Hi,

I've just signed up for the list but searched the archives yesterday
for help with my issue and couldn't find what I was looking for...

I've just started exploring DB_NestedSet (using the latest beta) and
I'm having some trouble working out how to get it to produce output for
a particular branch. I have a database set up and scripts in place that
produce a tree using the Menu output option when I use:

$data = $nestedSet->getAllNodes(true);
$params = array(
'structure' => $data,
'titleField' => 'name',
'urlField' => 'href');
$output =& DB_NestedSet_Output::factory($params, 'Menu');
$structure = $output->returnStructure();
print_r($structure);

but I can't work out how to get it to do the same for, say, all the
children of the node with ID 2. I tried:

$data = $nestedSet->getSubBranch(2,true);
$params = array(
'structure' => $data,
'titleField' => 'name',
'urlField' => 'href');
$output =& DB_NestedSet_Output::factory($params, 'Menu');
$structure = $output->returnStructure();
print_r($structure);

but the only output I get from this is "Array ( )"

If anyone can provide me with any pointers I'd be very grateful.

thanks. James.

Right - the output driver seems to demand a root node as starting point.
I haven't looked into this code for some time but I will try to fix this
with the next relase.
GetBranch will work btw.
