Discuz home模块解析
功能解析home模块很庞大，包含了discuz社区和用户信息相关的几乎所有功能，比如动态、消息、勋章、道具等等，有的功能还分为很多小功能，下面列出home模块基本的组成：
子模块
说明
space
用户个人空间相关的功能，如活动、相册、日志、收藏、好友、分享、悬赏等等
spacecp
用户个人空间相关功能的改动，如添加好友、发日志、收藏帖子等等
misc
magic道具相关
editor
编辑器
invite
邀请相关
task
任务相关，如任务列表、申请任务、获取奖励、放弃任务等功能
medal
勋章相关，如勋章列表、申请勋章等功能
rss
网站信息聚合页
follow
广播相关
下面分别分析home模块的各个子模块：
rss模块
访问连接:home.php?mod=rss
此处的rss应该是指Really Simple Syndication(简易信息聚合)，输出网站的信息和对应用户的个人动态信息（blog）：
//输出网站信息echo "<?xml version="1.0" encoding="".$charset.""?>\n"."<rss version="2.0">\n"."<channel>\n"." <title>{$space}</title>\n"." <link>{$space}</link>\n"." <description>{$_G}</description>\n"." <copyright>Copyright(C) {$_G}</copyright>\n"." <generator>Discuz! Board by Comsenz Inc.</generator>\n"." <lastBuildDate>".gmdate('r', TIMESTAMP)."</lastBuildDate>\n"." <image>\n"." <url>{$_G}static/image/common/logo_88_31.gif</url>\n"." <title>{$_G}</title>\n"." <link>{$_G}</link>\n"." </image>\n";//输出用户个人动态，$data_blog是根据uid在home_blog表中获取的//$data_blog = C::t('home_blog')->range(0, $pagenum, 'DESC', 'dateline', 0, null, $uid);foreach($data_blog as $curblogid => $value) {$value = array_merge($value, (array)$data_blogfield[$curblogid]);$value['message'] = getstr($value['message'], 300, 0, 0, 0, -1);if($value['pic']) {$value['pic'] = pic_cover_get($value['pic'], $value['picflag']);$value['message'] .= "<br /><img src="$value">";}echo " <item>\n"." <title>".$value['subject']."</title>\n"." <link>$_Ghome.php?mod=space&uid=$value&do=blog&id=$value</link>\n"." <description><!)."]]></description>\n"." <author>".dhtmlspecialchars($value['username'])."</author>\n"." <pubDate>".gmdate('r', $value['dateline'])."</pubDate>\n"." </item>\n";}echo "</channel>\n"."</rss>";
medal模块
访问连接:home.php?mod=medal
medal模块即勋章模块，这个模块分别有以下几个功能（对应到action字段）：
action
功能
action为空的情况下显示所有可用勋章列表log
显示我的勋章列表
confirm
显示申请勋章窗口
apply
确认申请勋章
进入medal模块，就有一句缓存相关的调用，从common_syscache表中取出medals的缓存并存入全局变量$_G[‘cache’][$cachename]中，以便取用。
loadcache('medals');
展示所有勋章
展示所有勋章的代码如下，我添加了注释说明：
include libfile('function/forum');$medalcredits = array();//在forum_medal表中获取所有勋章并遍历foreach(C::t('forum_medal')->fetch_all_data(1) as $medal) {//勋章获取权限，如金钱>100、威望>100等$medal['permission'] = medalformulaperm(serialize(array('medal' => dunserialize($medal['permission']))), 1);//勋章也可设置为可使用积分、威望等值购买if($medal['price']) {$medal['credit'] = $medal['credit'] ? $medal['credit'] : $_G['setting']['creditstransextra'];$medalcredits[$medal['credit']] = $medal['credit'];}$medallist[$medal['medalid']] = $medal;}//在common_member_field_forum表中获取当前用户已获得的勋章列表$memberfieldforum = C::t('common_member_field_forum')->fetch($_G['uid']);$membermedal = $memberfieldforum['medals'] ? explode("\t", $memberfieldforum['medals']) : array();$membermedal = array_map('intval', $membermedal);$lastmedals = $uids = array();//在forum_medallog表中获取最后10条勋章发放/获取记录foreach(C::t('forum_medallog')->fetch_all_lastmedal(10) as $id => $lastmedal) {$lastmedal['dateline'] = dgmdate($lastmedal['dateline'], 'u');$lastmedals[$id] = $lastmedal;$uids[] = $lastmedal['uid'];}//获取最后10条勋章发放记录相关用户的信息$lastmedalusers = C::t('common_member')->fetch_all($uids);//获取当前登录用户已获得的所有勋章列表，此处的勋章列表和前面的变量$membermedal重复了，暂时不知道二者的区别$mymedals = C::t('common_member_medal')->fetch_all_by_uid($_G['uid']);log–我的勋章
