Prevent Doubleposting

When a User posts into 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 will be done until the old post is older than 24 hours (you can change this timespan yourself)

Nothing more to say about that, it's the quite same as my vb3.0 version.

This Mod should run with 3.6 as well


** Please make sure you ENABLE this product after you install it - it is disabled by default. **

For vb 3.8 there are two alternative updates ;

Very nice hack! I have used Paul M's fix, but the time only changes on the post itself. So in "new post" searches it doesn't show up and the wrong time is still displayed on the "lastpostby" bit in the forumdisplays.

Anyone know how to change that so the automerged post will turn up as a new post in searches? Thank you.

This is a great modification, but is there any way to disable it for certain forums, as some forums require double posting rapidly.

i dont know if anything has been posted in this thread about that, so if it has im sorry.

any help would be very much appreciated.

I used the code based off someone's plugin posted a few pages back. I removed the time checking so it would always merge their last post, however it would update all the times so it acted as if it was a new post in the thread.

In the postdata_presave I added the following with all the other set's:

PHP Code:

$this->set('dateline', TIMENOW); 


Here is all of my code in the postdata_postsave, you can see how you have to update both the thread time & forum time:

PHP Code:

if ($this->isdoublepost)
{
    // Add Edited By Note
    $this->dbobject->query_write("
        REPLACE INTO " . TABLE_PREFIX . "editlog (postid, userid, username, dateline, reason)
        VALUES (" . $this->fetch_field('postid') . ", " . $this->fetch_field('userid') . ", '" . $this->dbobject->escape_string($this->fetch_field('username')) . "', " . TIMENOW . ", '" . $this->dbobject->escape_string('Automerged Doublepost') . "')
    ");

    // Update Last Posted In Thread
    $thread =& datamanager_init('Thread', $this->registry, ERRTYPE_SILENT, 'threadpost');
    $thread->set_existing($this->info['thread']);

    $thread->set('lastpost', TIMENOW);
    $thread->set('lastposter', $this->fetch_field('username'));

    $thread->save();

    // Update Last Posted In Forum
    $forumdata =& datamanager_init('Forum', $this->registry, ERRTYPE_SILENT);
    $forumdata->set_existing($this->info['forum']);
    $forumdata->set_info('disable_cache_rebuild', true);

    $forumdata->set('lastpost', $this->fetch_field('dateline'));
    $forumdata->set('lastposter', $this->fetch_field('username', 'post'));

    $forumdata->set('lastthread', $this->info['thread']['title']);
    $forumdata->set('lastthreadid', $this->info['thread']['threadid']);
    $forumdata->set('lasticonid', ($this->info['thread']['pollid'] ? -1 : $this->info['thread']['iconid']));

    $forumdata->save();

    // Set Redirect
    $postid = $this->fetch_field('postid');
    $this->registry->url = 'showthread.php?' . $vbulletin->session->vars['sessionurl'] . "p=$postid#post$postid";
    eval(print_standard_redirect('redirect_doublepost', true, true));
} 


The reason the forum & thread do not get updated is because an "edit" creates the $this->condition and thus the other two queries will not run automatically.

Hope this helps.

I have modified the code as follows:

$post['message'] = $doublepost['pagetext'] . $dp_settings['spacer'] . " $vbulletin->userinfo[username] added " . intval((TIMENOW - $doublepost[dateline]) / 60) . " minute(s) " . intval((TIMENOW - $doublepost[dateline]) % 60). " seconds later...\n\n" . $post['message'];

No matter what I try I cannot get it to display the username in the comment, can someone help me?

PaulM ur fix not workin when upgraded to 3.5.3

Fatal error: Call to undefined function: build_thread_counters() in c:\program files\easyphp1-8\www\forum\newreply.php(530) : eval()'d code on line 14

Actually, the database error causes the double merge:

The QR AJAX JS gets the database error and attempts a repost.

This one works in an interesting way, too. (Attachment link.) I've just tested it on my test board, and it merges all posts without paragraph breaks, which doesn't look too good.

I seem to recall that you're not developing this as a plugin, but just in case...

[EasyTarget]

you go to the vbulletin options and you can add linebreaks or whatever you want to do.

