Discuz X2.5注册用户名突破15字节的修改方法

以下代码中的数值3改成自己想要的最小长度如1，15改成自己想要的最大长度如40

1、uc_client\model\user.php

if($$$$len > 15 || $$$$len < 3 || preg_match("/\s+|^c:\\con\\con|[%,\*\"\s\<\>\&]|$$$$guestexp/is", $$$$username))

2、template\default\member\register.htm

<input type="text" id="{$$$$this->setting['reginput']['username']}" name="" class="px" tabindex="1" autocomplete="off" size="25" maxlength="15" required />

3、source\language\member\lang_template.php

4、static\js\register.js

5、source\class\class_member.php

6、source/module/forum/forum_ajax.php

if($$$$usernamelen < 3) {
showmessage('profile_username_tooshort', '', array(), array('handle' => false));
} elseif($$$$usernamelen > 15) {

7、升级数据库(只对关键字段进行升级，基本满足正常使用了)，本例中最大长度修改为40

ALTER TABLE `pre_common_member` CHANGE `username` `username` CHAR( 40 ) ;
ALTER TABLE `pre_home_blog` CHANGE `username` `username` CHAR( 40 ) ;
ALTER TABLE `pre_ucenter_members` CHANGE `username` `username` CHAR( 40 ) ;
ALTER TABLE `pre_ucenter_mergemembers` CHANGE `username` `username` CHAR( 40 ) ;
ALTER TABLE `pre_ucenter_feeds` CHANGE `username` `username` CHAR( 40 ) ;
ALTER TABLE `pre_forum_post` CHANGE `author` `author` CHAR( 40 ) ;
ALTER TABLE `pre_forum_thread` CHANGE `author` `author` CHAR( 40 ) ;
ALTER TABLE `pre_home_album` CHANGE `username` `username` CHAR( 40 ) ;
ALTER TABLE `pre_forum_announcement` CHANGE `author` `author` CHAR( 40 ) ;
ALTER TABLE `pre_forum_groupuser` CHANGE `username` `username` CHAR( 40 ) ;