我的勋章列表的实现代码与展示所有勋章的实现代码基本一致，唯一不同的就是勋章获取记录显示的是个人的记录，所以此处就不展开分析了。
comfirm–申请勋章窗口
include libfile('function/forum');//获取所有勋章列表$medal = C::t('forum_medal')->fetch($_GET['medalid']);//获取勋章权限和价格$medal['permission'] = medalformulaperm(serialize(array('medal' => dunserialize($medal['permission']))), 1);if($medal['price']) {$medal['credit'] = $medal['credit'] ? $medal['credit'] : $_G['setting']['creditstransextra'];$medalcredits[$medal['credit']] = $medal['credit'];}include template('home/space_medal_float');
confirm功能通过上面的代码获取勋章的详细信息，并通过下面的js代码以窗口的形式展示：
onclick="showWindow('medal', 'home.php?mod=medal&action=confirm&medalid=7')"
apply–提交申请
提交申请的实现代码大致如下，在注释里分析其实现：
$medalid = intval($_GET['medalid']);$_G['forum_formulamessage'] = $_G['forum_usermsg'] = $medalnew = '';//获取所有可用的勋章列表$medal = C::t('forum_medal')->fetch($medalid);//检查勋章是否可申请if(!$medal['type']) {showmessage('medal_apply_invalid');}//检查是否已持有勋章if(C::t('common_member_medal')->count_by_uid_medalid($_G['uid'], $medalid)) {showmessage('medal_apply_existence', 'home.php?mod=medal');}$applysucceed = FALSE;//是否符合申请条件$medalpermission = $medal['permission'] ? dunserialize($medal['permission']) : '';//检查勋章是否有用户组限制if($medalpermission || $medalpermission['usergroupallow']) {include libfile('function/forum');medalformulaperm(serialize(array('medal' => $medalpermission)), 1);if($_G['forum_formulamessage']) {showmessage('medal_permforum_nopermission', 'home.php?mod=medal', array('formulamessage' => $_G['forum_formulamessage'], 'usermsg' => $_G['forum_usermsg']));} else {$applysucceed = TRUE;}} else {$applysucceed = TRUE;}if($applysucceed) {$expiration = empty($medal['expiration'])? 0 : TIMESTAMP + $medal['expiration'] * 86400;if($medal['type'] == 1) {//勋章类型为可购买if($medal['price']) {//勋章是否需要花积分或威望等值购买//积分或威望是否足够$medal['credit'] = $medal['credit'] ? $medal['credit'] : $_G['setting']['creditstransextra'];if($medal['price'] > getuserprofile('extcredits'.$medal['credit'])) {showmessage('medal_not_get_credit', '', array('credit' => $_G['setting']['extcredits'][$medal]));}//扣除购买积分或威望等updatemembercount($_G['uid'], array($medal['credit'] => -$medal['price']), true, 'BME', $medal['medalid']);}$memberfieldforum = C::t('common_member_field_forum')->fetch($_G['uid']);$usermedal = $memberfieldforum;unset($memberfieldforum);$medal['medalid'] = $medal['medalid'].(empty($expiration) ? '' : '|'.$expiration);$medalnew = $usermedal['medals'] ? $usermedal['medals']."\t".$medal['medalid'] : $medal['medalid'];//给当前用户添加购买的勋章C::t('common_member_field_forum')->update($_G['uid'], array('medals' => $medalnew));C::t('common_member_medal')->insert(array('uid' => $_G['uid'], 'medalid' => $medal['medalid']), 0, 1);$medalmessage = 'medal_get_succeed';} else {//勋章类型为其他可申请的类型//检查是否已经申请过了if(C::t('forum_medallog')->count_by_verify_medalid($_G['uid'], $medal['medalid'])) {showmessage('medal_apply_existence', 'home.php?mod=medal');}$medalmessage = 'medal_apply_succeed';//通知管理员审核勋章manage_addnotify('verifymedal');}//记录勋章申请请求C::t('forum_medallog')->insert(array('uid' => $_G['uid'],'medalid' => $medalid,'type' => $medal['type'],'dateline' => TIMESTAMP,'expiration' => $expiration,'status' => ($expiration ? 1 : 0),));showmessage($medalmessage, 'home.php?mod=medal', array('medalname' => $medal['name']));}
