DEDE问答(ask)模块游客匿名提问和解答
先说一下实现后的效果，首先这个修改后是一个精简版的dedecms问答系统，会取消采纳答案等功能，因取消会员功能后不再有答案的等级之分，如对答案的平分功能等将被取消。
最后不建议使用匿名提问功能，建议使用会员功能来实现问答。这里是给大家提供一个学习的思路！
下面说一下方法：
post.php文件
if(empty($uid) && $action != 'rate')
{
showmsgs('no_login','../member/login.php?gourl=../ask/');
exit;
}
|
1，修改成 或注释掉
if(empty($uid) && $action != 'rate')
{
if($action!='ask' & $action!='')
{
showmsgs('no_login','../member/login.php?gourl=../ask/');
exit;
}
}
|
2，注释掉
/*if($question['uid'] == $uid)
{
showmsgs('asker_cannot_answer', '-1');
}else*/
3，然后
if($answer['uid'] != $uid)
{
showmsgs('unallowed_action', $backurl);
}else
替换成
if($question['uid'] == $uid)
{
showmsgs('asker_cannot_answer', '-1');
}else
|
这样就不能修改答案了，不过这个提示是不会回答自己的问题。
或者直接注释掉：修改答案部分的php代码。
else if($action == 'modifyanswer')
{
$answer = $dsql->getone("SELECT answer.id, answer.uid, ask.dateline, ask.solvetime, ask.status, ask.expiredtime FROM `dede_askanswer` answer left join dede_ask ask on ask.id=answer.askid WHERE answer.id='$id'");
if($answer)
{
if($answer['uid'] != $uid)
{
showmsgs('unallowed_action', $backurl);
}elseif($answer['status'] != 0)
{
showmsgs('question_solved', $backurl);
}elseif($answer['expiredtime'] < $timestamp)
{
showmsgs('question_expired', $backurl);
}
} else
{
showmsgs('question_nonexistence');
}
if(trim($content) == '')
{
showmsgs('post_answer_isnull');
}
if(strlen($content) > 10000)
{
showmsgs('post_answer_toolong');
}
if(strlen($brief) > 200)
{
showmsgs('post_brief_toolong', '-1');
}
if($dsql->ExecuteNoneQuery("update dede_askanswer set content='$content', brief='$brief' where id='$id'"))
{
showmsgs('modifyanswer_success',$backurl);
}else
{
showmsgs('modifyanswer_failed',$backurl);
}
}
question.php
注释
if($question['uid'] == $uid)
{
$publisher = 1;
}
