  • 织梦dede整合discuz后会员注册后不用激活实现方法

    下面说下dedecms整合discuz后会员注册后不用激活的实现,以前做站时,一直在想,dede和dz整合后,会员在网站注册后到论坛能不能不再激活,看着可不舒服,现在总算解决了,闲话不说了,下面进入正题,百度也不让发附件,只有啰嗦点了,呵呵,比较长,分3篇:
    1.首先找到dede-〉api-〉uc.php文件
    打开uc.php,将内容替换为:

    <?php
    /**************************二次开发说明**************************************

    此模块应用于DEDECMS5.7版本,请替换API文件夹的UC.PHP,替换后,通过DEDE注册的用户,
    访问论坛系统可以免激活,实现同时登陆同时退出。
