You're never evaluating $threadfields anywhere.  Of course it won't work - your PHP code doesn't even have a mention of $threadfields.

The general gist of things is to have something like

PHP Code:

$url = get_xta_url($thread);

---

and use {$url} in templates, although that doesn't solve everything.  I'm just not really in the mood for custom coding at the moment...
