[bbDev] Re: Include bb from WP

After some further digging, I think now that $bbdb is created but simply
not available later. Queries in bb-settings.php after $bbdb is created
work; queries made later in functions.php do not. Making a new $bbdb like
in this code in functions.php made everything run smoothly.

if( !isset( $bbdb ) ) {
	$bbdb = new bbdb('','','','');
	$bb_table_prefix = 'bb_';
	$bb->wp_table_prefix = 'wp_';
	$bbdb->forums    = $bb_table_prefix . 'forums';
	$bbdb->posts     = $bb_table_prefix . 'posts';
	$bbdb->topics    = $bb_table_prefix . 'topics';
	$bbdb->topicmeta = $bb_table_prefix . 'topicmeta';
	$bbdb->users     = ( $bb->wp_table_prefix ? $bb->wp_table_prefix :
$bb_table_prefix ) . 'users';
	$bbdb->usermeta  = ( $bb->wp_table_prefix ? $bb->wp_table_prefix :
$bb_table_prefix ) . 'usermeta';
	$bbdb->tags      = $bb_table_prefix . 'tags';
	$bbdb->tagged    = $bb_table_prefix . 'tagged';
}

An issue of scope? Declaring global $bbdb before db.php is loaded instead
also makes everything run smoothly. However I don't know why loading WP
first should affect the scope or $bbdb anyway. Does anyone know?

Anyway, solution: putting global $bbdb; in bb's config.php file.
