Ucenter注册后，需要二次登录才能同步登录的解决方案

1.

打开配置文件config.inc.php 在根目录data目录下
最下方定义 define('DZ_DBTABLEPRE', '你的表前缀');    

2.打开uc_server/model/user.php  add_user函数
 在retun之前加入以下代码

// BEGIN
        $this->db->query("INSERT INTO ".DZ_DBTABLEPRE."common_member SET uid='$uid', username='$username', password='$password', email='$email', adminid='0', groupid='10', regdate='".$this->base->time."', credits='0', timeoffset='9999'");
        $this->db->query("INSERT INTO ".DZ_DBTABLEPRE."common_member_status SET uid='$uid', regip='$regip', lastip='$regip', lastvisit='".$this->base->time."', lastactivity='".$this->base->time."', lastpost='0', lastsendmail='0'");
        $this->db->query("INSERT INTO ".DZ_DBTABLEPRE."common_member_profile SET uid='$uid', realname='$real'");
        $this->db->query("INSERT INTO ".DZ_DBTABLEPRE."common_member_field_forum SET uid='$uid'");
        $this->db->query("INSERT INTO ".DZ_DBTABLEPRE."common_member_field_home SET uid='$uid'");
        $this->db->query("INSERT INTO ".DZ_DBTABLEPRE."common_member_count SET uid='$uid', extcredits1='0', extcredits2='0', extcredits3='0', extcredits4='0', extcredits5='0', extcredits6='0', extcredits7='0', extcredits8='0'");
        // END
