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;
  }
