How to get Prev Post / Next Post working in 4.2.4?

[BirdOPrey5]

After restoring back to an original showthread.php file for VB 4.2.4 instead of the edits above instead do this edit-


Go to line 1356. after the { hit enter a few times for some blank lines.

Paste this code into the middle of the blank lines, save, and try again. I haven't tested it but I have a feeling it may work. Worst case you restore back to the original showthread.php file, it won't hurt anything.

PHP Code:

        $FIRSTPOSTID = $curpostid;
        $LASTPOSTID = $curpostid;

        // sort out which posts to cache:
        if (!$vbulletin->options['threaded_maxcache'])
        {
            $vbulletin->options['threaded_maxcache'] = 999999;
        }

        // cache $vbulletin->options['threaded_maxcache'] posts
        // take 0.25 from above $curpostid
        // and take 0.75 below
        if (sizeof($postorder) <= $vbulletin->options['threaded_maxcache']) // cache all, thread is too small!
        {
            $startat = 0;
        }
        else
        {
            if (($curpostidkey + ($vbulletin->options['threaded_maxcache'] * 0.75)) > sizeof($postorder))
            {
                $startat = sizeof($postorder) - $vbulletin->options['threaded_maxcache'];
            }
            else if (($curpostidkey - ($vbulletin->options['threaded_maxcache'] * 0.25)) < 0)
            {
                $startat = 0;
            }
            else
            {
                $startat = intval($curpostidkey - ($vbulletin->options['threaded_maxcache'] * 0.25));
            }
        }
        unset($curpostidkey);

        foreach ($postorder AS $postkey => $pid)
        {
            if ($postkey > ($startat + $vbulletin->options['threaded_maxcache'])) // got enough entries now
            {
                break;
            }
            if ($postkey >= $startat AND empty($morereplies["$pid"]))
            {
                $cache_postids .= ',' . $pid;
            }
        }

        // get next/previous posts for each post in the list
        // key: NAVJS[postid][0] = prev post, [1] = next post
        $NAVJS = array();
        $prevpostid = 0;
        foreach ($postorder AS $pid)
        {
            $NAVJS["$pid"][0] = $prevpostid;
            $NAVJS["$prevpostid"][1] = $pid;
            $prevpostid = $pid;
        }
        $NAVJS["$toppostid"][0] = $pid; //prev button for first post
        $NAVJS["$pid"][1] = $toppostid; //next button for last post

        $navjs = '';
        foreach ($NAVJS AS $pid => $info)
        {
            $navjs .= "pn[$pid] = \"$info[0],$info[1]\";\n";
        }
    }

    unset($ipostarray, $postparent, $postorder, $NAVJS, $postid, $info, $prevpostid, $postkey); 


(The above is code from threaded mode that I believe makes the next/previous links work.)