task模块
discuz自带任务模块，可在discuz管理中心->运营->站点任务中开启任务模块并管理社区任务。
任务模块主要有以下几个功能，请求的字段do的值代表功能：
do值
功能
当do字段值为空时，表示浏览任务列表view
查看任务详情
apply
申请任务
delete
放弃任务
draw
领取奖励
giveup
放弃任务，功能与delete一样，暂时未知被哪里调用
parter
参与某任务的用户列表
任务模块的业务逻辑实现主要在/source/class/class_task.php中，其数据存储主要跟表common_task、common_mytask和common_taskvar表相关。
数据库表
描述
common_task
存储所有社区任务
common_mytask
存储所有用户和任务的关系
common_taskvar
存储任务的详细信息
展示任务列表
获取任务列表的功能代码如下，我将在注释中解析功能：
function tasklist($item) {...//从数据库中获取与用户和item相关的任务列表，item有4个值new/doing/done/failed分别对应新任务、进行中任务、已完成任务和失败任务foreach(C::t('common_task')->fetch_all_by_status($_G['uid'], $item) as $task) {//从fetch_all_by_status方法中看，new和canapply没有区别if($item == 'new' || $item == 'canapply') {//检查任务的时间限制list($task['allowapply'], $task['t']) = $this->checknextperiod($task);if($task['allowapply'] < 0) {//不符合时间限制则不显示任务continue;}$task['noperm'] = $task['applyperm'] && $task['applyperm'] != 'all' && !(($task['applyperm'] == 'member'&& $_G['adminid'] == '0') || ($task['applyperm'] == 'admin' && $_G['adminid'] > '0') || forumperm($task['applyperm']));$task['appliesfull'] = $task['tasklimits'] && $task['achievers'] >= $task['tasklimits'];//不符合权限限制和已申请满员则不显示任务if($item == 'canapply' && ($task['noperm'] || $task['appliesfull'])) {continue;}}$num++;//任务的奖励类型if($task['reward'] == 'magic') {$magicids[] = $task['prize'];} elseif($task['reward'] == 'medal') {$medalids[] = $task['prize'];} elseif($task['reward'] == 'invite') {$invitenum = $task['prize'];} elseif($task['reward'] == 'group') {$groupids[] = $task['prize'];}//任务已启用且在可申请时间内if($task['available'] == '2' && ($task['starttime'] > TIMESTAMP || ($task['endtime'] && $task['endtime'] <= TIMESTAMP))) {$endtaskids[] = $task['taskid'];}//csc字段包含了任务进度百分比和最后更新时间，用\t隔开$csc = explode("\t", $task['csc']);$task['csc'] = floatval($csc);//获取任务进度$task['lastupdate'] = intval($csc);//获取任务进度更新时间//更新任务进度if(!$updated && $item == 'doing' && $task['csc'] < 100) {$updated = TRUE;$escript = explode(':', $task['scriptname']);//discuz支持任务插件，插件任务存在/source/plugin/中，原生任务在/source/class/task/中if(count($escript) > 1) {include_once DISCUZ_ROOT.'./source/plugin/'.$escript.'/task/task_'.$escript.'.php';$taskclassname = 'task_'.$escript;} else {require_once libfile('task/'.$task['scriptname'], 'class');$taskclassname = 'task_'.$task['scriptname'];}$taskclass = new $taskclassname;$task['applytime'] = $task['dateline'];if(method_exists($taskclass, 'csc')) {$result = $taskclass->csc($task);//计算任务进度} else {showmessage('task_not_found', '', array('taskclassname' => $taskclassname));}//更新用户和任务的关系if($result === TRUE) {$task['csc'] = '100';C::t('common_mytask')->update($_G['uid'], $task['taskid'], array('csc' => $task['csc']));} elseif($result === FALSE) {C::t('common_mytask')->update($_G['uid'], $task['taskid'], array('status' => -1));} else {$task['csc'] = floatval($result['csc']);C::t('common_mytask')->update($_G['uid'], $task['taskid'], array('csc' => $task['csc']."\t".