Using this in the controller: $this->set('category_tree',
$category_tree);
Just produces this error: Undefined variable: category_tree in C:\wamp
\www\cake\app\controllers\nodes_controller.php on line 47
I think this is correct: $this->set('category_tree', $this->Node-
>generateNestedList('--',
null));
I have a similar bit of code in the same controller which seems to
work:
$this->set('nodeTypes', $this->Node->NodeType->generateList()); // in
the controller
<?php echo $html->selectTag('Node/node_type_id', $nodeTypes, $html-
>tagValue('Node/node_type_id'), array(), array(), true);?> // in the
view
The problem seems specific to the generateNestedList function, I just
can't work it out. The snippet from Othy is just to advanced for a
poor designer to understand ;(
Cheers,
Brett.
