Discuz x3.2昵称功能修改

思路：
尽可能少的改动文件(模板及其他相关文件)
common_member表中,新加一个字段loginname,用来代替原来的username
common_member表中原username当成昵称使用
改动相关注册和登录逻辑,即可实现,尽最大程序减少模板等相关文件修改

一、SQL修改记录

	ALTER TABLE pre_common_member ADD COLUMN loginname char(15) NOT NULL;
	UPDATE pre_common_member SET loginname=username;
	UPDATE pre_common_member SET username=nickname;		
	ALTER TABLE `pre_common_member` ADD INDEX loginname(`loginname`);

二、登录逻辑修改

M uc_client/model/user.php : function get_user_by_boyuan(…)

1.修改common_member相关操作中,username变为昵称
2.新增loginname字段,使用原username的值

    //原username当成昵称使用,新增loginname字段用来登录
        $row = DB::fetch_first("SELECT * FROM ".DB::table('common_member')." WHERE loginname='$username'");
        if ( isset($row['uid']) ) return $row;

        DB::insert('common_member', array(
            'uid'        => $uid,
            'username'   => $response->NickName,
            'loginname'   => $username,
            'password'   => md5($password),
            'email'      => $username,
            'adminid'    => 0,
            'groupid'    => 10,
            'regdate'    => TIMESTAMP,
            'credits'    => 5,
            'timeoffset' => 9999,
            'nickname'   => $response->NickName,
        ));

三、注册逻辑修改

M source/class/class_member.php : function on_register()

1.增加nickname

    $nickname = isset($_GET['field1']) ? trim($_GET['field1']) : '';
    $nickname = addslashes(dhtmlspecialchars($nickname));

2.昵称重复检查

    if(C::t('common_member')->fetch_uid_by_nickname($nickname)) {
        if($_G['inajax']) {
            showmessage('profile_nickname_duplicate');
        } else {
            showmessage('register_activation_message', 'member.php?mod=logging&action=login', array('username' => $username));
        }    
    }

3.向common_member注册时传入参数,增加nickname

    //注册传入nickname参数
    $init_arr = array('credits' => explode(',', $this->setting['initcredits']), 'profile'=>$profile, 'emailstatus' => $emailstatus,'nickname'=>$nickname);

M source/class/table/table_common_member.php

1.修改 fetch_uid_by_username(){},变更字段username->loginname

    public function fetch_uid_by_username($username, $fetch_archive = 0) {
        $uid = 0;
        if($username) {
            $uid = DB::result_first('SELECT uid FROM %t WHERE loginname=%s', array($this->_table, $username));
            if(isset($this->membersplit) && $fetch_archive && empty($uid)) {
                $uid = C::t($this->_table.'_archive')->fetch_uid_by_username($username, 0); 
            }   
        }   
        return $uid;
    }

2.新增 fetch_uid_by_nickname(){}

     public function fetch_uid_by_nickname($nickname, $fetch_archive = 0) {
        $uid = 0;
        if($nickname) {
            $uid = DB::result_first('SELECT uid FROM %t WHERE username=%s', array($this->_table, $nickname));
            if(isset($this->membersplit) && $fetch_archive && empty($uid)) {
                $uid = C::t($this->_table.'_archive')->fetch_uid_by_username($username, 0); 
            }   
        }   
        return $uid;
    }

3.修改insert(){}
$nickname = isset($extdata[‘nickname’]) ? $extdata[‘nickname’] : ‘’;
‘username’ => (string)$nickname,
‘loginname’ => (string)$username,

 public function insert($uid, $username, $password, $email, $ip, $groupid, $extdata, $adminid = 0) {
        if(($uid = dintval($uid))) {
            $nickname = isset($extdata['nickname']) ? $extdata['nickname'] : '';
            $credits = isset($extdata['credits']) ? $extdata['credits'] : array();
            $profile = isset($extdata['profile']) ? $extdata['profile'] : array();
            $profile['uid'] = $uid;
            $base = array(
                'uid' => $uid,
                'username' => (string)$nickname,
                'loginname' => (string)$username,
                'password' => (string)$password,
                'email' => (string)$email,
                .....
