Add post/page from script problem

Hi,

I am testing creating new pages from script on a multisite installation. I’ve had a google into how to go about this and am mostly using the info from this previous forum post:

http://ww.wp.xz.cn/support/topic/inserting-posts-via-external-script

my code looks like:

<?php

//      error_reporting(E_ALL); //
        ini_set('display_errors', '1');
        ini_set('display_startup_errors',1);
        error_reporting(-1);

echo 'starting script';//

        include ('/usr/local/www3/wp-admin/load-scripts.php');
//        include ('/usr/local/www3/wp-admin/admin.php');
        include ('/usr/local/www3/wp-includes/post.php');
     //   include ('/usr/local/www3/wp-load.php');
//        include ('/usr/local/www3/wp-blog-header.php');
        include ('/usr/local/www3/wp-includes/ms-blogs.php');
//        include ('/usr/local/www3/wp-includes/functions.php');
//        include ('/usr/local/www3/wp-content/themes/mc/functions.php');
echo 'starting script';//

        $wpdb->set_blog_id(15);

//-- Set up post values
                $myPost = array(
                        'post_status' => 'publish',
                        'post_type' => 'page',
                        'post_author' => 0,
                        'post_title' => 'Test Post',
                        'comment_status' => 'closed',
                        'ping_status' => 'closed',
                );

echo 'new post array defined, now create new post';
                //-- Create the new post
                $newPostID = wp_insert_post($myPost);

?>

This is returning no error and exits with status 0. Any “echo” I put in for debugging after the includes section is not executed. Probably I’m doing something basic wrong, can anyone help at all?

thanks in advance, Andy.
