Collapsable First Post using AJAX (or Last Post!)

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 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 jQuery: The Write Less, Do More, JavaScript Library.

[hr]-[/hr]
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.

I get an error message when I try. The plus sign is there, but what I see is "There was an error. Please try again."

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:
ADD AFTER:

[hr]-[/hr]
In search_results -

ADD AFTER:

[hr]-[/hr]
[CHANGED IN 1.2] In threadbit -

FIND: (should be the first line)
REPLACE WITH:

ADD AFTER:

Hrm.. that error appears when the script is unable to pull data. However, I tested the backend on your site and it seems to be working: http://www.4x4mecca.com/forum/vbpost...p?postid=12979

Let me nose around a bit.

@4x4 Mecca:

Redownload the archive and upload/overwrite your existing vbpost_ajax.php with the new one. Let me know if that fixes it.

Thanks! I just edited the teplates manually just incase that was the problem. It still isn't working.

Error is still there. Any idea what might be interfering?

same for me

Ok, I removed the download link for a second while I try and track this down. My apologies.

I have a few (read maybe a lot) hacks installed, but I don't know which one could be messing with it. Anyone else recreate this on their own site?

THANKS M8 nice work :)

this is also giving a javascript error in newposts

Wait, you get an error when trying to write a new post? I don't see how this could affect that. What's the error?

no i get the error like the poster above me and also in do=getnew

I didn't get an error when making a new post or new reply.

and also in do=getdaily

where is the new file ?

uploaded

Still not working, and errors on get new posts too.

sorry, nothing changed

Do me a favor, check to see if you have a vbpost_postbit template..

Yes, I do.

I do

This is odd.. for some reason or another, it's not being displayed. I installed a fresh vB and imported this product and it worked fine. There has to be a hack conflict somewhere.

Is there any way another mod could be creating this problem?

Nice addon, great job!

Question.
When a user hits the (+), does it add to the thread view count? Because I don't see it adding in your screenshots.

No.

Hm, can you please add an option that allows that?

done, uploaded again.

still the same for me

still errors :(

This is so hard to do remotely.. lol.

I am using vbseo if that means something

I developed this on a forum using vBSEO. That shouldn't be a problem.

the image code I had to add manually in templates because of vbplaza

Ok, upload this file. This isn't going to fix it, it's to give me more information. I'm going to need you to delete it as soon as I'm done.

after giving the alert, the image ajaxsmall.gif still displays and i must refresh to stop it