$_G['timestamp']));}}//如果该任务已完成或者已失败，检查是否可重新申请if(in_array($item, array('done', 'failed')) && $task['period']) {list($task['allowapply'], $task['t']) = $this->checknextperiod($task);$task['allowapply'] = $task['allowapply'] > 0 ? 1 : 0;}//获取任务图标$task['icon'] = $task['icon'] ? $task['icon'] : 'task.gif';if(strtolower(substr($task['icon'], 0, 7)) != 'http://') {$escript = explode(':', $task['scriptname']);if(count($escript) > 1 && file_exists(DISCUZ_ROOT.'./source/plugin/'.$escript.'/task/task_'.$escript.'.gif')) {$task['icon'] = 'source/plugin/'.$escript.'/task/task_'.$escript.'.gif';} else {$task['icon'] = 'static/image/task/'.$task['icon'];}}$task['dateline'] = $task['dateline'] ? dgmdate($task['dateline'], 'u') : '';$tasklist[] = $task;}//根据任务奖励类型获取奖励相关的信息//获取奖励物品名if($magicids) {foreach(C::t('common_magic')->fetch_all($magicids) as $magic) {$this->listdata[$magic['magicid']] = $magic['name'];}}//获取奖励奖章名if($medalids) {foreach(C::t('forum_medal')->fetch_all($medalids) as $medal) {$this->listdata[$medal['medalid']] = $medal['name'];}}//获取奖励用户组名if($groupids) {foreach(C::t('common_usergroup')->fetch_all($groupids) as $group) {$this->listdata[$group['groupid']] = $group['grouptitle'];}}//获取奖励邀请码if($invitenum) {$this->listdata[$invitenum] = $_G['lang']['invite_code'];}//无奖励if($endtaskids) {}return $tasklist;}
view–任务详情
任务详情的代码如下：
function view($id) {//获取任务信息$this->task = C::t('common_task')->fetch_by_uid($_G['uid'], $id);...//获取任务奖励信息switch($this->task['reward']) {case 'magic':$this->task['rewardtext'] = C::t('common_magic')->fetch($this->task['prize']);$this->task['rewardtext'] = $this->task['rewardtext']['name'];break;case 'medal':$this->task['rewardtext'] = C::t('forum_medal')->fetch($this->task['prize']);$this->task['rewardtext'] = $this->task['rewardtext']['name'];break;case 'group':$group = C::t('common_usergroup')->fetch($this->task['prize']);$this->task['rewardtext'] = $group['grouptitle'];break;}//获取任务图标链接$this->task['icon'] = $this->task['icon'] ? $this->task['icon'] : 'task.gif';if(strtolower(substr($this->task['icon'], 0, 7)) != 'http://') {$escript = explode(':', $this->task['scriptname']);if(count($escript) > 1 && file_exists(DISCUZ_ROOT.'./source/plugin/'.$escript.'/task/task_'.$escript.'.gif')) {$this->task['icon'] = 'source/plugin/'.$escript.'/task/task_'.$escript.'.gif';} else {$this->task['icon'] = 'static/image/task/'.$this->task['icon'];}}//获取任务结束时间和任务描述$this->task['endtime'] = $this->task['endtime'] ? dgmdate($this->task['endtime'], 'u') : '';$this->task['description'] = nl2br($this->task['description']);$this->taskvars = array();foreach(C::t('common_taskvar')->fetch_all_by_taskid($id) as $taskvar) {if(!$taskvar['variable'] || $taskvar['value']) {if(!$taskvar['variable']) {$taskvar['value'] = $taskvar['description'];}//用户相对该任务的状态if($taskvar['sort'] == 'apply') {$this->taskvars['apply'][] = $taskvar;} elseif($taskvar['sort'] == 'complete') {$this->taskvars['complete'][$taskvar['variable']] = $taskvar;} elseif($taskvar['sort'] == 'setting') {$this->taskvars['setting'][$taskvar['variable']] = $taskvar;}}}//获取允许申请任务的用户组信息$this->task['grouprequired'] = $comma = '';$this->task['applyperm'] = $this->task['applyperm'] == 'all' ?

