If anyone's curious, I figured this out myself using the
Bump Threads mod. It's very simply to make hitting thanks bump the thread.
First, open post_thanks.php. Find this line:
PHP Code:
if ($_REQUEST['do'] == 'post_thanks_add')
Inside that if block, find this line:
PHP Code:
if ($using_ajax)
Right above that line, add this small chunk of code:
PHP Code:
$threadman =& datamanager_init('Thread', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
$threadman->set_existing($threadinfo);
$threadman->set('lastpost', TIMENOW);
$threadman->save();
The thread will now be bumped to the top upon hitting thanks.
A note to the mod writer: this is a handy feature, and it'd be trivial to add an option in the admin panel to enable/disable the bumping of threads upon hitting thanks. Love the plugin.
[edit]
By the way, I'm on a 3.7.3 PL1 install for what it's worth.
