PHP网页游戏学习之Xnova(ogame)源码解读(四)
这篇文章主要介绍了PHP网页游戏Xnova(ogame)源码解读的用户登录页面,需要的朋友可以参考下
五、 用户登录(login.php)
在开始的时候,我们说过游戏的入口是index.php文件;我们已经安装好了,自然转向登录流程,开始看。
前面照例是一段我们前进介绍过的代码,我们就不再详细讲了;不同的是使用的语言文件是login.mo,还有一个LOGIN的常量。如下
define('INSIDE' , true); define('INSTALL' , false); define('LOGIN' , true); $InLogin = true; $xnova_root_path = './'; include($xnova_root_path . 'extension.inc'); include($xnova_root_path . 'common.' . $phpEx); includeLang('login');
接下来又是我们前面讲过的结构,我们看初次进入的分支是下面代码:
$parse = $lang; $Count = doquery('SELECT COUNT(*) as `players` FROM {{table}} WHERE 1', 'users', true); $LastPlayer = doquery('SELECT `username` FROM {{table}} ORDER BY `register_time` DESC', 'users', true); $parse['last_user'] = $LastPlayer['username']; $PlayersOnline = doquery("SELECT COUNT(DISTINCT(id)) as `onlinenow` FROM {{table}} WHERE `onlinetime` > '" . (time()-900) ."';", 'users', true); $parse['online_users'] = $PlayersOnline['onlinenow']; $parse['users_amount'] = $Count['players']; $parse['servername'] = $game_config['game_name']; $parse['forum_url'] = $game_config['forum_url']; $parse['PasswordLost'] = $lang['PasswordLost']; $page = parsetemplate(gettemplate('login_body'), $parse); // Test pour prendre le nombre total de joueur et le nombre de joueurs connect閟 if ($_GET['ucount'] == 1) { $page = $PlayersOnline['onlinenow']."/".$Count['players']; die ( $page ); } else { display($page, $lang['Login']); }
主要是取得注册用户数、最后注册用户、当前在线数;并显示登陆欢迎页面,包括前面取得的这些用户数据。
好了,现在用户可以选择注册并转向前面章节流程,或者是输入用户名和密码转入登录流程。
1. 先根据输入的用户,从数据库取得此用户的记录
2. 如果有记录,则使用md5判断用户的密码是否正确
3. 如果密码正确,则看用户是否选择了记住密码功能,后面用到
4. include数据库配置文件config
5. Setcookie,里面有用户名、密码等
6. 重定向到frames.php文件
其中前面的几个判断是否的话,就要出现一些错误提示信息,并结束登录过程,使用的是message()函数提示,,前面也讲过。