apply–申请任务
apply的申请流程如下：
function apply($id) {//获取任务信息$this->task = C::t('common_task')->fetch($id);//检查任务状态，字面意思就能看懂if($this->task['available'] != 2) {showmessage('task_nonexistence');} elseif(($this->task['starttime'] && $this->task['starttime'] > TIMESTAMP) || ($this->task['endtime'] && $this->task['endtime'] <= TIMESTAMP)) {showmessage('task_offline');} elseif($this->task['tasklimits'] && $this->task['achievers'] >= $this->task['tasklimits']) {showmessage('task_full');}if($this->task['relatedtaskid'] && !C::t('common_mytask')->count($_G['uid'], $this->task['relatedtaskid'], 1)) {//未完成关联任务return -1;} elseif($this->task['applyperm'] && $this->task['applyperm'] != 'all' && !(($this->task['applyperm'] == 'member' && $_G['adminid'] == '0') || ($this->task['applyperm'] == 'admin' && $_G['adminid'] > '0') || preg_match("/(^|\t)(".$_G['groupid'].")(\t|$)/", $this->task['applyperm']))) {//不符合申请权限return -2;} elseif(!$this->task['period'] && C::t('common_mytask')->count($_G['uid'], $id)) {//不允许多次申请任务return -3;} elseif($this->task['period']) {//检查申请时间和申请次数等限制$mytask = C::t('common_mytask')->fetch($_G['uid'], $id);$task = C::t('common_task')->fetch($id);$mytask['period'] = $task['period'];$mytask['periodtype'] = $task['periodtype'];unset($task);list($allowapply) = $this->checknextperiod($mytask);if($allowapply < 0) {return -4;}}...$taskclass = new $taskclassname;//检查其他条件if(method_exists($taskclass, 'condition')) {$taskclass->condition();}//申请成功，保存用户申请数据C::t('common_mytask')->insert(array('uid' => $_G['uid'],'username' => $_G['username'],'taskid' => $this->task['taskid'],'csc' => '0\t'.$_G['timestamp'],'dateline' => $_G['timestamp']), false, true);//申请用户数C::t('common_task')->update_applicants($this->task['taskid'], 1);if(method_exists($taskclass, 'preprocess')) {$taskclass->preprocess($this->task);}return true;}
delete,giveup–放弃任务
用户放弃任务的主要逻辑如下：
//移除用户和任务的关联C::t('common_mytask')->delete($_G['uid'], $id);//申请用户数减1C::t('common_task')->update_applicants($id, -1);
draw–领取奖励
领取奖励的主要逻辑如下：
function draw($id) {...} elseif($this->task['tasklimits'] && $this->task['achievers'] >= $this->task['tasklimits']) {//完成任务人数限制return -1;}...$taskclass = new $taskclassname;if(method_exists($taskclass, 'csc')) {$result = $taskclass->csc($this->task);//更新并获取任务进度} ...if($result === TRUE) {//任务已完成if($this->task['reward']) {//是否有奖励$rewards = $this->reward();$notification = $this->task['reward'];//获取任务奖励信息if($this->task['reward'] == 'magic') {$rewardtext = C::t('common_magic')->fetch($this->task['prize']);$rewardtext = $rewardtext['name'];} elseif($this->task['reward'] == 'medal') {$rewardtext = C::t('forum_medal')->fetch($this->task['prize']);$rewardtext = $rewardtext['name'];if(!$this->task['bonus']) {$notification = 'medal_forever';}} elseif($this->task['reward'] == 'group') {$group = C::t('common_usergroup')->fetch($this->task['prize']);$rewardtext = $group['grouptitle'];} elseif($this->task['reward'] == 'invite') {$rewardtext = $this->task['prize'];}//通知用户奖励信息notification_add($_G, 'task', 'task_reward_'.$notification, array('taskid' => $this->task['taskid'],'name' => $this->task['name'],'creditbonus' => $_G['setting']['extcredits'][$this->task['prize']]['title'].'

