[Mediawiki-l] Create an article using an extension

Hi MediaWiki-User and Developer,

I'm using an extension for parsing an external document. This works fine, but now I want to insert the content of a variable as a new article. So I took a look at maintenance\importTextFile.php as recommended and tried to write a new article using

require_once( 'importTextFile.inc' ); .... insertNewArticle( $title, $text, $user, $comment, $rc );

after testing if the article exists and the user is allowed to write new articles.

But I receive the following message:

Fatal error: Call to a member function exists() on a non-object in importTextFile.inc on line 24

What does this mean? Or is there a other way to create new articles using an extension.

Thanks in advanced
