I am trying to create a new article eventually from a form you would fill out. The contents of the form would then be part of the article which you could edit.
At this point all I want to do is create a new article with the name I specify. I am trying to use the Article and Title classes and use the function insertNewArticle(***) to accomplish this, but I keep getting database insert errors:
Here is my sample code:
$myTitle = new Title("Change Control Test");
$myArticle = new Article($myTitle);
$myArticle->onArticleCreate($myTitle);
$myArticle->insertNewArticle( "A test article", "Just Testing", FALSE, FALSE );
And the error:
A database error has occurred Query: INSERT INTO `cur` (cur_id,cur_namespace,cur_title,cur_text,cur_comment,cur_user,cur_timest amp,cur_minor_edit,cur_counter,cur_restrictions,cur_user_text,cur_is_red irect,cur_is_new,cur_random,cur_touched,inverse_timestamp) VALUES (NULL,'0','','A test article','Just Testing','1','20051013212242','0','0','','Mharris','0','1','0.0116757728 88','20051013212242','79948986787757') Function: Article::insertNewArticle Error: 1062 Duplicate entry '0-' for key 2 (localhost)
Backtrace:

What is the best way to create a new article from an extension? I am using mediaiwiki 1.4.10.
Thanks,
Mike

You might want to look at the existing code for how title objects are created. There are factory functions for this.

I've been wondering for a while why the code above doesn't work. It looks much nicer than Title::newFromText(). Why can't we have sensible constructors for Title and User?
Of course, I'm the perpetrator of horrible entities such as Database::newFromParams(), but in my defence, I was just trying to fit in.

It probably would be reasonable, but we'd need to change some stuff. It doesn't work now. :)
One of the reasons we use static factory methods in various places is to provide semantically clear alternatives when there are mutliple different ways; for instance on Titles things get handled differently depending on whether the source text is from a URL or from wiki text. Or... something like that.
That one's a little confusing; others are clearer, eg taking an id number versus a name, or whatever.

You are aware of [[m:Help:Inputbox]] http://meta.wikimedia.org/wiki/Help:Inputbox, correct?

Do you have code to check that the user is actually allowed to create the article? Article::insertNewArticle() doesn't do this (in 1.5 or 1.4).
And the error:
A database error has occurred Query: INSERT INTO `cur` (cur_id,cur_namespace,cur_title,cur_text,cur_comment,cur_user,cur_timest amp,cur_minor_edit,cur_counter,cur_restrictions,cur_user_text,cur_is_red irect,cur_is_new,cur_random,cur_touched,inverse_timestamp) VALUES (NULL,'0','','A test article','Just Testing','1','20051013212242','0','0','','Mharris','0','1','0.0116757728 88','20051013212242','79948986787757') Function: Article::insertNewArticle Error: 1062 Duplicate entry '0-' for key 2 (localhost)
The sound of the error would indicate that you already have an article by that name (ie, your extension should check if the article exists before working). I also noticed that the cur_title is '' (empty string), so the article will likely be inaccessable.

Is ChangeControlExtension.php your thing?

The EditPage class if you really feel like having kludges and hacks around.