[IrPr]

any suggestion ?

im got this fatal error when upgrade my board to 3.5.3 and do PaulM's code modifications

[PersianImmortal]

I got this to work on my 3.5.3 board (TweakGuides Forums) by using the original code, modifying as provided by Paul M, and also adding one new feature I think is very useful. This code works with AJAX (e.g. Quick Reply) without any problems, it automatically refreshes the page:

PHP Code:

// ########### Xenon Modified Prevent Doublepost Hack #########
    $dp_settings = array(
        'timespan' => 3600 * 24, // how many seconds after the last post the new post is defined as doublepost (default: 24 hours)
        'spacer' => "\n\n [b]Additional Comment:[/b] \n",    // What should be between the old post and the new one (default: two empty lines). Note: PersianImmortal has added [b]Additional Comment:[/b] \n to make it clear what is being added each time - can be removed if you wish.
        'editedbymsg' => '[Automerged Doublepost]', // If left blank no edited by will appear
    );
    
    $isdoublepost = false;
    $oldmsg = $post['message'];

    if ($type != 'thread' 
        AND $threadinfo['lastpost'] > TIMENOW - $dp_settings['timespan'] 
        AND $threadinfo['lastposter'] == $vbulletin->userinfo['username'])
    {
        // we are here, so we may have a doublepost -> do more exact checkings
        $doublepost = $vbulletin->db->query_first("
            SELECT post.*

            LEFT JOIN " . TABLE_PREFIX . "deletionlog AS deletionlog ON(deletionlog.primaryid = post.postid AND type = 'post')
            WHERE threadid = $threadinfo[threadid]
                AND dateline > " . (TIMENOW - $dp_settings['timespan']) . "
                AND visible = 1 AND deletionlog.primaryid IS NULL
            ORDER BY dateline DESC
            LIMIT 1
        ");
    
        if ($doublepost['userid'] == $vbulletin->userinfo['userid'])
        {
            // we truely have a doublepost, now check if the merged post still fits the rules!
            $dataman2 =& datamanager_init('Post', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
            $dataman2->set_existing($doublepost);
            $post['message'] = $doublepost['pagetext'] . $dp_settings['spacer'] . $post['message'];
            
            // set info
            $dataman2->set_info('preview', $post['preview']);
            $dataman2->set_info('parseurl', $post['parseurl']);
            $dataman2->set_info('posthash', $post['posthash']);
            $dataman2->set_info('forum', $foruminfo);
            $dataman2->set_info('thread', $threadinfo);
    
            // set options
            $dataman2->setr('showsignature', $post['signature']);

            // set data
            $dataman2->setr('pagetext', $post['message']);
            $dataman2->setr('iconid', $post['iconid']);
    
            $dataman2->pre_save();
            if (!$dataman2->errors)
            {
                // merged post is ok, so do merging
                $isdoublepost = true;
                unset($dataman);
                $dataman =& $dataman2;
                $post['postid'] = $doublepost['postid'];
            }
            else
            {
                // merging will produce errors so keep it as a single post..
                $isdoublepost = false;
            }
        }
    }
    
if ($isdoublepost)
    {
        // Ugly hack added by Paul M to fix ajax merge //
        if (!$vbulletin->GPC['ajax'])
        {
            $id = $doublepost['postid'];
            $dataman->save();
        
            if ($dp_settings['editedbymsg'] != '')
            {
                $vbulletin->db->query_write("
                REPLACE INTO " . TABLE_PREFIX . "editlog (postid, userid, username, dateline, reason)
                VALUES ($id, " . $vbulletin->userinfo['userid'] . ", '" . addslashes($vbulletin->userinfo['username']) . "', " . TIMENOW . ", '" . addslashes($dp_settings['editedbymsg']) . "')
                ");
            }
        }
        $vbulletin->url = 'showthread.php?' . $vbulletin->session->vars['sessionurl'] . "p=$post[postid]#post$post[postid]";
        eval(print_standard_redirect('redirect_postthanks', true, false));
    }  
    else
    {
        // no doublepost so save as new post
        $post['message'] = $oldmsg;
        $id = $dataman->save();
    } 


In summary the modifications to the original code are firstly the second step provided by Paul M (comment tags show Paul's added code as he provided it) - this is necessary for the AJAX refresh to work properly.

I also added an Additional Comment: heading in the Spacer, so that each automerged reply looks like this:

Additional Comment:
Second post text merged into first post

Additional Comment:
Third post text merged into first post

That way it becomes obvious what's been merged, both to the user and the reader. Also helps prompt the user to use the Edit button to add additional comments next time rather than just post multiple times in a row.

As I said, this now works perfectly on my board, and having tested it with both standard replies, quick replies using full AJAX features enabled, there are no errors or glitches.

Many thanks to Xenon and Paul M for this great mod, very useful and prevents a lot of conflicts and work for mods who get tired of having to merge multiple posts by individuals.

[IrPr]

Nice! but it works same as Andreas's Product
but PaulM's method don't need refreshing
