Collapsable First Post using AJAX (or Last Post!)
Mod Version: 1.2.1, by magnus

---

---

---

Keywords: FORUMDISPLAY, search, results, collapse, AJAX, collapsable, first, last, unread, post

Description:
Allows you to expand/collapse the first, last or first unread post of a thread from FORUMDISPLAY and search results without the need to load the entire thread.

Details:
Upon perusing the wonderful deals over at http://www.slickdeals.net, I noticed this nifty feature which caught my eye. I found it quite useful as most people have a bad habit of not being very descriptive with their thread titles. This little trick made my browsing experience much more enjoyable, so naturally I had to borrow [read: shamelessly rip] the idea.

Please note that no additional queries are added, unless using the 'First Unread Post' option. Otherwise, the only queries performed are the same as those when a thread is normally viewed.

The magic behind this modification is performed by http://jquery.com/.

Usage:
Simply click the expand icon [+] in front of the thread title to expand, and the collapse icon [-] to collapse. Rocket science, eh?

---

Installation:

1. Download and unzip the ajax_first_post.zip archive.
2. Upload necessary files to their respective locations. (Attention custom style users! Be sure to upload the images to your custom image directory.)
3. Import the product-ajax_first_post.xml via the Product Manager.
4. Make any desired configuration changes via AdminCP > vBulletin Options > Collapsable First Post using AJAX
5. ???
6. Profit!

Notes:
All template modifications are made automatically. They attach to pretty common text locations, so modified styles shouldn't* be a problem.

However, for those who wish (or need) to perform the edits manually, you can find that information here

For those who have problems with the automatic template edits, or who just like to do things the hard way, here are the template edits required:

First, disable the automatic template edits:

• Browse to AdminCP > vBulletin Options > Collapsable First Post Using AJAX Options
• Select No for Enable Automatic Template Editing

Now perform the following template edits:

In FORUMDISPLAY -

FIND:

HTML Code:

$headinclude

ADD AFTER:

HTML Code:

<script type="text/javascript" src="clientscript/jquery.js"></script>
<script type="text/javascript" src="clientscript/vbulletin_vbpost.js"></script>

---

In search_results -

FIND:

HTML Code:

$headinclude

ADD AFTER:

HTML Code:

<script type="text/javascript" src="clientscript/jquery.js"></script>
<script type="text/javascript" src="clientscript/vbulletin_vbpost.js"></script>

---

[CHANGED IN 1.2] In threadbit -

FIND: (should be the first line)

HTML Code:

<tr>

REPLACE WITH:

HTML Code:

<tr<if condition="empty($ajax_firstpost_excluded) || !in_array($forumid, $ajax_firstpost_excluded)"> <if condition="$vbulletin->options['ajax_firstpost_firstlast']">id="vbpostrow_$thread[lastpostid]"<else />id="vbpostrow_$thread[firstpostid]"</if></if>>

FIND:

HTML Code:

		$thread[title_editable]
		<div>

ADD AFTER:

HTML Code:

				<if condition="empty($ajax_firstpost_excluded) || !in_array($forumid, $ajax_firstpost_excluded)"><img id="vbpostimg_<if condition="$vbulletin->options['ajax_firstpost_firstlast']">$thread[lastpostid]<else />$thread[firstpostid]</if>" src="$stylevar[imgdir_button]/expand.gif" onclick="return vbpost_get(<if condition="$vbulletin->options['ajax_firstpost_firstlast']">$thread[lastpostid]<else />$thread[firstpostid]</if>)" onMouseOver="this.style.cursor='pointer';" /></if>

Close

  i have the same problem. when passivevid is enabled, i get
  

  Code:

  Warning
  : Invalid argument supplied for foreach() in
  /includes/class_postbit.php(296) : eval()'d code
  on line
  39

  

  Ok, here's a fix. This is for passiveVid - (YouTube, Myspace, Google...) Not BBCODE users ONLY.
  
  In AdminCP > Plugins & Products > Plugin Manager, look for passiveVid - Showthread Replacement under Product : passiveVid and select [Edit].
  
  FIND:
  

  PHP Code:

                 foreach ($passiveVid as $k => $v) {
                   if ( $this->registry->options['passiveVid_sites'] & $v['id'] ) {
                       $this->post['message'] = preg_replace_callback($v['string'],create_function('$matches',$v['replacement']),$this->post['message']);
                       
                   }
               } 


  REPLACE WITH:
  

  PHP Code:

                 if ($passiveVid) {
                   foreach ($passiveVid as $k => $v) {
                       if ( $this->registry->options['passiveVid_sites'] & $v['id'] ) {
                           $this->post['message'] = preg_replace_callback($v['string'],create_function('$matches',$v['replacement']),$this->post['message']);
                       
                       }
                   }
               } 


  
  Disclaimer:
  Note that this was tested on my development board. I do not actively use passiveVid (or any video embedding tools) so I cannot be held responsible for any undesired effects that may occur as a result of making these changes.
  
  That being said, the changes simply check for the existence of a variable. There are no destructive functions being added or implemented, however, I just like to cover my rear.
