Prevent Doubleposting

This is why i really want a Mini-Hack section here, please Chen

What this hack does:
When a User posts to a thread where he already has the lastpost, no new post will be added. The lastpost of him will be edited and the new text is put after his first message.
This would not be done, if he has an attachment in his new post or the old post is older than 1 hour (you can change this timespan yourself )

Known bugs: None

Hope someone can use it, i do

Believe this hack includes just 1!! codehack.

Heh, still did'nt work, well this is how it looks in the php file, can you see if its messed up there

PHP Code:

      $lastpost = $DB_site->query_first("SELECT * FROM post WHERE threadid = '$threadid' ORDER BY postid DESC");
      if($lastpost[userid]!=$bbuserinfo[userid] || (time()-$lastpost[dateline])>3600 || ($attachmentid and !$foruminfo[moderateattach])){
 $DB_site->query("INSERT INTO post 

(postid,threadid,title,username,userid,dateline,attachmentid,pagetext,allowsmilie,showsignature,ipaddress,iconid,visible) VALUES 

(NULL,'$threadid','".addslashes(htmlspecialchars($title))."','".addslashes($postusername)."','$bbuserinfo[userid]','".time()."','$attachmentid','".addslashes($mess

age)."','$allowsmilie','$signature','$ipaddress','$iconid','$visible')");
      } else {
            $editedbysql="";
            if ($showeditedby and $lastpost[dateline]<(time()-($noeditedbytime*60))) {
               $editedbysql=",edituserid='$bbuserinfo[userid]',editdate='".time()."'";
            }            
            unindexpost($lastpost[postid],$lastpost[title],$lastpost[pagetext]);
            $DB_site->query("UPDATE post SET dateline='".time()."',pagetext='".addslashes($lastpost[pagetext]."\n\n".$message)."' WHERE 

postid=".$lastpost[postid]);
            indexpost($lastpost[postid],0);
            $DB_site->query("UPDATE thread SET lastpost='".time()."' WHERE threadid='$threadid'");
            if ($visible) {
            $goto="showthread.php?s=$session[sessionhash]&postid=".$lastpost[postid]."#post".$lastpost[postid];
              } else {
            $goto="forumdisplay.php?s=$session[sessionhash]&forumid=$threadinfo[forumid]";
              }
              eval("standardredirect(\"".gettemplate("redirect_postthanks")."\",\"$goto\");");
              exit;     
      }

hmm, can't see whats wrong...

can you please highlight which of this line is the error producing line (as your errormsg says)

also please tell me the exact errormsg

[Mystislav]

Ok, here is the message

Fatal error: Call to undefined function: unindexpost() in /home/sjmadho/public_html/board/newreply.php on line 288

and the exact newreply is in the attactments .. thanks alot.

mystislav: edit your post, you are not allowed to post full vb-files here!!!

second: than the problem isn't my hack. you have to have made some mistakes some time ago, the function unindexpost() is defined in functions.php on every vb. If you don't have it, you have messed up your functions.php

[Mystislav]

Aight, so if I upload a new functions it should work?

Xenon,

Is there any way to add color to the DOUBLE POST FEATURE part of this line?

PHP Code:

$DB_site->query("UPDATE post SET dateline='".time()."',pagetext='".addslashes($lastpost[pagetext]."\n\nDOUBLE POSTING FEATURE\n\n".$message)."' WHERE postid=".$lastpost[postid]);
            indexpost($lastpost[postid],0); 


[Xenon]

@Mystislav: yes, then it should work.

@Boofo: You can use every vb-code in the textpassage between post1 and post2, so if you have enabled the color-bbcode on your board you should be able to do that:

PHP Code:

$DB_site->query("UPDATE post SET dateline='".time()."',pagetext='".addslashes($lastpost[pagetext]."\n\n[b][color=red]DOUBLE POSTING FEATURE[/color][/b]\n\n".$message)."' WHERE postid=".$lastpost[postid]); 


for example

[Boofo]

I had to replay to this message in order to see how you had the code (it was parsed here. The disable tags hack is great for this sort of thing!)

I was using [disable]<font color=\"yellow\"> and </font>[/disable]. That's where I messed up. Thanks for the fix.

[disable]$DB_site->query("UPDATE post SET dateline='".time()."',pagetext='".addslashes($last post[pagetext]."\n\nDOUBLE POSTING FEATURE\n\n".$message)."' WHERE postid=".$lastpost[postid]);[/disable]

I forgot to add in my last message (you see...they really need this here for this kind of thing. ).

Is there a way to have it say like:

DOUBLE POSTING FEATURE - (post subject here)

in case they enter a post subject in the added message?

And have it show:

DOUBLE POSTING FEATURE

by itself it they don't?

[Xenon]

ups, damn i forgot code is parsed in [php]-tags too

yes, Having the Subejct is also possible:

PHP Code:

[disable]$DB_site->query("UPDATE post SET dateline='".time()."',pagetext='".addslashes($lastpost[pagetext]."\n\n[b][color=red]DOUBLE POSTING FEATURE[/color][/b] - ".$title."\n\n".$message)."' WHERE postid=".$lastpost[postid]);[/disable]
