I have added a parser tag to make pretty links to the Mantis bug tracking system complete with a summary line. We use this on the XMMS2 wiki To easily reference Bug reports like on this page: [1]

For Mantis 1.1.2 with LDAP Auth., this extension in the initial Release didnt work for me, so I changed to direct Database access (MySQL only!). See Code Version 0.3 for details.

    // Note: You may need to add a line here to select the mediawiki database. Also, I had to remove the mysql_close line below.

}

Suggested Change: The current version does some odd text handling if used in lists. I altered the last few lines where the output is "wikified" to match a newer method illustrated in the mediawiki dev manual.

// change this:
$output = $parser->parse("[$bug_page $res]", $parser->mTitle, $parser->mOptions, false, false);

// to this:
$output = $parser->recursiveTagParse("[$bug_page $res]");

// and this: 
return $output->getText();

// to this:
return $output;
