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.

nope the unindex error you posted seems to be another problem
my hack doesn't change this function.

as you can read in the message unindexpost function isn't declared for some reason.
have you upload an unhacked version of functions.php

if problem stays you should open a thread in support forum

you have to edit newreply.php and change addslashes($message) into $message in the part of my hack..

when I search for this it appears 4 times in this order:

 if ($prevpost=$DB_site->query_first("SELECT attachmentid,postid,visible FROM post WHERE threadid='$threadid' AND username='".addslashes($postusername)."' AND userid='$bbuserinfo[userid]' AND title='".addslashes(htmlspecialchars($title))."' AND dateline>$datecut AND pagetext='".addslashes($message)."'")) {

      $DB_site->query("UPDATE post SET title='".addslashes(htmlspecialchars($title))."',pagetext='".addslashes($message)."',allowsmilie='$allowsmilie',showsignature='$signature',iconid='$iconid',attachmentid='$attachmentid' WHERE postid='$postid'");

$DB_site->query("INSERT INTO post (postid,threadid,title,username,userid,dateline,attachmentid,pagetext,allowsmilie,showsignature,ipaddress,iconid,visible) VALUES (NULL,'$threadid','".addslashes(htmlspecialchars($title))."','".addslashes($postusername)."','$bbuserinfo[userid]','".time()."','$attachmentid','".addslashes($message)."','$allowsmilie','$signature','$ipaddress','$iconid','$visible')");

$DB_site->query("UPDATE post SET pagetext='".addslashes($lastpost[pagetext]."\n\n".addslashes($message))."' WHERE postid=".$lastpost[postid]);

any idea which one I should change?

Thanks a lot! It worked great!

How could I make certain usergroups like mods/super mods/admins excempt from this rule? Meaning so that members can't double post but they can. And could it be a toggle so they could choose to bypass it or not?

[Xenon]

the first thing is easy:
find

PHP Code:

      if($lastpost[userid]!=$bbuserinfo[userid] || (time()-$lastpost[dateline])>3600 || ($attachmentid and !$foruminfo[moderateattach])) { 


and just add the usergroupconditions:

PHP Code:

      if($bbuserinfo['usergroupid'] ==6 || $bbuserinfo['usergroupid'] ==7 || $bbuserinfo['usergroupid'] ==5 ||$lastpost[userid]!=$bbuserinfo[userid] || (time()-$lastpost[dateline])>3600 || ($attachmentid and !$foruminfo[moderateattach])) { 


a toggle would also be possible (with a bit more work), but i don't see the effect there?
i mean if they want to add it to the last post mods should be able to edit

I love this hack, excellent work Xenon

as you know everything is possible

go to admin/settings.php and create new setting variablename: stopdoublepost
function to create: yesno

and then just before

PHP Code:

$lastpost[userid]!=$bbuserinfo[userid] || 


in newreply.php add this:

PHP Code:

!$stopdoublepost || 


I think I am missing something here ... how exactly do I create this variable? I don't see it :$

[Xenon]

you have to go to admin/settings.php

there you can set up a new vb-option called stopdoublepost.
just add yesno to the field function to create...

after that you'll have a new option in your vb-options within acp

Ok, I am sorry to sound dumb, but how exactly do I do that? There are several sections in the file. Where and how do I add it? Does it go under "start add" or someplace else? And is it like the makeinputcode thing?
