Improved Thread Preview Hack

The idea for this hack was originally that of Parker Clack, a regular here on vBulletin.org.

What this hack does:
Basically, this hack pops up a little box/window when the mouse is run over a thread title that shows the first three hundred characters of the first post in the thread (that is, the post that started the thread).

Improvements to Parker Clack's hack:

• Far, far less code...
• Easier installation (one file edit, one template edit)...
• Less space usage...the beginning of the first post in each thread is not stored twice - only once now!...

Versions:
3.0: Overgrow's search page thread preview instructions.
2.1: Added some necessary instructions.
2.0 Reduced MySQL queries significantly.
1.0 Initial release.

Comments appreciated...

A version for vbHacker is available here - note: some files may need fixing afterward if they present parse errors!

How to Censor Previews (by nakkid)
See page seven of this thread.

A very important security fix is available here - I have not updated the ZIP, so install it after you install the hack

I had tried installing this and kept getting compile errors or something (I'm an ASP'er, not a PHP'er, gimme a break).

Line 991 I'm told. Line 991 is this:

$searchresult[message]=censortext(searchresult[pagetext]);

So I looks around and I realise it should read like this instead:

$searchresult[message]=censortext($searchresult[pagetext]);

In the instructions > the threadpreview search .txt file > at the very bottom in the template change part, its missing a $ before fppreview

Didnt read the whole thread to see if anyone else brought it up, thanks.....

After 3/4 months of usage, my users think this was the best hack EVER, so thanks again to Parker for the original idea and nicksaunders/freddie for perfecting it

replace with:

PHP Code:

$fppreview=str_replace("[img]","",$fppreview);
$fppreview=str_replace("[/img]","",$fppreview);
$fppreview=str_replace("[url]","",$fppreview);
$fppreview=str_replace("[/url]","",$fppreview);
$fppreview=str_replace(""","",$fppreview); 


I made these changes in search.php also but doesnt work, it still ignores any text between "[" and "]"

Applying those changes in forumdisplay worked fine. any ideas?

I hope nicksaunders doesn't mind, but I've made a small modification to this hack. The purpose of the mod is to add an on/off switch the user can set via the User CP/Edit Options, so he/she can decide to use this feature or not. I did this because some of my users said they didn't like it.

I have attached the modification instructions to this post. These instructions DO NOT include instructions for the base hack; they assume that you have already installed this hack, and show you what to do AFTER that. These will be meaningless if you have not already installed the original base hack!

nicksaunders, if you would like to include this modification in the official version of this hack, by all means, please feel free. If you do, I suppose it would be nice to have my name up there with "nicksaunders, freddie, Overgrow, & Parker Clack"...