'.$_G['setting']['extcredits'][$this->task['prize']]['unit'],'rewardtext' => $rewardtext,'bonus' => $this->task['bonus'],'prize' => $this->task['prize'],));}//成功领取奖励的回调if(method_exists($taskclass, 'sufprocess')) {$taskclass->sufprocess($this->task);}//更新任务信息C::t('common_mytask')->update($_G['uid'], $id, array('status' => 1, 'csc' => 100, 'dateline' => $_G['timestamp']));C::t('common_task')->update_achievers($id, 1);...} elseif($result === FALSE) {//任务失败//更新任务状态C::t('common_mytask')->update($_G['uid'], $id, array('status' => -1));if($_G['inajax']) {$this->message('-1', 'task_failed');} else {return -2;}} else {//任务在执行中//提示任务进度$result['t'] = $this->timeformat($result['remaintime']);$this->messagevalues['values'] = array('csc' => $result['csc'], 't' => $result['t']);if($result['csc']) {C::t('common_mytask')->update($_G['uid'], $id, array('csc' => $result['csc']."\t".$_G['timestamp']));$this->messagevalues['msg'] = $result['t'] ? 'task_doing_rt' : 'task_doing';} else {$this->messagevalues['msg'] = $result['t'] ? 'task_waiting_rt' : 'task_waiting';}if($_G['inajax']) {$this->message($result['csc'], $this->messagevalues['msg'], $this->messagevalues['values']);} else {return -3;}}}
parter–参与者列表
获取参与者列表的主要实现如下：
function parter($id) {$parterlist = array();//最多抓取8位参与者信息foreach(C::t('common_mytask')->fetch_all_by_taskid($id, 8) as $parter) {//展示参与者头像、昵称和任务进度等信息$parter['avatar'] = avatar($parter['uid'], 'small');$csc = explode("\t", $parter['csc']);$parter['csc'] = floatval($csc);$parterlist[] = $parter;}return $parterlist;} 作为DZ插件网技术团队成员，我将针对Discuz! home模块的常见问题进行专业解析。以下是三个核心子模块的深度技术解决方案：
一、RSS模块异常排查方案
1. 数据源异常排查
检查home_blog表查询逻辑：
//确保UID有效性校验
$uid = intval($_GET['uid'] ?? 0);
if($uid > 0){
$data_blog = C::t('home_blog')->range(0, $pagenum, 'DESC', 'dateline', 0, null, $uid);
}
//建议增加缓存机制
$data_blog = memory('get', 'rss_feed_'.$uid);
if(!$data_blog){
$data_blog = C::t('home_blog')->range(...);
memory('set', 'rss_feed_'.$uid, $data_blog, 600);
}
2. 输出编码问题处理
修改XML头声明：
//原代码
echo "<?xml version=\"1.0\" encoding=\"".$_G['charset']."\"?>";
//强化编码处理
$charset = strtoupper($_G['charset']);
header("Content-Type: application/xml; charset=$charset");
echo "<?xml version=\"1.0\" encoding=\"$charset\"?>";
二、勋章模块常见故障处理
1. 勋章申请条件校验强化
//修改medalformulaperm函数调用方式
$medalpermission = dunserialize($medal['medalpermission']);
$permCheck = medalformulaperm(serialize(['medal' => $medalpermission]), 1);
//增加日志记录
if($_G['setting']['medallog']){
write_log('medal_apply', "UID:{$_G} 申请勋章ID:{$medalid} 校验结果:".json_encode($permCheck));
}
2. 勋章有效期计算优化
//原有效期计算
$expiration = $medal['expiration'] * 86400;
//修正为时间戳计算
$expiration = $medal['expiration'] > 0 ?
