discuz论坛 用户登录 后台程序代码_PHP教程

还好,用户登录这里通过一个小小的方法可以实现和论坛同步了.可以不用passport接口.
这是我整理的数据,仅供参考.
登录传两值过来就行(username和password);

代码如下:

<?php 
session_start(); 
define('NOROBOT', TRUE); 
define('CURSCRIPT', 'logging'); 
require_once './include/common.inc.php'; 
require_once DISCUZ_ROOT.'./include/misc.func.php'; 
if($action == 'login') { 
$field = $loginfield == 'uid' ? 'uid' : 'username'; 
//get secure code checking status (pos. -2) 
$seccodecheck = substr(sprintf('%05b', $seccodestatus), -2, 1); 
if($seccodecheck && $seccodedata['loginfailedcount']) { 
$seccodecheck = $db->result($db->query("SELECT count(*) FROM {$tablepre}failedlogins WHERE ip='$onlineip' AND count>='$seccodedata[loginfailedcount]' AND $timestamp-lastupdate<=900"), 0); 
} 
$discuz_uid = 0; 
$discuz_user = $discuz_pw = $discuz_secques = $md5_password = ''; 
$member = array(); 
$loginperm = logincheck(); 
if(!$loginperm) { 
showmessage('login_strike'); 
} 
$secques = quescrypt($questionid, $answer); 
if(isset($loginauth)) { 
$field = 'username'; 
$password = 'VERIFIED'; 
list($username, $md5_password) = daddslashes(explode("\t", authcode($loginauth, 'DECODE')), 1); 
} else { 
$md5_password = md5($password); 
$password = preg_replace("/^(.{".round(strlen($password) / 4)."})(.+?)(.{".round(strlen($password) / 6)."})$/s", "\\1***\\3", $password); 
} 
$query = $db->query("SELECT m.uid AS discuz_uid, m.username AS discuz_user, m.password AS discuz_pw, m.secques AS discuz_secques, 
m.adminid, m.groupid, m.styleid AS styleidmem, m.lastvisit, m.lastpost, u.allowinvisible 
FROM {$tablepre}members m LEFT JOIN {$tablepre}usergroups u USING (groupid) 
WHERE m.$field='$username'"); 
$member = $db->fetch_array($query); 
//判断登录是否正确 
if($member['password']!=$md5_password){ 
echo "您输入的用户名或密码错误!"; 
exit(); 
} 
//通过就执行下边的程序 
extract($member); 
$discuz_userss = $discuz_user; 
$discuz_user = addslashes($discuz_user); 
if(($allowinvisible && $loginmode == 'invisible') || $loginmode == 'normal') { 
$db->query("UPDATE {$tablepre}members SET invisible='".($loginmode == 'invisible' ? 1 : 0)."' WHERE uid='$member[discuz_uid]'", 'UNBUFFERED'); 
} 
$styleid = intval(empty($_POST['styleid']) ? ($styleidmem ? $styleidmem : 
$_DCACHE['settings']['styleid']) : $_POST['styleid']); 
$cookietime = intval(isset($_POST['cookietime']) ? $_POST['cookietime'] : 
($_DCOOKIE['cookietime'] ? $_DCOOKIE['cookietime'] : 0)); 
dsetcookie('cookietime', $cookietime, 31536000); 
dsetcookie('auth', authcode("$discuz_pw\t$discuz_secques\t$discuz_uid", 'ENCODE'), $cookietime); 
$sessionexists = 0; 
updatesession();//更新论坛USERPASS数据 
echo "{'action':'ture'}";//这里是您要输出的数据 
print_r($_DSESSION); 
echo $discuz_userss; 
} 
?>
