第十二章：【UCHome二次开发】全局变量

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：

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：

$_SC：系统全局配置

$_SC: Array([dbhost] => localhost[dbuser] => root[dbpw] => 33023[dbcharset] => utf8[pconnect] => 0[dbname] => uchome[tablepre] => uch_[charset] => utf-8[gzipcompress] => 0[cookiepre] => uchome_  [cookiedomain] =>     //cookie域名[cookiepath] => /     //cookie路径[attachdir] => ./attachment/   上传图片新地址[attachurl] => attachment/[siteurl] => http://127.0.0.1:911/uchome/[tplrefresh] => 0  //刷新[founder] => 1   //创始人[allowedittpl] => 0 //)

$_SCONFIG：个人空间配置

函数读取的是缓存中data_config文件中的信息，如果不存在本文件则调用souce中的函数文件function_cache重新写入一个data缓存文件，然后调用，本函数读取的数据库是config文件是数据库

举例说明：

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="$value[fieldid]"onclick="fieldselect(this.value)"><labelfor="fieldid_$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 $value}--><!--{evalif(!($_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)"><labelfor="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。

管理员新建群组界面

而普通会员登录后，新建群组只能选个别分类。

以上为个人实践的总结，如有不对之处，敬请指出！
