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

[edit]
Latest comment: 13 years ago2 comments2 people in discussion

i just did this to quickly get things going for our site and will improve later.

  • 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.

Hack for mysql works great thanks! --198.187.27.5 18:18, 17 June 2011 (UTC)Reply

Callback issue with 1.17.x

[edit]

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: 

public static function registerHook( &$parser ) {
        #### $parser->setHook( 'rt', array( 'RT::render' ) );
        $parser->setHook( 'rt', array( 'RT', 'render' ) );
        return true;
}

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

Updated for mysql on 1.23

Latest comment: 10 years ago2 comments2 people in discussion

The newer version of this extension splits RT.php into two files. The RT.php for mysql above seems not to work on Mediawiki 1.23, so here is an update:

This extension seems to be unmaintained. Perhaps it is an idea to take over maintainership and apply for commit access to the WMF repo. Cheers --[[kgh]] (talk) 19:19, 7 June 2014 (UTC)Reply
