需修改模板中的cp_mtag.htm文件，将如下代码：

<div class="l_status">1. <strong>请选择一个群组分类</strong></div>
<table><tr>
<!--{eval $i=0;}-->
<!--{loop $fields $value}-->
<td><input type="radio" id="fieldid_$value[fieldid]" name="fieldid" value="$value[fieldid]" onclick="fieldselect(this.value)"><label for="fieldid_$value[fieldid]">$value[title]</label></td>
<!--{if $i%3==2}--></tr><tr><!--{/if}-->
<!--{eval $i++;}-->
<!--{/loop}-->
</tr></table>

更改为：

<div class="l_status">1. <strong>请选择一个群组分类</strong></div>
<table><tr>
<!--{eval $i=0;}-->
<!--{loop $fields $value}-->

<!--{eval if(!($_SGLOBAL['usergroup'][$_SGLOBAL['member']['groupid']]['manageprofield'])){ /*判断当前用户是否有群组管理权限*/}-->
<!--{eval if(in_array($value[fieldid], array(1,4,5,6))) continue;/*过滤不允许普通用户创建的群组*/}-->
<!--{eval } }-->

<td><input type="radio" id="fieldid_$value[fieldid]" name="fieldid" value="$value[fieldid]" onclick="fieldselect(this.value)"><label for="fieldid_$value[fieldid]">$value[title]</label></td>
<!--{if $i%3==2}--></tr><tr><!--{/if}-->
<!--{eval $i++;}-->
<!--{/loop}-->
</tr></table>

简单说明一下：$_SGLOBAL['member']['groupid']返回当前用户的用户组编号，$_SGLOBAL['usergroup'][用户组编号]['manageprofield']返回特定用户组是否有群组管理权限，结合起来判断当前用户是否有群组管理权限。

效果就是当管理员登陆后，新建群组可选择所有分类。

而普通会员登录后，新建群组只能选个别分类。
