discuz外部登录PHP代码
度娘告知的外部登录discuz的代码大多都是用post进行提交，然后是定时刷新实现登录，度娘中比较满意的是一个点击弹出登录框代码
直接JS调用弹出登录框，注册框，和找回密码，登录框和注册框提交之后都可以返回到首页，找回密码返回到的是论坛，可能需要修改下模版文件吧
<a href="javascript:;" onclick="showWindow('login', 'member.php?mod=logging&action=login');hideWindow('register'); ">登录</a>
<a href="javascript:;" onclick="showWindow('register', 'member.php?mod=register');hideWindow('login');">注册</a>
<a href="javascript:;" onclick="showWindow('login', 'member.php?mod=logging&action=login&viewlostpw');hideWindow('register'); ">找回密码</a>另外一个就是有输入框的代码，这个是直接从Discuz论坛上直接抠下来的代码，应该是ajax提交判断
登录的时候无刷新更新
代码，直接从源码那里抠下来的

</table>
<input type="hidden" name="quickforward" value="yes" />
<input type="hidden" name="handlekey" value="ls" />
</form>实现登录功能，以上两种都是直接登录论坛的，和整合的应该不大一样吧。
获取登录用户信息可以用class_core.php，代码：
require './source/class/class_core.php';
$discuz = & discuz_core::instance();//以下代码为创建及初始化对象
$discuz->cachelist = $cachelist;
$discuz->init();//以上是调用discuz公共执行类等核心代码
//$_G['username'];信息量很多的，可以慢慢找！
