WordPress MU

Hi
I'm developing a PHP function that should create a page in a specific blog. I've started from wp_insert_post and modify it to insert just pages.
Basically I make some insert in the following tables:
- wp_11_posts where a write page content, author, status = publish , permalink i need ....
- wp_11_postmeta where I insert post_id, _wp_page_template, default
- wp_11_categories where I insert post_id , 1 (category id)

In this way the page is created i can see it in the manage section of WP Consolle but i cannot view it using the permalink. I get 404 not found.
If, using the WP consolle i choose to edit the page and i save it without any modification than it works i can see it using the pemalink.
So there is some info missing , i need to store some more info somewhere.
I've tried to follow the consollo flow but it is difficult to understand page-new.php and page.php flow.
Any suggestions?
thanks
Paolo

Before you get any further, you may want to upgrade. *_categories is no longer.

it's difficult for me to male un upgrade of the whole site at this moment. could you pls give me an help on this problem. I really cannot figure it out

look in wp-includes/wpmu-functions.php where it sets up a new blog. See how it sets up the default About page.

Sounds like you're not creating the required rewrite rules for your new page, so Wordpress doesn't know that it exists as far as handling "public" requests for it. As andrea_r suggests, check out how the default About page is created, or just look further into the rewrite rules stuff (which I'll admit is a bit complex for me right now :)

I've found the mail problem. the global variable $wpdb contains all prefix and settings for blog number 1, I've tried to call "switch to blog" in order to load my blog tables but no effect , so i manually filled $wpdb variable like this:
$wpdb->prefix = $table_prefix;
$wpdb->blogid = $new_blog;
$wpdb->posts = $table_prefix . 'posts';
then it started working.
So I have created the page. The strange thing is the the guid i insert in the posts table is not respected. Pages responds to http://host/blogs/myblog/index.php?pagename=mypage.
I would like to change this permalink template to
http://host/blogs/myblog/mypage .
