整合 ucenter 注册自动激活

应用整合 UCenter，同步注册到 Discuz 的用户，在 Discuz 登录时得手动激活，用户体验很不好，不过解决方法很简单~

修改应用下的 ./uc_client/model/user.php 文件，大概在 138 行（UCenter 1.6）处的 function add_user 函数里添加代码：

function add_user($username, $password, $email, $uid = 0, $questionid = '', $answer = '', $regip = '') {
	$regip = empty($regip) ? $this->base->onlineip : $regip;
	$salt = substr(uniqid(rand()), -6);
	$password = md5(md5($password).$salt);
	$sqladd = $uid ? "uid='".intval($uid)."'," : '';
	$sqladd .= $questionid > 0 ? " secques='".$this->quescrypt($questionid, $answer)."'," : " secques='',";
	$this->db->query("INSERT INTO ".UC_DBTABLEPRE."members SET $sqladd username='$username', password='$password', email='$email', regip='$regip', regdate='".$this->base->time."', salt='$salt'");
	$uid = $this->db->insert_id();
	$this->db->query("INSERT INTO ".UC_DBTABLEPRE."memberfields SET uid='$uid'");
	// BEGIN
	$this->db->query("INSERT INTO ".DISCUZ_DBTABLEPRE."common_member SET uid='$uid', username='$username', password='$password', email='$email', adminid='0', groupid='10', regdate='".$this->base->time."', credits='0', timeoffset='9999'");
	$this->db->query("INSERT INTO ".DISCUZ_DBTABLEPRE."common_member_status SET uid='$uid', regip='$regip', lastip='$regip', lastvisit='".$this->base->time."', lastactivity='".$this->base->time."', lastpost='0', lastsendmail='0'");
	$this->db->query("INSERT INTO ".DISCUZ_DBTABLEPRE."common_member_profile SET uid='$uid'");
	$this->db->query("INSERT INTO ".DISCUZ_DBTABLEPRE."common_member_field_forum SET uid='$uid'");
	$this->db->query("INSERT INTO ".DISCUZ_DBTABLEPRE."common_member_field_home SET uid='$uid'");
	$this->db->query("INSERT INTO ".DISCUZ_DBTABLEPRE."common_member_count SET uid='$uid', extcredits1='0', extcredits2='0', extcredits3='0', extcredits4='0', extcredits5='0', extcredits6='0', extcredits7='0', extcredits8='0'");
	// END
	return $uid;
}

注意这些表都是 Discuz 的表，不是 UCenter 的表，不能使用 UC_DBTABLEPRE ！ 我自己在 UCenter 配置文件 config.inc.php 中定义了 DISCUZ_DBTABLEPRE：

define('DISCUZ_DBTABLEPRE', '`ultrax`.pre_');
