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; }