TIMESTAMP + ($medal['expiration'] * 86400) :
0;
//增加时区处理
$expiration += $_G['setting']['timeoffset'] * 3600;
三、任务系统深度优化方案
1. 任务进度更新机制
//强化csc方法容错处理
try {
$taskclass = new $taskclassname;
if(method_exists($taskclass, 'csc')){
$result = $taskclass->csc($task);
} else {
throw new Exception('csc方法不存在');
}
} catch(Exception $e){
log_task_error($e->getMessage());
$result = 0;
}
//增加进度验证
$progress = max(0, min(100, floatval($result)));
2. 任务奖励发放强化
//修改奖励发放逻辑
if($this->task['reward'] == 'medal' && $this->task['medalid']){
//增加勋章有效期绑定
C::t('common_member_medal')->insert([
'uid' => $_G['uid'],
'medalid' => $this->task['medalid'],
'expiration' => $expiration
], true);//开启重复检查
//同步更新medals字段
update_member_medal_cache($_G['uid']);
}
针对模块优化建议：
1. 缓存策略优化：
//在source/function/function_cache.php增加
function build_cache_medal(){
$data = C::t('forum_medal')->fetch_all();
savecache('medal', $data);
}
//调用示例
if(!$_G['cache']['medal']){
build_cache_medal();
}
2. 安全校验强化：
//在所有POST操作入口增加
$seccheck = security_confirm($_POST['formhash']);
if(!$seccheck){
showmessage('request_tainted');
}

- 自定义输出内容：可通过修改`source/module/home/home_rss.php`中的XML生成逻辑，添加自定义字段
- 增加聚合类型：在输出循环前加入新的数据查询，示例：
// 添加论坛帖子聚合
$forum_posts = C::t('forum_post')->fetch_all_by_authorid($uid);
foreach($forum_posts as $post) {
echo "<item>
<title>{$post['subject']}</title>
<link>forum.php?mod=viewthread&tid={$post['tid']}</link>
</item>";
}
2. 勋章系统深度定制方案：
（1）创建新型勋章类型：
// 在forum_medal表中新增字段
ALTER TABLE pre_forum_medal ADD COLUMN medal_type TINYINT(1) NOT NULL DEFAULT '0';
// 后台管理界面扩展
在source/admincp/admincp_medal.php的add/edit逻辑中增加类型选择
（2）动态勋章效果实现：
// 前端动态效果
Discuz.medalAnimation = function(medalId) {
$('.medal_'+medalId).hover(function(){
$(this).addClass('animated pulse');
}, function(){
$(this).removeClass('animated pulse');
});
};
3. 任务系统增强方案：
（1）创建多步骤任务：
// 在common_taskvar表中增加步骤字段
ALTER TABLE pre_common_taskvar ADD COLUMN step TINYINT(3) UNSIGNED NOT NULL DEFAULT '0';
// 任务进度处理逻辑修改
class task_multistep {
public function csc($task) {
$steps = unserialize($task['step_config']);
$current = $this->get_current_step();
return ($current / count($steps)) * 100;
}
}
（2）任务自动发放实现：
// 添加定时任务检查
function task_auto_assign() {
$tasks = C::t('common_task')->fetch_all_auto_assign();
foreach($tasks as $task) {
$eligible_users = C::t('common_member')->fetch_eligible_users($task['condition']);
foreach($eligible_users as $uid) {
C::t('common_mytask')->insert(array(
'uid' => $uid,
'taskid' => $task['taskid'],
'status' => 0
));
}
}
}
4. 性能优化方案：
（1）勋章缓存机制：
// 使用Discuz缓存系统
$medals = memory('medal_list');
if(!$medals) {
$medals = C::t('forum_medal')->fetch_all();
memory('medal_list', $medals, 3600);
}
（2）任务查询优化：
// 使用联合查询替代多次查询
$taskInfo = C::t('common_task t')
->join('common_mytask m', 't.taskid=m.taskid')
->where(array('m.uid' => $_G['uid']))
->first();
5. 安全增强方案：
（1）任务申请验证增强：
// 在apply前增加安全验证
if(!submitcheck('tasksubmit')) {
showmessage('submit_invalid');
}
$seccheck = security::check('task_apply');
if(!$seccheck) {
showmessage('security_error');
}
