Work In Progress: Create nice news URLs

Hi,

It is made to suit my needs, and it works fine on test server (WBPortable) but I would like to hear about some vulnerabilities and comments before I post the tutorial

Here what is it about:

As of now, you can put each news post into certan group, but their links are all presented as www.wburl.xy/posts/this-is-the-news-title-10.php (at all my sites there is no /pages folder, and 10 is post_id)

So if you have multiple categories, all your news url's will be presented as boring - - -/posts/- - - folder.
This patch will create links like: www.wburl.xy/football/this-is-the-football-news-10.php , where football is your news Group (category)

How it works:
1. When you create news Group it will create folder /group_name/ under /Pages
2. When you add news you can select group to: None, or select some Group. If you select None, news will be created under /posts/ and if you select any group it will go to /group_name/ folder. When you move between None or Groups it is the same.
3. If you delete Group, php files (of Pages and News ) will still be there
4. There are no problems when adding Page with same name as Group_name unless you really want to be nasty and put the exact post_id at the end.. (Set under TO DO)
Example: page: this-is-title.php , news: this-is-title-9.php , but if you add 9 at modify page name it will overwrite the code in file..
5. When you delete Page ,with or without Pages or News in it, which is same name as your Group title, code will check if there are News posts in it and it will not delete the folder but only the file (page_name.php and not the /page_name/ ) and entry in DB so you will not see that page in Admin Pages

TO DO:
At this moment it is still under testing and I have to make that if you create same pagename as news title it will overwrite the code in the file when you put it in same dir

So what do you think ?
