Extension talk:RT

Hey-

Looks like this only works with RT using Postgres, not with MySQL? It doesn't explicitly say so anywhere, but it appears the pg_connect is only for postgres, and hence this extension is limited to Postgres based RT installations.

quick / dirty mysql hack to RT.php
i just did this to quickly get things going for our site and will improve later. --Erikvw 12:14, 1 June 2009 (UTC)
 * all my comments are marked with erikvw
 * original code remains in the file, just commented out with ####
 * requires a few extra parameters instead of just the $wgRequestTracker_DBconn
 * $wgRequestTracker_DBhost=
 * $wgRequestTracker_DBuser=
 * $wgRequestTracker_DBpasswd=
 * $wgRequestTracker_DBdbname=
 * mostly change pg_ to mysql_, mysql does not have mysql_fetch_all, mysql can be case sensitive on table names
 * use date_format and concat in main sql string instead.

Callback issue with 1.17.x
I'm using PHP 5.3.2.

I ran into the following error when trying to submit a wiki entry with the rt tag: Tag hook for rt is not callable.

It turns out in RT_body.php, PHP didn't like the way the callback function was passed. Here is the relevant code:

I commented out the offending code. After this change everything worked as expected.
