如何使用基于HTML表单输入的预加载文本创建新的MediaWiki文章？

I'm creating a private wiki using MediaWiki and have a Special page with HTML added to create a sort of template entry page. When the user submits the input I would like to create a new WikiPage filled out with the input text in a similar format to my template. I have been playing around with Semantic Forms and it does a great job of allowing template/form actions but its still not quite perfect. The wiki requires only two main page templates so I want to just create them myself and make it an incredibly simple user interface for others. Can I do this with only HTML and PHP or do I need some helper JavaScript? How do I save the data from the forms and programmatically generate a new WikiPage with it in PHP? I've done the new WikiPage(...) and tried new Article(...) but I assume I still need to interact with the database.

edit.php can create an article for you and the source code is short and easy to understand.

You'll need to do new WikiPage() and then doEditContent, you could try looking at this simple code in an extension https://github.com/mkroetzsch/AutoCreatePage/blob/master/AutoCreatePage.php#L123 which automaticaly creates pages, if not created. Documented here https://www.mediawiki.org/wiki/Extension:AutoCreatePage

Minimal code:

$title = Title::newFromText( 'Desired page title goes here' );
if ( !is_null( $title ) && !$title->isKnown() && $title->canExist() ){
    $page = new WikiPage( $title );
    $content = ContentHandler::makeContent( 'Page content goes here', $title );
    $page->doEditContent( $content, 'Edit summary goes here' );
}
