Auto-creation of threads?

[Wired1]

But I can only use $post['threadid'] and $post['postid'] after the build_new_post is hit in the code, correct? I think that'll save me 1 query

This look right?

PHP Code:

// Load vB-Backend 
require('./global.php'); 
require('./includes/functions_newpost.php'); 

$userid = 5; // The user creating the thread 
$forumid = 10; // The forum where the thread should be posted 

// Get forum & user info 
$foruminfo = fetch_foruminfo($forumid); 
$bbuserinfo = fetch_userinfo($userid); 

// Setup the thread 
$post[title] = 'Some foobar sssstitle'; 
$post[message] = 'Some foobar message text'; 
$post[poststarttime] = TIMENOW; 
$post[posthash] = md5($post[poststarttime] . $bbuserinfo['userid'] . $bbuserinfo['salt']); 
$post['emailupdate'] = 9999; 

// build the thread 
build_new_post('thread', $foruminfo, array(), 0, $post, $errors); 

// Errors? 
if (sizeof($errors) > 0) { 
  // error processing 
}
ThreadID = $post['threadid']; 
PostID = $post['postid']; 


ThreadID and PostID are columns in a table I have created.
