discuz论坛整合ucenter免激活，同步登录，同步退出解决方案一、discuzX1.5免激活修改步骤： 
1． 注册完成插入数据库后，进行同步登录 
修改文件upload\source\module\member\member_register.php 

$_G['setting']['lastmember'] = $username; 
save_syscache(‘setting’, $_G['setting']); 
$_G['setting']['regverify'] = $regverify; 
$ucsynlogin = $_G['setting']['allowsynlogin'] ? uc_user_synlogin($_G['uid']) : ”; //进行UC同步登录，注册免激活 
if(!empty($_G['inajax'])) { 
$_G['setting']['msgforward'] = unserialize($_G['setting']['msgforward']); 
$mrefreshtime = intval($_G['setting']['msgforward']['refreshtime']) * 1000; 
if(!empty($_G['inajax'])) { 
include template(‘member/register’); 
} else { 
showmessage(‘profile_email_verify’, ”, $param, array(‘extrajs’ => $ucsynlogin)); //输出同步登录的UC代码 
} 
break; 
case 2: 
showmessage(‘register_manual_verify’, ‘home.php?mod=space&do=home’, $param, array(‘extrajs’ => $ucsynlogin)); //输出同步登录的UC代码 
break; 
default: 
showmessage(‘register_succeed’, dreferer(), $param, array(‘extrajs’ => $ucsynlogin)); ////输出同步登录的UC代码 

2． 修改\upload\template\default\member \register.htm 

<!–{template common/header}–> 
<!–{if !empty($message)}–> 
$ucsynlogin //添加输出UC同步登录代码 

3． 修改upload\api\uc.php 
修改方法function synlogin($get, $post) { 
{ 
If{ 
} 
Else{ 
添加免激活代码，源代码看文件 
} 
}
